She Looked Just Like His Sister

When Penny and Dave first started dating, she looked so much like his sister Annabel that his friends kept winding him up about it. "You sure she's not Annie's long lost twin sister?" one of them had said the first time he met her.

Dave was twenty-four, and Penny was twenty-three when they got together. They fell in love quickly. She moved in after a year, and they got married the following summer. They decided the time was right to have a baby and so she came off the pill.

Annabel was a year younger than Dave and had been living with Jerry for a year. Their relationship was steady enough, but neither of them wanted kids yet and there was no talk of marriage.

The four of them had rented an old cottage in Devon for a long weekend away from London. It was basic: wood-fire heating, two bedrooms, and a single bathroom upstairs with just a bath and no shower. They arrived on Friday afternoon. The boys brought in the chopped wood for the fire, then they all started drinking before dinner. Conversation flowed easily over dinner. Dave and Penny looked at each other then he turned to Annabel and Jerry and said, "So we have decided we are trying for a baby now."

Jerry lifted his glass and said, "That's great, try not to keep us up all night eh?" Annabel punched his arm, but she was laughing with him. After the meal they switched to port. By nine both men were asleep in the lounge, heads tipped back as the fire burned next to them.

The girls shook their heads and left them to it. Dave woke an hour later. He saw Jerry was still out cold across the room, and quietly went up the stairs. The bathroom door was ajar. He could see her bent over the bath, about to start washing her hair. Her night shirt had ridden up. Her pussy was peeking out between her thighs, freshly shaved.

Dave smiled. He had been dropping hints all week about how much he'd love it if she shaved before the trip. He stripped off and stepped in behind her, sliding his hands under the shirt to cup her breasts. They felt heavier in that position. She moaned and turned the water off as he rolled and pinched her nipples.

His cock was already pressed against her wet pussy lips. He took one hand off a nipple, reached down, and guided himself into her. She pushed back to meet him, and he felt his balls settle against her clit. He started thrusting, putting his hand back on her nipple and tugging them both as he drove in and out of her wet pussy. He stared as her large inner lips dragged on his shaft and noticed that she had slid a hand between her legs and started rubbing her clit. She had always been too shy to let him watch her touch herself. He congratulated himself on getting her that turned on that she didn't care that he could watch her touching her pussy.

They both knew how thin the walls were. He felt her shuddering as she came with her fist stuffed in her mouth to muffle the sound. He gave a low, strained whisper, "Ah fuck yes!" and started to come too. He had been saving his cum for the weekend and with eight heavy spurts deep in her pussy, he was hopeful they had just conceived their child. When he pulled out, she felt the cum leak out of her onto the tops of her legs and she turned around smiling.

"So you finally gave in on going bare for the weekend, Jerry? I hope you got me some Plan B?"

The smile and the words died in her mouth when she saw his face. It wasn't Jerry. Her brother had just pumped a huge load of cum into her unprotected pussy. She could feel it moving deep inside her.

"Fuck, Annie," he said, "I thought you were Penny. We're trying for a baby."

Annabel stared at him. "I know you two are, you fucking told us that at dinner, Dave. Jerry and I are most definitely not trying to get me fucking pregnant. I track my cycle on an app, Dave. You picked about the worst day you could have to fuck me. Oh, this is so fucked. Fuck. We're here for three days. How do I explain to Jerry that I suddenly need to drive into town for Plan B? There aren't even any shops near this fucking house."

"Please don't be so loud," he said quickly. "Penny and Jerry will kill me if they find out about this."

She put a finger in her pussy and pulled it out covered in his cum. "Fucking hell, Dave. Just how much spunk did you shoot into your little sister's unprotected pussy?" She didn't sound angry. She sounded turned on and she sucked her finger into her mouth and then licked it clean.

She dropped to her knees, and took his soft cock into her mouth, sucking him clean of his cum and her own juices. He was hard by the time she pulled her mouth off him. She stood up, wiping her mouth with the back of her hand.

"Penny's waiting for you in the bedroom in her negligee. I couldn't let you go in there smelling of my pussy. Now go fuck her and make your baby -- or should I say your other baby?" She laughed at his worried look, then added, "Go downstairs first. She knows I'm in here. She needs to think she just heard Jerry fucking me, rather than you. Now go!"

He dressed and slipped downstairs as quietly as he could and Annabel turned the water back on.

Jerry was still asleep by the fire. Dave waited five minutes, then climbed the stairs more heavily.

Penny was lying on the bed in a short negligee, just as Annie had said she would be. He stripped off and crawled between her legs, kissing the insides of her thighs. He pulled the crotch of the negligee aside. Her blonde bush was as full as ever. He ignored the hair and licked between her lips. Up close he could see how different her pussy looked from Annie's.

