I got a depressed erection when my sister (two) was embraced by local DQNs in order to protect me.

Sasagawa Riho and Himetsuki Rui's first co-starring role! ! I was living a happy life surrounded by two proud older sisters. One day, my older sisters get caught up in the eye by a famous local DQN senior... The next day, the girls go to the house and in order to save me from DQN, who uses unreasonable violence, they do whatever they want and devour me to every inch of their body... It must be frustrating and unpleasant, but gradually strange emotions start to rise from deep inside my heart...
