Decide you want to watch the dildo stretch his hole
From Create Your Own Story
Dylan just smiles, hitching his thumbs into the waistband of his shorts and pulling them back down. His boxers must be on his bedroom floor--his cut dick is coming in around eight inches, and it's as thick as a can of Red Bull. You reach out and grab him, and his skin is still slippery from a shower rich with steam and gel soap.
"Uh uh uh," he scolds. "I've got a demonstration to give."
He sits on the couch, spreading his legs, showing off his tight ass. He spits on the dildo, working it between his cheeks, and your own cock throbs as you see it hit his pink jock pucker, see the look on his face as he loses himself in the feeling.
As you take a step forward, Dylan pushes the dildo inside himself, and he moans out loud. He grabs his cock, jerking it as he starts fucking himself with the big plastic tool.
"Ohhhhh," he moans. "Awww, fuck, yeah."
The little balls attached to the dildo press into his crack as he bottoms out, and his moans cut off abruptly. He furiously jacks his cock, and suddenly white-hot spunk is spurting all over his abs. He whimpers just a bit, and that's all you can take, stepping up the rest of the way.
What do you do?
