[Unexpectedly, ALL naked] I decided to let my wife's sister stay for 3 nights and 4 days, but... this sister is a naturist! She walks around naked, shaking her G-cup breasts! She has a cute face, and you can see the contents of her pussy! She even teases me with a handjob that stops just before climax (crying). I thought I could endure the 4 days, but... I can't stand this! On the last day, I fucked her raw without telling my wife! She's always naked... so she can fuck me anytime, anywhere and I cum inside her 10 times! I wonder if my sister will come to stay again...?
