Perfect Body Single Virgin Dormitory ~The manager's amazing hip swing~

The single dormitory I moved into was not a normal dormitory... Every night, I hear sweet voices coming from other residents' rooms... When I peek in, I see that the manager, who is kind and beautiful during the day, is straddling a man and shaking her hips as if she has suddenly changed! Every day I'm constantly being teased by a naughty manager who has no interest in anything other than virginity...
