Let's Do It Already!, Vol. 7

His rule: No sexual relations until age 18! Her rule: No rules. Free-spirited Yuri Hasegawa and straitlaced Keiichiro Katsuragi have fallen in love. But his elite political family-producing a line of prime ministers-does not allow male descendants to engage in any sexual relations until they are 18. Can the physically affectionate Yuri and rule-abiding Keiichiro keep their relationship strictly chaste? December 25 is Keiichiro's birthday, and Yuri's been hard at work at her part-time jobs in order to throw a lovey-dovey, hot, super-gorgeous birthday party for Keiichiro-until he tells her not to bother, that is! Christmas is supposed to be the time for couples to celebrate together, but it seems there's only trouble on the horizon!
