Lily forces Monica to join in

We all looked over at the door as it opened. All of us were like deer caught in someone's headlights. In walked Monica. When she saw us, she looked like she was about to faint. But somehow she managed to turn around, and was going to head out the door. That is until Lily stopped her cold in her tracks. "Don't you dare go out that door, you mousy little bitch!" She ran and grabbed a hold of Monica's jacket collar, and pulled her backwards, making sure the door was shut, and locked.

"Please, just let me go!" Monica squealed. "I'll come back later! I swear I won't say anything about this to anyone."

"Oh, I'm not worried about that, my little mouse" Lily went on to say. "I've had my eye on you for a long time."

"W-w-what do y-you muh-mean?" Monica stuttered and stammered.

"It's the quiet ones you always have to watch out for" Lily explained. "You're quiet, you're mousy, and you'll do whatever I say. Right now you're going to take off all your clothes, and join those two on the floor. That is unless you want me to help you get undressed." She flashed the knife at Monica as reinforcement that she was serious.

"E-everything?" Monica asked.

"Everything!" Lily menaced. "I want to get a really good look at that body of yours!"

Monica's face turned bright red as she slid her jacket off, and dropped it to the floor. She stepped out of her shoes, and pulled off her socks, trying to delay the inevitable for as long as possible. She slowly unbuttoned her top and put it on top of her jacket. Her skirt was next as she unsnapped unzipped it, allowing it to fall in a heap around her feet. She was left standing there in a white bra that looked like it had been invented back in the 1940's, and a pair of white granny panties.

Lily laughed at her. "Your underwear is too much! Where did you get it? Goodwill? That's the worst looking pair of granny panties and a granny bra that I've ever seen! Get those ridiculous things off now!"

I really felt bad for Monica as she cringed and turned a darker shade of red. The poor girl actually did have a nice figure that was even noticeable with her choice of underwear. But she always wore long skirts that hid her legs and these tops and sweaters that made her look, well, boyish.

"Well, come on. I haven't got all day. Off with that bra. I want a good look at those little titties."

Monica unhooked the back of her bra, and slid it off over her arms. She immediately tried to cover her breasts with her arms and hands, but she saw Lily shaking her head no, so she dropped her arms to her sides, exposing her perky little breasts for all our eyes to see. They were, in fact, quite cute with their large, puffy aureola, topped with thick, erect nipples.

"Wow! Very cute!" commented Lily. "You have a pair of nice tits that definitely won't go to waste. You could breastfeed an army with those nipples!"

"Thu-thank you?" stuttered Monica.

"Okay, get those granny bloomers off. Let's see that cute little pussy of yours. Then turn around and show me your ass."

She pulled down her panties, and let them fall to her feet. Again her first instinct was to cover herself up, but Lily shook her head no again. She stood there as naked as the day she was born. Lily walked over to her, and felt her big, bushy mound of soft pubic hair. Then she turned Monica around to get a good look at her ass. Sure it was small, but it was also cute. The way the bottoms of her cheeks curved made her ass a nearly perfect heart shape.

Lily slapped Monica on the ass, causing her to flinch and yelp. "Okay mouse. Get over there with the other two girls, on your knees."

"could I use the bathroom first?" Monica asked in a squeaky voice.

Lily put her hands on her hips, and looked at Monica impatiently. "Number one, or number two?"

"One" came her almost inaudible answer.

"I've got a better idea. Gather up all those clothes. You can pee on them."

"Whu-what?"

"You're not a light bulb. Gather all the clothes up, and piss on them. Or else you'll just have to hold it until you piss yourself. Which is it?"
