There was a tingling feeling inside your balls that itched and annoying the everliving shit out of you as you tried to scratch them. However suddenly your dick and balls retracted immediately leaving behind a slit and you couldn't help but moan loudly.
Suddenly the vinces began penetrating your new slit and all of your focus was on that as your instincts told you to get on all fours.

Males dragons will deposit seeds from their rectum, while females will do so through their womb. These vines will also cause females heat when depositing seeds, and the most likely result will be a female and male couple."
"Are you serious!!! What the fuck!" You roared again, and moments later something was happening and...
