Sister-in-law pleasures herself while I watch and masturbate

I was at my sister-in-law's place, and as I was browsing through her porn collection, I stumbled upon a steamy video that caught my attention. It featured a stunning brunette with small, perky tits indulging in some intense self-pleasure. I found myself drawn to her moans and the sight of her wet vagina, and I decided to join her in her intimate moment. I began to touch myself, mirroring her movements, as I watched her reach ecstasy. The sight of her orgasm was enough to push me over the edge, and I climaxed shortly after. It was a wild experience, watching my sister-in-law pleasure herself while I did the same, sharing an intimate connection through our shared pleasure. It was a depraved act, but one that left us both satisfied.