He pushed his tongue in and tasted her juices, then licked up to her clit a few times. Penny squirmed on his tongue, then pushed him onto his back. "I want to taste you now."

She licked from his balls up to the tip, then pulled off and looked at him.

"I know that taste. You dirty boy. You just fucked Annie, didn't you?"

He started to apologise. She put a finger over his mouth.

"Don't you want to know how I know that taste?"

He nodded.

"I knew her long before I met you. We tried things together. Also, I was pretty sure I could hear your voice after you guys both came. Fuck, this is such a turn-on. You need to be careful, though. Jerry gets jealous. Anyway, you better not try to fuck her again, dirty boy. You are supposed to be saving all your spunk to shoot into me and make our baby."

She climbed over him and sank down onto his hard cock, slowly and going at her pace rather than his. He reached up and rubbed and twisted her nipples until she came, pulling him over the edge with her. He stayed deep in her pussy as he came again.

"Ah fuck, Dave, that feels so good. Your cock is so hard. Just there. Just there. Ah yes, fuck me, fuck me. Make me pregnant. Give me all that lovely warm spunk. Ah yes! Yes! Yes!"

She rolled off him and they both fell asleep.

When he woke up, he was alone and Penny was already downstairs. He could hear the others talking. He dressed and joined them. Jerry looked hungover, but the two women showed no sign of the drinking or the other night activities as they made breakfast. They all ate, then went for a walk through the fields. When they got back, they put the fire and television on and found a series to watch. The room was soon warm and within minutes Jerry's head tipped back and he started to snore quietly. Penny dozed off as well.

Annabel caught Dave's eye and raised her eyebrows toward the door. She stood and walked into the kitchen. He followed. There was a serving hatch through to the lounge. She bent over the counter, looking through it. She could see the back of Jerry's head and Penny asleep on the other sofa. She flipped her skirt up at the back. She wasn't wearing knickers. She turned her head and mouthed, "Fuck me bro."

It was madness. Either of their partners could wake at any moment, but he couldn't resist her. He took his cock out and rubbed it between her pussy lips. They were already wet with her juices. He rubbed on her clit a few times, enjoying her trying to stifle a moan each time. Eventually he pushed slowly into her very wet pussy, fully aware this time of exactly who he was fucking.

She reached under herself and rubbed her clit while his hands went under her shirt to pull and twist her nipples. She let out an "Ah fuck!" then bit her fist as she came. She clearly wasn't quiet enough.

Jerry stirred and mumbled, "Huh. You say something Annie?"

Dave froze with his cock still deep in his sister's pussy.

Penny also heard her and she stood up from the sofa and walked over to Jerry. She dropped in front of him, saying, "She's not here, but I have always wanted to taste your cock, Jerry." She reached into his tracksuit bottoms and pulled out his cock. He didn't try to stop her. She started to suck him and was soon taking him deep. Her eyes kept looking past him at Annabel, though.

Dave started fucking Annabel again in time with Penny's sucking of Jerry. Jerry came first with a loud, "Ah fuck, take all my spunk you fucking bitch. Yes!" Penny swallowed, ignoring his insult and still staring at Annabel behind him.

Dave managed to be quiet as he flooded Annabel's pussy a few seconds later. He pulled out and watched his cum start to slip out of her pussy.

Jerry had just got his trousers done up when Annabel walked past the door on her way upstairs to clean up. Penny followed. Ten minutes later she came back down, walked straight over to Dave, and whispered, "You owe me for that distraction blowjob and because I just licked a ton of cum out of your sister, you dirty boy! Fuck that Jerry is a twat. He has no idea how close I came to biting his dick when he called me a bitch!"

The rest of the day was quiet. Both men stayed off the alcohol and dinner was tame as a result. They all went to bed early. Through the wall Dave and Penny could hear Annabel trying to persuade Jerry to fuck her without a condom.

"Just this once, I want to feel your cock bare inside me," she said. "Please, Jerry. We can get Plan-B when we get back?"

"No," Jerry answered. "No fucking way. You and me aren't stable enough to even think about having a baby. Plan-B isn't 100% you know? No chance!"

Holding back tears, she replied, "Fine. Your unstable girlfriend is sleeping downstairs then, you utter twat!"

They heard her go down the stairs.

Half an hour later Jerry was snoring. They heard Annabel come back upstairs. She opened their door.

"It's fucking freezing down there! The fire has gone out," she said. "Can I sleep with you two? I am too fucked off with Jerry to sleep next to him."

She didn't wait for an answer. She stripped naked and climbed into the bed next to Penny. Both Penny and Dave were already naked under the covers.

Dave shifted slightly. "Okay, Annie. We really should just sleep, though. Okay?"

