Big Dog Girl, Small Dog Heart: Sensitive Nipples

Synopsis

Tabasa is a tall girl with huge breasts who has many friends but struggles a bit with studying.

She admires Yuki, an honor student and genius, and spends her days masturbating instead of studying while harboring conflicted feelings.

The two suddenly grow closer due to certain circumstances. Tabasa becomes nervous and defensive like a chihuahua in front of Yuki, but meanwhile, Yuki has developed an aphrodisiac that targets nipples and sets her sights on Tabasa’s large assets———

Driven mad by the aphrodisiac, Tabasa becomes addicted not just to nipple play, but to mutual masturbation and lesbian sex with a size difference.
