I stumbled upon my step-sister pleasuring herself. She was taken aback but eager. I plunged in, her curves met my rhythm. She craved intensity, leading to a climactic finish in her mouth.

I stumbled upon my step-sister in the guest room, caught in the act of self-pleasure. As a curious guy, I decided to join the action. She was lying on her back, fondling herself, when I approached. I asked her if she'd ever had a big cock inside her, and she eagerly welcomed the challenge. I watched as she pleasured herself, her big natural tits bouncing with each movement. After teasing her, I finally revealed my throbbing member, which she eagerly took into her mouth. I began to fuck her mouth, before moving to her tight ass. She moaned in pleasure as I took her from behind, her big ass bouncing with each thrust. I continued to pound her until I reached my climax, filling her mouth with my cum. It was an intense session, leaving us both satisfied.
