Ok here is another idea

Time of year: the height of spring or mating season

Persons: sesshomaru, Kagome pairing and the inu-tachi

Plot: what happens when sesshomaru is very thirsty and drinks 3 of kagome's five hour energy which as it turns out is (for inus) a super aphrodisiac. Also sesshomaru is head over heals in love with kagome and the same could be said for kagome about sesshomaru.
