The old woman notices an unusual stem branching from your main stem about where your groin would be, if you were still completely human. At the base of that stem hangs a large pod. The old woman cradles the pod in her hands, caressing it and feeling it's contents. She feels two hard bean like objects within the pod. As she fondles the pod, you feel shivers of pleasure run through you from your roots to your top most leaves. If you had a mouth, you would moan.
"Oh my!" the old lady says, "So that's what happened to your organs!"
She takes her hands off your changed manhood. You hear her open a cupboard.
You feel her hands work over the pod and stroke the stem. You once again feel the pleasure and it builds to climax. You shoot your load as you have shot since you began puberty.
"My! What strange emmisions! It looks like you've produced a very sticky sap. I'm guessing it's absolutely full of THC." The old woman says, "I think you're a liquid pot producer as well!" she laughs. "If you are, you're a veritable gold mine!"
I must find someone to test this on.
