Sounds so beautiful for you and he to be together when you were horny and so was he for you! If he didn't want to chance making you a mommy, it was better for him to cum outside then shove it back in so you could continue feeling good and connected with him.
When I was in school, I wasted anal because I didn't want to get pregnant, my one black friend wanted to put his cock in my pussy. I wanted it to so I left him put it in there, and he pulled out, he came all over my pussy, and then shoved it back in
