They rise up, and Derrick gets two naked ladies for the price of one

"Psst, hey!" Derrick whispered to Jessica as he brushed the back of her elbow to turn back to him.

"What?" Jessica whispered quite angrily at the boy, who knew her name by some machinations she still didn't understand.

"There's two of us and one of her," he pointed discreetly at Grace.

"What do you mean?" Jessica looked quizzical.

"Let's take her clothes off unless she lets us continue our fun," Derrick explained with a grin.

"But I don't want this 'fun'!" Jessica protested as Grace became suspicious of the conspiratorial group.

"I'll make sure she ungrounds you," Derrick continued.

"Ugh, fine, but you have to take the hit if we get into even more trouble!" Jessica acquiesced as Derrick simply nodded his acceptance of that risk.

"Just go behind her, hold her hands, and I'll take care of the rest," Derrick explained as the two teens accosted Grace and Jessica walked behind and held her hands in place.

"What is this? Jessica, unhand me at once!" Grace commanded her daughter. Her attention soon turned to Derrick, however, who quickly put his thumb in the waistband of her black miniskirt and pulled down. After fumbling around with getting Grace's skirt and heels unwrapped from her feet (and all too briefly rubbing up against them with his hands), Derrick rose up to Grace's black lace thong and pulled that down as well, dropping it into the pile with the skirt and heels.

"This is inappropriate and unacceptable behavior, young man!" Grace simply scolded Derrick without seeming to care all that much about what was happening with her attire.

Next came Grace's pullover blouse, which was soon pulled up to her armpits as Derrick rid Grace of her black bra. Gesturing for Jessica to raise Grace's arms, Derrick pulled the blouse up and over Grace's head, plopping it down on the pile with the rest of her clothes as Jessica let go of her.

"You see what I mean, Jessica?" Grace turned to her daughter, "This boy is a bad influence on you!"

"Mom, you're naked!" Jessica stated the obvious as Grace made no effort whatsoever to cover up. Derrick was for his part immobilized by the sight of Jessica's MILF mom, her early-to-mid 40's body perfectly tanned in all but the thong area - even the breasts! - and perfectly complementing her cougar physique devoid of all but the most minor and universal wrinkles. She was a early middle-aged version of Jessica, but no less hot, maybe even hotter as her energy contrasted with Jessica's timidity.

"Whatever, I was naked when you were born, and so were you!" Grace brushed that aside, "I'm just saying your 'secret boyfriend' is leading you down the wrong path, and you need to get rid of him."

Jessica debated whether to clarify to her mother that this boy wasn't really her "boyfriend" after all. Derrick started to feel really guilty about this whole exercise, and wanted to prove himself worthy of joining Jessica's family. On the other hand, Jessica and Grace were sights that really needed to go on his camera roll, if only he could pull his phone out without them seeing.

"Mrs. ..." Derrick knew Jessica's name from her phone, but never did find her last name.

"[Jones/Lutz/Jurasek/insert non-canonical last name here]," Grace clarified.

"I didn't know about any of Jessica's school that she was supposed to be at," Derrick told a half-truth before continuing, "but if you let me and Jessica keep going, and don't tell my parents, and unground Jessica, I'll let you two get dressed, and let Jessica go to school and we can continue on as normal. I can even come to dinner at some point!"

Grace considered the offer pensively as Derrick realized the risk he was bearing.
