I pleasure myself in my girlfriend's red underwear and climax on top of it like the lingerie

After a hectic day at work, I found myself craving some steamy action. I stripped down to my undies, specifically my girlfriend's fiery red undergarments. The risqué lingerie, a brassiere and panties, had an irresistible allure. I couldn't resist the urge to pleasure myself. My cock throbbed with anticipation as I began to stroke, my hand expertly working over the length of my shaft. The sensation of the silky fabric against my skin only heightened the ecstasy. My body trembled as I neared climax, the pleasure overwhelming. With a final, powerful stroke, I released a torrent of hot, sticky cum, covering the underwear in a thick, creamy layer. The sight of my cum glistening on the red lingerie was a sight to behold, a testament to my unbridled lust. The post-orgasm bliss was intense, leaving me in a euphoric state. The experience was a tantalizing mix of pleasure, fetish, and raw desire.
