A/N : And you'd think they would behave better after having kids. Or even actually wearing underwear during their kid's show and tell session. But noooo. Then again, that's our AdDek. This is by Allie (evilmistress007). Have fun!

Addison and Derek had taken the night off to attend their son's school Family Night. It was a night of food, fun and games. But first, they had to sit through endless moments of kindergarteners showing off their pictures, stories, and pieces of art. Addie had her son on her lap, while Derek sat there impatiently, lightly tapping his fingers on the tiny desks. "This seat is hurting my ass" Derek complained silently to his wife, pointing at his plastic red chair

"It's meant for 5 year olds... not people over 40" Addie replied with a laugh "It's over soon... he's next. Right Matty?" she smiled as she ruffled her son's hair. It was thick and plentiful, compared to the thin, uninteresting hair of his classmates. At first glace, you had to admit, the kid had a hair full of gorgeous hair. With parents like those, who wouldn't?

"Good luck buddy" Derek gave him a pat on the shoulder as he walked up to the front of the classroom.

Matt was nervously reading his own version of 'The Three Little Pigs'. His proud parents gleamed with delight as his voice echoed through the room. "And in the end... everyone died, including the wolf" he concluded with a grin

Addison flinched "What the hell have you been teaching that kid?" she hissed

"Don't yell at me!" Derek shrugged his shoulders as Matt ran up to them

"Mommy, Daddy, what did you think?" he asked enthusiastically

"Well..." She was about to say something critical, but softened her tone "It was great sweetie"

Before Derek could say a word, Matt was already catching up with his friends and running out the door. The crowd of parents and students were headed towards the cafeteria to collect their milk and cookies.

"Guess what... we're alone" Addison said with a wink

Derek stood up and stretched "I'm going to get a cookie..." he yawned

Addison grabbed his wrist as he was about the exit "We're alone!" she emphasized. Clearly her husband was not catching her vibe.

"And... time to go"

"For Pete's sake Derek I'm not wearing any underwear!" Addison blabbered out

He stopped in his tracks "And we haven't had sex in... a while" He crept closer to his wife, placed his hand on her kidney and made his way down "Damn you're right... how can you not wear underwear?"

"Not the point. Come on, we have time, no one is going to see us" she pleaded

Derek peered his surroundings cautiously. After all, this was a school, a learning institution, not some strip club. "Fine" he said, giving in. Hornyness was getting the best of him. The next thing either of them knew, they were naked... in their son's classroom

-----------------------------------------------------
20 minutes later, happy and satisfied, the Shepherds' quickly got dressed and hurried to the cafeteria.

"Where were you?" Matt demanded, marching up to them

"We were... somewhere" Derek said hastily

"Your head is messed up..." he observed, looking at Addison's hair "What happened?"

"Well uh..." Addie tried to think quickly "Daddy and I were playing the tickle game..."

"Like this" Derek grabbed his son and wildly tickled him
