Sun, Sea & My Girlfriends Sister 3

After an hour or so of paddling around in the water trying to find shells and cool rocks, it was now disappointingly time for us to put our clothes on. I watched wistfully as Lily squeezed her giant breasts back into her bikini top and her large round butt back into her bottoms. As we walked back, we did not mention the show Rose put on for her sister. Lily asked lots of questions about our relationship such as how we met and all the questions that she had never been too interested in before. With each question, she seemed quite genuinely interested and there was no awkwardness surrounding the fact that she had just watched her sister having sex right next to her.

The sun was low on the horizon as we approached their aunt and uncle's property. We could smell the dinner that their aunt had cooked in the air making our mouths water as we trotted up the lane.

"You were out all day, you must be exhausted!" Their aunt exclaimed. We all looked at one another nodding knowingly. "Did you go far?"

We nodded and slumped into the seats around the table. Their aunt chattered away while we all sat out on the veranda eating, drinking, and playing board games until the sun had thoroughly set and the garden lights had come on bathing us in a warm orange glow. Throughout the meal, Rose who was sitting across from me, and Lily who had been sitting on my left, had been occasionally rubbing up against my leg. They did this without the other one realising. More importantly, their Aunt and Uncle were none the wiser.

With a big sigh, their uncle got up, declared that he was going to bed and that if we were wanting to go to a cliff side monastery to eat lunch the following day we need to be getting up at a good time in the morning. Their aunt said she would go wash the dishes then turn in and recommended that we all go to bed as well. Rose offered to help with the dishes telling Lily and I to go on and get ready for bed without her. We wandered towards the cabin talking under our breath so no one would hear us.

"Will you visit me after she's gone to sleep?"

"Absolutely, I'll be with you as soon as she's snoring."

"Please don't make me wait long."

The sky, usually a vista of stars, was obscured by a thick cover of cloud. I made my way into the cabin and into the little bedroom, closing the door behind me. I got ready for bed, cleaned my teeth, and changed into my pyjamas. Climbing into bed I played on my phone while I waited for Rose. She arrived back 30 minutes later and started bustling around the room chattering away.

"It looks like it is going to rain," she said while stripping her clothes off and staring at herself in the mirror.

"Yeah, it's clouded over really fast," I replied, watching her nipples as she rubbed her potions and creams into her soft pink skin.

"My uncle was saying it doesn't usually rain here but when it does it's really heavy, which makes doing anything almost impossible."

"Well let's hope it doesn't come to that, I'm looking forward to going to this restaurant."

"Yeah I know, but we can always go the next day if it does rain."

"I can't imagine it would be that bad?"

"Well me neither, but I guess if it rains we will see."

She turned the light out and got into bed, wrapping herself up tightly, and closing her eyes. I waited 20 minutes until the usual sounds of her sleeping were obvious next to me.

"Rose?" I said knowing if she were actually asleep it would take a ship's foghorn, an earthquake, and the apocalypse to wake her up. I had known for years that she was not going to wake up for anything other than her own body telling her it was time to wake up.

I jumped out of bed, hearing the soft patter of rain on the roof of the cabin. I grabbed my trousers and coat before slipping out of the room, unlocking the cabin and then quietly making my way over to the caravan, where I knocked on the door. The rain had slowly gotten heavier as I padded across the lawn. I heard the lock click and the door opened a crack, casting a warm slither of light across the garden.

"Lily it's me," I said. She opened the door and let me in, keeping herself hidden until she closed it behind me and locked it. I could see she had closed every curtain and shutter and made the bed. The little radio she always brought with her to play while she slept was tuned to a classical music station. The little space heater was whirring, making the van a welcome experience in contrast to the sudden chill outside. I turned to Lily and gasped. She was wearing the lingerie her mother had scolded her over so angrily those months ago. She stood waiting for my reaction, her eyes wide. Her breasts barely fit in the lilac bra, spilling ample amounts of her pale pink skin over the top, her breasts being lifted by the bra was an incredible sight. It was lace and very revealing. Her nipple was visible through the mesh. Her panties were equally as alluring and see through. Lily twirled, showing me the back of the panties which were disappearing into the crack of her butt. I let out a moan and bit my lip. She looked incredible, like something from a fantasy, and I felt myself stiffen immediately.

"What do you think?" She said, apprehension on her face.

"You look..." I cast around for the words that could describe how she looked.

"Radiant," I settled on.

