Of course he does, what choice does he have?

Sam looked at his watch. Ten past eight. He'd holed himself up in his room since half six, feeling terrified at the prospect of what John had in store for Ellie tonight. Whatever degrading and humiliating way she was going to be used Sam knew he had **** but to watch. Twenty minutes ago he had heard John and Ellie come home, but he waited for the signal to come out.

Suddenly he heard a knock at the front door, followed several seconds by his phone buzzing. The message simply read "Come out, it's show time"

Carefully Sam opened his bedroom door and quietly edged out into the hallway. Hiding in the shadows he could look down into the lounge without being seen. Ellie stood with her back to him, wearing a denim miniskirt and her pink crop top which simultaneously made her look young and innocent whilst showing off enough cleavage to show that she wasn't. As he perved on his sister's figure he noticed that over her long blond hair was a blindfold.

John came through the doorway, looking up very briefly to make sure Sam was watching, and to make sure Sam knew his presence had been noted. behind him came another man.... a man Sam suddenly recognised. Mr Willis had been his English teacher at school, fresh from teacher college. At first Mr Willis had seemed a reasonable figure, which is why when John's bullying picked up Mr Willis had been the teacher Sam had gone to. Big mistake. Mr Willis hadn't just ignored Sam's pleas for help, but he'd made out that Sam was the one in the wrong. From that point on English classes became a ritual of pain for Sam - nothing he did was right and acceptable, and often resulted in Sam being put down and humiliated in front of the entire class. And whilst Sam could try to avoid John at school, there was no hiding from his teacher.

"Are you ready for your surprise?" asked John. Ellie nodded, promoting him to remove the blindfold

"OH MY GOD!" exclaimed Ellie "when I asked you to invite a friend round for some fun I didn't dream it would be favourite high school teacher! How do you guys know each other?"

Sam's heart sunk. Not only was Ellie pleased to see Mr Willis but he had an awful feeling he knew what fun he'd be having.

"Our families go way back. I helped John out when he was at school, and he promised me one day he'd return the favour. I didn't realise at the time that would mean with the hottest student I've ever taught"

"I used to love your classes Mr Willis. I would always sit in the font row because I loved it when you tried to secretly check me out. I'd always wear low cut tops to your classes so that you'd stare at them at my breasts. Did you enjoy the view?" Ellie slowly inched closer to him as she talked.

"Oh fuck yes. I'd go home each night and jack off thinking about you"

"I was such a naughty, naughty student wasn't I Mr Willis? Getting my teacher all hot and bothered when he was trying to work" Ellie flashed her widest grin at him "now how should I say sorry.... hmmmm..... how about I let you see what I had to keep covered up in class?"

And without waiting for a response Ellie lifted up her top. Mr Willis barely had time to focus on her black bra before Ellie had it unfastened and thrown to the floor.

"I always fantasised about flashing you in class", Ellie revealed, her breasts bouncing gently as she stood invitingly before him "What do you think Mr Willis. Are they as nice as you imagined?"

"Oh they are perfect" he replied

"Maybe you'd like a closer look" said Ellie as she moved closer, her pert breasts almost pushing against his chest. As she got within touching distance she reached out and started stroking his crotch. "Oh Mr Willis, does your cock get this hard for all your students?" Any doubts Sam had about what was about to happen were quickly evaporating.

"Only the really slutty ones"

"Well how's about this for a deal. I'll let you play with my breasts if I can play with your dick"

Mr Willis didn't need to be asked twice as he reached out and grabbed her plump breasts. Ellie meanwhile undid his jeans and pulled them down and before wrapping her hand around his erect penis. Sam was horrified that it had taken less than two minutes for Mr Willis his hands all over Ellie's tits whilst she jerked him off.

"Oh Mr Willis, you have such a nice dick" cooed Ellie "All the girls at school used to guess which of the teachers were the most endowed. I always picked you, because I liked to imagine you had a big cock. I was so right"

"And your tits just feel amazing" Mr Willis replied as he teased Ellie's nipples

"I bet they'd feel even more amazing if they were wrapped around your cock. Would you like that Mr Willis, would you like to have your student's breasts around your dick?"

"You wouldn't believe how many classes I wasted thinking about that" replied Mr Willis, grinning from ear to ear.

Ellie turned to John, somehow managing to look sweet and innocent despite having her naked breasts fondled as she administered a handjob to her former teacher. "Is it okay if I let nice Mr Willis fuck my tits?"
