Someone comes to help

As much as she wriggled, kicked her legs, pushed against the wall with her hands, Sandry could not move her rear end through the window. She was just thinking of giving up hope, of resigning herself to the moment when someone would enter the cupboard and see a panty-clad backside hanging from the window, when she saw someone approaching around the side of the building.

It was a stunningly pretty girl, almond eyes and darkened skin hinting at Asian descent, and fortunately it was one of Sandry's friends.

"Theresa!" Sandry hissed. The girl could not have failed to see Sandry hanging like a bizarre hunting trophy, except she was engrossed in her phone.

"Theresa!" Sandry exclaimed louder, and this time her friend looked up. It took her a few seconds to realise what she was seeing, then her face broke into a broad grin.

"What on earth are you doing?!" she began to laugh.

"It's a long story." Sandry said, "But I'm stuck... Hey!" she realised Theresa was taking a photo of her, "Help me!"

"Sorry! So, what, you want me to pull you?"

"Yes!"

"Should we, I don't know, grease you up or something first?"

"That depends, do you have any grease with you?"

"Well, no."

"Then please just pull me."

"Okay..." Theresa put her phone away, then took both of Sandry's hands in hers. She stepped close to the wall, lifted one foot up to brace herself.

There was a short, violent tearing noise and Theresa let go, stepping back and twisting her body round.

"What are you doing?" Sandry exclaimed.

"I split my trousers." Theresa explained, pouting.

"I'm very sorry for you, but I'm stuck in a window half-naked, so would you mind terribly if we dealt with by problem first?!" Sandry struggled not to raise her voice and draw any attention from the class behind her.

"Right, sorry." Theresa took hold of Sandry again, braced her foot again, and pulled.

For what seemed like ages they stayed like that, Theresa pulling and Sandry wedged like a cork in a bottle. And then suddenly, she realised she was moving.

"It's working!"

Sandry became aware of two things, both of which worried her immensely. The first was that her backside, as it emerged into the open air, was bare, her panties snagging somewhere on the way. The second was the sound of a door opening behind her.

She heard the sound of commotion from the classroom but then she was free, falling through the window, only just having the sense to hook her foot around her knickers as she tumbled out of the window and landed on top of Theresa.

"You did it!" she gasped, rolling off her friend.

"What happened to you?" Theresa exclaimed, looking down at her. Sandry's blouse had not survived the ordeal, and somewhere along the way her tie had also been torn off, leaving her in a skin-tone bra, white socks, and a pair of panties which she pulled up to find the elastic had snapped. She held them up, but they still drooped at the back.

"Believe it or not, I went into that classroom to fix one hole in my clothes."

"We'd better see if we can get something else to wear."

"Exactly what I was thinking." Sandry let Theresa lead the way, she was much better to encounter anyone that might be on their way. Which gave Sandry a view of Theresa's rear, the back seam torn completely open and revealing a lot of bare skin.
