Input: Text: so my girlfriend is sleeping over at my house for the weekend and normally when we come over at one of our houses we do some sexual things, we haven't had sex yet (she isn't ready and we need condoms) and it's all consensual. so like an hour before i type this, we were doing sexual stuff, and all of a sudden, my mom opens the door and after a brief stare she said "i just wanted to say that the pistolets are ready" and casually walked off. i was frustrated and she said she heard someone come down the stairs but wasn't sure. she could've told me but there isn't much i can do about it...

after that, i just got upstairs and just casually chatted with my mom, she hasn't lectured me about it and because we still had covers on, me and her might get off of it if we lie that we were just innocently fooling around. she has caught me with jerking off in the past and said that only rapists jerk off while that obviously isn't the case. i am fucking afraid that she is afraid or "predict" that i will rape my girlfriend (or even raped my girlfriend, if that's the case, how the fuck can i say that she wanted it too?) while i'd rather hurt myself than rape.

if there's an update, i'll make a tifu update.

TIFU by getting caught dry humping.
