You've always found your housemate abit strange... you feel like she's quite inappropriate around you at times and dresses quite provocatively. You think she does this on purpose to annoy your Girlfriend. You're in bed with your Girlfriend one night and wake up to your housemate at the end of your bed stroking your cock through the duvet. Luckily your Girlfriend is still slumbering. Fuck she looks hot; she strips all the way down to her lingerie for you and begs to have a feel of that cock that she can feel poking up out of the duvet. You're reluctant at first, you love your Girlfriend and can never imagine breaking her heart and cheating on her. But your slutty housemate is very convincing, and practically begs you to let her have a suck on that cock. She says your Girlfriends an ugly boring cunt, and that you could do so much better than her. You give in to temptation and your housemate rides that cheating cock with your Girlfriend right next to you. You can't tell what it was that made you blow your cheating load inside of her, how hot she is, how great she is in bed or the fact that you did all of this with your Girlfriend lying right next to you... the riskiness is so fucking hot.
