It continues.

As soon as Crystal noticed the makeup seared onto her flesh, it moved again. The sensation of the ink flowing through and on her skin was like nothing Crystal had ever imagined. In it's wake the ink left Crystal's flesh throbbing with sensation, her nerve endings raw. She couldn't tell if what she was feeling was pleasure or pain. The ink flowed down her chest between her breasts and back up around both of them. The ink spiraled inwards simultaneously over her breasts, whirling closer and closer to her nipples. Upon contact with those sensitive buds of flesh Crystal's body jerked with a spontaneous orgasm so powerful it hurt.

She braced herself on the sink, panting. She brought her hand up to her breast, touching the tattoo. A very familiar pain flared up where she touched, the feeling of the needle she had endured to get the tattoo in the first place. The message from whatever terrible sentience her tattoo possessed was clear to Crystal. She was not to interfere with the ink.

The ink flowed down and around to her back, over the shapely spheres of her ass and between her legs, rushing up over her pussy. The sensation was an onslaught, so powerful that she crumpled to her knees. She mewled in mingled pleasure/pain. The ink flowed around over her moist pussy again and again. She came again and again, sometimes more than once at a time. After her eleventh orgasm with the ink showing no signs of relenting, she began to drag herself to her bed. All the orgasms had rendered her legs useless.

She cried out as the orgasms kept coming. She was having trouble focusing her eyes. She heaved her oversexed body onto her mattress and faced the ceiling, panting like a bitch in heat.

Her mouth was dry, and could only gasp as the the ink kept coming, keeping her cumming. She passed out.
