Their mother.

“I realize you two are newlyweds, but could you refrain from having intercourse in the public spaces of the house.” Serra said with an exasperated sigh. Serra felt her pussy grow a little wet as she looked at her son and she mentally chastised herself. Her eyes found his cock and she bit her lip in frustration as a few lewd thoughts entered her mind.

Matt noticed his mother staring at his dick and covering himself with his hands said. “Sorry about that. I’ll go get dressed.” Matt got up and headed for his room.

Lisa turned and looked at her mother with an angry scowl and asked. “Why do you have to be such a prude?”

Serra looked hurt as she said. “I’m not a prude. You are not the only one living here. What if your sisters had found you like that?”

“Oh please. Becca and Ann are the biggest slut’s in town.” Lisa said causing her mother’s mouth to fall open in shock. “And don’t think I didn’t notice you eyeballing Matt’s dick.” She finished making her mother turn a deep shade of red.

“Please don’t fight.” Matt said as he turned to look at both of them. His mother and sister glared at him making him regret he had said anything. Matt looked at the pen in his hand and thought about using it to fix the situation.
