Lucy was eager to get herself home so she could pleasure herself to the thought of what she'd just done. She rushed to her car, dumping the new bag of goods on the passenger seat.
Even while driving, she was finding it difficult to keep her hands off herself, finding her left hand rubbing her crotch between gear changes. She was getting so desperate for release it was getting difficult to focus on anything else. It was even exploring ways she could get another dose of cum tonight. Maybe Sam would want to go again, or maybe Mike, or even the married guy next door...
Lucy day dreamed until she got home, swiftly hopped out of the car, grabbed her shopping and ran inside, locking the door. She immediately stripped down, one hand rubbing her cock while the other rummaged around in one of the bags pulling out a box. Ripping it open, she pulled out a reasonably sized vibrator, around 5-6 inches in length. She was already so horny she came just from looking at it, which proved useful in lubing it up. Squatting slightly, Lucy positioned it at the entrance to her ass, and slowly pushed it in. Despite being quite a bit bigger than the toothbrush, it still went in easier than expected.
Then Lucy clicked the switch, and found it was also far more intense than the toothbrush. She crumpled to the floor instantly, insatiable moans forced from her lips. Her left hand kept jerking her cock while her right went to her breasts. They already felt bigger than the bra they were in. She unclipped it and let them bounce freely as she thrashed about on the floor.
Lucy laid on the floor enjoying herself for an hour, and could have sworn that with each successive orgasm, her breasts were getting even bigger. It was definitely getting more difficult to see the rest of her body past them.
Once she was done and cleaning herself up in the bathroom, she investigated. They still just about fit in the C cup bra she bought, so they'd completely slipped over B. The rest of her torso and arms had feminised now too, softening out with sexy curves. Her face still had a little way to go though, she suspected, but her hair had grown out more, reaching her breasts. To anyone that didn't know her, she was a woman, but people that would recognise Lucas might still see the similarities.
