Twin Sister Tricks Bf Into Titjob

Your girlfriend goes out for a run. 10 minutes later, I walk in to come and see her, but you start asking me, her twin step-sister, why I came back so early and changed. I saw the opportunity, you thought I was her, so I lied to your face and in a fraction of a second took her place as your girlfriend. I always envied her; she tells me all about your perfect cock. I'm jealous and wan to find out by myself. I asked you what were you doing and you said "Just relaxing". Well, I can definitely help you relax, you will not expect what's coming your way Smile. I go down on my knees, pull your cock out and start sucking it. You tell me that my mouth feels different, better than usual. I take out my shirt and start titty fucking your cock under my sports bra. You tell me how different and better my tits are feeling today. When I feel like you are close to cumming, I drop the B... and Boom! I'm not your GF babe, I'm your twin step-sister! You beg me to stop, saying she's gonna K... you! No way I'm stopping, I'll continue until you fucking explode between them! (Cumshot between tits under Sports Bra which stays on for a clothed titty fuck until completion). At the end I take off my sports bra to show you my naked tits covered in your cheating cum.
