HUNTB-561 - Warning! Warning! Right in front of me is my step-sister with a plump body, struggling to get out of her swimsuit! If I try to help her take it off, her breasts and buttocks keep peeking out! Also, an erection and loss of reason.

Right in front of me is my step-sister with a plump body, struggling to get out of her swimsuit! She's trying various things, but it doesn't look like she can take it off on her own. So, when I try to help her take it off, her breasts and buttocks keep peeking out! I think I shouldn't look, but I can't help but look! As a result, I became fully erect... At that point, I lost all reason and couldn't resist, and before I knew it, I had inserted myself into my step-sister and had intercourse. If a man sees such a plump and erotic body up close, anyone would do it!
