By rendering Ultramom utterly helpless

Kim leaned down as she was slamming her strapon into Ultramoms hot twat and whispered.

"Do you trust me....?"

Ultramom whimpered but nodded.

"Okay, I'm gonna pull out for just a second to get something I need."

Ultramom groaned as the big fake cock was slowly withdrawn from her cunt. Kim quickly tiptoed over to her bag wher she picked up four items, a ball gag, a communicator, a rag and a bottle of ether. Coming back behind Ultramom, Kim whispered in her ear.

"You said you trusted me right?"

Ultramom nodded.

"Well, open your mouth please...."

Ultramom complied gasping as she felt something wedge into her mouth and a strap being done up behind her head. Kim rammed the strapon back into the sopping wet honeybox that it had been plowing away at. Ultramom grunted as the strapon bottomed out inside of her. Kim kept thrusting her hips whilst leaning the top half of her body away from her prey's back as she poured some ether onto the rag.

Ultramom smelt something funny in the air but couldn't defend herself as Kim smothered the heroine's nose and mouth with the rag, Ultramom tried to fight it but with her hands cuffed to the bedframe and the ball gag in her mouth, she couldn't resist and very quickly succumbed to the effects of the ether.

Kim pulled out, smiling to herself at how easy this plan had unfolded, the false callout to a bank over five miles away would mean that by the time Ultraboy got back, his mom would be long gone. Kim reached for the communicator.

"It's done, she's ready for pick up....yes, her idiot son is nowhere near, but don't be too long, I want to proceed with our plan....OK, see you soon..."
