If Poe noticed the direction change, he didn't mention it, and instead just parted his lips to run his tongue along the ridge of the head of Finn's cock. His cock? Kind of about to suck his own dick, right now.

... Well, not like he didn't try it when he was younger. He pressed another kiss but then stopped wasting time, sliding his lips over the head and then quickly as far down the length that he could manage. Huh. Well, at least he knew that the size was perfectly respectable. He really needed to shut that part of his brain off? He really needed to.

His cheeks hollowed as he began to suck, the water still pouring down his face as he began to bob his head, his lips making lewd smacking sounds every time they nearly came off the end before taking the whole thing again and again.
