Big balls!” Lisa groaned. “I love them, your hot cock and your big balls! You’ve got to come up my ass ... I want that come juice flooding my fu...king hot asshole, darling!”Mike could hardly wait to come. He had been in danger of coming as he tongued her asshole, and now that his cock was being gripped so hotly by it, he didn’t try to hold it back. He rammed his prick hard and deep into his mother’s asshole, grunting as he pressed.“Ohhhh, yes!” Lisa screeched when she felt her son’s cock. I recognized it too. It was Jyoti’s I was dumbfounded.

Her own tits popped out of the bustier style top.Oh, well, here goes, thought Jennifer. Leaning back towards her aunt, she asked, “Anything else bartered for, here?” and took. I went back in.“Better?” she asked.“Definitely better, but you’ve got to get up on your toes more when he brings his racquet back to serve,” I explained. “You’re delaying because you know he doesn’t have the power. Stop thinking of him as John your trainer and start thinking of him as Yuri Gedov. You can’t let him slip one by on you.”She absolutely beamed at me and turned back to the game as I went back outside to watch. About every five to ten rallies, I’d pop back in and tell them what I saw..
