The doctor tells the girls to get undressed and to lay on the tables. They both exchange looks of worry but they comply and the doctor straps them in. The doctor comes back a few minutes late carrying two syringes. He injects one into Ariana and one into Emily. They both feel a wave of please wash over them as they pass out. When Ariana wakes up she feels different. The restraints feel tighter and she doesn't heel her long hair anymore. She still feels hot, mostly near her crotch. She looks down to see that her breasts have disappeared and that she now has 6-pack abs. She wonders what happened and she feels the wave of please again, she moans softly and she notices that her voice is deeper. Then the doctor comes and pulls a lever that makes Ariana sit up with her legs still flat on the table, parallel with the ground. She starts to feel the pleasure again, but this time she sees something. She sees her clit start to grow and her torso starts hurting ad her ovaries drop and she starts to see a flap of flesh on her vagina. Then she sees her clit start to grow outwards and she realizes that she is growing a dick. Her dick continues growing until flaccid it is 9" flaccid and 1' erect with it being 2" wide flaccid and 3" wide when erect. the she feel her balls start growing until each are the size of a baseball. Then she starts getting an erection and the doctor tells her that her new name is now Andrew and she is now a he. Then he injects Andrew with a sedative. A few minutes later, Emily wakes up. She notices nothing until she looks down and see that her normal C-cup breasts are now DD-cup breasts. She stares, shocked. The she notices that her hair which used to be brown, is now a golden blonde color and is about 1' longer. She also notices that her nails have grown longer and are now painted pink. She notices nothing else. And then she looks to her left and sees this 6' 4" man laying on the table with a gigantic dick. She doesn't know why, but she had this irresistible urge to suck his cock. Just then the doctor walks in. Andrew starts to wake up, slowly. The doctor explains that he had increased Emily's estrogen levels 10 fold and increased Ariana's(Andrew's) Testosterone levels 20 fold. The doctor now explains to Emily that Ariana is now Andrew and that they are going to be released soon enough. They both start arguing, but the doctor just walks out. Soon the restraints let them go, but they find that their clothes have disappeared. The sit quietly until Emily looks over at Andrew. She sees his dick. Andrew sees he and he thinks that he would love to fuck her, Emily was thinking the same thing. Their Estrogen and Testosterone levels were increased greatly so it would only make sense. They went at each other. They moved to the bed with silk sheets. Andrew was laying on the bed, his erection making his dick huge. Emily came and had Andrew stick his dick inside her pussy. She starts sliding up and down. And soon enough she orgasms, and eventually, so does Andrew. Then they just lay there. Little does either of them know, the increased testosterone levels made Andrew have super seed.