"No one has ever seen me like this before." The rain started to patter on the roof of the caravan.

"I'm glad I could be the first." I moved towards her and we began to kiss, at first gentle, but soon with a passion that would rival that of lovers forced apart for years. She grabbed at my clothes taking them off item by item in between kissing me until finally I was naked and her hand was clasped around my now monstrous sized, throbbing cock.

She took a step back and I removed her panties, taking great care to stroke her butt as I removed them. She reached behind herself and unclasped her bra, letting it drop to the ground releasing her giant breasts. Her nipples were enormous and almost as hard as my cock. I pushed her onto the bed and climbed on top of her, taking one of her erect nipples in my mouth, sucking as she gasped and moaned.

"I love you," she said suddenly "I always have, since the moment she brought you round for that first dinner."

"I love you too," I said, knowing it to be true. Knowing that I had loved both her and her sister for some time now. The feeling began slowly, but took control like a wildfire that had suddenly been released into the forest.

"Really?" She asked as she guided the enormous head of my cock into her drenched pussy.

"Really," I replied, bringing my lips to hers once more. I slid everything I had as deep as I could go without hurting her. She kissed me with renewed enthusiasm as the rain picked up outside. I moved faster as Lily began to moan surprisingly loud. Her moans masked from the outside world by the sound of the rain now hammering on the roof. I got harder once more, watching the rippling of her giant breasts as I thrusted into her. Her voice, now moaning even louder, was drowned out by the deafening, thundering sound of the rain on the roof.

With each thrust she opened her mouth, but I couldn't hear anything that she was saying, her eyes rolling as I thrust harder and harder. I made love to her, kissing her neck, her breasts, feeling her hands all over me. The rain got yet even louder and now I couldn't hear myself think. I focused on the only thing I knew in that moment, the only goal I had, to make Lily cum. I could see her mouthing the words "I love you" as I felt the build-up. Knowing that I couldn't keep this up much longer as finally she started to shake and quiver, I buried my cock as far as I could put it and released, filling her with my hot seed. I pulled out to shoot some of my hot cum over her breasts, but as I did she released a spray like a fountain and soaked me.

Her eyes suddenly wide in horror.

"I'm sorry," I could see her mouth.

I knew she wouldn't hear me so I lean in and kissed her, moving to her ear and saying as loud as I could without shouting, "Lily, I love you, there is nothing to be sorry about, and I liked it."

She smiled and grabbed a towel, cleaning us both down. The rain did not stop, but eventually I was back in my trousers and coat and we were kissing goodbye at the door like lovers that wouldn't see each other again for a long time, despite the fact that she was sleeping on the same property. I flicked the light out in the caravan and opened the door, stepping into the deluge. Splashing back to the cabin through the puddles now dominating the garden. I took a look over my shoulder to see the caravan door firmly closed and safe from the torrential downpour I made my way back inside and locked the door.

Trotting over to the bedroom, I tiptoed inside to find the light on and Rose awake. She looked at me as I entered, sopping wet and grumpy looking, my hatred of rain plastered across my face. The rain still was incredibly loud in here but less so than in the caravan, and as I towelled myself dry I looked over at the girl who I was sure was still going to be asleep.

"Where did you go?" she asked.

"To the toilet."

"Baby you were gone a long time."

"You know I don't like rain."

She moved towards my now naked body and put the end of my cock in her mouth.

"Have you been fucking Lily?" she asked, taking my cock out of her mouth.

I looked at her but didn't answer.

"This morning you tasted just like this, and then on the beach you tasted like you normally do, and now you taste all sweet again."

I stayed silent, knowing to reply would only provoke an argument.

"Please answer me. You were just having sex with her, weren't you?"

"Yes," I said, not taking my eyes off of her.

"And you had sex with her last night after I went to bed."

"Yes, but..."

"Did you take her virginity?" She interrupted.

"Yes."

"Did she like it?"

"W... what?" I asked, very confused.

"Did you make her first time a good one?"

"Yes, of course I did," I replied sharply.

"Well that's good then." With that she laid down, turned away, and didn't say another word.

"Rose, baby I'm sorry, I won't say I made a mistake or it was stupid, because I didn't make a mistake and it definitely wasn't stupid. I won't invalidate her like that. I enjoyed it and she enjoyed it. I just like her a lot." She didn't reply, but just pushed her bum into my cock as I climbed into bed.

"I love you," I said, stroking her leg.

