Mio Ishikawa's puni-man temptation that destroys my reason. Mio, my wife's sister, who will stay at my house for only two days. While relaxing defenselessly in her underwear, my eyes inevitably fall on her clearly visible puni-man... "No way... she's my wife's sister..." No matter how many times I look away, the obscene shape is visible even through the fabric, and my reason collapses with the squishy puni-man lines that I can't help but touch! "I don't even mind getting divorced...! I'm going to fuck...! I'm going to fuck!" I fuck like crazy day and night, morning and night! Even in the bath, even if my wife is nearby or sleeping...! The lustful piston thrusts can't stop with Mio's puni-man temptation that destroys my reason! A thorough collection of panty shot angles that make you cum just by looking at them! A situation where you can fully enjoy Mio-chan's beautiful puni-man that any man would want to suck on! It's practically a national treasure.
