SSNI-340 "Delicious" girlfriend's sister than

I was invited by my girlfriend to my house, but I didn't hang out with my girlfriend a lot and "play" with my girlfriend a lot. Since he came here, his lustful older sister Ayami has always paid attention, even repeatedly deliberately performing sexy and arousing actions on him. He's gentle and shy, but he's equally lustful, so when he sees his girlfriend doing that, he can only sneak a few glances from time to time and then quickly turn away in embarrassment. Discovering this, the older sister moved closer, and not long after that, secret love affairs between the two often happened behind her poor sister's back. Surely the younger sister will regret it if she knows this, regret bringing her boyfriend home, regret trusting her spoiled older sister too much..., but it's okay, everything that happens between the two is okay. done in secret so it is very difficult to detect.
