"I'm a naughty step-mom"

Jim couldn't believe it. His heart thumped, and it felt like all the blood from that thumping heart gushed to his stiff cock.

It was hidden by her sheets, but the furiousness with which his step-mom rubbed herself, was undeniable. And the things she said to herself were amazing, "I'm so bad... I'm so naughty... I'm a naughty step mom... I'm a filthy slut..."

There was absolutely no way he couldn't squeeze his cock and tug at it hard in the presence of this insane depravity. How was this real life? He wondered.

After a few minutes, he also wondered how it was possible that Tessa didn't notice him there. He crept closer and closer. Was it possible that she was so lost in the throes of her own pleasure that she didn't sense him almost upon her.

"I'm so naughty... I'm so dirty... I can't help it... that's what step-moms do... I need to be stopped... I don't want to be stopped... I need to be punished."

This was his opening, Jim thought, but he couldn't believe he was actually going to say something and make his presence known. But what else could he do? He wasn't going to sneak back out of the room. He was too deep into this moment. Real life suddenly resembled a porno and he had to rise to the occasion. He opened his mouth to say something dirty like, "I'll punish you."

But real life wasn't a porno and his voice gave out on him. "I'll punnnn." His breath caught in his throat and Tessa's eyes flicked open.

"FUCK!" She said

And then Jim's legs gave out. He went to run again, but tripped over himself, twisting his ankle, and plopped on his ass on the floor.

"Wait!" Tessa called at him. "Wait! I didn't mean it like that."

Jim had **** but to wait. His ankle throbbed and he was fairly sure he would look very dopey trying to stand up on it and wincing and groaning in front of Tessa just now. So he sat and tried to cover for himself. "Look, I'm sorry. I shouldn't have..."

"No." Tessa sat up in bed, pulling the sheets up over her wonderful tits. But there was really no point to it. Jim had them etched in his mind forever. "This is my fault. This is truly my fault. You see, I've been trying to get caught." Jim was surprised, but then again, not really. Tessa continued. "I've been playing with myself by the pool every morning. But you kept getting up late. And this... this is exactly what it looks like."

Jim was confused. "But then why didn't you...."

"Tell you the truth?" Tessa finished his sentence.

Sure, Jim thought, or why didn't you just fucking jump me. I'd have been up for it.

"I chickened out." Tessa said. "The moment came and I got scared about what I might be capable of. You don't understand how fucked up my mind is."

"It is?"

Tessa lowered her head, her great messy blonde hair falling in her face, as if she were ashamed. "I think things that can't be unthought. I've done things that can't be undone."

Jim's boner was curious, confused, and as thick as ever. "Please, tell me." He said being some combination of supportive and perverted.

"I... shoudln't."

"Look." Jim found himself surprisingly assertive. "You've been messing with me all week. You owe me an explanation of some sort."

And to his surprise, Tessa nodded. Then slid off the bed, still covered by the covers, and sat next to him. Jim's heart pounded being this close to her. But he told himself to play it cool.

"I'm going to tell you a story, okay?" She said.

"Okay." He answered. Thinking a story might give his erection time to calm down. He didn't realize how mistaken he was.
