I couldn't fucking believe this. I really couldn't. But I didn't want to come across as a chicken.So I stood up, pulled off my shirt, and pulled off m... shorts. And stood there in my blue bikini underwear. With a big fucking hardon inside my underwear.My stepdaughter just sat there on the couch looking. Christina sat there on the couch looking. And then my stepdaughter spoke."Can I see it?" she said.I was speechless. Stunned. And I had no idea what the fuck to do. When Christina spoke."Yeah. I. Mother had taught us that Longshot’s climate mimiced that of our target planet, at least to the best that Ship understood it.

She settled on top of my erection sliding it in and out of her hot wet pussy. Then I was doing her doggie style, she moaned, groaned and screamed begging me for cum. Finally I tossed her on her back and deep drilled for thirty minutes and then came in her in a climax that rocked us both. We continued to make love all through the following.
