Galaxy Online: Harem Across the Universe

Kenny Stone, an average but intelligent man, was going about his monotonous, day-to-day life when he died due to an unfortunate accident. However, to his surprise, he was soon transported into an alternate dimension! Posessing the first-ever artifically created body, he soon discovered that this universe had many differences from his own.
Countless aliens lived in tandem with humans?
The universe was interconnected by a single online game and system?
Nudity and sex in general were viewed with complete indifference?
Kenny found out that it was up to him to spread the greatness of intercourse on an intergalactic scale, all while becomming the greatest Galaxy Online player to exist!
