Slightly hardcore for SLRO but nothing too crazy (certainly not as crazy as I’d really want with pissing involved!).
Scenario is this:
It’s the night before your wedding and your ex-girlfriend shows up at the door saying she wants to talk. We then cut to inside where she tells you that she wants you back, that she’s “way hotter than that bitch” and she doesn’t want you to marry her. She opens her coat and is wearing nothing underneath except a sexy pair of heels (that ideally are kept on throughout)
She says that she’s sorry for cheating on you and that it’s the worst mistake she’s ever made but if you don’t get married she’ll make it up to you “I’ll let you punish me, do everything you’ve ever wanted to do to me and treat me like a whore”
You grab her by the throat and slap her hard across the face twice. She asks you to “slap me harder, I’m your fucking whore now”. You slap her harder and shove her down to her knees. She starts sucking your dick and struggles to deepthroat it. After a few seconds you grab her head and push your dick all the way down her throat balls deep and throat fuck her.
This continues until she tells you to get on the bed and continues the rough blow job before climbing on top of you for cg, leaning in close talking dirty to you as you slap her tits and face. Then reverse cg with plenty of ass slapping.
You then put her in doggy and she tells you to put your cock back in her. Instead you start playing with her asshole “What are you doing?”and then place your dick on the entrance to her asshole. She spits on her hand and rubs spit on her asshole “Well I guess I said you could do anything, stick it in my ass then you pervert and fuck me like a bitch”. Lots of anal in doggy and lots of dirty talk “fuck my ass, use that ass to make your cock feel good, fuck me like a whore” etc. Then some ass to mouth and flip her over into missionary. More anal in missionary, fucking her hard, making her scream, slapping her tits, slapping her face. Finally you pull out and she slides down the bed for you to jerk your cum all over her face. If it’s someone with big tits you could even titty fuck her until you’re ready to bust on her face.
Obviously this would need a girl who can deepthroat, who loves anal and enjoys rough sex. Gia Derza is a name that springs to mind or Brooklyn Gray, Adriana Chechik, Jesse Pony (not sure if she can deepthroat though).
