When my sister\'s friend crashed at our place, I stumbled upon her alone and caught her pleasuring herself. Intrigued, I engaged in a steamy encounter, exploring her desires. This amateur beauty, with her natural assets, craved milk, which I happily provided, indulging her fetish. It was an unforgettable experience.
