[MF][cheating][cuckold] my girlfriend and someone elses cock after a night out

In university me and my gf at the time we’re long distance, but I saw her pretty much every weekend. One Friday night while I was getting ready to get some sleep for an early train, she was getting ready for a night out. She sent me a photo of what she was going to wear – short leather skirt, and a half length button up shirt that left her stomach visible, with too many buttons open for my liking as she wasn’t wearing a bra.

I told her that she looked incredible but I wasn’t really comfortable with her going out like that on her own. Her response? “Don’t worry, I’ve got one of my guy friends looking after me”.

I knew for a fact that all her male friends wanted to fuck her, but trusted that she’d never do anything so after a short phonecall I told her to have a good night.

The next morning I check my phone, on her Snapchat story is a few videos of her partying, normal stuff, and then the last one is of her filming a shot get poured into her stomach which her guy friend licks off.
