Vince Time Wasters 9 requires Vandeels Chat 12 which, in addition to having done Vic Bro Chat 9 and Kubas Special Investigation 1 Intermission, requires Gittin' Vandeel Rocks Off 3
I've definitely done Vandeel, I'm pretty sure I've done Vic's Bro Chat 9, but I'm not 100% on the Special Investigation Intermission. I offer to hang out with Kubas a few times and 2 out of 3 of them involve him stopping to press me into his chest. That just raises my lust and repeats in a loop which leads to a gameover.
