Sherlock chuckled. "It wont end if you come, you sexy Demon." Sherlock rubbed his other hand up and down John's tail. "Of course, it will mean the end of these sheets, but I think that's already a given."

He looked under John and licked his lips and groaned. That huge Demon cock was leaking copiously, probably more than Sherlock had even come twice. "Fuck." He groaned. "That cock of yours..." He knew he wanted to try to beat his record of fucking John but damnit, that cock. It felt amazing to be speared open by it and filled to overfull by all the come in those large bollocks of his.
