Step-sibling's ejaculation in my underwear for a day

After a steamy shower, I slipped into my favorite pair of panties and went about my day. Little did I know, my step-sister would catch me in the act, her fingers already exploring her own shaved pussy. The sight of her small tits and smooth belly in my underwear was too much to resist, leading to a wild and kinky encounter. She wasted no time in taking control, making me squirm as she fondled my clit, driving me to the edge. Her expert touch sent waves of pleasure through me, culminating in a powerful climax right into my panties. The sight of her cumming in my underwear left us both breathless and satisfied, making for a truly unforgettable day.
