It didn't take long before Jon began to feel the effects of the pill. One of the most noticeable early effects was his breasts getting larger. He'd been a small B cup thanks to taking estrogen pills for several years but as he watched they grew to be at least a C cup. Their growth had felt really pleasant and the feeling was actually turning him on a little. They were nowhere near as large as Karyn's wish enhanced breasts which he was grateful for.
Suddenly his face felt weird and then the feeling became pain like his head was trapped in a vice. He looked in the mirror over his vanity and watched as his facial features were reshaped. His nose became smaller, his chin narrower, and his jawline rounder. He still looked a lot like himself, but also a lot more feminine than he had a moment before.
Lara starred watching her girlfriends body transforming piece by piece into a real woman's. Even though she's known the effects of the pill, it was still amazing to watch the changes actually happening. One thing Lara hadn't expected though was how much watching Jen change was turning her on. She was pretty sure she had never been more turned on in her life.
As Lara was coming to recognize a new fetish, Jon was still transforming. His hips had widened considerably to what he recognized as childbearing hips. The pain caused by his pelvis changing shape had been much worse than when his face had rearranged itself. It seemed that changing soft tissue like his breasts didn't hurt, and actually kind of felt good if he thought about it, but changes to bone and cartilage was quite painful.
Jon and Lara watched as fat began to distribute itself differently across his body. His stomach was thinner, though it had never really been fat, and his ass was noticeably larger. His muscle tone had also changes a bit, but not very that much since Jon had never been all that muscular. The pleasurable feeling of these changes was further arousing Jon. His small penis was quite stiff at this point.
The changes seemed to stop for a minute and both Jon and Lara starred confused at his erect penis which still stuck out above his empty scrotum. "Is it done?" Lara asked her voice slightly husky due to her arousal.
"I don't know." Jon said. Then he felt something moving inside of him. He could tell that it was is reproductive organs that were making the final change. "Wait. No, I don't think it's done. I can feel my insides changing."
They both starred at Jon's groin watching for any external signs. Lara was the first to notice that his scrotum was shrinking. She'd thought watching the rest of his body change was arousing, but it was nothing compared to this. She couldn't help herself any longer and reached down and began to slowly masturbate herself.
Jon didn't notice what Lara was doing; he was far to focused on the last changes that were happening to his body. His scrotum was gone at this point so he reached down and felt where it had been. Below his penis he felt two moist, fleshy folds of skin. He ran his finger between them and at first it seemed that he didn't have a vagina but then he literally felt it when his vagina grew deep into his body. He slipped a finger into his new sex, feeling the pleasure of being penetrated for the first time. That combined with the pleasurable feelings of the change pushed Jon over the edge. He simultaneously experienced his last male orgasm, the thin clear cum shooting from his quickly shrinking penis coating his wrist, and his first female orgasm as his vagina contracted around his finger squeezing for all it was worth.
Watching this final change and seeing Jon's orasgm also pushed Lara over the edge and she moaned through her own orgasm.
Without saying a word, both teens lay down on Jon's beds reveling in the afterglow of their orgasms.
"Was it as good for you as it was for me?" Lara asked Jon while still panting slightly.
"You have no idea." Jon said trying to get his breathing under control. They were both a little surprised at the sound of Jon's new voice. They had known that the pill would change it, but it was still a shock.
