Chapter 7

 I start cumming and I don't think I'll ever stop. Lilly keeps stroking and sucking and swallowing and I just keep spewing more and more cum in her mouth. She was right. I'm cumming harder than I would have believed possible. It feels like my whole body is throbbing, as I shoot load after load of cum in her mouth. As hard as she tries, she can't swallow it fast enough. Some of it runs out of her mouth and down around my cock.

I finally stop cumming and fall back on her bed, panting. When Lilly finishes swallowing the last of my cum, she sucks my cock clean and lets it slowly plop out of her mouth, onto my stomach. She glides her tongue down my very sensitive shaft and starts licking around the base of my cock. It takes me a minute to realize she's licking up the cum that overflowed out of her mouth.

 My god! For someone who had never touched a cock before yesterday, she is fucking amazing. She finishes lapping up the cum and glides her body up along mine, until she is lying on top of me. Our eyes meet. "So," she says as she plants kisses on my face. "Did I pass the oral exam? I did a little research on my own. Could you tell?" Her lips are hot and wet. She presses them against mine, I open my mouth and she pushes her hot tongue inside. It tastes funny, but then I've never tasted my cum before.

"I am so hot, Collins," she whispers. Touch me, please."

All pretense of me being Alvin is gone. It is just us. Collins and Lily: brother and step-sister. Tasting the joys of lustful love. I want her to feel as great as she just made me feel. "I'm going to do more than touch you, Lilly. I want to taste you." Remembering my reaction to her talking about sucking my cock, I whisper to her what I'm going to do.

"I'm going to lick you and push my tongue up inside you. I'm going eat your pussy and taste your juices. Unlike guys, they say that girls can have multiple orgasms. We're going to see if that's true." I roll her over onto her back and lie next to her. Leaning up on my elbow and looking down at her beautiful body, I still can't believe all this is happening. My step-sister , who has just given me the world's best blowjob, is now lying there waiting for me to eat her pussy.

Lying down, her tits look like two perfectly rounded little bumps, connected by a white stripe where her swimsuit top covers. Her firm, white mounds are topped with little rosebud nipples that are rock hard right now and remind me of pink pencil erasers, the way they stick out. I trace a circle around her tits with my finger, then bend my head down and suck her left nipple into my mouth. Massaging her tit with my hand, I take the nipple between my teeth, biting gently, as I flick the tip of it with my tongue.

"Mmm. That feels great!" Lilly is running her fingers through my hair and smiling at me.

After a while I switch to her right tit and give it the same treatment. While still nibbling on her nipple, I move my hand down from her breast, across her stomach and into her panties. Combining my fingers through her blonde hair, I feel the heat even before I touch the moisture. I rub my finger up and down her juicy slit. She is soaking wet and my finger easily slips inside her pussy. I start moving my finger in and out, while rubbing my hand against her mound.
