He can't

Ryan puts a hand over his mouth but can't stop himself from moaning. You look up at him, mouth full of cock, seeing his now worried and aroused face.

"I don't know what the fuck has gotten into you Jason, but cut it ...unnnggghhh fuck... cut it out." he says trying to focus on talking to you without his eyes rolling back in his head. You smile and ignore his request, instead opting to suck faster, helping your mouth out by wrapping your hand around the cock and jacking it as well. "Uuunnnngh Fuccckkkkk," Ryan moans uncontrollably, although you couldn't see anyone other than Ryan from your position, that was enough. From Ryan's frantic glances and eye contact, you can tell people are beginning to notice.

"Ryan, is everything alright," you hear Mr. Milken's voice ask from the front of the class.

"Yes, sir. Sorry, just get excited about...uhhh...Shakespeare." Ryan puts both hands on your head trying to push you off his cock. You resist, your face turning red, but he makes progress, his cock sliding out of your throat with a bounce. Your hand still jacking him, you desperately stick Jason's tongue out, trying to lick the saliva and precum there.

"Well Ryan if that is the case, then perhaps you might be interested in taking another course as this class is about post-modern literature and, as you may know, the bard live quite a while before WW2." Mr. Milken replies. You feel Ryan's body shiver and then you feel it in your hand, the pumping of hot white cum.

"Oooohhhh yeeaaahhhh..." Ryan moans as he uncontrollably shoots wads of hot sticky cum all over his best friend's face.

"Well....I applaud your enthusiasm Ryan if nothing else." Mr. Miken continues and then continues with the lesson.
