LULU-442 — I used the sticky nipple development techniques I learned from erotic manga to make the large, defenseless breasts of my pale-skinned, anime-loving, introverted otaku friend's areolas sensitive, and then had a blast playing with her nipples until she came.

This is the story of two introverted otaku, a man and a woman, who became friends because of their love for anime and manga, and decided to try out nipple stimulation techniques they learned from erotic manga. The male otaku couldn't resist the defenseless, braless breasts of the female otaku. He couldn't resist the sight of her nipples in person and started kneading her big boobs! He rubbed the nipples in the middle of her breasts, which were gradually hardening, causing them to shake and orgasm! They played with her sensitive nipples until they were completely hooked on nipple play! The introverts, whose sexual curiosity was escalating, spent their days playing with nipples and having sex until they ran out of sperm, cumming inside each other again and again!
