A test of obedience

The next scenes shows Yoki on her knees in leather armbinders with the electric plugs still in her ass and pussy.

Yoki squirms uncomfortably as the hum of the batteries are heard doing their work giving Yoki a stingy sensation.

Mama walks over with a glass electric strapon around her waist as she sits in the chair.

"Okay, Yoki. Let's see how much you learn."

Mama turns on the battery attach to her strapon and she then uses her hand to push on the back of Yoki's head.

Yoki hesitates at first in fear of being zapped.

"Come on Yoki, you know the only way to get those stingy painful plugs out of you is if you obey, so suck it."

Yoki finally sucks it, turning this way and that as her tongue slowly licks Mama's cock, getting zapped but keeping her composure as Mama then slams the cock into her mouth and thrust into her.

Mama turns up the volume as she face fucks Yoki. Not stopping with Yoki crying in pain while the insides of her mouth gets zapped.

Finally, the MILF stops and pulls out.

"Ready for hole one?"

Yoki, her hair disheveled and tears escaping her eyes, nods her head.

"Good."

Mama walks over to Yoki and gets on her knees. She then slowly pulls out the dildo in Yoki's ass making Yoki say something in Japanese with relief.

But that soon change as Mama slides her own electric cock into Yoki's ass.

"Ahh!" Yoki cries as Mama just goes in hard and fast, pulling on Yoki's hair.

"Come on, fuck me back. I'm not doing all the work! Fuck..."

Slap!

Mama slaps Yoki's ass.

"Me..."

Slap!

"Back!"

Yoki cries out as she fucks Mama's cock, it didn't help when Mama turns up the electricity.

Soon Mama asked as she really fucks Yoki's ass, "You want to cum?"

Yoki nods her head.

"You know the magic word!"

"Please..."

"Please what?"

"Please... mistress."

"Yes, cum! Cum for mistress!"

"Ahh!" Yoki cries as she cums with a electric cock in her ass.

Mama then stops and pulls out. She undoes Yoki's armbinders and spin the dom around. She and Yoki kiss before she pushes Yoki's head down and makes her suck on Mama's nipples, getting some milk.

The MILF then push the dom with the milk mustache onto her back.

"Okay, for hole two."

Mama then pulls the second dildo out of Yoki's pussy before she grabs Yoki's legs and drives the cock into Yoki.

Yoki cries as Mama's electric cock slams and shocks her up pussy. Really driving it into Yoki as Mama pinches and pulls on her nipples.

Soon, Yoki's breathing became erratic.

"Can I please cum mistress? Please?"

"I didn't even have to ask you first." Mama chuckles, "Good girl, but no!"

Yoki groans.

"Keep going!"

Yoki slides herself on the floor, driving herself on her mistress cock as Mama turns the electricity a bit more making Yoki cries out.

After a second plea for Yoki cum again, Mama yells, "Cum damn it! Cum for your mistress!"

"Ahh!" Yoki cries as she cums all over the electric cock.

Mama slaps Yoki's thighs before she gets up and pulls Yoki up on her knees.

"I'm not goin to make you suck on the cock again, as I know you hate it."

Mama turns off the cock and tears it.

"But you will lick me, show how truly broken you are."

Yoki, with a push of Mama's hand starts to eat Mama out as the MILF grabs the camcorder and looks down at Yoki.

"Oh yeah... right there. So tell me Yoki, what did you think of our session?"

Yoki, with her mouth full of pussy, said, looking up, "I liked it mistress..."

"Hmm, will you come back again?

Yoki nods her head while her tongue is seen working on Mama's clit.

"Good girl. I glad to hear it. Now get back to work. You almost got me to the edge. Oh shit!"

Mama groans as she starts to orgasm in Yoki's face while the schoolgirl dom continues to lick Mama out before the camera turns off.
