To have a strong figure

"Lets go into the bathroom," you say, quickly thinking of the best (and most interesting) way to grant Suzi's wish. The three of you step into the bathroom and you indicate for Suzi to step into the bathtub.

"I want this to be a surprise for Hilda," Suzi said unusually shy. "I don't want her to see me mid-way," she added blushing slightly.

"Would you mind waiting outside?" you ask, looking at Hilda.

"Ok I guess I can play ball," Hilda replied. "I'll be in the kitchen when you're ready," she added stepping out and closing the door behind her.

"OK then Suzi, you ready for this?" you ask.

"As ready as I'll ever be, but why am I in the bathtub?" she responded.

"Well I was thinking I could make you stronger by having your body absorb my cum," you say matter-of-factly.

"Sounds like a plan to me!," Suzi said quickly removing her clothes and laying flat in the bathtub. You quickly whip out your cock and start to pump away. As you thrust away on your cock, you get into the tub as well standing over Suzi you watch her as she gazes at your cock, willing it to cum and start her transformation. A few minutes pass and using your powers you make yourself extra productive just before you shoot your first load of cum, splattering all along Suzi's body. Large amounts of cum land on her before quickly being absorbed by her body. "Mmm that feels great!" Suzi says as she rubs her hands over her cum soaked body. A few more spurts and you start to see a change in Suzi's form.

"I think it's really working now," you say breathlessly as you continue to run your hand along your cock's length. Suzi looks down at her body and sees muscle groups start to appear, slowly becoming more prominent.

"More, more, give me more," she pants stilling rubbing your cum all over her body.
