Usless boyfriend.....

My boyfriend has a hard time finishing from a b******. I tell him it's ok, but really I love the feeling of c** down my throat from giving head. Its like the end of me doing a great job. So last night I said s**** it and found my ex bf. I have inly sucked him off once and never told my bf. But after having that bog load down my throat, I think I'll definitely do it again. Feel a little guilty though...
