I pleasure myself in my sibling's underwear

In a moment of lustful desire, I found myself unable to resist the allure of my sibling's underwear. The scent of their intimate area was intoxicating, and I couldn't help but succumb to the urge to pleasure myself with it. As I undressed, I teased myself, slowly building up the anticipation until I could no longer resist. With a sigh of pleasure, I took hold of my throbbing cock and began to stroke it, the fabric of the underwear rubbing against my sensitive skin, driving me wild with pleasure. The sensation was overwhelming, and I found myself lost in the moment, my hand moving faster and faster as I brought myself closer and closer to climax. The tension built up inside me, until finally, I could hold back no longer. With a moan of ecstasy, I came, my hot cum covering the underwear. The sight of my own release on my sibling's underwear was a sight to behold, a testament to the intense pleasure I had just experienced.
