She is totally trying to damage control but Till is a spoiled baby and doesn't like to share. Now Ivan has to made up by letting Till do what ever she wants with her, nothing new but this time Till wants whatever thst other guy has been getting from Ivan and more, she wants the premium service...So what if she invites herself into their table and fingers Ivan right there, right now? She too wants Ivan to sit in her lap and call her sweet names...

Lots of in school fucking (deserted classrooms, bathroom, gym rooms and one memorable outdoors eating out meal). She also fuck her a lot in after school hours she fucks her in Till room but she also fucks her in Ivan room (and makes sure she always remember it) gets all the dirty pictures (some taken before meeting anf after meeting or the period where they see each other...Ivan makes extra sure to show her how much she missed her with those) along the already regular good morning and good night messages but she also takes her out (to dinner to the movies to that astronomy museum she has always liked..."bet that guy only takes you to boring dinners and fancy 5 stars hotels [shoves her knee deeper so that Ivan can keep humping her clit better against it] where did you find such a lame guy, couldn't your dad find a better guy for you to fuck...Bet he doesn't know where is this" [twist her clit and watches her wet herself]) and is totally a better girlfriend but they don't call each other that haha (also Ivan charms are enough to keep the guy abide so she doesn't fuck him...She is saving that for Till ♥️ such a romantic) bonus points when Ivan calls her husband (femtill getting called husband!!!!) and Till calls her wife...She is higher in the hierarchy now than that guy now

As for the other yuri...I could see her doing that the whole point is that Ivan entertains Till to the point of getting crazy horny and attack so maybe that could come later on, for a while Till doesn't engage just watches get off on her fingers, dildos, her own pillow, satisfyers, nipple clams, anal vibrators...You call it...Again i'm not an expert but i could see her been very engaging and into anything that gets Till looking crazed and mad about it (To me, Ivan is more of a frotting kind of gal because she gets to hold and been hold by Till and she likes to feel how Till gets off with her body. Once Till presents her with a strap or a double ended dildo her worldview expands)
