Jeff wanted to see how the long vagina felt the same from the other direction, so he pulled out of her, which nearly gave him another orgasm. "Oh, Jenny, your new vagina is SO magnificent! I'd almost like to keep you this way forever!"
He turned her body around again, and entered her again from her original pussy. Now that her entire vagina was thorougly wet, he was able to push through a little faster, though it was still a tight fit and gave him a lot of stimulation. Once his cock head popped out of her upper vagina, he started thrusting again. "I can't quite put my finger on it, but this does feel slightly different. I wouldn't say that one direction or the other is better, but it does provide a bit of variety. And a different view." He took it slow, though with the huge amount of stimulation provided by the sheer length of Jenny's vagina, he couldn't help but come fairly quickly.
Ordinarily he'd have exhausted his stamina by now, but part of his transformation was to increase that. Also, he knew that Jenny was about to transform again, and that kept him hard.
