Marinette was talking into her phone... 'Tomorrow is my birthday...or to be exact at midnight which is...whoa only twenty seconds away. Well, they probably got their 'surprise party' planned am going to catch some Z's. Bye now.' she said as she hung up her phone. She looked at her phone. 'Five, four, three, two, one..."
Adrien fell down on her bed, apparently having come out of nowhere. "Adrien, what are you doing here?"
"I don't know." Adrien asked.
"I know what we are going to do." Kagami said, having seemingly appeared out of thin air next to her bed.
"Gah! Kagami, how did..."
"I know what, or rather whom, we are going to do. You, Marinette. All three are of legal age now, so...off with those pants!" Kagami said.
"Oh my god, what do we do?" Adrien asked.
"We could remove her pants!" Kagami answered.
"She has fainted, she is not having any problems with her digestion." Adrien reminded her.
"Oh? She has fainted? I thought she presented herself." Kagami said. "How did she faint again?"
"Jagged Stone, Clara Nightingale and a couple other celebrities are presenting her with the biggest opportunity ever, she passed out in bliss." Adrien said.
"I am much better at that." Kagami said.
"Giving her opportunities?" Adrien asked.
"No, making her pass out in bliss." Kagami answered.
"I am awake..." Marinette grumbled. "Kagami can still remove my pants if she wants."
"Yes!" Kagami said as she pumped her fist.
Marinette was playing video games with Kagami and Adrien. First it was Ultra Mecha Strike. Marinette looked bored as she with one hand worked the controls and looked in a fashion magazine with the next. She was still kicking their asses. "Ok, this is not going to work. Hey, Mari! Let's play Pokémon!" Adrien asked.
Five minutes later. "Oh come on! How could she beat my Dragon types with a Ladian?" Kagami noted.
"I didn't know Ladian could even learn those moves..." Adrien noted.
"You got another game where I can school you in?" Marinette asked.
"Oh, let us see you try in this racing game..." Kagami said as she pulled out another one.
"Oh, I didn't know you could take that shortcut. But you got to pull off a sick trick. Lemme try...Dang it!" that was what Adrien was saying after Marinette dominated the racing game circuit.
"Let's see if she could do the time trials in Crash 4!" Kagami said with a smirk.
Five minutes later, Marinette not only did all time trials, on the leaderboard she held the world record. "This is getting ridiculous." Adrien noted.
"You got anything else? I'm waiting...to cream you guys again." Marinette said smugly.
"Oh, I know something..." Kagami said smugly.
An hour later, a naked sweaty Marinette lay in the bed, eyes glazed, drooling and mumbling incoherently. Kagami was looking smug. "I am undefeated at 'Super Penguino'. What do you think Adrien?" She looked at her other side, but he was in a similar state as Marinette. "Oh right."
When they were all getting changed in the locker room during gym class, Alya noted something. "Er...Marinette?"
"Yes, Alya?"
You do realized your panties say 'property of Kagami Tsurugi', right?"
"Yes, Adrien has matching boxers." Marinette said, as if was the most normal thing in the world.
Alya opened her mouth a few times like a fish, unable to think of an answer. "Nope!" she finally decided upon and quickly got dressed to get out of the room as fast as possible.
The Akuma looked suprrised when Ladybug and Chat Noir came onto the scene...and promptly fell on to the floor.
"I can't feel my legs." Ladybug said.
"I can't feel anything between my legs." Chat Noir said.
"Pardon them, I tired them out. I'll do most of the fighting today." Ryuko explained.
"Man, she is just as much a nymph as Kagami." Alya said. "And she also has a blonde dorky boyfriend just like Kagami and a creative blue haired pigtail girlfriend, also like Kagami...Must mean...Japanese girls must have big libidos."
Nino facepalmed as his girlfriend totally missed the point.
"Kagami, we have visitors." Marinette said. She had been lifted over Kagami's shoulders like a potato sack, as Adrien was dragged behind her by his collar.
"We'll get back to them when we are done. You two already get started on the project, we'll come back when we're done." Kagami said as she dragged the two with her into her room.
"How repressed was she before meeting Mari and Sunshine to turn into...that?" Alya wondered.
"I dunno, but it is a good thing I have headphones." Nino said as he put them on and put the volume of his music to max, to drown out the sounds to come.
"Lucky little shit." Alya groaned as she put her fingers in her ears.
"...And that's why you have so many brothers and sisters, my dear Haruto." An older Kagami said to one of her sons.
"Goodbye childhood!" the boy said as he waved to nothing in particular.
