So I really love making Sveta into a huge slut but I wish you could lean more into it. It would be cool if she could be proud of being a slut. With more dialog about how she much loves sucking dick or being fucked. How much she loves hooking up with lots of guys and even brag about how many guys she's fucked. Characters could even ask her how many guys she's fucked/sucked off that day or even in total. I get it makes her a social outcast but maybe she doesn't care?
If Sveta's known as a "cocksucker" "cum dumpster" or whatever. More guys should be coming up to her at school about trying to hook up during breaks. Like if she's known for being easy, guys are gonna shoot their shot. It happens so infrequently currently. Also during breaks, there could also be an area in the school she could hangout that prompts guys to ask, or she could seek guys out herself and ask if guys want to hook up. She could also charge if she wants, if she's a whore.
In class when talking to classmates/random classmates could ask for handjobs under the desk or Sveta could offer to give them a handjob too if she's killing time. She could possibly try to sneak out of class with the classmate to properly hook up.
Being able to ask guys if they want to hook up in the street. When I say hook up I mean with a full list of options like with the hook up system already in place. (handjob, blowjob, vaginal, anal... etc)
Different sex acts could have their own skill attached to them. If she has 90+ in blowjob skill she could be known as a "throat goat" along with the renown tags. maybe blowjob skill and amount of blowjobs given to achieve the tag.
When a hook up encounter happens it would be cool if lets say Sveta didn't have a lot of time but still wanted to be slutty she could offer to suck their dick near by in like 10-30 mins. depending on how good she is at blowjobs.
If both Sveta and Sonia are both sluts and best friends. It would be cool if they had little wagers of how many guys they can fuck or blow in a night of 50p - 500p or even just bragging rights. They could talk about it on the Friday at school for Friday night and for Saturday she could be hanging out outside the disco before it starts and you could ask then.
There should be and option when Sveta's at the dance and is a slut. If she's dancing with a guy, she could whisper in his ear about how much she wants to suck his dick or fuck him and drag him outside or the bathroom. She could even tell him about the bet straight up when he approaches Sveta and say "I'm betting Sonia I could suck more dicks than her tonight. Can you help me?"
It would be cool if Sveta's a whore as well she could offer services for free if she wants. Or similar to the hook up encounter offer to suck their dick if she didn't have time or isn't into something like anal.
