I gave my boyfriend a blow job and swallowed the cum. I'm pretty sure I licked all the extra cum off. Anyway, then we cuddled for a bit (like 20 minutes) and then put our clothes on and made the bed. He then went to the bathroom. When he got back he was soft so I started messing around with him. I think his dick was dry and I don't think he had any precum. Then what happened is I gently rubbed his shaft ( not the head) with my vagina. We stopped after about 30 seconds because I started worrying that this rubbing could get me pregnant. He never entered or anything but could I get pregnant from this? Please help soon.
