I finally worked up the courage to talk to my next-door neighbor, a big-assed older sister who always wears revealing clothes. She invited me to anal sex, and I had such a blissful experience that my mind went blank with happiness. After we both took some aphrodisiacs, she tempted me by showing off her anus! My dick, which was initially startled by the sudden anal play, reacted honestly and got hard. When I inserted it into her tight, twitching anus, a wave of pleasure shot out from her pussy, and her anal rose bloomed wide open. How beautiful! I couldn't think of anything but anal sex with my older sister, and I became obsessed with it, visiting her every day and drowning in the pleasure of anal sex.
