The poor, sad primate that has been tricked or forced into one's rectal cavity. It is very common for the monkey to reside in to sphincter for up to three weeks before voluntarily coming out.
Is that an arm coming out of you ass? HOLY SHIT!! IT'S AN ANAL DWELLING BUTT MONKEY!
During anal sex, the penetrative male "decorates" his erect penis with salad leaves and sauce, and then places strips of kebab meat over the ass cheeks of their partner then ejaculates once the salad leaves and sauce is inside the anus of the other - he will then proceed to eat the salad, sauce and semen from inside his partners ass.
Joe: Mm I'm starving for a kebab
Sarah: Oh me too baby, and I'm so horny... I fancy anal...
