My girlfriend's little sister, Hotaru, loves me too much. My little sister loves to play pranks, and she always makes my heart race by showing off her nipples without a bra, wanting to see my reaction. "You're always looking at my boobs, aren't you? I'll keep it a secret from you, big sister." Hotaru shows me her clothed boobs, and my libido keeps rising. "Your dick is getting hard, big bro... you can do whatever you want with me." Even though I have a girlfriend, I can't resist having secret cheating sex with her!!!
