Enjoys it

"Oh god, Dexter." She moans as he keeps thrusting jnsjde of her. "Don't stop. That feels so good."

He starts thrusting harder inside of her, encourged by her moaning his name. Leaning over, he nips at her ear. "Dad must not do this anymore, does he?" He chuckles as she shakes her head. "You still fertile?" He grins as she nods. "How about we make me another brother or sister?"

"We can't. Your dad would kill you." She pants out. He chuckles as she didn't say that she wouldn't want it.

"Then you'll want to make sure you mate with him tonight then if you don't want him to find out." He threatens as his thrusts speed up and he gets close to cuming, feeling his balls tightening up as his knot pushes against her entrance, threatening to tie them together.
