Eden the last woman in universe had been traveling around and observing how society had progressed. A lot of men were basically raised gay due to no women being available. They all used robots in order to create more men and it was so bad that now the only genes that men could create had XY-chromosomes where only guys would be produced in the machines. Supposedly there was some sort of system to regulate the human population so something like this wouldn't happen, but apparently it was overwritten by something.
Eden looked down on earth to try to find an area where she could create a group of women to start repopulating the universe. She scanned and found an interesting group with a name "Increasing Masculinity in those that lack" the somewhat curious woman said out loud "Imittl... nope don't think it works as an acronym... however if those who aren't manly are struggling for acceptance... maybe they should look towards the other side." she landed her small spacecraft down on earth near the club (a fairly normal occurrence) and walked inside. The weak or fat "men" inside were discussing things and trying to exercise with weights to minimal success when Eden came in. When they saw the woman they stared at her and were a little confused. They were thinking that she was an odd looking guy with features they hadn't seen before.
One of the guys, a scrawny shrimp with short brown hair named Kevin, asked "Are you alright Mr.? We're here to try to increase masculinity and it looks like you could use help as well. Is that why you came he-"
Eden interrupted him with a flick of her long black hair and then said "I'm not here to make myself more masculine, but to offer you guys another option to be accepted in society... Something which your society has forgotten a long time ago."
Kevin asked "and what would that be?"
Eden looked into Kevin's eyes with her warm brown eyes and took his head into her hands and said "Something called femininity, attributes possessed by individuals who are female. A gender that you men have seem to have forgotten about." Kevin's body started to feel lighter as his slight muscles shrank away and his skin became smoother, Eden continued "While not strong in physical brawn females have other things to them such as maturing faster." Kevin's body started to reshape itself as his face shifted to something more feminine and his waist shrank in. Eden finished and said "Not just that but females allow a warmer relationship with children, instead of just pumping them out of a machine women nurture the children in their bodies till they are ready to come out. So how about you help me put women back into this reality Miss?" Kevin's organs started shifting and changing as his dick sucked itself in and changed into a vagina and his, now her, breasts started growing out of her chest till they became D-cup breasts.
Kevin the new 18 year old woman just stared at Eden as everyone else stared at her. Eden said "Just concentrate and you can make more women, now spread out femininity on earth i'll be spreading it throughout the universe."
Kevin just realizing that her body had changed significantly touched his chest seeing how sensitive and bouncy her boobs were. She then noticed something and moved her hand to her crotch realizing that there was nothing there. Kevin remained silent for awhile when everyone else just stared and then...
