I’m a college sophomore and live with my father, his girlfriend Elise and Elise’s 18-year-old daughter Donna.

The house is a split-level, with Donna’s and my rooms on the lower level. One night I was in my room studying late, and on my way to the bathroom I noticed Donna’s door open. In the faint light I saw her asleep, the covers down to her knees. As her nightshirt had worked up, her pink nylon panties were visible. I snuck in the room for a better view. I could make out her pubic mound pushing at the panties! I stood staring awhile, watching her nubile form heave as she breathed.

When I heard the floor upstairs creak, I knew it had to be Donna’s mother coming to check on us. I beat a retreat to my room and pretended to be studying just as Elise came down the stairs. After she’d gone back up I waited a few minutes, then went back to Donna’s room. I stood beside her bed looking down at her. She’d shifted positions but was still on her back, with one arm over her head and the other flopping over the bedside. Her legs were spread, with her left knee bent to one side and extending over the bed.

With my cock hardening and my heart thumping, I bent down for a closer look at her breasts, surprised at how big they looked in her nightshirt. I was shocked out of my lusty stupor by Donna saying, “Do you like them?”

My brain scrambled for an answer, with my cock wilting. At last Donna propped herself up and said, “Don’t worry, no one will know.”

I got excited — all over! I pulled her nightshirt up over her breasts and, when she didn’t protest, removed it. My eyes drifted down her flat belly to the vee of her pubic area. I slipped my fingers under the waistband of her panties. She raised her hips and I pulled them off.

I noticed Donna’s lower lip trembling, signaling her arousal and nervousness. I guided her hand to my cock and placed my hand on her breasts. Her nipples hardened even before my lips touched them. She gasped as I slid a hand between her soft thighs. She spread them, allowing more room for my hand. Her pussy was warm and moist, and my fingers slipped in her easily, causing another gasp.

The more I worked at her pussy, the faster she stroked my cock, and soon I was ready to explode. But I didn’t let myself come. I stopped her hand and stood back for several minutes till the urge to come passed.

Donna was sitting on the edge of her bed with her feet on the floor. I stood in front of her and ran my hands through her long hair, then stepped closer, bringing my cock to her mouth. She opened it and my cockhead entered, and she began to suck. I fed her more and soon was pumping in and out of her mouth. Again I built quickly toward climax, and this time couldn’t stop. I shot several spurts down her throat. She didn’t bat an eyelash, but just kept working my cock like a pro.

After she licked the excess come from her chin, she giggled and said, “That was awesome!” I agreed. I laid on the bed by her, and while we caught our breath, we explored each other. After 20 minutes I got hard again and asked if she was ready. She nodded. I got on top of her between her spread legs and assured her I’d be as gentle as possible. I rubbed my cockhead a few times over her vaginal lips, then began to push in slowly.

She held her breath. As I made contact with her hymen, I said, “Wow, you really are a virgin.” She nodded. “Here goes,” I said, and put my hand over her mouth so any yelps wouldn’t wake her mother. Good thing too, as when I penetrated her, she let out a howl I’m sure would have woke Elise. I let her calm down and wiped a tear or two away, then proceeded slowly. Her velvety warmth was beyond description, and her clutching vagina drove me half mad.

I asked if she was okay; between gasps she nodded. I picked up my pace and all too soon felt another climax building. Knowing I was going to come before her, I just shot in her clutching pussy. I pulled out with a wet sound, and she lay panting.

When I caught my breath, I went and got Donna a tissue to clean up with. I kissed her a few times and said, “Thank you,” and she said the same to me. I went back to my room feeling incredibly pleased and slept well the rest of the night.

Donna and I get together almost every day now and our parents don’t suspect a thing, though Elise commented recently about it being odd that good-looking kids like us had no boyfriends or girlfriends. Donna and I looked at each other and said at once: “We’re not ready for that yet.”
