Gone through all the hot tub sex scenes, all of them are fantastic, all of them are fun. That said, some stand out more than others, not because they were better, but because they're just so much fun.
The stand outs for me:
Morgan (I fucking love that pose and its one you don't see too often)
Palla (Again, love that pose and it just captures how hot and heavy she's getting)
Bree (The crouch is just so hot!)
Hanna (Fuck, holding her like that so she can't move, again, hot)
Samantha (She just looks so hungry for that)
Sasha (Actually one of the more romantic scenes, its a nice twist for the more sultry Sasha).
Its been a great update and the art really elevated it.
