Hide just behind the doorway and enjoy the show
From Create Your Own Story
You duck behind the doorframe and grab your package, giving it a good squeeze as you peek out at Dylan. He's really into his own cock, and you can hear him start moaning gently. It's more than you can take, and you unzip, pulling your cock out and jacking yourself.
For a minute or two, you synchronize your stroking with Dylan's. He's got his eyes closed, and he's turned, so you can see his cock again; it's obviously gotten bigger, and you lick your lips just thinking about it. Sliding your cock back into your trunks, you take a deep breath and get ready.
Your balls are boiling; it's time to make a choice.
