The first time, my wife and I seduced my younger brother and she sucked him off while I fucked her doggy style. After that, we would have him over and She would suck us both off. Sometimes I would just watch him fuck her while I would stand at the foot of the bed and jack off. We did this for about a year off and on, trying different scenarios. One time I got underneath her in the 69 position and she sucked my dick while I licked her clit as he was fucking her doggy style. He came in her pussy and then I licked her clit and swollen pussy to an orgasm. I could taste his cum while I licked her pussy. Once he laid on the bed naked and she sucked his dick while locking eyes with me. She stared at me the whole time he was ejaculating in her mouth and she swallowed every bit of his cum while I masturbated and watched.
