Analingus

Vivia lay on the rock island amidst the flowing stream, propped up on long, unfamiliar arms to glare impatiently at her own, nude body as the one who possessed it played with her legs. She shifted her hips slowly, taking delicate steps in a small circle.

“Before I return your body,” the ex-mermaid drawled, bending forward to caress her legs, “I'd like to feel its rear serviced.” Her head of red hair turned sideways as she slid a hand up to her hip, an expression on the face that Vivia never knew she could make—one both devious and lustful. “That tongue felt so good elsewhere, after all...”

Vivia felt her new body's face flush, working her mouth with a frown as she swallowed nervously. The tastes on its tongue still lingered from its previous activity. She considered the request reluctantly, figuring if she got her own body back afterward, she wouldn't have to deal with the taste too long.

“Fine,” she growled. It came out more delicately than she'd hoped. “As long as I get my own body back afterward.” She struggled to sit up and put some authority in her posture, but only succeeded in slipping her tail aside awkwardly.

The ex-mermaid smiled in a way that seemed strange on her face, and slowly knelt to Vivia's level. “You shall, as long as you perform well.” She crawled over, turning around to present her body's rear to Vivia, knees splayed wide. “Service it earnestly, and don't be shy...” she moaned, casting a sultry look over her shoulder.

Vivia ran her new tongue over foreign lips, eyeing her own body kneeling before her. She knew she was good-looking, but like this, she was positively erotic. What effect lust had on this mermaid body was a mystery, but she certainly felt a growing heat inside it. Tentatively, she leaned in toward her former body's ass, grateful that she kept herself clean.

Pressing her face against her cheeks, she extended an exploratory tongue, lapping at the space between. The ex-mermaid arched her back, pushing herself closer as she murmured lustfully. “You'll need to want it more than that...”

Vivia lifted a hand up to one cheek, soon requiring the other to grip her former body's hip for balance. The excitement of the mermaid body was concentrated in its nipples, and some frustratingly absent space below the stomach. She understood how badly the mermaid desired a pussy as she squirmed with that feeling, breathing a hot moan on her own body's rear. It escaped with a musical tone, and she delved her tongue back into her work.

The ex-mermaid reached a hand between her legs, fingers dancing around her pussy as she tipped her head back with a moan. Vivia pushed her tongue against the puckered hole until she felt it relax enough to admit the probing appendage entrance. She found it easier to endure the act than she first anticipated, and tried to be as earnest as the bitch desired.

Soon she was growling her moans against her own asshole, feeling it spasm around her tongue. The ex-mermaid writhed on her knees, freely venting her cries of ecstasy. At the climax of Vivia's moan, she almost felt the sensation of her own body once more, an itch between nonexistent legs being scratched momentarily. A hitched gasp later, and the ex-mermaid was groaning with satisfaction as her shoulders slumped down toward the stone, forehead lain on a tanned forearm.

Still, her rear wiggled against Vivia's face despite an apparent orgasm. Vivia began to grow impatient, believing her work sufficient and awaiting her promised reward of her own body returned. As the ex-mermaid caught her breath, though, she didn't seem ready to give it up yet. Vivia was nowhere near satisfied, and wondered whether she should demand it, or see if she could get back to that moment of feeling her own body again.
