Fuck! Did he get me pregnant?

I still can't believe it! It all started so harmlessly... I invited a good boyfriend to my house to have a bit of fun, I told him beforehand that I wasn't currently taking the pill and therefore he wasn't allowed to squirt. I also told him several times during that time that he shouldn't squirt because otherwise I would get pregnant. I blew his cock nicely, we also had really hot sex in doggy and missionary position... so it was planned that he would squirt on my ass after the sex... BUT what does he do? Just squirts it in me!!! Even though I'm not on the pill... what a bummer! Am I pregnant now?
