Size Doesn't Matter

You lie on your bed. It was just big enough for her to lie down next to you. You couldn't help looking down at her still hard dick as it floped over your leg, it's tip sizing up to your cock as it slowly returned to it's normal size now that you had cum.

"I told you, size doesn't matter," Zephyr said. "Look at that tiny dick, bigger than it was in the shower but still tiny compared to mine. I'm just a herm; you should see a real stallion dick. But dispite it's size you still got me to cum while penetrating me. I got you to cum despite being equipped for something much larger." She explained.

"I know, it was really good." You replied, looking up at her face now. "Are you going to tell me how you have both a cock and a pussy?" you asked. "You said you would explain more in private, but we kind of just got home and had sex."

"I do owe you an explanation." She replied. "I am a natural-born hermaphrodite, second generation. My parents are both first-generation hermaphrodites, born when two people conceived while taking hermaphrodite potions. The potions temporarily cause you to grow the opposite sexual characteristics to the one you already have. They are functional and become permanent if you get pregnant as a guy who took it or take a permanency potion if you're either sex. While you are transformed, you have recessive herm genes. This can be passed on to any offspring who are conceived this way. My all 4 of my grandparents took the potion and conceived while doing so, resulting in my mother and father. They then met and bonded over being herms. They then had me. My mother is the one who birthed me, and my father is the one who sired me despite them both identifying as female at the time. However, this changed when my father got into the traditional centaur stuff. She became He and decided he wanted to form a herd. By centaur law, only one male centaur can be in a herd, and male is defined by having a penis ranther then any gender identity. A herd leader can be female only if there are no males. My mother and I could therefore not fit into his herd. He abandoned us when my mother chose not to take a potion and to force one on me as a child. The potion would have made us fully female. He, however, decided to keep his vulva despite his masculine identity and herd leader status. He had the right to do so, but it was very hypocritical of him to try to force the change on us." Zephyr finished her explanation.

"I am sorry to hear about your dad and what he did." You replied, taking it all in. "So if we were to have children sometime in the future, would they be hermaphrodites too?" You asked.

"While I am flattered that you are already thinking about children, no, the gene is recessive. They would only be hermaphrodites if you were to take a hermaphrodite potion when we were conceiving." She explained. "If that were the case, we might both end up having babies." she joked.

You got dressed, the long explanation being enough time for both your cocks to become flaccid and hers to return to her sheath. You then had to struggle even harder to get her back down your stairs.
