You're almost correct on the jackhammers. His most famous anals like Kristy Black, Sasha Beart, Martina Smeraldi, Jane Wilde, Gia Derza, Kissa Sins: all 6 are well known anal queens, some I haven't even mentioned. THOSE ones he'll jackhammer. If it's a girl he doesn't know like Morgpie, PAWGEmily (who actually managed quite a bit of anal), MagNumb (who wanted anal from the jump so her he jackhammered), Niykee Cruz (who had fucked pro only 3 times her whole life but she's an escort...he flirted anal with but wasn't sure it'd be all anal til it happened) he goes easy. Again! It all depends how Morg is when she walks into the hotel room or wherever they're supposed to fuck: there's always a 15-20 min convo before anything happens how it's gonna go down position by position, then I ASSUME throughout he checks their comfort level and reminds them what's up next position wise.
