Keeping an Eye on Things Pt. 06

My knees were trembling, my heart pounding, my skin tingling all over. My balls felt a satisfied emptiness I had never felt before and a sense of fulfillment enveloped me as I stood there, my dick buried to the hilt inside my sister.

Caitlin moaned as I pulled out of her. "That was nice," she said over her shoulder, "Now for the next bit." She quickly turned facing me, then dropped to her knees and took hold of my half-deflated tool. Lifting it, she swallowed it. I mean she took it all in. I could feel the warmth of her mouth, her lips. Her tongue, as she bobbed her head backwards, touching the glans, then sliding in again.

As I got harder, she couldn't quite get as much in, but the fact she was sucking on my dick, covered with her own juices and a layer of my cum, I don't think I can handle this. Do nothing, I told myself, let her do what she wants. I didn't grab her head; I just stood there dumbfounded, but it was very erotic.

After a few more bobs, she took it out of her mouth. "Yeah, not bad, bro," she said, "Now, let's give them a couple more minutes, and you'll be able to fuck them both." She stood and opened the shower stall door, taking my hand.

I shook my head, thinking after that adventure, I couldn't please anyone with the way my dick was deflating again. "I'm not so sure," I said.

"You'll be fine," she replied, reaching for a towel. "And if you start to flag, one of us will start licking your asshole; that'll get you going again."

All this was too much, but I couldn't show Caitlin that. I started drying myself, making sure I really was dry around the dick. "Did you cum?" I asked innocently.

"No, but it doesn't matter," Caitlin replied nonchalantly. "Never cum with a dick. Look, don't get all paranoid about it; the truth is I like a dick in me, but I've never cum with that alone. Not a lot of women do, I think. The feeling I get is just- well- very, very nice, but it takes a tongue or fingers to make me cum. Dick doesn't get to play with my clit, and I gotta be flicking my bean when I'm with a guy to cum when fucking. Lot of women are like that, so don't worry about it, you got a tongue and fingers. You're gonna have to use them now."

All the porn movies I've seen the girls must have been acting out, well duh! I am so fucking stupid sometimes. They're movies, acting, likely the only real shot is the money shot. That had me worried. Oh I've seen lots of lesbian porn but trying to get an idea of what they are actually doing, that's not easy.

"Caitlin, wait!" What do I say next? "I-I-I've never-"

She looked at me. "You've never gone down on a girl?" She was amazed. I shook my head. "Then there's no time like right now to learn."

She laid her towel on the floor of the bathroom and sat on it. She spread her legs. "Come on, eat me."

"What? I just cum in you!"

"So what, it's like chewing your nails, no big deal, besides, if you want to fool both Milly and Luna, you're gonna need the practice. Won't take long, but I promise, it won't be bad. Come on, man up!"

I could see her point but a cream pie? My own cream pie? I was somewhat hesitant, but Caitlin insisted, and eventually told me she would tell them everything if I didn't.

Call me coward, I didn't want to be humiliated like that, so I bowed to the inevitable. I got on my knees in front of Caitlin's pussy. I started to bend my head in to touch her pussy but she told me to stop.

"First, don't just go down on a woman, make her want it. If you're lying in bed, kiss her breasts, her torso, little nibbles, gently over her belly and make your way down slowly. Her, my, legs are already spread, so start at the feet and kiss your way up the inside of her thighs. Try it."

I did. Not too quickly, but I used my tongue on the soft tissues of her thighs. "That's good," she commented, "Very sexy, but use both thighs, going higher every time you change."

I followed her advice and did as she said. I was about to reach the goal, but she stopped me again. "Now, look at her pussy. What can you see? Describe it."

"It's leaking a little white goo, me I suppose. There is a lot of pink tissue surrounded by soft and swollen lips. These are the labia." Caitin nodded. "It's all glistening-"

"Good, that's what you're looking for; she's aroused, excited, stimulated and makes it easier to get her wound up even more. Go on."

"The lips are capped by a little swollen tissue, the clit?"

"Yes, it is. I want you to lean in and sip it between your lips, and no teeth."

I did that and she moaned, "Yeah, just like that." I kept doing the same thing, suckling on her clit. "Now, lift your chin and get your finger inside me, without letting go of my clit."

I did that and found my finger slid in easily. Well, it would. "Pump it slowly," she said. "Some like this hard, but others prefer it slow and gently. Luna likes this a little rough, but Milly doesn't. Oh, and make sure if you're fingering a woman, your nails don't have any sharp edges."

I fingered her gently and felt the slightly slimy inside of her fuck hole, then she said, "Now a second finger. But be careful; if she's wet enough you'll get in fairly easily, but if she's not, it could hurt her."

Again I followed her instructions and pumped two fingers in and out of her. The noises she was making between instructions were enough to make me think she really was getting off on this. The aroma of her sex filled my nostrils; the taste of her clit was different, but not unpleasant. It was, mostly, Caitlin, then there was the juices producing their own aroma.

"Poke my clit with your tongue." I did that. "Yes, that's very good. Now pull your fingers out and run your tongue down my pussy. All the way down, then back up again."

I did as she told me, and again, I was struck with the differences between what I was doing and what I had been watching on my computer.

"Oh yeah, that's very nice, keep that up!" And a bit later, "Oh yeah, now go back to sucking and tongueing my clit. Gotta get the timing right, not too long on one thing, then change it up." So I did that, and after a couple of minutes, went back to tongueing her whole pussy.

"OOOHHH yeah! That's good! Keep that up and you'll have me cumming real soon!"

So I did. I was surprised at just how quickly I managed to get her to cum. Her orgasm announced itself with a huge moan, and her gripping my head with her hands and thighs, tightly so I wasn't going anywhere. At this time I was laid out flat and my dick was really hard, which was surprising on the tiled floor. Guess she was right, young and fit get hard again quickly, but can I sustain it.

After a few moments, Caitlin released me, and sighed. "That was pretty good for your first time."

"And didn't taste too bad either," I said, kissing her mons again.

"You think you recovered enough?"

"Yeah, feels like it." I sat up and looked at Caitlin, still lying there, legs spread, tits fully open to my view, fuck, she is beautiful, even if she is my sister.

"Okay, I'll take care of Luna and you can fix up Milly," Caitlin said. "Then we'll swap."

"Luna staying the night?"

"She will be now, I would think," Caitlin smiled, "But don't worry about it, she's a good fuck, either way. Now you know how, you think you can make them both cum?"

"Yeah, really appreciate the help." I did, really. If this is going to make me a better lover, then I really will be thankful to Caitlin. I stood and held out my hand.

"Good," she said as she took my hand and stood, "Now let's go get laid!"
