He chooses Karen

He'd cum in his mom twice and Amy had already given him a blowjob which meant that the one woman who had done most for him recently hadn't gotten anything for herself.

"I choose Karen," he said.

Her eyes sparkled. "Really?"

"Of course."

Then color me gone." She slipped under the booth and, moments later, he felt her fingers at his zipper.

He went ahead and unzipped for her, then dragged out his semi-stiffy.

He'd cum four times already since school but Karen seemed intent on making sure he didn't fall short the fourth time. She stuffed his dick down her throat and went at it for all she was worth.

"I don't think I'm ready for this," his mom said.

"Nobody is making anyone do anything," he reminded her. "Amy volunteered and if Karen hadn't wanted to suck me, all she needed to do was keep her mouth shut."

"Of course she wants to. You're a very handsome young man and, frankly, it's hot that so many girls are into you. Hot for her as well as for me. But she's your sister."

"Mom, that just makes it hotter."

"Oh."

"You're a good girl." He patted Karen's head. "Good girls get treats."

"Uh, Matt," Amy said. Your cum doesn't taste that good."

"Well, that's the treat she's getting anyway."

April showed up with the pizza, looked around and said, "Oh, do you want me to hold this until your sister gets back."

"She'll be fine," Matt said.

"Okay. And Matt... if you want to stop by for a minute after dinner, I have something I'd like to show you."

"If it's not something I've already seen, I'm definitely in for it."

She turned around and hiked up her skirt... showing the thong she wore and a pretty spectacular ass.

Matt came into his sister's mouth. "Nice," he said.

"Glad you like it," April replied.

Under the table, Karen giggled.
