"Big sister?! Aren't you so close...?! Hmm?!" She secretly rubs my dick and makes me moan, but she covers my mouth with a French kiss so my wife doesn't find out and then starts to play with me. My wife's sister, Ichika, is a calculating and naughty woman who came to stay the night (sweat). She wants to do it anytime and anywhere, whether it's in a family restaurant, the garage, or the bed where we have sex, and I'm confused, but it feels so good that I just let her do it. I'm the worst because I climaxed instantly with her erotic tongue.
