Hannah tells him to sit down

Zack calmly closed the door behind him and turned back to the girls with a hungry grin that no one had ever seen on his face, mirroring Heather's look. Zack's naked erection bounced slightly in front of him.

"Well, well, well, what to do first?" he asked in a teasing, confident voice.

Hannah raised an eyebrow. "You missed the sock lecture, huh?" she said. "Here's your punishment. Go there," she pointed to a chair. "Sit down. Hold on to the chair seat. No touchie, not us, not yourself. And most important, shut up."

Heather laughed. "Nice doggie," she said. "Sit."

Taylor shook her head and growled, but didn't veto the others.

Zack walked over, sat down, and grabbed the chair seat. His erection throbbed up from between his legs.

Hannah said, "Good boy. We'll let you know when we want you. Okay Heather, back to work. Ready Tay?"

For Zack it was an even worse temptation to be inside the room, without being able to touch, to say anything, to do anything. His first crush Hannah, a beautiful blonde cheerleader with lush curves, was driving a harnessed dildo into Taylor's pussy to her obvious pleasure. Hannah's bouncing boobs were amazing eye candy. Taylor's sounds and motions awakened a desire for his sister he'd never known. Meanwhile, Heather licked the keystone of Taylor's pussy, her sensitive clit. Heather kept brushing back her smooth brown hair, sneaking little teasing looks at Zack with her tongue in Taylor's puss. Taylor's own tongue was busy with Heather, Taylor's hands wrapping round Heather's hips to lift her head up to Heather's vulva.

****. Zack's fingernails dug into the bottom of the chair seat.
