The following is a short story about 2 women in a serious relationship exploring extreme fetish sex with themes/acts including expansion, cum play, milk play, nipple fucking, unrealistic sizes and anal sex.
---------------------------------------------------------------------------------------------------------------------------
Adaitha rested her arms on her huge tits. Each miniature blimp stuffed with fat, lobes, milk, and ducts lay on the ground in front of her. She idly rubbed her hands over the taut skin and enjoyed the sight of her own flesh extending out a couple of feet past her fingertips.
The top of each tit towered a couple feet off the ground even as their bottom 3rd flattened against it. The rest of her much skinnier body, minus her knees down to her feet, lay atop her ginormous stuffed belly. Filled with fat and food, her stomach was practically a personal waterbed lifting her up a little higher than the tops of her boobs. All of this, her boobs with their ridiculous torpedo shape, and her bean-bag chair of a tummy, were made possible by the brilliant body-mod spells she'd spent weeks crafting.
She adjusted her chubby thighs as belly-fat sunk between them into her aroused vulva.
She looked over at Tula and raised an eyebrow as the thin little bundle of muscle rushed over as fast as she could, giggling as her hard dick and cum bloated balls bounced enticingly.
Tula took the jar she'd brought with her and opened it. Then, scooping out a nice blob, she gobbed it onto Adaitha's right nipple before setting down the jar and lid on the nearby coffee table. Finally, she began massaging the cool lotion into Adaitha's hard nipple, gently, but firmly. Ada jerked unintentionally and let out a little 'eep' as her nipple tingled and became delightfully sensitive.
Tula shifted and smiled as she continued massaging before anxiously rubbing her thighs together and giving her lover a show of straining ball-flesh. Adaitha gasped and moaned. Both wanted to kiss, but Tula waited until the lotion was absorbed by nipple and areola. Then, cleaning any excess around the tip of her lover's boob, she stood up and came around to Adaitha's right side. They kissed deeply. Adaitha gasped into Tula's mouth as the lotion began its work.
Adaitha felt the tissues in her nipple widen as her central duct began to open up. Her swollen nipple seemed to almost glow with heat as the flesh grew and changed. The 1" 1/2 of nip lengthened to at least 2": Its width seemed to double as the once finger-shaped nipple jutted out and ballooned into a fat puffy ball, pinched in the center.
Ada chewed on her cheek as her fingers clutched at as much boob as she could. She ground her soaked labia hard into the belly-fat that inundated her crotch and moaned as an orgasm rocked her immobile body.
Tula stared slack jawed for a minute as Ada slowly came back down from her little climax, sinking into her three big cushions.
"That looked amazing!" She exclaimed finally as she looked over her recovering lover. "Everything good?"
"Yes," Ada answered. "That was great. Now to have you be a part of it..." She smiled devilishly and patted her right tit. Tula didn't need a second invitation. She stepped back in front of Adaitha's changed nipple, her cock achingly hard. She reached down past her huge balls and scooped out a nice amount of precum from her own vaj and slathered her dick with it. Then she made sure her lover was ready, before getting to her knees and aiming her dick.
Tula held onto Ada's big right nip with one hand while the other guided her dick. The moment the head first touched Ada's nipple was the hardest part: each received a powerful shock of pleasure and excitement that radiated through their bodies.
After taking a moment, Tula continued. She pressed her cock head harder against Ada's nipple until the widened central duct began to open around it. The head, slick with the precum, began to slide into the expanding entrance.
Tula closed her eyes, her sensitive glans sank in millimeter after millimeter. Her hips wanted to buck, but she held firm and continued to thrust, very slowly.
Ada for her part felt the extreme sensitivity of her own organs as the seemingly endless glans penetrated her nipple: the pleasure of the nipple stretching around her lover's head was delightful.
