I regularly fuck my friends girlfriend.

It started with her charing on him when we were all drunk and he was blacked out. Next morning she confessed and it turned out he was into it.

He is on some meds and can barely get one up and if he doesn't jerk off for days and manages to get hard he cums after a few seconds.
They talked about this option before but decided that if she fucks someone else it should be a stranger.

I love size difference

It matters
