The puni-man temptation of Mio Ishikawa, which destroys rationality. Mio, the wife's younger 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... she's my wife's sister..." No matter how many times I look away, even through the fabric, the obscene shape is visible, and my rationality collapses with the squishy puni-man veins that I can't help but touch! "It's okay to get divorced now...! 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 be stopped by Mio's puni-man temptation that destroys rationality! 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, which any man would want to suck on! That is now a national treasure.
