Just cup them lightly, then drag your fingernails across them." I lay my head back on her bed, as she strokes my cock and caresses my balls. "God, Lisa, that feels really good." I watch her face and she seems as mesmerized by my cock as I have been of her pussy.

"If you keep doing that, I'm going to cum," I tell her. "It feels great, but we're not here to learn hand jobs. Keep stroking it like that and playing with my balls, but lean down and start licking the sides like an ice cream cone."

"Like this?" she asks as she begins licking the head of my cock." Just as I'm going to tell her she's doing great, I realize I'm going to cum.

"Lisa, quick! Wrap your lips around the head of my cock." I'm lifting my butt off the bed and pushing my cock up into her mouth, as I say this. "I'm going to cum and you need to catch it in your mouth and swallow it. Hurry!" She wraps her lips around my cock and I instantly begin spewing cum into her mouth. Her eyes get real big, as she looks at me with a questioning look on her face.

"Swallow it!" I yell. "Go on and swallow, but keep your lips around my cock, there's more." And there is, it's been building up since I watched her changing into her swimsuit. She starts swallowing, almost gags, but then keeps sucking on the head of my cock until I'm drained. I lie back on the bed as Lisa's licking the last bits of cum off my cock and from around her lips.

"It tastes funny," she says, smiling. "But I kind of liked getting you off like that. Wow, you were really moving in and out of my mouth when you came. Did I do okay?"

"God, Lisa, you did great," I say, and then realize that I want these lessons to go on for a while, "for your first time, I mean." I look at the clock and see that Mom will be home in about half an hour.

"Look at the time. We'd better stop for today." I'm looking at my beautiful, naked sister, who is still on her knees between my legs, and another thought occurs to me. "How do you feel, Sis? Did sucking my cock make your pussy wet?" I'm starring at her blonde pubic patch, as I ask her this.

"Yeah, it was a real turn on. More than I thought it would be. I didn't want to stop and I'm still pretty hot and wet down there."

"Let me see." I slide down and put my hand between her legs. She moves her knees apart to allow my hand to touch her pussy lips. They are soaking wet and when I run my thumb up and down her slit, she moans, putting her left hand down on the bed to steady herself. She's steamy hot and we only have a few minutes.

"I'm going to help you feel better, Sis," I tell her as I push my middle finger up inside her slippery, wet pussy. I start rubbing circles on her clit with my thumb, which is still wet from her juices.

"Oh god! What are you doing, Jack? That feels incredible."

"This is nothing compared to what we'll do when we have more time. Tony isn't the only one who shouldn't have to jack himself off. You deserve your sexual release as well." I'm not sure she's hearing me because she's moaning so loudly and moving up and down on my hand.

I watch her tits bouncing and remember what she had said about how she liked Tony pinching her nipples. I reach up with my other hand and begin massaging her right tit. Pinching her nipple between my thumb and index finger, I squeeze a little. She starts bouncing faster on my finger and I'm having trouble keeping my thumb on her clit. I push my thumb a little harder against her clit and just move it back and forth really fast, while she rides my finger. I pull on her nipple, pinching it and stretching it out as far as it will go. I can tell she's getting close. I switch to her left tit and do the same thing. I manage to push a second finger up inside her pussy, while she keeps bouncing up and down as hard as she can.

Suddenly, she stops moving and I feel her pussy clamp around my fingers, pulsing in and out. It's like I can feel her heartbeat through her pussy walls. She grabs my hand and holds my thumb still, while she pushes down hard on my soaking wet fingers. I let go of her tit and reach my hand around her back, pulling her down on me. She collapses on my chest with her head on my shoulder and my fingers still in her sopping, wet pussy.

She just lies there, catching her breath. With her naked body stretched across me, I move my hand down to her ass and gave it a gentle squeeze. All my fantasies are coming true. I've played with her tits, finger fucked her pussy and even shot my cum in her mouth. What an afternoon, and I have Tony to thank for it. But I think he'll be the one thanking me before this is over. I look at the clock again and begin pulling my fingers out of her pussy.

"Not yet, Jack. Please leave it there for a little longer," she pleads....!
