Sixty nine.

You answer with a grin, “Sixty nine?”

She smiles, “If you insist. The longer I suck you the more masculine you will become, the more you suck me the more feminine, if we suck each other I don’t know what will happen exactly. But if you drink enough of my seed your manhood will be replaced with a pussy even if your body doesn’t match.” While she is talking you pull her on top of you till you can slurp down her magnificent tool. “Very nice.” Her voice lower as your attention causes her to exhale more than intended. Her mouth latches onto your shrinking cock and slurps you in.

Your body ripples with pleasure and seems to want to give in, to become more feminine, but whenever you lap at her balls or lick her shaft or just bob on the head for a bit you can feel yourself growing. Lust demands you let her fuck your pussy. You suddenly yearn to carry a child for her. Images flash of raising a daughter in your head. “I need you in my pussy.” You yell pushing her off of you. She laughs with delight as you wrap your hands around her shaft and furiously jack her off, your mouth locked on the tip eager to drink your fill.

“Drink.” She says and rests her hand on your head as the cum burbles forth. Whatever you have done, or said, or perhaps just your thoughts, have caused her to flow more like a gentle fountain than a beast of pure sex. You drink the flow gulping it down. It warms you. It seems to flow into a void you didn’t know was inside of you. “Good girl.” She pushes you down and mounts you. Her cock pierces your tender new pussy. “You will make a fine vessel for my offspring. She slides it in deeper causing you to moan with delight, your toes curling.

Sadly it isn’t to pass. Her time ends. The spell is over. She vanishes and you are lying on the floor. Blinking, you sit up. A mirror catches your attention.
