Jenn stands up and they embrace and kiss again. She pushes her bra-covered breasts into his bare chest. The man reaches behind her and unhooks her bra... He slips the straps off her shoulders and the bra falls off her. His hands immediately grope her tits. I watch as he knurls and tugs her aroused nipples and then bends down to suck her hardened nipples. The same nipples that I had sucked this morning. This goes on for about a minute as I stand there and watch realizing that my cock is rock hard.. I had to bite my lip to stop myself from telling her that I'd been between her legs, in her cunt, in her deliciously sexy little bottom, in her mouth, Christ just name a part of her body and I'd been there."And Andrea," she added, "It's Julie, not Miss Howard. You make me feel like a prim and proper school teacher when you call me that." No Julie," I giggled, "I could never see you as a prim and proper anything, never mind a school teacher, not the way you dress." What time do you close at. They were all avid voyeurs and though they had all done the nasty deed Grace was doing they enjoyed the sight more. Especially when the woman was mature, beautiful and ‘posh’. And she had actually asked for a young man to pee into her mouth. The ultimate in disgusting acts if you discount the doggie loving. And the plans they had for bestial love for Grace to partake in was already getting them excited. The beautiful woman had no idea what was in store for her. They were very optimistic Grace. I swore never do it again.But the hornyness is hard. Some time later I tried again but holding his cock with my hand. It was better. Controlling his cock made sex delicious. While holding the cock I learned about the knot. It amazed me the size it can reach and also I understood the reason dogs get stucked when they copulate.When my ass got used to his cock, I decided to stop using my hand to control. Big mistake. I thought due to the size of the knot it would be impossible to enter inside me..
