The way back
Elin's face was flaming red. She felt she had been caught out. With an uncertain smile on her face, she stood on her own two feet. Her legs trembled with excitement and embarrassment.
"You look really cute, Elin!" Paul looked at his teacher, slowly scrutinising her from her wriggling toes to her tousled hair. He nudged Sylvia's fiancé with his elbow. "Right?"
"Oh, so late already! We'll have to fix the hair up there on our head. - Paul, you have to take your teacher to us and the charity party on the underground!"
"Yes, we have to get to the next appointment. We'll take the new clothes with us in our car!" said Eugen.
Sylvia handed Elin Paul's T-shirt and a pair of sandals that looked Greco-Roman, like in the sandal films of the 1950s. Then she grabbed several shopping bags, presumably containing Elin's new clothes, and walked quickly with Eugen to the lift.
"Well, I'll take you back to my place." Paul waited until Elin had put on his T-shirt and sandals, grabbed her hand and pulled her along.
Elin waved goodbye to the hairdresser and then used her free hand to pull down the T-shirt, which had slipped back up.
On the way to the lift, the teacher fought a hopeless battle with the T-shirt to at least cover her mons veneris. Although she was now wearing shoes and no longer felt the carpet under the soles of her bare feet, she still felt naked.
"Not so fast, Paul! My T-shirt is riding up!" Elin pleaded and tried to stop him by pulling on his hand.
"Yes, yes ... Don't be so stubborn now! We have to hurry!" Paul spoke to Elin like a small child.
"But I don't want to travel half-naked on the underground!" Elin replied defiantly.
Paul stopped abruptly in front of a cash desk where some people were queuing to pay for their new shoes.
Elin ran into Paul because she hadn't expected to stop Paul.
Paul sat down on a bench that was used to try on new shoes, pulled Elin towards him and put her over his knees.
Elin didn't know what was happening to her and only realised what was happening when she felt Paul's blows on her bare bottom.
Elin was so surprised that she didn't even cry out in pain, even though Paul hit her very hard. It was only when the fourth blow landed on her buttocks that she said "Ouch!".
"You're not going to slow me down, Elin! We're in a real hurry!" Paul sounded angry.
Elin was intimidated by the pain, the humiliating position on Paul's knees and by his anger. She wriggled her legs, but did nothing to protect her bottom from his blows or to get away from him.
"Forgive - ouch - me - ouch - Paul! I - ouch - will - ouch - follow - ouch - you!" Then she began to cry and her tears ran down her face and dripped from her nose onto the carpeted floor of the KaDeWe.
Paul hit her four more times, then stroked her face and her now bright red bum.
Elin sobbed, Paul helped her up and sat her next to him on the bench, hugging her.
"Oh Elin, I don't want to hurt you, but if you don't listen, then that's the way it has to be!" Paul spoke in a soft, soothing voice.
Elin leant against Paul, sobbed and nodded her head sympathetically against his chest. She was happy that Paul was no longer angry with her. She really had behaved childishly.
"I'm sorry, Paul! Forgive me!" she said, sobbing and looking up from his chest to his face.
"It's all right now ... Now your face and your cunt are all wet ..."
Elin smiled and nodded.
"I'd rather be wet underneath ..." she said in a whisper and gently stroked Paul's chest.
"I know! Well, come on! We have to get going!"
Paul stood up, Elin followed him and looked in shock at the people at the cash desk, who were open-mouthed in amazement at what they were seeing.
Elin's face turned as red as her bottom and she looked down in shame.
Paul pulled her along to the lift.
Elin now ran quickly after him, no longer caring whether the T-shirt really covered everything.
Paul called the lift and the cabin door opened after a few seconds. Two old ladies stood in the cabin and after a second stared in shock at Elin's uncovered mound of Venus.
"Young man! Your ... girlfriend there, she's naked!" said one of the old ladies indignantly to Paul. Her face showed even more anger than her voice.
"Yes, I know. It's part of a ... um ... experiment. We want to find out whether there are still moral citizens who denounce inappropriate behaviour. You are the first! Congratulations, Mistress Fleusen!"
The old ladies' faces brightened.
"Ah, very good! Our Western community of values is on the verge of collapse! It's good that there are still young people like you who want to save the Christian West!" said one of the two old ladies.
"Yes, but perhaps you should be even more provocative! Why don't you push up your shirt?" While the other old lady was still talking, she pushed Paul's T-shirt up Elin's body so that the hem was above his navel.
