While walking down the street, I saw an older sister squatting to adjust her high heels. Her mini skirt had ridden up, exposing her panties, and her massive, bursting breasts were nearly spilling out from her top. Turned on by the erotic sight, I headed to my friend's house—only to discover that the woman was actually my friend's older sister. Desperate to get closer to the sexy older sister, I forcefully convinced them to let me stay the night, then secretly spied on her while she was bathing.
