Michelle pondered her decision to spank the teens together. Over the years, they had gotten into mischief and then been punished together many times. She worried that now - as teens with maturing bodies and out-of-control hormones - she might have created or worsen the sexual tension between the two. No unringing that the bell now, she thought. Just have to deal later with any bad decisions - if they occurred.

While her mom was contemplating the unintended consequences of the paddling, Sonya lay on her bed and gently rubbed body lotion onto her seared bottom. She'd certainly have bruises that would show below bikini bottoms. Any pool time in the next few days would require something that was less revealing than her usual swimwear. She touched herself and thought about Zach. She had just checked one box in her curiosity about the male sex organ - see one, touch one, suck one, let one inside her vagina and, maybe, allow one in her ass.

Zach was in his room and while he knew relations with his first cousin were taboo, he could not unsee Sonya's shapely ass recoil from the paddling and the clear view of her pink genitalia as she wriggled and kicked. The part of his brain that engorged his penis didn't care what he saw was his cousin. The sight of a female's private areas triggered an involuntary reaction that he quickly dealt with depositing a generous load into a sock.

A few uneventful weeks went by and the pressure felt immediately after the pool party spanking faded. It was a Saturday evening and Sonya queried Michelle, "Amy's family just got Disney+ and they're having a Marvel super-hero marathon. Can Zach and I go over a watch tonight?"

"Are her parents going to be there," Michelle replied. Presence of an adult host was a strict rule.

"Of course," Sonya lied. Amy's parents were away and Amy had promised beer and boys to enhance the evening.

Zach's face suggested to Michelle that there was something afoot but she gave her permission anyhow.

Later, settled into the couch with a cold brew, Zach snuggled against Amy. He noted that Sonya was in a dark corner, entangled with Erik. When the movie ended, Zach checked the time on his phone and was shocked - it was just ten minutes until their curfew. He looked towards the corner to warn Sonya they needed to leave in order to avoid the wrath of his aunt. The corner was empty.

"Maybe they're in the guest bedroom," Amy suggested. She led the way to a closed door and giggled at the sounds of rustling and moaning coming from inside.

Sonya was enthusiastically stroking Erik as he lay on his back when she heard a soft knock on the door. "Sonya. Gotta go or we're gonna be late." Zack didn't have to add what awaited them if they were late.

"Ok. Be out in a minute," she replied. She kneaded Erik a few more times before he erupted. Most of the ejaculate landed on his own chest but Sonya squealed in surprise at the sudden release that sent a rivulet or two onto her face.

"You ok?" Zack called.

"Be right out," Sonya replied, hastily getting dressed and wiping the cum with the sleeve of her shirt.

A few minutes later they arrived home with just seconds to spare. Michelle asked, "How was the movie?"

"Cool," Zach replied.

"Meh," Sonya shrugged.

Michelle had a nose for beer and bullshit, and she smelled both. "How about you tell me the truth," she countered.

"Whaddya mean," Sonya whined.

"I texted Amy's mom to thank her for hosting the movie night. Apparently she's visiting her sister," Michelle announced. The two culprits were silent as then carefully examined the floor. "Each of you to your rooms. I need to think of what is the appropriate response to such dishonesty and deceit."

A few minutes later Zach heard voices from Sonya's room. The muted discussion was brief and then he heard a loud whack and a yelp. He wondered what Sonya had been swatted with but obviously something severely painful. His mind immediately rewound to Sonya's spanking he'd witnessed a few weeks earlier and he imagined her soft bottom recoiling with the impacts of the implement she was now receiving. He immediately went hard with that imagery in his head. He counted ten whack/yelp pairs and then silence before a knock on his door. His aunt held a large paddle like he's seen his school principal wield.

"Zack, I don't have much to say except I'm very disappointed that you two lied to me. Dishonesty carries a very severe penalty. Turn around and face your bed. Prepare yourself for a paddling then bend forward with your hands on your knees," Michelle instructed.

Zach complied and presented his bare bottom for the punishment. Michelle noted again her nephew's physical response to corporal punishment and made a mental note to have him go first in the future. She tapped the paddle against his bare cheeks and then gave him a home-run swing. He rocked forward and her second swat met his butt as he swayed back into position. After ten hard swats, Zach was sobbing and dark bruises were developing on the underside of his cheeks. "Keep that in mind, next time you consider breaking the rules," Michelle noted and left the room.