Elin allowed the old lady to expose her further without resistance. She looked at Paul, who smiled as he watched the old lady roll up the fabric on Elin's hips and stomach.
The lift door opened with a "Pling!" and Paul led Elin out into the reception hall, where many people were crowded and only noticed Elin in passing. Only a few of the department store's customers smiled at the sight of the practically naked woman, who let herself be led through the crowd by her pupil's hand. Several hands touched Elin's bare skin on her bum, mons veneris and legs. Elin reacted with a startled and excited deep breath. She carefully grabbed the hem of the T-shirt with her hands and pulled the fabric down.
A painful slap landed on Elin's bum. Paul stopped.
"You heard the two ladies! Don't you dare pull your T-shirt down! You're going to push it up again, understand?" Paul snapped at her and, startled, Elin obeyed his order and pushed the hem of the T-shirt back up over her belly button.
"But I can understand why you're worried." He pulled her towards a jewellery stall. A smiling saleswoman stood behind the glass sales counter.
"A belly chain please," said Paul.
"Ah, yes! I see! - Here are these." The saleswoman placed a gold-coloured metal chain on the counter. "Twice around the stomach and with a pearl appliqué as a hanger. It looks very sexy and goes well with your friend's clean-shaven pubic area, Mr Hackenreuther."
Elin was surprised. They knew Paul here!
"Yes ... that will fit." The student put the necklace around his teacher's belly and positioned the pearl pendant over her vulva.
"Oh, yes! Very nice! - That's almost an engagement ring!" The shop assistant clapped her hands enthusiastically. "Well, if my boyfriend gave me this as a present, I'd say yes straight away!"
Elin understood less and less what was happening. She couldn't let Paul marry her!
"I'll put that on the family bill, Mr Hackenreuther!" said the shop assistant in a rather business-like tone.
Paul nodded in agreement and then pulled Elin along with him. She still felt naked despite the belly chain.
At last they reached the large doors at the exit and pushed their way out onto the street, which was at least as full of people as the department stores'. A huge storm of people passed them and pulled them along towards Wittenbergplatz underground station.
Only a few people noticed that she was naked underneath and that the belly chain rather drew attention to her vulva, but the few glances and the few grins were enough to make her feel deeply ashamed.
"Paul ... please ... I'm naked ..." she begged, not really knowing why she was doing it. Because how could Paul help her? He certainly wouldn't take off a piece of clothing to give it to her.
"Yes, that's why I'm going to the underground with you!" he replied.
(U-Bahnhof Wittenbergplatz)
The walk up the stairs from the entrance to the underground platform had never seemed so long. Many people looked at her with amusement, some pointing their fingers at her naked, hairless vulva. Elin closed her eyes because she could no longer bear this humiliation.
Paul didn't mind Elin showing her genitals to everyone in the underground station. He enjoyed holding the half-naked woman by the hand, showing that this beautiful woman belonged to him. He noticed the envious looks from the other men and some of the women with great satisfaction.
While they waited for the underground, Paul stood behind Elin, hugging her from behind, but making sure that her bare stomach and naked abdomen were clearly visible.
Elin kept her eyes closed and hung her head so that her face couldn't be seen.
"Paul! Please! Stand in front of me! All can see my ... labia, my clitoris ... I'm ashamed!" she whispered.
Paul pretended not to be able to hear in the noise of the underground station, looked at her questioningly and shrugged his shoulders.
Elin felt the breeze from the approaching underground train on her skin. She felt even more naked. This surprised her, made her feel even more ashamed and - aroused her!
The underground stopped, people pushed and shoved their way past Elin. She felt the fabric of the trousers and jumpers on her bare skin.
Paul then pushed Elin into the crowded underground carriage. Elin felt the textiles of the passengers on her naked skin again. Paul pushed her to the row of seats where the passengers sat facing the centre of the carriage.
Elin stood in front of a bench seat and held on to the grab handle with both hands. Her T-shirt now slipped up even higher, exposing part of her breasts. Paul hugged her from behind. His hands closed over her navel.
"Hello, Mrs Stegmann!" Elin heard a girl's voice say. Elin looked down and saw Simone sitting on the bench in front of her. She was holding Enrico's hand.
"Hello ... Simone ..." Elin stammered. Following an impulse of fear, she wanted to push Paul's hands away from her so that Simone wouldn't realise that she and Paul were a couple.
But she wondered what sense that would make.
