Hannah's vibrator.

"I'm going to use my secret weapon, and you cannot resist!" Ashley told Heather. "No more than Hannah could!"

Heather gave Ashley a vague look. The cheerleader captain's body thrummed with the good vibrations Ashley had been giving her with her wicked little tongue. Who knew that a girl like Ashley with a hyperactive sex life with her boyfriend had been working on girls on the side? Much less her sister? But here Ashley was between Heather's legs after disrupting Heather's threesome with Taylor and Hannah, big sisters to Zack and Ashley and college roommates with an more-than-casual lesbian relationship.

"Brat, brat, brat!" Hannah said, regaining her big-sister composure.

"Now, ha-ha-ha!" Ashley said. She lifted up the vibrator she'd used for a sneak orgasm attack on Hannah and held it up high. The hefty ball-headed vibrator was still crowned with the special attachment with a peg sticking out the side. "Feel the power of the Wand of Lesbia!" Ashley nestled the projecting peg between Heather's pussy lips, questing for and penetrating Heather's vagina.

"Oh," Heather said as the peg, still wet with Hannah's juices, slipped inside.

Ashley snapped the power switch.

BZZZZ!

The vibrator took hold of Heather from the inside, the powerful sensations seeming to turn her inside out with pleasure. Ashley grinned. Hannah sighed at her annoying little sister. Taylor laughed in her low sexy voice and stroked Heather's hair.

"OHMYGOD!" Heather cried out. Her body tensed into a knot of pleasure, then flailed out as the pulses of orgasm seized her.

"EEEEK! She squirts!" Ashley said. Ashley blinked her eyes, trying to clear them of Heather's juices. "OW!" Heather's flailing foot caught her in the head. But Ashley held tight to the wand, wringing a big orgasm out of her team captain.

After a full minute of riding the waves of Outer Climax Space powered by a vibrating rocket, Heather begged for Ashley to stop.

Ashley said, "Pretty please?"

"PRETTY PLEASE STOP!" Heather cried out.

Heather's face and chest were flushed bright pink with orgasm and her brow was wet with sweat. Her head rolled from side to side. The scent of her aroused pussy tickled Ashley's nose.

"Nope," Ashley said. She twisted the vibrating peg inside Heather and pushed the broad ball head against Heather's pussy lips.

"AHHH!" Heather cried out hoarsely. "AHHH!"

"Okay," Ashley said. She snapped off the vibrator. Heather fell limply back, her head against Taylor's belly. She withdrew the vibrator and held it above her head. "I, Ashley Cheerleader Princess, have defeated three Lesbians in Sex Combat!"

"Brat," Hannah said.

Taylor blinked. "Ash, I thought you needed to scratch your own itch," the tall brunette said from under a limp, gasping Heather. "Didn't you say Brandon teased you until you had to do something about it?"

"Yeah, c'mere Ash," Hannah said.

Ashley came over to stand next to Hannah. Hannah curled one arm round Ashley's waist to hold her in place and placed the other hand on top of Ashley's smooth pussy mound. Sometime after she'd caught Brandon, her blonde pouf of a bush had disappeared.

"Can I get you off, Ash?" Hannah asked.
