Its shocking and disgusting, but also a joyous farce. Every inhibition gives way to the ultimate goal of physical pleasure, and in this book, theres a lot of different ways to achieve that goal. Thankfully, there are no animals involved, but almost every other taboo is broken. Its amusing to read all of the various euphemisms and analogies used to describe the sex in great detail.
The story of a mans sexual trysts with his girlfriend, then her younger brother, and then all three of them together. Explicit sex scenes without the cuss words; lots of coy, flowery euphemisms of intimate body parts and sexual activities.. oh, yeah, he also gets seduced by the girls fiance. Not advised for children or people of high moral fiber (easily offended by depictions of moral depravity).
The whole thing is completely ridiculous, but thats why its able to be so much fun. And I have to say, there are parts where you forget to be disgusted, and its pretty hot.
