A Halloween challenge discovered in Nakano! If your busty girlfriend can resist reacting, you can win a 1 million yen "no-reaction game"! SGKI-042

"Want to play a more fun Halloween game?" A game with a 1 million yen prize was offered to three couples in high spirits after drinking. The game involved challenging various games within a time limit (the boyfriend was blindfolded and had loud headphones). As long as the girlfriend didn't turn around or show surprise, she could be sexually assaulted, masturbated, or played with using a vibrator—all were acceptable. Try squeezing her boyfriend's large breasts that he couldn't keep his hands away from! Play with her with a masturbator and a vibrator until she couldn't hold back and ejaculated! Finally, there was a sex game involving penetration. Winning the grand prize wasn't easy!
