Sirius didn't waste time. He started at the base of Remus" cock, swirling his tongue up his shaft to the precum already leaking from his tip, before he wrapped his lips around the head and sucked hard. Sirius took Moony’s length as far as he could and hollowed his cheeks, his hand swiping upwards to meet this mouth. Remus’ head slumped forward to his chest as he carded both hands through the man’s hair and started thrusting down his throat. He felt a momentary pang of guilt knowing that he was enjoying the company of someone other than his mate, but he needed this release, and Sirius" mouth felt incredible stretched around him. It was almost impossible to get himself off when the only person he wanted was off limits.
