Jo turned off the shower and started to towel herself down – getting ready for her night shift as a nurse on the ward. She dried her short brown hair then moved down the rest of her slim five foot body. Not bad for fifty, she thought, and with nice big firm pointy tits – as her husband liked to point out. Her pink nipples began to harden in the cool air and she lingered over them with the towel for a few moments.

She then reached into her bag for her scissors, sat on the bench in the changing room, spread her legs and began to trim back the hair around her pussy lips. She was under strict instructions from her husband to keep that area nicely trimmed back at all times – he expected a good view and easy access. He’d been away for a few days and would be back the next evening – she wanted to be ready for “inspection” and the good hard fucking that would surely follow.

Failing an inspection would inevitably mean a spanking – not that she minded that, but she wanted to present well when she was bent over the chair. He’d find another reason to punish her if he needed one. He’d also threatened more than once to send her to her beautician Sally for a full shave. She had mixed feelings about that but the thought did make her oddly excited – she wondered what it would be like to have another woman touching her so intimately.

Jo had been curious about sex with another woman for a while. During her last massage Sally had more than once just gently touched the side of her tits and Jo had felt the start of arousal. She’d wondered at the time whether to ask, “Do you want me to turn over onto my back ?” but had lacked the courage. Later she’d fantasised about how good a tit massage would feel and how she’d enjoy masturbating while Sally watched.

As she clipped back the wiry dark brown hair she felt herself getting wet, her lips getting puffy and engorged and her clit starting to harden. She not had time to masturbate for a few days and she was starting to feel an irresistible urge. She finished her trimming then quickly moved over to the door to check that it was locked – turning the catch to the left to check, She put the scissors back in her bag and retrieved the little “pocket rocket” vibrator she carried for such occasions.

She knew that Sister Julia was a stickler for punctuality – but it was twenty minutes before the start of her shift, just enough time for at least a couple of orgasms to tide her over. Not as good as the full hour or so she would spend if she was in bed at home with her “rabbit”, but better than nothing. Also no time to call her husband to ask permission. He approved of her masturbating but insisted that she always ask permission first. Still the spanking that would follow her confession would be worth it.

She moved over to the chair in the corner of the room, bent over, spread her legs, switched on the vibrator and applied it to her pussy lips. The feeling was wonderful as she moved the tip up over her clit, varying the pressure rhythmically to build up the sensation. She worked down either side then moved the vibrator back into direct contact, pressing down hard on the swollen little nodule that her clit had become. She was soon gasping through her first orgasm, trying desperately to keep the noise down but finding it impossible to be completely silent.

The orgasm lasted around a minute and she eased off a little to begin the build up to her second.

Then she heard a key turning in the lock and the door beginning to open...
