A/N: This is based on a dream I had the other night (hence the title), in which I was Sherlock. Just some short pwp. I realise my writing is a bit stiff, and just generally a bit not good, but I'm dealing with a very serious case of writer's block at the moment and it has greatly impeded my writing abilities.
– A good dream –
John lay panting on the bed. Sherlock kneeled over him, slowly working a dildo in and out of John's arse. Sherlock leant down for a kiss, catching John's bottom lip between his and gently sucking. John sighed as Sherlock released his lip and moved lower to leave a trail of kisses down his neck. When Sherlock's lips found the junction between John's neck and shoulder he stopped kissing, and moved instead to gently nibble and lick his way along John's collarbone. John moaned at the feeling of Sherlock's teeth scraping over his skin, his hips thrusting into the air in time with the dildo being thrust inside of him. Sherlock removed his lips from John's skin and stopped moving the dildo, causing John to let out a frustrated groan. He sat back on his heels to admire John's appearance: hair ruffled, skin glistening, penis leaking fluid onto his own stomach.
John smirked as he watched Sherlock watching him. "Is that all you've got?"
Sherlock blushed at the question. He removed the dildo from John's arse, causing John to gasp, and tossed it aside. The dildo was quickly replaced by Sherlock's penis. Sherlock gripped John's hips, nails biting into his skin, as he quickened his pace. Soon Sherlock was slamming into John with abandon. He removed one hand from John's hips to grip the headboard for support.
John wrapped his legs around Sherlock's waist, drawing him closer. He arched his back against the bed as he moved one hand down his body to wrap around his penis. His other hand fisted into the covers by his head as he stroked himself. Sherlock's forehead dipped down to meet his, and he tilted his face upwards to capture Sherlock's lips with his own. He moaned into Sherlock's mouth as he came over his own chest and stomach. Sherlock continued to thrust in and out of him, and finished inside of him soon after.
