“What is that?”
“I thought it rather obvious. It’s a present.”
“Have you ever seen me give presents to anybody else?”
Fair point. John is still suspicious. But he opens the plain box nevertheless. Sherlock watches him unwrap the object with suspense.
“This is not really a present just for me, is it?” John grins.
Sherlock’s grin is equally broad. “Selflessness is really not my strong suit. They had some kind of special offer at the shop and it said there would be an additional item in there.”
John rummages in the box and pulls the item out. Then he snorts, “Oh, that is just wrong!” He throws the bottle over his shoulder and it lands somewhere between the sofa cushions.
Still grinning he turns back to Sherlock, “No time like the present, hu?” and disappears into the bedroom, Sherlock on his heels.
A couple of days later Sherlock is in the bedroom while Mrs Hudson potters about the flat.
“Sherlock, dear, how often have I told you that food does belong in the kitchen? I put your ice cream topping into the left cupboard.”
Sherlock blinks. Ice cream topping?
He gets up, walks into the kitchen and opens the left cupboard. Next to the honey and the maple syrup sits a bottle that says ‘Anal lubricant. Flavour: Banana’.
