Back story, we met at college and we were both dating other people at the time (my ex wasn't a good guy and only did anything sexual three times in two years and his ex had cheated on him for the few months they were together but we didn't know till after)

I was drunk at a house party and went to go find a bed to lay down, I walk in on him with hes ex or on hes own in bed, one of them two can't really remember. But being drunk and pent up i started to kiss him and when his ex saw it happening she stormed off. I was scared at first because he wasn't massive (8-10 inches, not 100% sure) but its the biggest I've had so it felt like I was riding for my life but after a while I started to relax then we got kicked out the next morning and have been together ever since.
