Isuem's Elixir [Final] [CLEAR-ABYST]

If your tomboy childhood friend asked you for a special favor, what would you do?
Our heroine is Isuem, an old friend of the protagonist. She’s a total cutie who looks really good in men’s clothing! One day, she approaches our main character, Kcolraw, to help her with an experiment…
“Tests on Enhancing and Accentuating Titties… TEAT!”
Kcolraw agrees, and the experiment gets underway. It’s not long before the elixir she’s developed, helped along by Kcol’s ‘massages’, has her rocking the body of her dreams.
Isuem’s so pleased that she decides to give Kcolraw some blowjobs and a naughty little titfuck or two!
As the two get closer (and more adventurous), it begs the question… What’ll happen when the experiment comes to an end?​
