At last the stream picked up speed. Ahh... The morning piss: One of life's more underrated pleasures.He was as wet as if he'd come from the showers. A...solutely sopping. And the lightweight white drawstring pants were transparent. He shrugged mentally. At least the flag pole was down."Take them off before you come in here! You're soaked!"Okay. He'd been skinny dipping with Peggy and Susan. He was soft. It wasn't warm in the wind chill, so what the hell. He undid them and crawled into the dome. Our twin instincts made us match our rhythm perfectly, his left hand on his cock synchronized with my right hand on mine. Randy had said it, and he was correct. It sort of looked like rubbing one out at the bathroom sink.Except, there was no sink, and no mirror mounted over it. My brother was watching me fuck my fist, and I watched him do the same thing. Being teenagers, it didn't take us long at all to be ready. It was weird, watching my mirror image cum into his hand, as I shot my load. . The fact that we have history and that he still likes me only means that the sex would be better! And you two net getting along is irrelevant since I'm the one sleeping with him not you! And I thought that I'm free to sleep with whoever I want to!Me: you are free to sleep with anyone you want to! I'm just a bit uncomfortable about him specifically!Sue: listen, I left Chris for a million reasons! I don't have any feelings towards him so this is just sex for me, and who cares about his point of. "Am I hurting you?" he asked concernedly."God no," I gasped, "You're wonderful Mark, fuck me darling, fuck me."I think my language took him by surprise because I felt his cock stiffen and he growled."I've never heard you swear before." You've never fucked me before." God you're sexy." I'm going to come Mark." Yes," he grunted, "Shall I pull out?" No, oh fuck no." I'm coming, Maureen I'm coming." Yes," I hissed, "Yes shag me Mark, shoot it all up me, Mark, MARKKK..."He stayed all night and.
