Secretly watching my reserved sister shower leads to intense vaginal penetration and ejaculation in the first installment

After a long day at work, I found myself craving some intense pleasure. What better way to unwind than to indulge in some forbidden fruit? You see, I've been harboring a secret desire for my reserved sister, who just so happens to have the most tantalizing curves. I decided to sneak a peek into her room while she was showering, and what I saw was pure heaven - her luscious round ass glistening under the hot water, her perky tits barely covered by the soap suds. I couldn't resist any longer and rushed to the bathroom to join her. The sight of her naked body only fueled my lust, and before I knew it, I was penetrating her tight pussy with wild abandon. The pleasure was overwhelming, and as I reached climax, I filled her with my hot load. This was just the beginning of a new chapter of forbidden pleasure.
