I've been curious about my junior colleague Mamichan, who has a boyfriend and is a J○... Since she's graduating, I invited her to a popular theme park as an excuse for a graduation trip. To my surprise, she agreed! However, on the day of the trip, the theme park was unexpectedly closed, so we checked into a hotel early. With nothing to do and bored, Mamichan seduced me, and we had sex repeatedly throughout the night until morning...
