A Taste Test Gone Wild [WM]

Nefer licked her own precum off of Lily's fingers without hesitation. "Oh wow, my pre does taste better than I thought it would~" She responded. But then, she saw Lily go for the two potions she knocked over. Her sister didn't need any more!..

Nefer didn't get to protest, nor did she try as Lily drank both potions. Nefer looked down to see Lily's balls literally expand, slosh, and convulse from the potions effect. Not only that, but one of the potions Lily drank seemed to be the same one Nefer got because Lily's large cock shot pre instantly onto Nefer's face just like Nefer's had a moment ago causing her to flinch.

Nefer licked her upper lip and tasted Lily's pre. "Strangely sweet..." She muttered, wiping it away with her hand and smearing the excess on Lily's cock to act as more lube. And, despite their little potion break, Nefer was still on the verge of cumming. "Fuck... sis, I..."

She started panting heavily as her cock become more erect and engorged against Lily's cock. However, Nefer didn't get another word before she began thrusting against Lily as orgasm took her. She groaned, moaned, and mewled as she came on the underside of Lily's shaft, her cock throbbing powerfully despite its smaller size, covering the larger cocks underside with her white cum in spurts.

Lily heard Nefer whimper to her before her voice broke into a series of mewling cries and grunts as she came. The bigger girl felt the warm sticky feeling of her sister's cum coat the underside of her cock as she smeared it across Nefer's tits as she continued to rub her cock through them.

Her tongue rolled across her lower lip as her eyes rolled back, "Oh goddess that's-."

Her entire body shuddered as her balls churned and tightened, with her cock spasming as her own orgasm ripped through it. Not only that, but her load oozed from her cock head more than shooting out, but it still reached high enough to splash across both their chests.
