Derrick stood there mesmerized, feelings in him running wild while he did not know what to do as say.
Julie was busied watching her brother becoming something other than of what he was born, as she was becoming the essence of a Greek woodland nymph. She too felt with wandering hands, was becoming aroused by the sight of her changing brother.
"Oh, oh Derrick, now me too," she said as then her hands began to stroke along her sleeker breasts, they firm as quite perky. Her fingers danced about feeling her aroused nipples, as they had gained a distinct up-turned angling. Lovely shaped breasts and her slimming waistline bade her to model her form in a full length mirror.
"Whatever is this I like what I see," Julie said, she too removing her clothing, to where she stood wholly naked but quite unashamed. She noted then how her firmed breasts and aroused nipples, the nipples had changed again, as turned black of color, and extended, they beginning to leak then drips of her milk.
"Whatever is this, its not really weird, it makes me feel quite horny. Julie, sis, as I look at what you are becoming I feel wildly aroused. I think I am like a Greek myth satyr, but seeing my sister becoming a nymph makes me what to yell..., I, ah baa, baa...!" Derrick said.
"Derrick," Julie exclaimed, she speaking his name to remind her that the satyr standing there was her brother.
"I love to see you as you are now, your furry legs, those cute goaty horns, and what happened to your dick and balls, as wow, wow, wow!" Julie again exclaiming said as to her changing ideas about her brother being but a brother but then he becoming worthy as a possible lover.
"Me too, as to look at you Sis, my being a satyr feels great but something in me begs me to want of my body becoming more that like a buck goat. I get really aroused and I then feel the need to bleat like a goat getting horny." Derrick said, as Julie stood feeling her arms with more petite like hands.
"When you bleated some minutes ago, I had a wish that you should lose all of what is left from being human, as become more like a large male goat. Even as you stand there looking so sexy, seeing the new me, while my changing completed, your eyes changed their color, your pupils are a golden yellow color. What I see looking at me is but the slightest reminder of a brother having become a satyr, is showing visible signs of your feeling aroused with beastly lust.
As I stand here and stroke my hands feeling all about my changed body, my tits leaking milk due to my own aroused feelings. This is more than a wondrous vacation we are enjoying, as you being a big brown furry satyr now fully aroused, I like the looks of your long, as hotly reddish colored erection. You are making me swoon to want for you to come closer, as so close that your foot long cock should come, let it slip into me, letting us know the feelings of my snug vagina.
Come satyr brother, act as if you were a goat having sex with a equally lust loving woman. Yes lets us do it standing here, you my buck with his cock inside a new nymph, we hugging, let me my hands roam, feel my fingers combing through the thickly grown goat wool covering your goaty butt." Julie remarked, as she lured her brother into a want for incest Greek mythical style.
Julie was of great hopes and Derrick eyeing her, as he began pelvic thrusts, urged their bodies to teeter and fall backwards together onto what was to be her bed, where the want for sexual pleasing began anew!
