Hana gulped, feeling something contort in her stomach.
Yesterday she fell asleep in the lab and woke up horny and angsty - when she went home that night she masturbated over and over, coming at least a dozen times. Today she came to work groggy and feeling hung over, but as soon as she spent a few minutes in the lab she started perking up. She touched her erect nipples, felt the sweat building up on her skin.
Drool started to spill from her mouth. It felt slick and viscous. Hana's eyes were half open, she felt another kick inside her, this time from lower in her body. She stood up from her chair and tried to make her way to the door - she needed medical help, that much was clear. Why was she the only one in the lab today?
She coughed, and a large batch of lubricant welled up inside her mouth, followed quickly by a massive phallic member snaking its way up from her stomach. It squished itself against the side of her esophagus, letting her breath as it slithered up to spar with her tongue. She could feel the member as if it was her own body - and it felt like her massive tentacle cock was fucking her own mouth from the inside. The cock erupted from her lips, spilling precum and lubrication down onto her breasts.
Hana began freaking out. Internally. Externally, she was on the verge of orgasm and her eyes were rolling up in their sockets. Her vision was blurry - her glasses began to fog up, and everything around her began to descend into a pink haze. Hana fumbled around the benchtop to find her cellphone, trying desperately to call for help. That's when the parasites in her lower holes emerged.
The werm in her pussy burst forth, finding the soaked fabric of her panties, and wheeled backward through the fold of her crotch. The werm in her ass did the same, pushing forward to her vaginal folds. The parasites squeezed past each other to penetrate into opposing orifices. Hana felt the entire process of her two new phallic members fucking both her lower holes, and collapsed to the ground moaning in pleasure. The phone bounced away across the tile. Her mind began to break as she lay on the floor, molesting herself in a pool of sweat, cum, and lubricant, fucking herself in all her holes and spewing jizz all over the ground. Horror gave way to a new deep sense of satisfaction at the feelings and sensations she was experiencing.
