After a night of drinking my girlfriend and I decided to play a game that involved various questions we chose to ask each other. I ended up asking her about a guy she had mentioned a couple times before and found out that for the few months she was messing around with him she never actually had sex with him. I asked her what they would usually end up doing and she told me she would stick his cock after he fingered her a bit.

The thought of some guy essentially picking her up just to get his cock sucked turned me on so much. I'm pretty sure she saw me getting hard because I saw her glance down and she continued on a little more than she normally would
