Description
At my friend's house, I encountered a lewd phenomenon where my sister's huge breasts were crushed and her breasts were fully exposed! I was staring at her through the door, thinking that she wouldn't notice, but my crotch was fully erect! However, when I thought that I would be scolded for being found out for peeping, my sister actually invited me! When I looked closely, I was excited to the max because her breasts were bigger than I had imagined! She gently jerked off my rock-hard cock.
