For a moment Stiles had thought about allowing Derek do as he spoke, to thrust his cock into his already stretched and very willing hole but then a Derek was getting onto his knees and Stiles wasn't going to argue. Not when Derek's mouth and tongue invaded his puckered hole. "Fuck! Master!" Then Derek's hand was on his hard and abused cock, slipping the ring off. It only took a few hard thrusts of Derek's tongue before Stiles was pushed over the edge he had been standing at since Derek slipped the vibrating plug into his hole.
"Master!" Stiles practically screamed Derek's title as his eyes rolled to the back of his head. His legs gave out as he came all over his himself and he slumped to the ground unable to hold himself up.
