Wanting My Stepsister

She moans into the pillow and raises her hips, asking me to take her harder. I grip her ass and thrust deep, the way she likes it. She loves when I talk filthy to her, and my words, just as much as my cock, are getting her off.

We found out she was pregnant a month ago, but we wanted to wait until Christmas morning to tell Mom and Dad. They are going to be so excited. Grandbabies have been all they’ve talked about lately, even though we are young. I think they knew that we don’t want to wait, and I’m more than happy to do my part in the baby-making process.

Libby is horny all the time, so getting her pregnant was the easy part. It’s hard for us to go more than a few hours without me being inside her. Our connection is so intense that she travels around town with me for work, and we have to pull off in the woods to fuck in the car if it’s been too long. She’s insatiable, and I love trying to keep up with her needs.

I feel her orgasm hit her as her clenches start, and she tries to hold back her screams of pleasure. She usually goes off two or three times when we fuck, but I know she’s trying to hold back. I laugh and lean down next to her ear.

“Oh no, baby girl. I want more.” Reaching under her belly, I slide my hand down to her soaked pussy and play with her clit. “Remember who your daddy is now. You do what I say.”

Sitting up, I start to fuck her hard. So hard that the headboard beats against the wall. She leans back and shushes me, but I just smile and wink at her. There’s never going to be anything that stops me from making her feel good. And as much as she likes to protest, the thought of getting caught makes her hot. I know this because at that moment, she cums again, and this time I follow her.
