Jeff in the time the three of them were waiting for Zach decided to make some more changes. Using the Chronivac , Jeff made some modifications to himself. Firstly he made his balls bigger and heavier, along with giving them increased cum generation and a bigger libido. Secondly he changed Dan and Mike slightly, making them both bigger sluts than they already were, and thirdly gave Zach a bigger cock that could spurt endless amounts of cum when he wanted to.
Jeff started jacking off again as he felt his balls become even more swollen with new cum. Not caring, he started spurting his wolf culture all over his room before returning to the living room where he saw both Dan and Mike on the couch bending over and presenting their slutty cum stained butts to Jeff. Seeing the sight, Jeff came instantly before his cock almost immediately hardened once more.
“Big bro please I need your fat cock.” Dan said, wagging his butt seductively before Mike interrupted him “No way! You probably have had sex with him way more than I have! Let me sit on his thick cock!” Mike said, his young canine cock already dripping with Pre cum.
“Enough what we have to share don’t we? Mike sit on Dan’s cock and try that before you can use me again, Dan you know what to do.”
The two kids obeyed obediently, Mike sitting his slutty ass on Dan’s fine cock.
Then Jeff had Dan sit on his cock and together they started humping away at each other in a sexy threesome, Jeff penetrating Dan whilst he penetrated Mike. Mike could only yell out as Dan groped Mike’s balls as he shoved his knot into the fox whilst Jeff gave Mike the handjob of his life.
The fucking continued for what seemed like hours, until they all heard the door bell ring, and without asking anyone, a young naked anthro monkey game in, his huge cock for his age already hard from the musky smells of the fucking.
The monkey smiled before saying “Can I join in too?” Grinning.
