Why not?

"I don't think there's anything wrong, mom," Matt said. He brought his hand to his mother's head and gently turned it and tilted it down so she could see into the gap between the booth seats and the table... where Karen's blond head was bobbing over his dick.

"Oh." He couldn't tell if she was intrigued, upset, or just so overwhelmed by the past few days that she couldn't deal with it.

"What is it?" Eliza asked.

"Probably my phone," Matt lied. "I've got a weird ringtone. Don't worry, it'll roll over."

"Maybe I can help with that," his mom said. She reached under the table, grabbed Karen's head, and shoved it hard down on his cock.

"Yeah, thanks."

"Just doing my job."

He wondered. She'd seemed a little overly aggressive in shoving her son's cock down her daughter's throat. Almost as if she were either jealous or perhaps pissed at Karen for dominating her and ordering her around. Matt wasn't interested in having conflict in his household but he certainly wasn't going to complain about having his sister's tonsils around his dick.

Her mom kept Karen's head pressed down until Matt finally exploded down his sister's throat.

"This is the best pizza," Amy announced.

"Oh, yes," Matt's mom agreed. "Too bad Karen is missing it." She finally let go of Karen's head and Matt's sister pulled away from Matt's dick coughing and gagging as quietly as she could.

"I'll create a diversion," Amy whispered. "Karen, you'll know it when it happens. Wait until then to go back to your seat." She hopped up and headed toward the kitchen.

Karen nodded, then nuzzled against Matt's crotch, her soft cheek rubbing on his cum-covered dick.

He handed her a napkin but she instead dried his dick off with her long hair.

A few minutes later, Amy and April appeared with a cake inscribed, "Happy V-Day."

"It really isn't valentine's day," April said. "But Amy insisted."

Amy made a big deal about finding a knife to cut the cake, getting new plates, and... when Eliza was distracted, Karen popped back into her seat... just in time to get a piece of cake.
