Secretly watching my sister pleasure herself while vaping at home

As a loyal boyfriend, I'm always attentive to my girlfriend's needs. One day, when she wasn't home, I decided to tidy up her room. That's when I discovered a hidden camera. Intrigued, I checked the footage and was met with a shocking sight - it wasn't my girlfriend, but her sister, who was vaping and pleasuring herself on camera. Her tantalizing tits were on full display as she skillfully worked her fingers on her moist folds. The orgasm was so intense that it left her gasping for breath. I couldn't help but get a thrill from watching her intimate moments. But when my girlfriend found out, she was understandably upset. I had invaded her privacy, but the allure of that forbidden fruit was too strong to resist.
