Fellatio

Oh my god. This seems the only option here. You choose it and a message appears.

'Waiting for the second participant to accept your request.'

You look at the girl and know what she read just now. The expression on her face tells you that she isn't very comfortable with the thought. But she has to accept it, it's the only way.

'Request accepted.' A new message appears.

'Please be gentle, please....' She begs you.

'Don't worry, I won't hurt you.' At least that's the plan for now.

She kneels so the hole in the curtain is right in front of her mouth and waits for your response.

You grab your cock and put it through the hole. The girl looks at it with interest. You notice she is blushing.

'It's nice. Hmm, maybe this won't be that bad after all.'

You know that she is doing this for the first time. At that point you feel bad about it but you forget that feeling very quickly as her virgin, velvet lips approach your dick. You aren't very experienced and haven't masturbated for a few days so you are prepared to finish soon if she plays it right.

'It smells good too. I wonder what is this shower gel they gave us.'

She kisses your erect penis and gently wraps her lips around it.

'I'm sorry, I'm so new to this...' She is really adorable.

'Just do what you can, trust me. You are beautiful baby, I will cum in no time.' You try to give her some confidence.

She starts again. This time deeper. Half of your cock is in her mouth and she slowly moves her head up and down. You try to help her moving your hips gently. You press to the wall so it goes as deep as she can take it. Her innocent mouth is amazing. You start daydreaming about the possibilities. You realize that every day you have a chance to be in this room with a different girl. Hell, you are probably going to have a 'seance' with a girl from your class eventually. You also realize that other students are doing this too at this moment.

'Does it feel good for your cock?' She is so sweet you want to fuck her mouth even more.

'Yes baby. You are great. Keep doing that please!'

She smiles proud of herself. She is less tense now and seems to have accepted her role. She starts blowing you with passion again. She has to be the kind of a person that likes to be good at everything she touches. Even if it's making an anonymous guy cum in her throat.

Your dick is really deep in her mouth. You are very close to orgasm. It's your choice now whether you tell her about it or not.
