IENF-109 The only guy surrounded by girls! The king's game!! Before I knew it, my sister's classmate had stripped me naked…2

When I got home, my sister was having a girls' night out. My sister usually looks down on me, but her friends are very 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 interested in sex, the harem-like king's game entered dangerous territory! Wait a minute! Even with my sister this is too much, right!
