Finally both of us are approaching the big one. Tatjana dropped on her shoulders and while pressing her tits in the sheets, she starts fingering her p...ssy. I speed up my thrusts and finally slam in and out of her asshole with all my strength."Yes, yes, yes,... [something Czech] aaaaaaaaaaaahhhh!" and her ass totally clamps down on my cock, which was just buried all the way inside.This squeeze also triggers my orgasm and almost painfully violent my balls contract and pump out their payload in. I think her pussy and her orgasms betrayed her too gave her to me; women like forceful men. I kissed K with passion and agreed to her plan. K telephoned Marg and made the arrangements so Marj would come over for the night and I then telephoned my buddy Jason.ìHi Jason itís me whatís up... (Jason) nothing much dude whatís with you... well Jason it occurred to me that you might still want to fuck your bitch sister Marg... (Jason)Fuck her man I want to eat and ream that. I thrust a few times more, then started to shoot off in her throat. The feeling of Diana's tight throat and her smooth head in my hands made me cum so quickly; those and the fact that I was getting a fabulous blowjob from the Physics Girl.As Diana swallowed my cum, I ran my hands over her head. Looking down at Diana Cowern with my cock deep in her mouth, was more than unbelievable. I knew that I would never forget the blowjob I got from her on the roof of the VAB. So, I grabbed my cell phone. The last argument that we had was just me being pigheaded. It was all my fault and I wanted to make up almost immediately, but my stupid pride got in the way. You know the old saying – "Don't apologize, it is a sign of weakness" – well that is what was bouncing around in my head." So why now?" Because I don't want to lose you to some other girl." You might be a little too late there Julie. Mary and I seem to have a very good thing going." Don't say that Wally. You're my guy. You were put here.
