My Impotent Coworker Licks My Inverted Nipples, Makes Them Stiff, and Fondles Them.

This is... unbelievably sexy to watch... He shouldn't say stuff like that with his crotch all hard and throbbing, or she'll be dripping wet in no time!

Kaoru Mizuki was recently dumped because of her inverted nipples, which she's insecure about. Meanwhile, her rival in work, Soichiro Ichinose, is such a specimen that there's no way he'd ever have issues in the bedroom. The rumors say he's the best and completely relentless... but then he reveals that he's impotent! Kaoru and Soichiro are like oil and water, but for some reason, she's the only one who excites him... This has to be some kind of joke. Still, Kaoru agrees to help him out, which is how she finds herself in his powerful arms, unable to move... If he goes any further, though, he'll remove her bra and reveal the secret of her inverted nipples...!!
