Of course not!

No sooner had the cubicle door closed than Lukas whispered softly to me:

“I want to do this properly.” I nodded breathlessly. My body was already far too aroused to think for much longer.

We lay down in the 69 position on the soft mat. Lukas was already naked. I took a condom, rolled it slowly and carefully over a dildo so that it could be seen from the outside, and then placed it next to his hard cock so that I could use it – exactly as the demonstration required. Then I pulled a licking cloth over my labia and waited.

But Lukas did things differently. He pulled the licking cloth I’d just put on back down and set it aside. “For authenticity…,” he whispered.

Then he took my clitoris straight into his mouth – bare, without the licking cloth. His warm tongue licked me properly, sucking gently, circling intensely. I moaned loudly.

At the same time, I leaned forward and took his bare, hard cock into my mouth. I sucked him deep, sucked hard, let my tongue circle the head. I knew I was actually supposed to use the licking cloth, but the arousal was too strong. I just sucked him bare, took him deep into my throat, moved my head rhythmically up and down.

From the outside, the spectators could only see the silhouettes: two bodies in the 69 position, heads between each other’s legs, rhythmic movements, my head bobbing up and down, his tongue working between my spread legs.

To people without glasses, it looked like a harmless shadow-puppet show.

For those wearing the red glasses, it was something quite different: they saw me stark naked, my heavy breasts hanging freely down and brushing repeatedly against Lukas’s stomach, my hard nipples clearly visible. My labia were spread wide and glistening, whilst Lukas licked me properly. My head moved quickly up and down – I sucked his bare cock deep and greedily, saliva running down the shaft.

I came for the first time after a few minutes – shaking violently, whilst Lukas’ tongue sucked firmly on my clitoris. My moans were muffled because I had his cock deep in my mouth. My pussy twitched visibly against his tongue.

We carried on. Lukas licked me more and more intensely, I sucked harder and deeper. As I came, I dug my fingers into his thighs, my whole body trembled, my labia pulsed noticeably, whilst I moaned loudly around his cock.

From the outside, all you could see were two silhouettes putting on a ‘show’.

The first five minutes were pure 69. I sucked him deep and greedily, my tongue circling the glans, whilst he pushed the licking cloth aside and really licked me – his warm, wet tongue ran through my slit, sucked on my clitoris, penetrated me with the tip of his tongue. I moaned around his cock, my hips jerking automatically against his face. My saliva ran down his shaft. After just three minutes, I was so wet that it was dripping between my legs.

After five minutes, we swapped.

Lukas turned me onto my back, lay down between my legs and lifted my thighs over his shoulders. I lay exposed before him. He licked me intensely now, whilst I jerked him off with both hands and took him deep into my mouth from time to time. My breasts bounced with every thrust of my head. I came for the first time in this position – violently, trembling, my pussy visibly twitching against his tongue, a small gush of moisture running out. I moaned loudly around his cock.

We switched to the doggy position. I knelt on all fours, my bum raised high. Lukas knelt behind me and licked me from behind – his tongue ran the length of my slit, circled my arsehole, then sucked on my clitoris again. I took his cock into my mouth from below, sucking him deep, whilst my breasts hung heavily and swayed with every movement. I was so aroused that I could barely think straight. I sucked harder, wanking him with my hand whilst he licked me, until I came a second time – this time even harder. My legs were shaking, my arms were almost giving way.

The last five minutes were the wildest.

Lukas sat down on the bench, I straddled his face. I rubbed myself against his tongue whilst working his cock with both hands and my mouth. My breasts bounced freely, my nipples were rock hard. I really rode his face, moving my hips in circles whilst sucking him deep. The pleasure was so intense I could barely breathe.

The 15 minutes were up.

I came a third time, whimpering softly, whilst I had his cock deep in my mouth. My whole body twitched, my pussy pulsed against his tongue, moisture ran down his chin.

We both lay on the mat, breathing heavily, sweaty, glistening, my face flushed, my lips swollen, dripping between my legs. We got dressed and left the cubicle.

I stepped out, my face still slightly flushed, my legs a bit wobbly. The crowd cheered loudly. Many wearing the red glasses whistled and shouted my name.

I smiled shyly and waved. My head was spinning. All I could think was: “That was just a demonstration… just acting with a licking cloth… wasn’t it?”

But my body was telling me something completely different. I was soaking wet, my nipples hard, and I’d just had three intense orgasms – live, in front of hundreds of people, separated only by a thin red strip of fabric.

I didn’t know that for everyone wearing the red glasses, the booth had been see-through.

They’d seen me deep-throating his bare cock, him licking me properly, me coming in various positions – naked, dripping, moaning.

For me, it had been a somewhat daring but ‘authentic’ sex education demonstration.

For the people wearing the glasses, it was the hottest live show they’d ever seen.

I waved happily to the crowd and thought only: ‘For a good cause… and I really enjoyed it.’
