Your Tan Gyaru Big Sister Will Relieve Your Sexual Needs if You’re a Good Boy (18+ doujin)

Mii’s childhood friend Mio used to be so sweet and protective… but that all changed when she entered high school. She turned into a gyaru, all flashy looks and attitude, and Mii was afraid he’d never close the distance between them again. He finally succeeds in getting into the same college prep school as Mio… and it turns out she was only keeping her distance from Mii to make sure she didn’t spoil him rotten, and ruin his motivation to succeed in life! But now that they’re going to the same school, she can give him all the reward and motivation he can take… and Mio’s bodacious figure has plenty of reward and motivation to give!
