Monkey
They say AIDS started because someone fucked a monkey. No one fucks monkies and people.
Either you fuck monkies or you fuck people. If you cross the line and fuck a mopnkey there's no coming back from that. You can't go get some monkey pussy on Tuesday and then call Cheryl on Thursday. Either you fuck monkies or you fuck people.
You know how hard it is to catch a monkey. Let alone catch a monkey and fuck it. What monkey is going to hold still for that? Even as dumb as a monkey is, he's going to look back and be like "You ain't supposed to be fuckin me man." You know how strong a monkey is, that shit would rip your dick off like it was celery.
