In the school bathroom, again

The next day you wake up still sticky from the semen that slowly leaked out of your ass during the night, usually your ass would have been too tight to leak, but the analgesic you used left your butthole very relaxed which you definitely liked.

With just a towel to cover yourself you walk to the bathroom to have a quick shower, your flatmate is on the phone as you walk in front of her room's door and you hear her stammer at the sight of your bare buttocks. You quickly rinse off the scent of sex and after the shower you dress for school: tight black leggings without panties and a loose white t-shirt.

As you walk to school you remember of the couple that offered you a threesome and after yesterday's adventures that sounds very arousing, luckily you saved the girl's number on your phone so you text her "If you liked my voice yesterday, I'll be in the same stall at 9.00 and I may forget to lock the door", then you enter the classroom.

As the 8.00 bell rings she has not replied, but you still spend the whole class fantasizing about the threesome, at 8.55 the class is dismissed and you haven't gotten any messages. You are too aroused to not do anything, so you still go to the bathroom "If I don't masturbate I will drench all my leggings in pussy juices" you think.

You enter the stall, drop your leggings to your knees and start slowly fingering yourself, soon after you hear the stall door opening, you turn around realizing that you really forgot to lock it and you see the girl from yesterday fully naked but for a strap-on.

"Starting without me? That's very impolite of you"

"I thought you didn't get the messag..." you stammer, but she puts her finger on your mouth

"That's enough speaking for today"

She strokes the stap-on "This is usually reserved for my boyfriend's ass, so it's my first time with a pussy I'll try to be gentle", right after she leans in and kisses you, you kiss back passionately. You didn't think that your first kiss would be with a woman, let alone one you don't even know, but you certainly like it.

As you are kissing she slides the strap-on between your legs with the tip barely parting your lips, you spread your legs to give her more space. She doesn't waste this invitation and drives the dildo fully inside you in one single stroke, you break the kiss gasping for air.

She kisses your neck and starts fucking you fast, you vaguely see that the stall's door is open, but don't care, after all you just lost your virginity to a girl you barely know. After two minutes of relentless plowing you are on the verge of an orgasm and she knows it: she slows down just a bit to keep you on edge. You start twerking your ass on the strap-on, but she blocks your hips and goes back to edging you.

"Please" you whisper in her ear "Let me cum", in that moment a man is entering the bathroom but you don't even realize it. She doesn't reply, but she thrusts the cock up to your cervix hard, once, twice and on the third thrust you kiss her to avoid screaming as you orgasm. She doesn't stop fucking you during the orgasm and once it is over she says "I hope you are not done, this is a threesome, remember?", you now realize that the man entering was her boyfriend and that he is now holding your hips.