"I love you too," she replied finally. It was a long time before sleep finally took me, terrified that Rose would tell someone or break up with me.

The following morning arrived with the continuous sound of the rain hammering on the roof, and the sound of laughter in the main pool room. I got up, pulled my dressing gown on and wandered into the main room to find Rose and Lily both playing a game of pool and laughing at something Rose had just said.

"Morning baby," Rose said lightly and moved my way to kiss me on the lips, throwing her arms around me.

"So, we are stuck in here today. My aunt and uncle have driven over to the next town to go help out where some of the buildings have lost power. They left food in the fridge behind the bar and told us to call them if anything happens.

"Damn. Well they were right; when it rains, it rains," I said.

"Yeah, imagine how bad it is when they have one of the named storms," Lily said, peering out of the window.

I went and got dressed before braving the storm to use the bathroom. When I got back, now soaking wet, I found the girls sitting on the bed in the little bedroom playing cards.

"We got bored of pool," Lily told me. "We were terrible."

Rose jumped up to grab some water from the fridge and I quickly planted a kiss on Lily's lips.

"She knows" I said, Lily's eyes widening.

"You told her?"

"She had figured it out."

"Is she mad?"

"I have no idea," I replied, giving her another quick peck on the lips before the door opened and Rose strode back in with 3 bottles of water.

"What are you guys doing," she said, poking her sister in the belly and plonking down onto the bed between us both.

"Just deciding what game to play," Lily said. "Do you both want to play a game?"

"What game?" Rose asked.

"We could play Uno?" Lily bounced up to get the cards, not waiting for a response.

"Sure okay," Rose replied as Lily bounded out of the room and over to the caravan braving the storm.

"Are you okay?" I asked her.

"I'm fine. Honestly, I think I'm okay with it."

"You are okay with it?"

"Only if she's okay with it." There was silence for a moment as we looked at each other.

"You know as well as I do she's a nightmare playing Uno" I said.

"Yeah, but she wants to play it and it's her holiday too."

I laughed. There was no more competitive person than Lily while playing Uno and she had had many arguments about the rules with us over the years.

She made her way back into the room after a few minutes holding her cards and what must have been her PJs, which she changed into out of her wet clothes. They were made up of a tiny almost see-through vest top that didn't cover her belly, and the smallest pair of shorts, with a dressing gown draped over her shoulders.

"We doing PJs?" Rose asked, crossing over to her bag and extracting almost as scandalous pair of small shorts that were more panties than shorts, and a slightly larger vest top. I stood and grabbed my shorts, the only things I usually wore to bed, and my dressing gown. The whole time while stripping and changing with Rose, Lily's eyes were on me, watching my cock swing between my legs as I changed. Rose not unaware of her sister's gaze.

Soon we were all back on the bed playing Uno, where two games in a row Lily Destroyed us mercilessly.

"God you guys are rubbish," she teased, leaning forwards and giving me an uninterrupted view down her ample cleavage.

"You just change the rules to suit yourself" I say, teasing back.

"DO NOT," she spat back jokingly.

"DO TOO!"

"Okay well let's play one more, I know one of us can beat you," Rose said.

"You absolutely cannot." Lily straightened up causing her breasts to sway and jiggle as she did so.

"Wanna bet!?" Rose replied, matching her sister.

"Sure," Lily said. "What are the stakes?"

"If one of us wins, you have to buy us chocolate," Rose replied.

"Nooo, that's weak!" Lily said. "It's got to be something big."

"Like what?" I asked

"Like..." Lily hummed.

Rose looked between us and then said, "if I win, I get to watch."

Lily almost fell off of the bed. "Wh.. what? Watch what?"

"I get to watch my boyfriend cheating on me with you."

"And if I win?" Lily asked

"Well, you get what you want?" Rose asked.

"What do I want?" Lily asked.

"My permission."

"Your permission?"

"Well you want him to be your boyfriend right?"

"You will dump him?"

"No we can both have him, but only if you win."

"Should we maybe talk about this instead of putting this to a game of Uno?" I said incredulously.

"Well what about you!?" they demanded ignoring my question. "What if you win?"

"Well, if I win..." I let the silence pause, if they were both on this, I knew that I could try for what I wanted, "If I win, I want you both, at the same time."

The silence was deafening, it was one thing letting them watch one another having sex, but a threesome with two sisters, that might be asking too much. Lily and Rose looked at one another before nodding.

"Done," they said together.

