I absolutely detest NTR, but this is basically a 3 way relationship (put aside all the other women MC is fucking). I don't think trans Shauna helping you DP Jaime is NTR in the least bit. I don't think if you walked in on trans Shauna fucking Jaime it would be NTR either, as there is no sense of being hurt or betrayal as you are already having group sex with them and they are both cultishly in love with you.**MINOR SPOILERS IN COMMENT BUT I DON"T WANT TO PUT IT UNDER SPOILER TAG**
I'm probably one of the few on here that likes the girl on girl content, especially between Shauna and Jamie as I assume most would shout NTR. I'm probably in an even less popular group wanting T-Shauna to actually fuck Jamie. Even if MC wasn't present (which the girls said they wouldn't do) in a more of a throuple relationship. The two girls are so in love with the MC, and each other as they said in game that it wouldn't bother me in the least if they wanted to be with each other, or to tease MC as he enters a room waiting for him.
