"Now," she says turning to show more of her ass and pussy to you, "Play with your perinium for two minutes, while you simultaneously squeeze your cock hard with your dominant hand and give yourself some powerful strokes!"
You ask her what your perinium is.
"It's right behind your ball sack and in front of your asshole," she says, showing you with her hand. "It's connected to your prostate, so it should help get your powerfully turned on!"
You do it and it's true, you start dripping pre-cum immediately and feel very horny and turned on.
