Vaping Makes My Step-Sis Leah Horny

As it turns out, my stepsister and I share more than just a surname. We recently discovered that we both secretly indulge in vaping in our separate rooms, unbeknownst to our parents. Curiosity about other potential forbidden activities crept in, and Leah, my stepsister, dared to tease me by massaging my erection with her feet.
The psychedelia of the vape clouds perhaps contributed to the arousal that followed. Before I knew it, she was skillfully performing oral sex on me as she puffed from her vape pen, a surreal sight. I could hardly fathom the situation, concerned about the imminent risk of being caught by our parents.
Evidently consumed by desire, Leah demonstrated clear signs of wanting me as her arousal became noticeable. With utmost urgency, I penetrated her moist genitalia with my sizable member, vape pen still in hand. Engulfed in the steamy act, we maintained our vape sessions throughout.
Bringing her to climax, I ejaculated over her countenance, while she nonchalantly inhaled another puff from her vape pen.
