Sexperiments V: Family Bonds

The siblings had met again, and not a fiber of Morgana's being would believe that this was chance. Every month she came to Zaun for some of her more exotic ingredients, and Kayle had a knack for appearing at every chance to with another attempt at convincing her sister to repent. Stressed with Zaunite streetlife and cursing at her sister Morgana quickly strode through the town to her supplier Dr Mundo, as Kayle called after her from above, trying to reason with her to no avail.
Bursting into the room Morgana called to the large purple man "I need my supplies, Mundo!" as Kayle landed in the doorway, grabbing her sister by the shoulder. "Father would be overjoyed if you came back- we could even fix your wings! We have the technology!" "UGH YOU DON'T UNDERSTAND!" Morgana yelled into the air, swatting her arm out and accidentally flinging a beaker behind her, the glass cracking and spraying both her and her sister in the liquid. Silence hit the two as they stared at the bubbling liquid for a tense moment before it went flat and the two sisters finally met eyes before they felt their bodies begin to change. Feeling a tenseness in her muscles, Kayle's eyes shot open as her armor shot off of her like bullets her bulging mass easily breaking through the ancient armor. Her body grew to two and then three times the size it was originally. Her rippling muscles were made all the more imposing when she looked to her sister who had become at least three times the woman she had been before, huge swaying breasts matching her fantastic hips, as she became the contrasts to Kayle's distinctive masculinity. Before they could say a single word in complaint, however, they were all over each other frantically ripping what was left of the others' clothes off of their bodies. Morgana didn't disappoint, her soft pillowy breasts as supple and responsive as ever, as a moan rose from her mouth unwillingly. "Wh-why.." she began before she found herself liplocked with her sister, who very skillfully pinned her to the admittedly dirty floor of Mundo's lab and began working her tongue across Morgana's body. It was like a dense fog rolled through the woman's mind, Morgana moaning pitifully as Kayle moved down, before probing her tongue into the woman's hot and wet snatch, exploring every inch. Straddling the woman, Kayle smiled down at the woman who was at the mercy of her bulging muscles, "I WILL convince you sister, one way or another."

In the next room, Mundo was glued to the screen of his security system, watching the sisters go at it wildly. "MUNDO CUMS WHEN HE PLEASES!"
