i wake up in the middle of the night feeling a presence in my lower body, and my little sister is straddling me with a meaningful smile, saying, "Big brother, you're awake?" wait a minute!!... i was still a virgin... when i realized it, i was attacked by my little sister and lost my virginity... but my little sister was more erotic than i imagined, and it felt really good. so, even though i lost my virginity in a somewhat forceful night fuck, i have no regrets! i'm just a little worried about my little sister's perversion.
