Small breasts

When the cum was traveling up, Sarah saw that Adam’s chest was slightly bigger then they where supposed to be. Nothing impressive, or what can not be hidden easily, but that give her an idea, but before that she looked at the box containing the pills.

“Did you take the remaining pills? If yes, they had an interesting effect on you, and that gave me an idea,” Sarah said with a smirk on her face.

“Yes I took them, and what kind of idea?” asked Adam looking at his dick. It had not changed at all. What else would have happened to him?

Before Adam got his question answered Sarah grabbed Adams developing breasts. Maybe with the last few pills, and her cum, she can have more fun than she thought. Having a sister who would great her sucking her cock every morning was just as tempting as his brother doing it, but if he turns into a woman, and they get more pills, she may share him with Amy, both of them having big dicks… maybe all three of them, and playing with each other every day… but for that she need to test her theory.

“Now brother, do you want to be my personal cocksucker? Your job would be to relive every day, whenever I want, plus you would need to suck my cock every morning.” said Sarah with a seductive tone, while she released him, and grabbed her own breasts, and dick. “And maybe if your dick grows too, I may allow you to have your way with me… of course only if you reach something similar to me.” she said while she started to pump her hard member, what slowly released a little precum, letting Adam smell it, and almost even taste it, before she pulled a little back. “You have time to decide until I cum.”
