FNS-122 I can't resist when my wife's sister seduces me by showing me her plump pussy line

My wife's sister is showing me her panties... no, not just her panties, but her pussy slit... a tight crevasse between her plump pussy meat... there's no way I could resist seeing something like that and I just jumped into her slender, fair-skinned body...! I'm sorry... but I can't stop having affair sex with my wife's sister at home! We have excellent sexual chemistry, and when I run my fingers along her pussy slit, it gets wet easily, and when I insert my fingers into her pussy, she has a sensitive constitution that makes her cum instantly! I never thought the perfect cheating partner would be so close to me...! The pussy slit is the trap of infidelity...!
