I stop

Hearing the panic in Millie's voice, I stop moving as well, and stay absolutely still, and there I am, laying on top of my step-mom, her legs spread around me, and my cock half way into her pussy.

Our eyes meet, my breathing is very heavy, as her pussy feels incredible, and Millie is breathing heavily as well, but I don't know if it is from our wrestling or if it is from feeling my cock in her pussy.

"I am sorry Millie, it just slipped in." I say.

Millie looks up at me, a stern look in her eyes, and says:

"Matt, take it out."
