My stepsister's seductive booty-rubbing leads to a climactic finish in her panties

After a steamy shower, I caught my stepsister's tantalizing booty-rubbing session. Her luscious Latina curves were irresistible, her fat ass glistening under the dim bathroom light. I was aching for her, and she knew it. She teased me, her fingers dancing over her skin, driving me wild with anticipation. As a huge fan of fat asses, I was in heaven. She took off her shirt, revealing her ample breasts, and started to stroke her throbbing cock. The sight of her rubbing her pussy while playing with her big tits was enough to make me lose control. I couldn't hold back, cumming hard on her fat, Mexican ass. It was a breathtaking sight, her babe ass covered in my cum, fulfilling my biggest fetish.
