I was hoping to have sex with my aunt who has a sexy plump ass, so I went to her house with an aphrodisiac and a hidden camera. I pretended to help her with the housework, but as I was staring at her sexy ass while she was mopping the floor, I got a full erection in my pants. I couldn't hold it in any longer. I mixed the aphrodisiac I had prepared into her drink, and when I gave her the drink, she said, "That's strange... I'm starting to feel feverish..." I pretended to take care of her, and gave her a feather-touch on her hot, flushed body. Every time I touched her, her body trembled and she gradually lost the strength to resist... and I secretly filmed her like that!
