Not so bad.

Jack now found himself in his older Stepdaughter's body, a situation that occurred due to her thinking about him while she was alone in bed.

As he prepared to take his first shower in her body, he felt a wave of nervousness wash over him.

He understood he should feel angry with her and not enjoy this experience.

Yet, her body was incredibly sensitive, making it difficult for him to resist the sensations.

He stood in the shower, the hot water dripping over his sensitive flesh, and he found himself getting turned on. 

He placed the shower head between his legs.

He could not help thinking to himself as he did so that maybe being inside his Stepdaughter's body wasn't going to be all bad after all.
