Steffi is waiting for you

You are surprised to see Steffi right outside the classroom. The icy stare she gives you is enough to send a shiver down your spine.

"Hey...", you awkwardly say as you walk up to her. She stays silent and continues to stare you down. "Look, I don't know what you were thinking but I don't think the classroom is an appropr..."

"Do you want to ever have sex in your life, John?", she abruptly cuts you off.

"W-what? U-uh, yeah...", you stutter.

"Well, you should learn how to grab the chance and not let go when the opportunity arises, or else you will die a virgin", she replies sharply.

"Follow me then." The tone she uses makes it sound more like a command than a suggestion, so you quickly obey her. She leads you towards the female bathroom.

"Wait here." Steffi slips in and comes back out after a few seconds. "It's empty, come in."

"Wow. Maybe she IS still in the mood, and I'm gonna have my first handjob, maybe more", you start to dream again with a smile on your face.

She heads to the furthest stall and closes the door behind you. It is a little bit cramped inside for two people so she sits down on the toilet and looks at you expectantly.

"Need an invitation? Take off your pants", she orders. You don't need to be told twice, the outline of your boner fully visible through the thin fabrics of your underwear. Like before, Steffi starts to slowly jerk you off through the fabrics, but this time, you can actually lean your head back and enjoy without the fear of being seen.

Even though Steffi's hand isn't in direct contact with your dick, you can still feel every movement as well as the heat of her hand. The new sensation quickly brings you close to orgasm, as your breathing becomes ragged and your cock begins to pulse.

"Your hand feels so good, I'm gonna cum", you quickly warn Steffi, and at that exact moment, she grabs the base of your penis and squeezes hard, blueballing you in the process.

"You. Never. Reject. Me. Again", she says, releasing her grip on your dick and getting up to leave.

"W-wait, you can't leave me like that!", you plead desperately, still frustrated that your orgasm was denied.

"Why not? What do I get in return if I finish you off?"

"Anything you want", you say without thinking, and you see a devilish smile form on Steffi's face. "Only once...", you add, almost immediately regretting the deal that you just made yourself.

"Okay then. Take off your boxers."

You don't waste any more time. "I'll bother about that deal later", you think as you lower your underwear to your ankles. The girl quickly takes your still-hard shaft in her hand once again. The feeling of her hand over your boxers earlier was already incredible, but it cannot compare to how it feels to have it directly on your cock. You always thought a handjob would feel just like jerking off, but the warmness of Steffi's hand working on your shaft is incredible, with every motion feeling surprising and unexpected.

Just as she starts picking up the speed once again, you hear the door of the bathroom open. "For fuck sake!", you scream internally, starting to get annoyed by all those disturbances. However, Steffi doesn't seem to care, as she starts to massage the head of your cock, smearing your pre-cum all over.

You close your eyes and focus hard so as to not moan, overcome by the sensations her hand is giving you. You quickly feel your orgasm approaching again. Steffi seems to have noticed as well, and she yanks your underwear and trousers back up, just in time to prevent herself getting sprayed by your cum.

You feel your hips buck slightly as you shoot ropes after ropes of semen into your pants for a solid 30 seconds, until finally your orgasm subsides. Your knees start to buckle, and you have to lean hard on the wall so as not to fall.

"Is everything okay in here?", you hear a female voice from outside ask. Still panting heavily, you look at Steffi with horror in your eyes.

"It's fine, I just hit my elbow against the wall", she replies calmly as she takes a piece of toilet paper to wipe her hand.

You wait silently until you hear the other girl leave, and quickly sneak out of the ladies bathroom.

"Don't wait for me, I still need to wash my hand", Steffi says dismissively just before you leave. "And don't forget our deal."

"Wow, that was intense! That's the best orgasm I ever had", you think as you find yourself alone in the hallway. "I do have to go back to my room to change clothes though, I can't walk around with a giant stain on the front of my pants..."
