That part was always weird as fuck to me aswell.
You are loaded, pay 150-200g's for college ass, and then you have a silent quickie where you can be found out by your son, wife, buisness partners and colleagues, so basically risking everything ?
Jade shows us how its done, a motel where you can pay in cash and then you ravage that college ass all night and get your moneys worth.
And even if Burke needs the "dangerous" kick, you take her 2 cities over and fuck her in public, but if he tried anything at the prep party, its just suicide.
What we are led to believe has to have a different story behind it, otherwise it'll make the hall of fame for dumbest guy in a pr0n game ever.
