As June fondled her tits in the mirror she found mounting lust burning through her body. She had always wanted huge tits, those dinky little C cups had never been enough, and now her bosom had swollen past the size of two basketballs and was still surging forth little by little. Her nipples, grown bigger too, pressed out as she grew horny. She hefted her orbs in her hands and marveled at their sheer size and weight, how they squeezed like soft but firm pillows.
June kicked down the toilet seat, her tits bouncing with her movement, and sat down. She looked down at her chest, which was quickly approaching beachball size, and an evil grin struck her lips. "I've always wanted to do this..." She gasped, and proceeded to raise her massive left tit up to meet her mouth. She easily had the size to reach her lips, and they closed hungrily on her nipple and areola. With wincing eyes of pleasure, June began sucking her huge still growing breast. Her boobs continued growing as the woman got hornier and hornier. Soon she was wet between the thighs and aching for release from the sheer excitement. Panting, she released her enormous nipple from her mouth and greedily hugged her arm against her ballooning rack. With her free arm, her hand quickly plunged between her legs and into her eager pussy.
As she masturbated frantically, June continued to expand. She gasped as she watched, feeling her orgasm mounting and watching her chest surge. Sitting as she was, her soft breast flesh filled out to cover her legs. Outward and outward her breasts grew, each nearly the size of June's torso. She gasped, relented, and felt her orgasm explode, which only served to enhance the sensuality of her growing tits.
As the feeling subsided June opened her eyes in shock to find her boobs still swelling. Carefully, she rose from the toilet seat, supporting each enormous and heavy breast under the respective arm. The weight was incredible, as were the sensations from her soft swelling. The bigger her breasts became, the more incredibly and deliciously sensitive they became. She stood in front of the mirror again, suddenly alarmed at their size, and her jaw dropped as her face was becoming obscured by her giant tits.
