Cum-locked: The Permanent Transformation

Taking advantage of your brother and sister-in-law's stunned disbelief, you discreetly ready yourself, your strokes sure and focused, hidden from their view.

With a swift and calculated movement, you aim your cock at your dad's body—currently inhabiting your mom's form—and unleash a powerful stream of cum. It arcs through the air and lands squarely on his chest, coating his massive tits in your hot, sticky load.

Your dad-as-mom lets out a gasp, his eyes widening in realization and horror. "What have you done?" he manages to **** out, his voice laced with a mix of shock and betrayal as he sees his borrowed tits swell up to watermelon size.

Your dad-as-mom's expression turns from shock to fury in an instant. His—no, her—voice trembles with rage as she screams at you, "You fucking idiot! I am permanently trapped in this body now! Your cum has sealed my fate!"

You blink, taken aback by the sudden outburst of anger. "Why are you so mad? Isn't this what you wanted? To be able to experience life as a woman?"

He—now definitively she—storms towards you, her massive tits bouncing with each enraged step. "You don't understand! I can't shift back! Your cum has locked me into this form permanently!"

Your brother chimes in, equally confused and alarmed. "What the fuck is going on? Why are you so pissed, Dad?"

She whirls on your brother, her face a mask of fury. "Because, you dumb shit, I was only temporarily in this body for an experiment! Now I'm stuck here forever because of your fucking brother's stupidity!"

You hold up your hands in a placating gesture, trying to calm the situation. "Whoa, whoa, whoa. I didn't know that. I thought you were just fucking with us."

She pokes you hard in the chest, her finger sharp and accusing. "Well, you fucked up, big time! Now I'm a woman forever, and there's nothing I can do about it!"
