My girlfriend watches as I get dominated and fucked by a dominant top

So, I've been hooking up with this total alpha top who really knows how to take charge in the bedroom. Things have been getting wilder and wilder, and now he's even dominating me when I'm over at my girlfriend's place. Her and I have this unspoken agreement where she doesn't mind me getting down and dirty with other guys, and she even gets a kick out of watching. This time, things took a turn when he came over and started giving me the full dom treatment, all while my girl was there, just chilling on the couch. She watched as he took me to town, pounding me like I was his personal plaything. The whole thing was wild and kinky, but damn, it was hot. I could feel her eyes on us, almost like she was joining in on the action. Afterwards, we all laughed it off like nothing happened, but deep down, I knew she was into it.
