Jeff continued to very lightly stroke her snake dick. She still felt so very confused trying to think with both heads. Jeff was a guy, wasn't she? She still had a penis, after all, and looked mostly like a dude. But she also couldn't ignore the surprisingly human-like vagina the snake who was her penis had, or the increasingly less alien thoughts her snake brain continued to have about finding a good nest in which to lay a clutch or three of eggs. Jeff was the sort of guy who had decades of people accusing him of thinking with his dick, and now here she was with a real trouser snake between her legs and strange reptilian mind all of its own to think with.
Jeff wondered if she could regain some of the balance of her manhood by exploring some more Chronivac options. Her thought process led her to imagining the huge balls of a horse and thinking big balls might be a manly expression. She wondered if she should use the Chronivac with both hands, but still enjoyed far too much the simple pleasure of stroking her hand down the scales of her snake. She would respond in kind by nuzzling her snake head into the hand stroking her, shivering with pleasure down her spine, as she preened with joy.
Jeff could feel her snake pussy moisten again, and the cum glands in her snake mouth swollen with sympathy. In trying to avoid a masturbation session so soon after the last one, she applied the changes on the Chronivac without paying enough attention to double check them.
Jeff did feel so manly as her legs began to hugely lengthen and bulk up as Jeff grew into the muscled, powerful legs of a horse. She could feel balls drop below her snake part and sent her snake head down to slowly investigate. They did look pretty big and powerful, but those her illusions at additional manliness were shattered when she realized those balls hanging down below her snake dick were in fact horse udders. She licked at them with her forked tongue, surprising herself with the pleasure as her udders engorged and the taste of a drop of milk on her snake tongue.
This was turning Jeff on so much more than she expected, and found herself getting so much more wet than she expected. In addition to how wet her snake pussy had gotten, her snake head was almost instinctively drawn to the sound so the waterfall from the cavern of the horse pussy behind her udder, which looked so huge to her snake eyes.
Everything about the warm cave seemed so appealing to the snake brain between Jeff's legs, and she quickly dived into its interior. She licked the walls, gently enjoying the pleasurable spasms that returned. The cavern was so delightfully warm and pleasantly enveloping and she felt it might be a wonderful place to nest. Jeff moved a hand down to masturbate the pussy that wasn't being filled by her snake head, the one towards the base of her snake, while the other hand followed and was soon playing with her sensitively milky udders.
Soon her already engorged cum glands couldn't help but paint her cavern in the sperm they produced. Spent, she felt it a cozy enough place to nap.
With her other head asleep, Jeff wondered if maybe now was a chance to correct things, with maybe fewer confusing thoughts in her own head. She realized the confusion down below of how nicely filled her mare cunt currently was, and how much her hands were covered in the pleasurable products of her udders and pussies.
