Cuck fingers and fucks his married sister in her husband's bed

Cuck fingers and fucks his married sister in her husband's bed while the husband sits in the living room saying nothing for the money it brings. Both live in the same building in Mansoura and he goes up to his sister every day on a work excuse while the husband goes down to the cafe. Into the bedroom he pulled her by the wrist, stripped the robe off, sucked her tits and nipples, fingered her pussy until she was dripping, then lay in the husband's spot and let her straddle his cock through the whole fuck. Midnight the husband came back, found them naked and stood watching from the door while he kept fucking her hard in a clip with no mercy, her ass shaking and her moans impossible to hold in.
