Wet on top, scared

My boyfriend and I were making out last Saturday. We’re both pretty conservative and want to keep ourselves for marriage so we’ve never gotten too scandalous. I was sitting on him and I know I was really turned on and wet. He was hard under me and every part of my is scared that, in some magical world, that he precame and I’ll end up preggo. He had his underwear and khaki shorts on and I had panties and these thinner lightweight shorts on. I was wet through my panties and into my shorts.
