Unaware of my presence, my stepsister lay on her bed, legs spread, fingers working her pussy. Her big boobs heaved with each breath, nipples hard. I watched, entranced, as she brought herself closer to the edge. Suddenly, she noticed me, trying to hide her embarrassment. I smiled, approaching her, and she relented, letting me take her place. Her pussy was hot, tight, and soaking. I licked her from ass to clit, feeling her squirm under my tongue. I pushed my tongue inside, fucking her with it, before sucking her clit. She came hard, her pussy gushing, her juices dripping down my chin.
