Jeff for strange reasons that seemed to be less and less clear as time passed still had some vague conception in the back of one of her three heads that perhaps she should be more masculine. Between her heads Jeff decided that not much could be more masculine than a second penis. This seemed a very rational decision especially to what she was continuing to think of as her main head, the snake penis with horny snake vagina. Male snakes have hemipenises, it's quite masculine that head rationalized, and all of her heads agreed.
Jeff had convinced herself and used the Chronivac to do just that, this time making sure to set the gender of her second snake dick to better balance the three heads she already had. Her main head, watched gleefully, as the horse girl crotch began to bulge with her new twin. The new head's confusion was quickly replaced with horny welcomeness as she began to see through each other's eyes directly at herself in all her increasing glory. She glanced to the growing erect hemipenises of her "little brother" and needed no further invitation because they were both thinking the same thing. She quickly engulfed the small snake penises with her wet and hungry snake vagina, the pair of snake penises twisting and spiraling together in immediate love making. They twisted themselves into position to dive into Jeff's waiting horse pussy. Jeff was pleased to discover the added girth of the helixed penis snakes felt almost perfect in there. Jeff had four human hands but almost had difficulty figuring out which ones to use on which remaining pussies and breasts.
A small whisper in the back of Jeff's largest but perhaps most naive head was certain it had been played again. But she was in so much pleasure to worry about that. Her main snake penis felt for sure that she'd be laying eggs now, and as Jeff ruffled her feathers in shuddering orgasm waves, she was starting to wonder if her horse womb might also be preparing to lay eggs as well.
