Jon realized that other than the genitals, he, or she, still had his original body. All the secondary sexual characteristics of being a man. While Sarah still had breasts.
Jon briefly wondered "does that mean that my new gonads will not produce estrogen but testosterone instead, since estrogen would not be consistent with me not having breasts? Or would I start growing breasts if I stayed like this, and I would start looking more feminine, while Sarah's would be reabsorbed by her body over time and start to look more masculine? Oh well, I won't be staying like this long enough to find out."
Jon snuck over to the side of the bed to get the box out, which contained the stone. And Sarah sat up in bed.
"What'cha up to, honey?" Sarah asked.
"Oh, uh, just, checking on my pet rock," Jon said.
"Pet rock? You actually have one of those? You silly girl."
"Ha ha, that's me, the silliest girl of them all," Jon said.
"You weren't so silly a few minutes ago," Sarah said seductively, stepping out of bed and sweeping close to Jon.
"Oh, about that, uh," Jon stuttered. Sarah was still a girl, and an attractive one, in every place but one, and Jon was flustered about this.
Sarah kissed Jon. Sarah's breasts pressed into Jon's chest. Jon was in turn thrilled despite herself and sexually turned on. Maybe he... she... could... maybe it wouldn't be so bad if... no, that's an awful thought!
But it was a moot point debating it. Because while Jon was thinking about this, Sarah had embraced Jon in a close hug. And even though they were both standing, it went in. Jon felt a flash of pleasure at this, and felt like she was having a re-invigorated erection, but knew this had to be her new clitoris.
Jon didn't know whether to be more shocked by this happening or by how much her body was responding to it. While thinking about it, Sarah turned Jon around and pushed her over on the bed.
"Time for round four!" Sarah announced.
" Four!? " Jon squeaked, shocked and appalled. Sarah tenderly but vigorously started kissing Jon all over the neck and check. Ah, to hell with it. Jon kissed Sarah back.
