S*S -Yuukai Shita ○ Gakusei o Love Love Ryoujoku!!-

A weird guy juggling a few part-time jobs
meets a young girl named Yui in the park one night.
She's a cocktease no doubt; he doesn't let her cast her lure only to be tossed
back in the water when he bites. However, while he does force himself
on her, she gets off as deeply as him. This is a r*pe story
about an unlikely couple who fit together like S and M. >:)
