The Lollipop Contest

 A groundkeeper used to watch girls playing on the playground in the park and with age decide to lure them and enjoy them in secluded areas. He has the idea of tricking them to suck on some meat by offering them popsicles, blindfolding them, presenting it like a game. 

He would pervert more and more girls, eventually sharing them with his friends and strangers making money out of it.

A rp focused on blowjobs only, keep in mind that the girls are naive but having a limited time allowed in the park playground and the thing needed to keep secret, their sweet mouth would be the only thing available.

I'll play the various girls.