"You won't win, so that's fine," Rose continued, though I couldn't help notice that her nipples stood erect pitching tents in her top. I turned to look at Lily's whose were the same. She began dealing the cards, and with every round the tension grew. I was down to two cards left, but alas, I had to pick up, four. Lily almost got out then she had to draw, two. Rose was consistently behind but pulled it back, the game was neck and neck between Rose and I.

I had one card left, "Uno!" I shouted and both girls tensed slightly.

"Uno!" Rose shouted, placing her penultimate card down.

It was my turn once more, I couldn't go, I had nothing to place. "Fuck," I said, picking up a card.

"Oh my god!" Lily said, positively quivering as Rose took her turn.

Rose dropped her final card onto the pile, "I win." She triumphantly sat back looking at us both. I looked at Lily who smiled defeated.

"It was a stupid bet anyway," Lily said, looking a little sad.

"So how does this work?" I asked.

"I think you guys just get started, I'll sit here and watch I think," Rose said a bit unsure.

"Are you fine with us kissing or just having sex?" I ask Rose, not wanting to upset her.

"No. Do it properly, enjoy yourselves." She sat back and put a hand down her panties,.

Lily hesitated, watching her sister's hand disappear from sight before pouncing on me. We began to kiss, first slow but more passionately as our hands explored one another's bodies,. We stripped and I took one of her enormous, hard nipples in my mouth and sucked, flicking it with my tongue while she threw her head back and moaned loudly.

Rose had taken her clothes off with us, and was fingering herself; one breast clutched in her other hand,. Her eyes were transfixed as I slid my fingers into her sister's absolutely drenched pussy. We kissed and touched one another as I fingered her, the soaking sounds of her pussy, her moans and the occasional gasps from Rose filling the air. Lily climbed off of me and moved her head down putting the tip of my cock in her mouth tasting my precum before starting to suck, her butt in the air facing her sister.

"Do you like that baby?" Rose said looking at me, her eyes huge with arousal.

"Yes.. so much."

"Should I let you do this more often baby?"

"Yesssss," I moaned" as Rose moved closer and sat next to me, taking my hand and placing it on her soaking pussy, kissing me as she did. Lily came up for air and watched her sister kissing me as she continued to stroke my cock.

"Hey he didn't win" Lily teased.

"Well yeah, but you love him don't you?"

Lily moved up, placing her pussy over the head of my cock, before answering her sister.

"Well yeah, I do. I'm sorry," she replied, looking away.

"I'm okay with it. I'm okay with all of it." Rose's eyes widened and she pressed my hand deeper into her pussy as she watched my cock disappear into her sisters soaking wet vagina. I turned my head and kissed Lily before kissing down her neck, my fingers still in Rose, until I had one of Lily's nipples in my mouth.

Rose moved closer and whispered in my ear, "Fuck her baby."

She gently swept her sister's hair out of her face as I pulled my fingers out of her pussy. Lily grabbed my hand and slid my fingers into her mouth without any hesitation, sucking as she did so. She rode me slowly at first, but grew harder and faster. I moved to suck her other nipple, my tongue flicking the end. I looked to my right to see Rose tentatively touching her sister's heavy breast while continuing to watch us fuck.

"Take me from behind," Lily asked in a breathless voice, filled with so much arousal she was more begging than asking.

She climbed off and bent over, her large breasts squashed under her, her dripping pussy in the air, filling the room with the scent of her arousal. I moved behind her as Rose grasped my cock and guided it into her soaking sister, our lips meeting as I took the girl moaning loudly beneath us from behind, our lips did not break apart as I fucked Lily harder and harder, my full considerable length and girth stretching her pussy, as she moaned even louder into a pillow.

"Cum in her baby" Rose said, seeing the usual signs that I was about to release.

"Yes my love." I kiss her again, thrusting faster.

"Cum in me," Lily begged "Do it, fill me please".

"Breed her. Breed your girlfriend. Breed my sister," Rose said, and like a key unlocking a door, or a dam breaking, I filled her sister with my cum, pumping wave after wave as deep inside as I could reach. With each new wave of cum, she quivered, orgasming, biting the pillow and moaning. I pulled my now cum covered cock out of her, watching the overflow pour out onto the bed. Rose bent down and sucked my cock clean, licking all over my shrinking length.

"You taste so good baby," she said, sucking and licking until I was spotless.

Lily collapsed with us into a pile on the bed and we all lay next to one another, completely naked, breathing heavy, and with my cum deep in Lily's pussy.
