Gritting her teeth Jenny grimaced and gave him what he wanted; the lewd sight of her backside jiggling this way and that as he continued to spank it. His hand now felt like sandpaper on the sensitised flesh. How much longer would she have to endure this? The clamps continued to bite into her tender nipples, and as she swayed to and fro she could feel them moving with her, the ache increasing with each passing second....

If Jenny thought life was hard under the expert tutelage of Mark, being faced with a stable full of sex-starved pony girls poses several more challenges. For instance, how do you bring 11 young women to orgasm in a timely fashion? But to her surprise, tackling the problem with experimentation and enthusiasm, she finds herself enjoying the experience.

When training begins it is anything but enjoyable, however. Harnessed in pony girl tack, her body is encircled with leather, rubber and steel. It nips, chafes, and rubs cruelly, especially when she's faced with a morning of naughty games in the exercise yard.

In book four of Pony Tales, Jenny earns herself several punishments, and is subjected to some very thorough sex indoctrination she has to submit to the whims of her groom, trainers and even the stable-hands. Will rescue arrive or will she have to beg to be released, with nothing more than her body as currency?
