Jacob pulled out a bulb shaped item that was hard and cool to the touch. Rolling it around in his hand, he notices that it's got different shapes and runes embossed on it. After holding it for a while, he realizes that it's some kind of butt plug.
"Gross!" Jacob groaned tossing the item back into the box. "I can't believe that they would give me something like this."
He glanced at the box out of disgust and mild curiosity. Then, he decided that he had a while until his parents got home and nobody would know if he used it or not.
He picked up the old looking toy and examined it again. Then, with more than a little hesitation, he shucked off his pants. He spit on the toy and began to work it on his tight hole. There was a lot of resistance but eventually he got it inside. He sat laid there feeling the awkward fullness and stretched feeling and then he sat up on his bed. The motion of sitting on his bed made the toy shift uncomfortably deeper into his rear.
"Ouch, this is miserable. I don't understand why anyone would want this," he said out loud to himself, "I wish this weren't so uncomfortable."
In an instant, the feeling he was receiving from the plug became less of an irritation and more of a stimulation. He noticed that he was getting hard from the pressure of the toy.
He began to work his modest endowment when he said to himself, "I wish I was bigger." He watched in amazement as his cock began to push out from him growing in length and proportion.
