”How did you manage to hide this lewdness under that suit?” Kudo is a successful elite office worker, but he's always been regretting he didn't know real love. When he meets younger - but daring and intriguing - carpenter Sato, he finds himself unable to resist the pleasure of being possessed by a man, even though, as a supposedly straight man, he feels he should find it demeaning. But, Sato doesn't hide that he's serious about Kudo, and pushes him to go one step beyond the tentative, fake relationships he's tried to build with women until now…?! A grown-up first love story, vividly awaking the feelings you discover when you seriously fall for someone for the first time in your life. ※本書は、現在配信している「アンダーマイスキン【単行本版（電子限定描き下ろし付）】」の英語版になります。内容は同じですので、重複購入にご注意下さい。また、特典は収録されておりません。
