Overly muscular

Following Suzi's lead you continue to pump your cock, forcing more cum out and onto her now toned body. "How big do you want to be?" you ask marveling at the rate Suzi's muscles are expanding.

"You'll know when I'm happy," answers Suzi as she looks down at her strengthening body, her hands still massaging the cum all over. As your arm starts to get tired you increase your volume and allow your cock to spurt all by itself. Soon the bath starts to fill up with your cum leaving Suzi to just lay there and soak it all up, occasionally rubbing her cum covered hands over the parts that are above the "water line".

"Mmm I feel so strong!" Suzi states, her large muscles forcing her to reposition herself. You start to worry about Suzi's state of mind as she appears to be lost in the moment and her figure slowly starts to look unappealing to you. Thankfully her face is unaffected and it manages to keep you going.

As your cum nears your knees you stop your near constant stream and step out leaving Suzi to absorb what is left. You sit on the toilet and watch as Suzi gets larger and larger. You soon notice that Suzi has stopped rubbing the cum over her body and has instead moved both hands to her between her legs. Her head is tilted back and her chest is raising and falling rapidly. You take it as your cue and stop her growth. Within moments Suzi grunts her release.

You step over to the bath and offer her a hand, "There's no need," Suzi says politely. "I feel fantastic!" she adds as she stands and steps out of the bath. Your mouth is wide open as you take in her final form. All her muscle groups are clearly on display, bulging muscles everywhere you look, large shoulders linked to large biceps.

"I... I... I don't know what to say," you comment after what felt like minutes of silence.

"You don't need to say anything," Suzi replies as she grabs a towel and wipes off the excess spunk. Once dry she looks at her self in the mirror. "Perfect," she says with a smile. "Hey Hilda, you can come in now!" she adds. Hilda wastes no time in opening the door.

"Oh my god!" Hilda gasps as she takes in Suzi's new muscular form, hand over mouth to hide her gawking. "I... I..." Hilda starts to say.
