He fucks it up naturally

Timmy gets up and yells at Mama while he charges at her.

Mama naturally back elbows him in the jaw.

"Don't scream dear. You let me know you are coming."

Mama then looks back up at the ring and sees Tiger now next to Minotaur. Both watching and yet still no Hera.

Mama then grabs Timmy's cock.

"And speaking of coming."

She strokes her son's cock, till its nice and hard which didn't take long and inserts it into Petty's ass.

"Ugh!" Petty moans.

"Sorry, my love. But you were going to have to it up the ass sooner or later."

She forces Timmy to lean deeper into his sister while she ties Timmy's arms with the ropes so she wouldn't get free.

Mama then slides out of the ring and gets a large strapon, thick and large.

Mama then slides back in and looks one more time at the two women staring at her from the ramp.

"Okay, my babies." Mama says spitting on her cock and lubing it up, "I warned you what would happen if you didn't give it you all. Here we go!"

Mama then slides the cock into Timmy's ass.

Timmy and Petty then start to scream as Mama starts to fuck Timmy and thus forcing Timmy to fuck Petty.
