A Zarry one shot (Smut): All Ears

Zayn and Harry have always liked each other, and they drop hints all the time. They are both afraid of rejection, so they just continue dropping hints, whether they are physical or verbal. They end up turning one another on all the time, and they have to 'sort the problem out' once they are too worked up and one has to leave. But they just get too into it and Harry has to 'use' the bathroom in his house with Zayn in the next room when he just can't wait long enough for the other to leave. Harry gets a little too loud, and Zayn overhears. What does Zayn do? The obvious. 'Use' the bathroom in Harry's living room. NAUGHTY BOYS!
