IENF-085 The only guy surrounded by girls! The king's game!! Before I knew it, my sister's classmate had stripped me naked…

When I got home, my sister was having a girls' night out. My sister usually makes fun of me, but her friends are really interested in me. We started playing the king's game on a whim, and the orders gradually became lewd; the girls' commands also heated up. Overwhelmed by the erotic power of girls who are into sex, the harem-like king's game plunged into dangerous territory! Wait a minute! Isn't this bad enough with my sister!