Annabel said nothing, but she turned and kissed Penny on the mouth, pushing her tongue inside against Penny's. She pulled back and the three of them drifted off.

He was woken in the middle of the night to the bed shifting and then he heard the soft moans as Annabel and Penny licked each other in a sixty-nine. The corridor lights were on and he could see Penny was on the bottom with Annabel straddling her face.

He knew he really shouldn't, but he moved behind Annabel without a word and pushed his cock into her pussy once again. She was wet already from Penny's licking and he could feel Penny's tongue on his balls. When he was in balls deep, he started to thrust and Penny shifted to licking his shaft every time he slid in and out.

When he felt himself getting close, he pulled back and he came, absolutely covering Annabel's open pussy with his cum. Penny swallowed what dropped down into her mouth. When she went to lick his cum off Annabel's pussy, Annabel's fingers got there first. She scooped as much of his cum as she could onto her fingers and pushed them deep into her pussy.

Penny chuckled and said, "Dirty boy. That spunk should be in my pussy, not your little sister's!"

In the morning he woke to a mouth sucking his cock. It was Annabel. The door to the bedroom was open and they could hear Penny chatting to Jerry downstairs.

Annabel looked up at him and said, "Oh good, you're awake. I need fucking big brother!" She threw her night dress off and fully naked, swung her legs over him. She slowly lowered her pussy onto his cock and paused as she felt him fully inside her. She took his hands and put them on her boobs. He leaned up to suck a nipple and she pulled back shaking her head. She put a hand down to her pussy and coated her fingers with her pussy juice, then covered her nipples with them before pulling his head to her boobs. He started licking her nipples again, this time with the taste of her juices.

She rode him hard and he pushed back up into her as well. She used her finger on her clit to ensure she came before he did, "Ah fuck Dave. That feels too good. Fill your sister's cunt with all that lovely spunk. Ah yes!" She pushed down fully and he sprayed her cervix with her morning dose of his cum.

Both realised it had gone very quiet downstairs. They heard Jerry say, "Did you hear that Penny?"

Followed by Penny saying, "No, but get over here Jerry. I need to taste your cock again. Hurry up and let me swallow your cum before they come downstairs."

Annabel dressed and went downstairs. She paused on the stairs to watch Penny sucking Jerry's cock. She heard Jerry say, "Ah take it. Take all my cum. You fucking slut!"

Once Penny had swallowed, Annie walked noisily down the stairs. They were both dressed when she walked in and Annabel walked up to Penny, kissed her on the lips and whispered, "Thanks Penny. Sorry he is such a cunt. I owe you. That was above and beyond!"

Annabel stepped back and said, "Jerry, let's go for a walk outside. We need to talk."

Dave could hear the sound of Annabel and Jerry talking outside his window. She was ending it which shocked him. He had known she was enjoying the sex with Penny and him, but he had never imagined she would actually leave Jerry. He went into the bathroom to have a wash.

By the time he came out, Jerry had left. Penny and Annabel were sitting in the lounge with the fire going. Annabel looked worried.

Penny looked up as he walked in. "So Jerry just left with the car and there are no taxis around here on Sundays. It doesn't look like she can get Plan B in time for it to work, Dave. Also, I really think Annie should move in with us for a while since she is obviously moving out of Jerry's apartment."

Dave smiled as he thought about Annabel, Penny and him in their one-bedroom flat.

Annabel smiled at him and added, "and the good news is my app says I won't be fertile from tomorrow morning - not that you seem to care big brother!" She lifted her night shirt, put a finger in her pussy, licked his cum off it and winked at him.

Their apartment wasn't really built for three, but the bed was big enough. In theory, Annabel slept on the sofa but in practice, she never did.

Two weeks later, Annabel missed her period. A quick test confirmed what they expected. Penny's period arrived on schedule despite the multiple loads of cum that Dave had spurted into her after that hectic weekend.

They sat at the table that evening and worked out their story. It was Jerry's baby. The relationship was already over and Annabel would never tell him. Once the baby was born, Dave and Penny would adopt and become parents. Auntie Annie would stay to help. No one outside the three of them needed to know the rest of the story.

Annabel stood, bent over the table and flipped up her skirt saying, "We should celebrate bro." She wasn't wearing knickers. Dave dropped his trousers and rubbed his cock up and down her pussy lips. He stared into Penny's eyes as he sank into his sister, then started to thrust. Penny reached down to pull at Annabel's nipples. Annabel rubbed her clit and when she came, Dave came with her.

He pulled his cock out of her dripping pussy.

Penny put two fingers into Annabel's pussy, then pulled them out and pushed the mixture of his cum and her juices into her own. She did it three times, then rubbed her clit until she came while she watched Annabel licking her own brother's cock clean.
