so i was fucking around and telling my friends stories and i told them the one that i posted the other day. so i posted it, and i was chilling out with my girlfriend the other day and she started pleasing jack and the beanstalk. when she does this we talk about our days because it lets us relax. while she was doing this i maybe let it slip that i posted that she didn't seem mad but speed up and got a better grip. i asked her to stop but she started kissing i distract me. seconds later i felt a lot of pain. she told me that she was upset and left. i didn't finish and i just sat there in the most pain i've ever been in. i toke a cold shower to get rid of my hard on. when i exited it was gone but there was a red handprint on my dick... i was basically crying by then. it's been almost 24 hours and the mark is still there she apologized and everything is good but it hurts like a motherfucker.
