"Rena likes it Frank. Shoot off in her mouth.", Devra added, pulling on both of Carol's nipples. "Fill her mouth with cum Frank. Let us taste your cum...", Ali urged. Rena lifted her mouth and looked right at Frank. "Cum in my mouth." she said lewdly, "Let me drink your cum." Frank groaned and felt it surging up his cock. A thick fountain of hot cum jumped out, leaping through several inches of space right into Rena's open mouth. The stream gushed for over one second and then she closed her mouth. I ached for his lips around my nipples which were so hard it was almost painful. I needed relief. I would have quite easily given in if he had just fingered me then and there on that bridge. However we were here for some sexy pictures and his voice asking me to pose for him snapped me back from my daydream. I became aware once more of how exposed I was yet I wanted to pose for him. I knew that we'd go home and we'd be alone so I wanted him as turned on and horny as I was. I leant against the. ..suddenly I quivered as an unexpected orgasm hit me, my pussy gripping Mary's fingers as it washed over me , I loosened the top two buttons on my shirt and pulled my tie looser as I saw Dave move behind Mary and push his hardening cock into her greying pussy as she carried on eating me out. My thighs tightened around her head as she brought me to the edge once again, I felt her tense as Dave's cock gave her the tinglings of a first orgasm, I was aware that Simon had moved to my side and had. ...I guess we matched as exhibitionist types too but we didn't really understand that then...only the thought of being seen by someone added to the sense of explicit and complete passion we shared.And it was one of these early evenings after we had stripped off together,she looked at me with what I can only call pure devilment in her sparkling blue eyes, when she reached down,picked up her lacy white panties and said "Put these on for me". Well, it was the two of us. No one else about. I didn't.
