Mark sat through the rest of the day thinking of what he should do to get back at Sean finally settling on a plan he thought to be genius. Before the first day of vidcon ended he had to get Sean's phone when he wasn't paying attention and turn off his alarm, which he did. Mark would be the one waking him up the next morning.
Sean was still sleeping when Mark snuck into his room, 45 minutes before they needed to leave to Vidcon. Mark crawled over to Sean and hooked his fingers underneath his boxers and pajama bottoms, pulling them down just enough. Once Sean's member was out Mark wasted no time and began bobbing his head up and down, feeling Sean's erection grow. Mark noticed Sean's breath was quickening, he even let out a few moans in his sleep. Sean woke up before going over the edge and was confused but didn't care because it felt so good.
Mark heard Sean moan that he was close and he took that as his cue to pull away. "No, Mark please." Sean begged but Mark just smirked and said, "You've only got 10 minutes to get ready, sorry but you won't have time to deal with your situation." And walked out the door.
