Chubby stepsister's panties were a forbidden treasure. I'd sneak into her room, touch myself through her underwear, imagining her on top of me. The thrill made every stroke lead to an explosive climax.
I'm not sure what it is about my stepsister's underwear that's so damn sexy. Maybe it's the way they cling to her curves, accentuating her round, chubby figure. Or perhaps it's the forbidden thrill of indulging in her intimate garments, a secret pleasure that's as thrilling as it is naughty. Either way, I can't resist the allure of her panties, and I find myself reaching for them whenever I'm alone in the house. It's a solo act of desire, a masturbation session that always ends with a satisfying release. My cock throbs with anticipation as I slide my fingers into her panties, feeling the soft fabric against my skin. The sensation is enough to make me hard, and I can't help but stroke myself until I reach that euphoric climax. It's a private moment, a secret pleasure that I savor every time I'm alone with her underwear.
