Orgasm denial

Josh put his clothes on and headed up to Sarah's room on the second floor. She spent the majority of her time after school in there just reading her numerous book series about magic and talking animals. It was strange seeing her so engrossed in literature, but still flunk exams to look cool and walk around naked in High-school+.

He opened the door and saw her lying prone on her bed facing away from him and reading a book. Sarah was completely naked from head to toe. Of course it didn't take much since her uniform was little more than a strip of fabric and shoes. She didn't notice Josh yet.

Josh pulled out his phone and quickly entered in a fun rule change.

• Students failing High-school+ keep a chest full of sex toys to be used on themselves as a means of punishment.

Josh hit enter and looked at the box that suddenly appeared under Sarah's bed. He felt like he knew exactly what was in the box even though he had just made the change. Dildos, vibrators, a few different kinds of gags, handcuffs, and much more. He was going to have so much fun with Sarah.

He snuck into her room as quietly as he could. Not a single noise was made to notify Sarah of his presence. He opened the chest and pulled out the handcuffs and ball gag. The toys made a bit of noise and Sarah turned around.

Josh jumped on top of her. He took her hands and handcuffed them behind her back.

"What are you doing, you snot rag?" She never was one for good insults.

"Mom wants me to help you study, so your mine now," Josh's cock grew hard in his pants, but he knew he had to resist taking it out in order to punish Sarah like his mom wanted. "Now, open your mouth like a good slut."

"You can't make me do anything."

With that, Josh picked up his sister and flipped her so she'd lay down on her back. He straddled her between his legs and gripped her throat.

"I'll give you a good reason to do as I say," He started playing with her pussy with his free hand and Sarah started opening her mouth. "That's a good girl." He stuck the ball gag in her mouth and secured the strap behind her head. He slapped her cheek and left a red mark.

Josh stepped off her and pulled another device from the chest. It was a stainless steel bar with straps on both ends for the victim's ankles. Josh used it on his sister so she could no longer close her legs off to him. Her pussy was his for now.

Josh took out a vibrator and played with his sister a bit before turning it on and bring her close to orgasm. He knew exactly when to stop and start masturbating judging by her muffled moans.

After three rounds of almost letting her cum, Josh started demanding that Sarah beg to let him. She tried, but Josh only made fun of how hard it was to understand her with the ball gag and he'd bring her close again.

After ten tries, Sarah had tears running down her face and she tried rubbing Josh through his pants with her hands still cuffed. It was sexy and thrilling for Josh.

"I finally figured it out. If I take the ball gag off, I can understand you." Josh joked and removed the gag. "Try asking me one more time."

"Please let me cum big brother. Please. I'll do anything you want. Please just let me cum." She could finally say clearly.

Josh agreed and made her cum as quickly as he could. Sarah's body convulsed from all the pent up pleasure and she screamed like a sexual banshee. The orgasm was so powerful that it looked like her body suffered aftershocks and would occasionally tense up for a couple of minutes before she could stop.

Josh put away the toys and Sarah was left alone in her room again.
