"I rub it against stomach and Chiyuki is cute." I, Chiyuki, who has a short stature of 145 cm, was worried about the same 190 cm tall boy, Gen, but I like him. Knowing that there wasn't, the love ended before it started. One day, a crowded train, protected by a crowded place, had a strong abdominal muscle in front of me. When I was excited and touched my body innocently, I found something hard and hot in my stomach ...? This means that I'm lustful --- !!! ??? [Big guy] x [Small girlfriend] Doko and Kashiko are wrapped up in him of non-standard size !! After all, office love!
