Well, to start out, Pic #2 is just awesome. I love Chinese food!!!
Pic #1 is fascinating. Some nice torture going on here with a good back whipping and slicing of nipples. Alex's observation of the erect nipples on the dude to the left is correct - but either they are prominent, or swollen from some nipple torture. And that's an interesting splatter above his cock. Looks kinda like he - or someone - shot their load.
