You decide that its time to show him who has more endurance. You slide a double sided dildo into his anus, before inserting the other end into yours. You start to move your hips, slamming your butt against his as you both ride the toy. It won't be long until his cock is spurting.

Challenge him to a dildo duel

Don't worry, both sides have been lubed!

He pushes you onto your back, and before you can protest, a large, double sided dildo is inserted into your backdoor! You watch as he slips the other end into his own hole, before he starts to move his hips, slamming his buttcheeks against yours as you both ride! Time to focus, or this might cause you to cum!
