Ryuko rides the reader in a park.
You've been suspecting Ryuko's up to something since she met up with you wearing a light sundress. Something about it just stood out, the way it looked so flimsy and easily moved. And she doesn't take long to confirm your suspicions either, as she lifted her dress up to expose the utter nothing she's wearing beneath it just long enough to make your cock stiffen in your pants, just long enough to make you feel the cravings and needs of something absolutely mad, something raw and desperate and unafraid. She exposes herself to you, shoves you down onto the park bench behind you with a very light shove of a single finger, and then climbs up onto you.
Ryuko's mind is set on fucking you in the park, and Ryuko Matoi with her mind focused on anything is a very dangerous state to find yourself involved in. She doesn't give a single fuck about how there's people walking around as she sets herself down onto your cock and gets to greedily riding you hard, your cock easily taken out and shoved down onto, with her tight, slick pussy doing so much to warm you over and leave you almost sort of wanting this, as she holds on and takes charge in that way only Ryuko can. She's got that look in her eye, got that gleam and that firmness and that desire to have something, and that something happens to be your cock in public in the middle of broad daylight. What are you going to do to stop her?
The answer is nothing, as she hammers herself up and down onto your cock and you just take it. She rides you shamelessly, the firm heat and aggression behind these motions showing off everything you could want to know. It's a direct and brilliantly senseless show of heat that awaits you, as your cock once more feels like the plaything of Ryuko Matoi, and you can do little but grab at her hips, trying to tug the sundress down so it's not showing off her gorgeous ass for everyone else to see. If nothing else you can keep that perfect backside 'yours' even in the midst of this insanity.
Ryuko presses her forehead to yours. "Cum in me," she says, sucking in a sharp breath and biting her lip. It makes you fucking melt. You give up to her demands, cumming inside of her tight, greedy pussy happily, opening yourself to this mess and accepting the idea that nothing will spare you now from her madness. Every throbbing shot of cum into her pussy as she hits her peak moaning and spasming atop you is incredible and unrepentant, with you happily just accepting the mess for everything it's worth. She screams your name out for everyone, letting them all know who you are as you cum inside of her, and it should bother you more than it does, but fuck it, you're just so excited by this that as Ryuko slides off your dick and kneels down in front of you to begin cleaning you off with her mouth, you're going along with it.
And hopefully not getting fucking arrested in the process.
