Busted! WG roommate's boyfriend fucked!

My flatmate invited her new boyfriend. She wanted to introduce me to her new boyfriend, who is supposed to be so incredibly faithful. Apparently he's supposed to be the perfect man for her... she's been raving about him for weeks... I thought: Okay, I'll see what kind of guy he is... My flatmate wanted to get something in the basement and disappeared for a short moment... me alone with her dream boy... that was probably not such a good idea grin... To seduce him I slipped into my bright pink fishnet dress... he was totally thrilled... I asked him to take a few photos of me... after a few shots, a mega boner appeared under the bathrobe... I couldn't help but suck his big cock... after that I rode his cock with my tight pussy and fucked him until the cream squirted! I hope my roommate didn't stand behind the door and see that... I'm not sure...!
