The entire rowing machine was jerking and bucking with the force of their shared climax. Martin's knuckles were bone-white, gripping the oar-handles. ...he nails of Jacqui's imprisoned hands were digging deeply into the flesh of his back.At last the spasms of their climaxes began to subside. The clatter of the rowing machine died away to a faint metronomic rattle. Jacqui sighed heavily and rested her chin on her nephew's big shoulder."Wow," she breathed. She sat astride his massive prick, feeling. I sucked his dick good, licking his balls and running my tongue up and down his shaft, and telling him in between that I wanna see this dick make Emme's pussy cum again. He told me to put his dick in her wet pussy, guide him in. Holding his dick, I rubbed it against her wet cunt telling her she's about to get fucked good. He thrust his dick in, pumping her in and out slowly, asking me if I like what I see. I grabbed our cell phone and started taking pictures!! Emme was getting more turned on by. I decided that Anne should learn how to handle the boat for when I had to visit the toilet, bar etc., so I called for her to come up onto the bridge once there I left them to get to grips with the lesson and went down to visit the toilet and get myself a beer and enjoy our new acquisition.Twenty minutes later I returned to the bridge to find Steve getting a hand job from my darling wife, it appeared that Anne's bikini took his mind of the lessons and his large erection erased any thought of. . as she removed her shirt I saw that she was wearing a black bra and those wondrous white globes of hers were waiting to free themselves from captivity…Her navel looked like a well with sweet water just waiting for somebody to quench his thirst from it.. As I saw her like this I completely lost my senses and was dumbfounded at this exquisite sight.. my sister watching me through the mirror said with a mischievous twinkle in her eye and slight grin on her face,sis: What are seeing bro..? never.
