Art and Jon's dad left to make love.
"you honey, before we make love I got to drain the pussy" Art said heading for the bathroom. He scowled in disgust as he wiped himself. At times he wished he had a dick, it'd be easier. Not that he minds fucking his lovers dick with his tight hole. And yes, to art he WAS the one doing the fucking not the one being fucked.
After taking a leak he started stepping out the bathroom door and almost tripped as something small and rouded rolled out from under his feet. He swore loudly and picked it up. It was a damn rock, likely left over from jons geology class project or something. Art went to toss the damn rock outside muttering under his breath the whole time. "damn kid leaves his stuff on the ground where anyone can trip over it, he should really learn not to leave his stuff lying around. I tell you it takes real balls to do something that stupid. and balls, I wish I had balls, and a nice dick to go with it."
He tossed the stone out on the driveway where it rolled and eventually settled next to other similar non magical rocks.
Jon's father called out "I heard you yell dear, is everything ok?"
"It's fine" art said. "I almost tripped over a damn rock that is all. I am ready to make love to you now."
and so Art headed to Jon's fathers room oblivious to his new penis and balls.
