You glomped your clone to your bed, and you started to hump his butt even though you both have your green boxers on. It might be weird for someone else, but to you and your clone, it's a fantasy that you want for a long time.
You both start rubbing each other's boxers, and it's super smooth. Your clone's butt also feels nicely round too! You might think whether that is clone or not. The thing is, you do have a sexy butt, and you are one hell of a sexy guy.
You've decided to fuck him for real, so you lowered your boxer-shorts, pulled your dick out, and started to hump into his butthole through his undie hole.
"Nnnngh~" moans start to fill in the room and you just kept on fucking, until you and your clone oozed some precum through the undie. All of the sudden, your clone turned around, hugging you and you both grind against each other's bulges.
"3... 2... 1...", you both cummed together through the underwear and you both are still grinding.
"So that's what it is like to fuck your clone...." you thought, even though your clone hasn't topped you yet.
