Shenanigans
Disclaimer: I don't own Sherlock or anything.
On a warm sunny day on a beach in Spain, Sherlock and John were swimming out into the ocean together. They wanted to reach the buoy and the swim back.
As they set off John began to feel light headed but chose to ignore it. Sherlock smiled as he excelled past his husband. But then the comforting sound of his husband's breathing behind him disappeared. Sherlock turned to see his husband had gone under the water, he panicked and quickly dove down, soon found John's limp body. He swam up and towards the shore of the deserted beach.
Once he reached the shore John's body was laid on the ground. Sherlock thought back to the first aid course John had forced him to take. Sherlock quickly found the place on John's chest to perform CPR. He pressed down five times and then pinched John's nose, opened his mouth and breathed into him, causing John's body to convulse as he choked up the water.
Sherlock held John close and rubbed his back. John's breathing soon calmed and Sherlock said "Never do that to me again. I thought I'd lost you." Sherlock tried with all his might to hold back his tears of relief.
John smiled reassuringly and once he had got his breath back properly he drew Sherlock into a passionate and love-filled kiss. Sherlock heatedly reciprocated and after a few moments drew back.
"What caused you to go under, Doctor?" he asked.
"I think the heat made me faint. I felt rather disorientated before it went black."
Sherlock could only stare at him and drew him back into the passionate kiss and the night they spent at their hotel in Spain was one that without a doubt they would remember.
