Denial of pleasure

"You have to hold me while I fuck these two. You can't touch yourself. I won't touch you. They won't touch you. Got it?"
"Yes, Master," Wendy/Hyper-Girl says sadly.
"Now then, let's set Alex and Fran up for their final bit of conversion..."

You have the superheroine duo untie the pair from their respective chairs, placed face-to-face & tied with their legs and arms wrapped around each other. Now for the real fun.

You have Power Woman (aka Coach Sampson) lift the bound duo up in the air over her head. She can easily hold the duo, as she often bench presses cars as a warm-up.

You make Hyper-Girl grab a hold of you from behind and lift the two of you up into the air. She floats you right in front of the bound and naked Cheerleader duo to fuck.

You grab Alex's ass, but stick your dick into Fran's pussy first. She's on the bottom, so this is easier.

You thrust into her, finding more than lubed up by the previous several minutes. You also feel Wendy's wet pussy against your ass as you fuck the girl.

"Don't try to rub one off against me," you say, glancing back, "If you try to trick me, I'm going to make you my powerless slave."
"Yes, Master," she replies fearfully.

Using your powers' previous actions, you can go the distance quite easily here. You make Fran cum and then switch targets.

Raised up slightly, you can fuck Alex now quite easily and do so until she cums as well. All the while, you slap Fran's thighs, which she loves!

You switch back and forth between the pair three more times before you feel you own orgasm approach.
