He needed to relieve his stress and wanted to release it as soon as possible. His balls kept bumping against Toxin's chin.

"I'm going to— HRRRRR!!"

Before he could finish, Grumps began to cum inside Toxin's mouth with thick, dense shots of old dog sperm straight into Toxtricity's stomach.

"HRRF!"

He couldn't be blamed: it had been quite some time since the former teacher had been intimate with another boy, and his balls were heavy.

He looked back at Toxin's jocks and stretched out his arms to grab his buttocks, slapping one of them.

"What a beautiful ass you have, mrrfff..."

The mutt growled and probed Toxin's mouth with his fingers, soaking them with his saliva. He grabbed his cock and slowly pushed it inside him.

"I'm going to put you in your place, but now get to work."

"Here you go, brat. Give it some good kisses."

It made him so horny that he called him 'sir'.

"Sorry... I didn't shower today..."

The old dog noticed Toxin's jocks and leaned over him to stretch the elastic.

"What the hell is this... I can see your ass..."

But it was a beautiful ass to use.
