Curious and horny, I found my step-sister-in-law, Marianita, alone in the house. I seized the moment, groping her curves and feeling her up. She was hesitant at first, but the sight of my throbbing cock in her face made her comply. She took me in her mouth, gagging on my length, her small tits pressed against my thighs. I fucked her face, pushing deep into her throat. She took it like a champ, tears streaming down her face. I couldn't hold back, and I blasted my load all over her pretty face. She gasped, shocked but turned on, tasting my cum for the first time.
