【Rabbit SisterS/Oozora Fukai】Natural chubby big tits sister tricks you into dieting your dick!

Synopsis
“Oh, my God! Hey, I’m in trouble~! Oh, you know…actually…I gained weight…about 3kg…

Yukina" is the older sister who is a natural screw-up and a little bit weak in the head.

She asks me to help her lose weight, so I suggest a sex diet, taking advantage of her weak mind.

This is the first time I’ve ever seen a girl on a diet.
In the beginning, Yukina showed a naive reaction, but then she started to show some reserve like an elder.

I’m going to ejaculate right now when I’m sandwiched between her tits.
I’ll give you a good titty sucking, okay?]
