摘自本作简介中该角色的段落

Mariko’s superior at work. Handsome, successful, and knows how to get what he wants. He’s particularly gifted in bed, owing to his prodigious equipment and difficulty achieving climax. He sets his sights on Mariko, in an attempt to steal her away from her husband. The fantastic sex is enough to keep her coming back, but will it win her heart as well? [From MangaGamer]
