A little foreplay

Mama walks off and then comes back with some more rope and nipple clamps.

"Let's see." She starts to put both clamps on Yoki's nipples making her hiss in pain as Mama plays with the chain that connects the two.

"Yeah, that should do nicely."

Mama then uses the extra rope to wrap around Yoki's arms and then throw it up high on the hook to the ceiling.

She snugs it hard and Mama walks in front of Yoki and pulls on the chain, "Can you move closer to me?"

Yoki groans louder but couldn't as the rope to the ceiling prevented her.

"Good."

Mama then went off screen and comes back with a dildo on a pole. She pushes Yoki's skirt up and her legs open and slides the cock into the schoolgirl's pussy.

Yoki looks at Mama defiantly.

"Ride it!"

Yoki doesn't.

Mama comes back with a tazer, "I said, ride it!"

She starts zap Yoki, making her scream in pain as Mama walks around zapping her. Yoki soon thrust herself on the cock.

"Yeah, that's what I thought, for a tough girl like you to break you need a tough tool. And there's nothing tougher then electricity. Wouldn't you say, Yoki?"

Yoki starts cursing Mama in Japanese with her breasts flopping with each thrust of the dildo.

Mama chuckles and zaps her some more, "That's right keep fighting. It makes me horny the more you fight."

"Ahh! Kuso!" Yoki moans as she looks up and starts to cum.

"Oh?" Mama walks over and puts the tazer down and got a Hitachi wand before putting her hands on Yoki's shoulders, "Did you cum?"

Yoki doesn't say anything.

"Then I guess you won't be needing this?"

Mama rips off Yoki's skirt and puts the wand against Yoki's pussy while spreading her pussy lips with her other hand.

"Ahh!" Yoki groans as Mama has the wand up to the highest setting.

"What's wrong, Yoki. Feel ready to cum again?"

"Eeeh!" Yoki groans as she looks at Mama and slowly shakes her head yes.

"Well..." Mama turns off the vibrator, "Too bad. You already had one orgasm without permission. You don't get another."

She then licks the side of Yoki's face and walks off laughing while Mama walks off.
