Kyonyuu x Roshutsu -K-cup Mogitate Kajitsu to L-Cup Ureta Kajitsu no Osoto de Pururun Aji Kurabe!-

The protagonist, Kyousuke Nagata, is a teacher who absolutely adores breasts and nudity. He quietly runs an image-sharing board for fellow breast lovers and exhibitionists. However, he never posts himself; his job is solely to delete dangerous images. One day, Nagata gains the best partners he could ask for. His student, Haruka Komae— “Ah... wh-what should I do... if he sees me like this, I...” She has a bright, honest personality, the type everyone likes, and is especially popular among the male students. She's kind, cute... and on top of that, well, with K-cup breasts, it'd be weird if she wasn't popular. Overwhelmed by his charm, she ends up giving him, a titjob in the classroom. Haruka's mother and Nagata's girlfriend, Natsumi Komae— “Sensei, no! Haruka will hear us...!” She's older than me, but we're dating. (Keep it a secret!). A size larger than Haruka's, she's a L-cup. She exudes a sweet, intoxicating sensuality like a ripe fruit. Unlike Haruka, whose lively smile and actions suit her, her refined, gentle demeanor is truly motherly, the epitome of an adult. Unable to suppress the instinct that had flared up, I pressed my body against hers. And then I realized. “They get excited when they think they might be seen!” What flashed through my mind were Natsumi's perfectly ripe L-cup breasts... and Haruka's firm, youthful K-cup breasts. “Guess blood is thicker than water...” After running a forum like this for years, you naturally learn where the best spots for exhibition play are. It was useless knowledge in real life until now, but this insight might come in handy going forward...
