You see a guy around your age

You turn around and see a guy roughly the same age as you. He's looking furious! "You asshole, that's my girlfriend!"

Guess that answers your question. Emma does have a boyfriend. Lucky bastard.

"Look, I can explain", you tell him and ready your Sharpie. You grab the guy by the arm and quickly scribble "RYAN'S BUDDY" on it. He instantly calms down. "Never mind, buddy!", he says.

"Shit, it really did work!", you exclaim. "So, you're my buddy now?", you ask the guy. "Yeah, I'm your buddy, Ryan", he says. "So... errrr... you don't mind if I finish jacking at your girlfriend?", you ask with a grin. "No, go ahead. That's what friends are for", the guy says cheerfully. "What's your name, by the way?", you ask. "Thomas", he says.

You continue spying on Emma and resume your stroking. Your mind wanders to your newly won buddy standing next to you. You don't really look at guys that way, but you realize Thomas is really good looking. "That's a no-brainer, really", you think to yourself, "Emma is a ten. Of course she would be dating another ten. I wonder if he has..."

Then, out of a whim, you grab Thomas' arm and complete the text to say "RYAN'S JACKING BUDDY". This prompts a change in Thomas' behavior. He says: "Hey, let me have a look too!" and starts spying on her own girlfriend through the hole. As he does so, he digs out his penis from his pants. As you guessed, it is HUGE! You take turns peering through the hole and stroke your dicks. When it is Thomas' turn to look, you admire his massive member and imagine what it looks like when titty fucking Emma's huge monster titties. This thought of this us too much for you to bear. Your dick starts twitching and shooting ropes of cum all over the place. Thomas notices this and releases immediately. He spews out an enormous amount of thick cum.
