Two Vials Tipped, Two Bodies Spilled [WM]

Nefer began panting as Lily literally used her body as somewhat of a sex toy, but she couldn't complain because not only were her breasts feeling the sensation of the large cock rubbing against them, but each time Lily thrust, Nefer's cock rubbed against her larger shaft, too. Their shared precum lubricated the motions well, making it even more attractive to Nefer.

This new cock was giving her sensations she had never felt before, and one look at Lily, past her cock, told Nefer that she was experiencing the same thing. Cocks felt good... Suddenly, Lily's hands shifted to Nefer's ass, causing her to squeak in surprise. Something brewing?.. So lame... Nefer used her arms to cup her tits tighter around Lily's cock, somewhat for her sake, but mostly for the mini giantess's sake, who was currently using her.

And, despite her pleasure and Lily's relentless thrusting into her, Nefer found herself close enough to a bookshelf to see two potions sitting on top of the shelf with Lily holding her up like this. Between thrusts, Nefer hastily grabbed both, popped their quarks, and downed them both before her hands returned to squeezing her breasts. And, right after she drank the potions, she turned to see that she knocked over two more bottles of glowing liquid, rolling to the part of the shelf closer to Lily.

Suddenly, she felt something within her new balls. She moaned loudly as her cock suddenly shot a large rope of pre past Lily's cock and right onto her giant sister's face. Not only that, but her balls almost felt... more powerful. And full... What did those potions do to her?..

Gasped softly as the spray of pre splattered against her upper lip and nose, instinctively licking her lip as It dripped down. Her eyes glazed over even more as she seemed to be savoring the flavor, "Mmmmm sis...you taste...divine."

There was a salty tang left on her tongue as she swallowed the sample and wiped the rest off with her fingers before placing them in front of her sister's mouth.

"Here have a taste."

Out of the corner of her eyes she noticed the two potions Nefer had knocked over. She smiled and grabbed each of them, "Oh perfect, something to wash my like treat down with."

She popped the corks off each and poured them together into her mouth before swallowing the mixed fluids.

Felt the potions metabolize inside her and couldn't stifle a cry as she felt a surge within her new balls as they stretched and filled with more cum, seeming to expand as her own thick rope of pre shot into Nefer's face.
