I pleasure myself while watching my stepmother's curvy backside and climax inside her - A full narrative

After a long day at work, I found myself alone in the house with my girlfriend's mother. As I lounged on the couch, I couldn't help but be captivated by the sight of her voluptuous curves and natural tits. Her luscious ass was a sight to behold, and I found myself getting aroused. In a moment of weakness, I succumbed to my desires and began pleasuring myself while imagining her. The thought of her thick, curvy body and her ample bosom ignited a fiery sensation within me. I was lost in my fantasies as I reached my climax, imagining her big ass bouncing as I fucked her from behind. The intensity of my release was heightened by the thought of her, my girlfriend's mother, and I was left breathless and satisfied. As I came back to reality, I couldn't shake the feeling of guilt and shame that washed over me. I found myself questioning my sanity, wondering if I had crossed a line. But one thing was clear - I had just experienced the ultimate pleasure with my girlfriend's mother.
