Jen felt an odd suctioning sensation, and she was able to let go of the base as it bonded with the bare skin between her shoulders. Her nuts came to rest just over her breasts, and the weight of them seemed significant. She could feel the pleasant throb as her shaft rose up, her vision beginning to tilt toward the ceiling. Still able to look in other directions by bending over a little, she could angle the stiffening rod so it would point more horizontal and allow her to see elsewhere, but as it slowly got harder, that became more difficult.
Nervous and confused, she wondered what to do next. Her head was nearly fully erect, very warm to the touch, and stiff. Thicker than she expected, there was a compulsion to touch the shaft, and before she knew it she was gently stroking the smooth skin. The attention make her new head harden even more, and she began to feel like she had a tree trunk growing out of her shoulders.
Awkwardly, Jen came to her feet and began to make her way through the house to her room from the bathroom. It took some care of movement not to bump her new anatomy on any fixtures as she went. Keeping her vision even was disorienting and difficult, but finally she got to her bed and sat down. Taking a breather to get her thoughts together was necessary, but she soon realised what had to happen. Her erect cock was sensitive, rigid, and begging for attention. There was no question, she was going to have to masturbate her swollen head.