She was naked, her pubic area was clean-shaven, her labia were moist and her clitoris was protruding from her glans. And she was standing in a packed underground train.
Now she didn't care anymore. Somehow.
"You've got a nice pearl over your labia, Mrs Stegmann." Simone grinned and took the pearl between her fingers.
"Yeah, cool, isn't it?" Paul said proudly and rested his head on Elin's shoulder.
"We're off to see you now! We're helping Sylvia with the charity reception." Enrico looked at Elin's clitoris, which was the second pearl protruding from her glans.
Paul stroked his hands from Elin's stomach to her pelvic bones.
"She feels really great!" said Paul and stroked over Elin's skin, under the belly chain, over her loins to her mound of Venus.
Simone let go of the pearl necklace.
"You're the mannequin today, Sylvia told me. We'll help you change later. You won't have to undress much!" Simone laughed.
Elin felt incredibly humiliated. Paul bragged about her and her pupil Simone made fun of her teacher.
"Um, yes, Simone ... we're ... um ... doing an experiment," Elin said, stammering. She turned her head to Paul and whispered pleadingly: "Why don't you help me?"
"Yes, we're doing something like that. The Matschik and the Fleusen suggested it. It's kind of about morals. We'll see if anyone is morally outraged if you expose yourself in public," explained Paul.
"Well, a few days after the Love Parade, that doesn't shock anyone," said Simone, sounding disappointed. "You have to offer a bit more than that. - Why don't you stick your finger in and finger her until she moans?"
"Simone! I'm your teacher!" Elin replied indignantly.
Paul's hands pushed deeper and quickly reached Elin's wet labia.
"Paul!" cried Elin, startled.
Several passengers now looked at her.
The train stopped. People pushed past Paul and Elin. They ignored what was happening to the four of them. Only one woman raised her eyebrows briefly and smiled.
When the train started up again, Elin's knees swayed in time with the movements of Paul's fingers. Her breath was coming faster and faster, her eyes were closed.
"Wow! She's really going for it!" Enrico marvelled.
Simone smiled knowingly as she sensed that Elin's climax was imminent.
The underground train squealed as it rounded a bend. Whimpering and trembling with pleasure, an intense orgasm rushed through Elin's body.
No one in the underground was bothered.
The climax subsided and Elin came back to her senses. Paul's fingers slipped out of her, pulling several strings of vaginal secretions with them.
Elin didn't dare open her eyes again. The humiliation was too great. Her pupils had literally seen her experience an orgasm that another pupil had given her.
She couldn't sink any lower.
Paul wiped his wet, slimy hand dry on Elin's loins, leaving wet patches there.
Simone was speechless and looked at Elin's face, which was red with exertion and covered in sweat.
"Cool!" said Enrico.
"I don't think our experiment is working," said Paul disappointedly.
"Nobody cares if someone is naked and being fingered," added Simone. "Maybe you need to fuck Mrs Stegmann," she suggested.
Elin opened her eyes, turned to Paul and pleaded: "No, please don't, Paul! You ... you can't do that!"
"Yes, I know: nobody is allowed to know that, mimimi ... but why not? If you really love me, then you won't care about anything else! You've said time and time again that you love me! Then why don't you show it properly?" He turned his face to hers and kissed her.
She opened her mouth a little and his tongue slipped into her mouth. She closed her eyes and kissed him.
Simone and Enrico opened their eyes wider! They looked at Mrs Stegmann and Paul in disbelief.
Paul's hands stroked Mrs Stegmann's body tenderly, reached her labia and again a finger dipped inside her, but it only stayed there for a moment. Paul turned Elin around like a doll, she grabbed the pole with her hands so that Mrs Stegmann's bottom was now close to Simone's face.
Paul opened his trousers and Simone saw from behind through Mrs Stegmann's wide-spread thighs how Paul's erect member pushed into her love hole.
"Please ... Paul ... don't ...", Elin whispered, stammering, but her body said: "Take me!" and Simone saw Mrs Stegmann's abdomen willingly slide onto Paul's member, her legs gripping his body and pressing it against her.
Elin was hanging on to the handrail, Paul thrust into her, Elin moaned and the other passengers looked on bored.
The underground train stopped. Elin reached her climax and Paul moved on, bumping into an old woman who pushed past him towards the door.
"Gosh! Watch out! You can't just fuck in here like that! Why don't you sit down? You're right in the way!" the woman scolded and walked on.
Elin let Paul push her to a second orgasm while the underground started up again.
