HZMEN-001 Thought she was my girlfriend, but it turned out to be a live piston with her sister! I realized this while ejaculating inside her vagina!! SP

I was grounded by my girlfriend and had an insatiable sex drive, always wanting to fuck. So I often just stuck my hard dick into the exposed ass of whoever was in front of me without even looking at their face, pounding away and cumming inside their pussy. Ahh, it felt so good, but then I realized I had stuck it into my girlfriend's sister's cunt, and now I'm absolutely fucked! Or so I thought, but it seemed like I had lit a fire…
