Sherlock stood behind John with a satisfy look on his face as he observed the slighter shorter teen arrive to his car with a horrified look on his face as he noted the stage of his car's hood which had been bathed with guts and embalming chemicals still dripping from the stolen frog and pig intestines placed on it spelling out a prom proposal. Sherlock stolen the bodies from their advance Biology class to spell out very carefully his proposal to John to be his date.
John didn't know if he was more infuriated with Sherlock for ruining his dad's car or flattered by what must have been in Sherlock's mind a very romantic way of asking him to prom.
As John was pinpointing his feeling towards Sherlock's little proposal he heard Sherlock step next to him smiling obviously pleases with himself.
'So will you go to prom with me John?'
"I'll think about it after I clean my car with your face asshole!"
Sherlock was going to explain his reasons for the surprise when John garbed him by the shirt's collar violently pulling him into a passionate kiss letting go after what seemed hours releasing a very confused and shocked Sherlock.
"Of course I'll go with you. You selfish bastard" John smiled
"Um…are you still going to clean your car with my face?" Sherlock said finally after a long while of processing his feelings.
John got on his toes and kissed Sherlock's cheek gently saying with a smile
"I would because I'm mad enough to do it but thought it would be more fun if we washed it together."
