I finished this pretty quickly, as the story is only about 37 pages long. I'll give a pretty big warning: the story goes to sex very, very quickly, so if you're looking for something with a big sweeping story line, this probably isn't the erotica you want. This is very much a "small bites" type of short story/chapter and focuses on getting out lead character undressed and at the ready. If you want short stories that put more of a focus on story than sex, you might want to check out some works such as Alison's Wonderland. 
 Now as far as the BDSM content goes, it's fairly light. There is some bondage and Elle is spanked and slapped. It's not very hard, as the slap is fairly light and the ruler is only applied to her thighs. Content-wise, I'd recommend this for people who are just starting to get into BDSM but aren't really ready for the insanely rough stuff or the non-con type of play. It's all consenting at this point, although it might flirt with harder stuff and non-con in the future. It gives off a few of those vibes as far as the non-con goes. 
 For sexual content, I really enjoyed this. This story hits a lot of my kinks (office play, light control, etc), so this probably played into it fairly heavily. As you can guess from the cover, oral sex has a more dominant role in this book than vaginal or anal sex, although Elle has vaginal, anal, and oral sex in this book. 
 The only downfall is that unfortunately there isn't a lot of character buildup in this chapter. We're given a fairly rough layout of events and what to expect, but not a lot of development. (Elle falling for Cunningham, despite him being a "love-em-and-leave-em" type of guy, etc.) This sort of thing is to be expected from chapter erotica, but it will still leave some wishing that there was just a little more of the non-sex stuff to make everyone truly stand out. Comparisons to Fifty Shades will probably be inevitable, but even with the character development handicap the characters are still more likable than Ana and Christian. Not that that's difficult, mind you. 
 Now the price point as of this writing (2.99) will probably dissuade some readers. I'd recommend this piece, but perhaps as something you buy with your fellow erotica readers and perhaps loan each other on the Kindle. I'm looking forward to the author's future work, in any case.
