I've tried this and get bored with it. Too many games, and no reward, it's like middle school dating.
Had one girl recently at a legit, she would take off the sheet half way through the massage, waved it a bit and put it back on, saying "just making sure it's nice and smooth". I know she was looking at my ass.
Same thing happened at the turn, slightest of dick grazing, for sure ball grazing. But she lifted the sheet again and stared at my cock for like 3 seconds straight before finally putting the sheet back on. Stretched me out and had her hips right up against my balls.
Went 3 times and the 3rd I just had to ask at the end, if I can get a massage somewhere else. You'd think that would lead to some flirting but it was just "somewhere else? uhh, nothing else, just get up slowly so you don't get headache".
Like I'm not a teen anymore where I get a hard on just from a girl touching my hand, need some juice at the end of the squeeze, I can't even squeeze here though!
