John giggled as he stumbled into Sherlock's bedroom and pushed Greg onto the bed.
"Oh god." he exclaimed, before slurring out, "Sherlock'll kill us."
Greg snorted loudly, and John giggled some more.
"What the hell was in that drink?" the doctor asked, rolling Greg under him and pinning his arms above his head.
Greg thrust his hips up against John, trying to get more pressure; more friction; more... John.
John grinned back at him, menacingly, before swooping down and capturing the Detective Inspector's mouth with his own, sliding his tongue along Greg's lips.
Greg groaned, opening up to allow John full entry, and wrapped his legs around the doctor's hips, pressing their crotches together.
"Dammit!" John cried, releasing Greg's hands and, in three swift movements, divesting himself of his t-shirt and both of their trousers and pants. Greg slid off his own shirt and lay back on the bed, his arms back above his head in full submission to his Captain.
John took in the wonder of Greg's naked form.
"Shit!" he exclaimed, and his cock bounced in agreement.
Greg looked up at John, silently beckoning him down again and pressed his heels to John's arse as their cocks ground together.
John claimed Greg's mouth a second time, swallowing moans from both men.
He wanted Greg, and he wanted him bad.
