She really likes my new soft sweater and she wants to mess me with this outfit in front of her two friends. I said yes is it: savory mess sweet mess slime sticky mess
I have to let you decide...please be kind and gentle
In that case, I think a good-looking guy like you deserves to be totally humiliated, starting with a heavy focus on your boy parts/bulge.
I think I'd start the session off with several substances down the front of your pants/underwear (all over your dick and your balls); let's say a bottle of corn syrup or molasses (really sticky and viscous), a jar of cold apple sauce, a bottle of cold beer, an entire can of shaving foam, and a pitcher of ice water (including ALL the ice).
By the time you've enjoyed all of that, those pants should be good and wet and showing off everything down there quite nicely (so all the girls can see just how much you're enjoying yourself and just how well you do - or don't - measure up to expectations).
After that, I'd give a few pies to the face, just to bring you down another notch or two, before making you get down on your knees, pouring several bottles/jars of dark corn syrup or molasses all over you, and then dumping a bucket of feathers on you to finish things off.
If you were a good sport about it, I might also reward you with some more cold beer (or a very large pitcher of ice water) poured all over you, as well.
