Chapter 11

"Yeah, Collins, faster like that. I want you to fuck me faster." My step-sister is now raising up her ass and matching me stroke for stroke. Her hands are gripping my back, pulling me tightly against her. My face is buried in her neck and my arms are under her shoulders. With my hands holding her body from sliding up the bed, I slam my cock harder into her pussy. 

My balls are slapping her ass and she's grinding her clit against me as I plunge deeper and deeper into her hot, virgin hole. "Keep going faster, Collins! Yeah, harder like that. Don't stop, Collins. Don't stop. Yes! Yes! Ohh God! Collins! Collins! Pleeeeeeeezz don't stop!! Ohhh."

 She is clawing at my back and screaming as we keep up the pounding rhythm of our lovemaking. I'm getting close and I'm trying hard to keep up with her, as she arches up and down faster and faster, pushing my cock in and out of her incredibly tight pussy.

"Ohhhhhh, Don't stop, Collins! I'm cumming!" She wraps her arms around me and holds me tightly to her. I pound into her as hard as I can. My balls are slapping against her ass and I can actually hear my cock moving in and out of her slushy, wet pussy. 

When her fiery pussy walls clamp down on my rigid cock, it puts me over the top and the first load of cum, to ever touch her virgin pussy, is squeezed out in spasmodic bursts from my hard, throbbing cock. She bucks and shivers as our orgasms meet each other in a climatic push and she wraps her legs around me, holding me deep inside her.

We are both panting and I can feel her chest rise and fall against mine. I turn my head and kiss her gently on the lips. We stay tensely pushed up against each other, waiting for our orgasms to subside. My cock is fully spent inside her and I can feel her pussy pulsating around it. I relax a little as I lay there on top of her, catching my breath. Neither of us said anything for a long time. 

We just hold on to each other basking in the afterglow of her first time. Lilly is the first to speak. "That was wonderful, Collins!" she says, turning her head to look at me. "It didn't hurt as much as I thought it would. You were so gentle and so loving. And of course, you had gotten me so hot." She's smiling up at me with her head tilted to one side. "So, still think being with your step-sister is weird? Do you think what we're doing is wrong?"

"It isn't weird, Lilly. What's weird is that you're so incredibly sexy; you make me forget about any girl I've ever been with or even fantasized about," I say, kissing her on her lips. "I really love you Lilly, and I don't want to stop what we've started."

 "Neither do I, Collins," she says, squeezing her pussy muscles around my spent cock. "You've made me into a woman today. I want you to keep making me feel like a woman."

"What will be wrong is if we let ourselves get caught," I say, looking at the clock. "Speaking of which, we better get ourselves and your bed cleaned up. We have about another hour before Mom gets home. I think we should take a shower." 

"Together?" she asks, smiling up at me.

"Yes! And then we need to wash your bedding and air out your room. It smells like sex in here. Tomorrow we need to remember to pull back the covers and fuck on the sheets instead of the bedspread."

"Tomorrow? So you're already planning ahead, huh? What have you got in mind for tomorrow? Are you going to assign more homework for tonight?" Lilly asks, laughing.

"Yes. Tomorrow, the day after, and the day after that, and the day after that," I answer, kissing all over her face as I speak. "And since you're such a good student and you got extra credit for your additional research last night, I want you to do some more research tonight. I want you to look up all the different sexual positions you can find and make a list of the ones you want to try," I tell her, moving my mouth to her neck. 

"I already know of two that I want to try. I really want to do it with you on top, so I can watch your sexy tits bouncing up and down, and play with your nipples while we fuck. And you have such an incredibly beautiful ass, Lilly, that I can't wait to fuck you from behind and watch the curves of your ass, while my cock slides in and out of your pussy.”
