An Offer Steve Can't Refuse

Steve, Gwen and Francine made their way back to the dorm rooms. Gwen was busy looking around for a quite place. She spotted what looks like an empty classroom. She looked inside and saw it was empty, then she grabbed the back of Steve's blazer and pulled him inside. Francine just sighed and followed.

"Locked the door." Said Gwen, Francine nodded.

"What's....." Said Steve, but was cut off.

Gwen smirked, the pulled Steve into a kiss. Steve's eyes went wide as years of fantasies flooded his mind. Gwen rammed her tongue into his mouth, soon the pair was making out.

Francine watched with a mix of embarrassment and curiosity. She started rubbing her thighs together as she herself was getting aroused. Gwen wrapped her leg around Steve, as his hands went up her skirt. One hand caresses her thigh and the other squeezed her ass. Gwen moaned as she knew her plan was working. She knew both Steve and Stan lusted after her.

Soon Steve decided to be bold for once. He slowly maneuvered Gwen and him over to the teacher's desk. Then he pushed Gwen backwards onto it.

"So what's your plan ?" Asked Steve, as he crawled on top of Gwen.

Francine watched as she started licking her lips. She was getting watching this incestuous affair happening in front of her. Her pussy was getting wet as she slowly walked over.

"Good boy, you're a lot brighter then your father." Said Gwen, smirking. She started undoing her tie and unbuttoning her blouse.

Francine couldn't help herself, as she slowly moved one of her hands up skirt and down her panties.

"I will get to the point, I will have casual sex with you. If you promise not to sell me out." Said Gwen, as she exposed her strapless red lace bra. Steven grinned, as he felt his cock twitched.

"I wasn't going to." Said Steve, as he was telling the truth.

"I guess as much but I want to make sure." Said Gwen, getting up from the desk. She unzipped her skirt, letting it fall to the floor. Steve locked his lips as he looked at her matching thong.

Gwen got onto her knees and started undoing Steve's pants. Both Gwen and Francine gasped as Steve's fully erect manhood flopped out. Steve looked down and saw the reaction on Gwen's face and smirked.

"You're so much bigger then your father." Said Gwen, smiling. Steve grinned and then back to his mother. She gulped, as she knew what Steve wanted to hear.

"Gwen rights, you're three times bigger then Stan." Said Francine, Steve grinned.

Gwen got to work, she started to give Steve a blowjob. Steve let out a moan as he placed his hands on her head. Francine couldn't help it and started undressing as she continued to finger herself.

Steve was in heaven, he wanted Gwen for so long and was now finally getting it. The fact his father wanted Gwen too but he got her first was making it even more sweeter. The cherry on top was the fact he was so much bigger then his father. After a few minutes Steve couldn't hold and climaxed. Gwen easily swallow his load.
