Give them a womb tattoo

With the evil boss on their knees. You feel your womb tattoo glowing and burning. It aches to be shared, it needs a sister. Your nails skillfully draw the form of a womb tattoo similar to yours, one that would make them have the same cravings you feel. The evil lord's body changes in front of you, bones molding, flesh growing and shrinking in all of the right places. A purple aura engulfs their body for a few moments until no trace of the once proud presence can be seen. In front of you, there is only a blushing mess with her eyes in the back of her head from the strong orgasm she just went through...Both of you are too far gone and as your adventuring days are over so are your sister's...A few months after, two women can be seen accosting a man in a nearby alley. "Come on mister~Why don't you let us give you a nice time." One of them pouts. "Yeah, we will drain you so good, you will feel eternally grateful for our service...~"
