I suppose they both like the excitement of running on the edge. I mean, taking a shower after PE it would be not possible to hide the rope or the marks. She wouldn't agree to it if she was too afraid of being discovered. But considering Yui ran into her while she was taking her "dog" out, yeah. Maybe they should take up base jumping, they'd probably love the rush.
Yui is a degenerate and her dad is even more of degenerate. Anyways, the yuri is all I'm here for, and I just wish they remove the dad from this story so that we can focus on the good shit.
Maybe next chapter idk, but at some point i feel like Tsukasa might will input a limit Yui cant accept. Like "i dont want u to tie ur dad anymore".
Also, regardless not wanting to be a dog... for someone that seemed to be very used to sexual desires Tsukasa is a lot more behaved than ive thought.
