Am I pregnant? He secretly fucks without condom

What a bastard !!!! It all started quite harmlessly: Because my old roommate, the snotty business administration student, is moving out, I'm looking for a new one. The first prospect looks really nice and makes a totally personable impression. Well, somehow one thing leads to another and we fuck on my couch :-) So far everything is good, but that this devious bastard actually manages to pull the rubber off unnoticed and just inject it into me ... And laughs at me stupidly because I forgot the pill ... OMG, if he got me pregnant now ...
