Give me Credence, kneeling under Graves' desk, ever-so-slowly nursing at Graves' soft cock while he goes about his workday. Preferably something that involves other people in the room--meetings or performance reviews, something along those lines--Credence staying silent and keeping Graves' cock nice and warm and wet until Graves decides he's been productive enough for one day and allows himself the reward of getting hard and fucking Credence's mouth until he comes.
