Strum: Virgin Captive of the Billionaire Demon Rock Star Monster — Cari Silverwood

Yet another erotic parody where a light is shone on all the dirty, crazy, squishy things dwelling in your romances.

When a stag party goes terribly wrong, Virginia Chaste loses her memory of all the best bits of her fiancé, Karl whatsisface. She awakens with her tongue stuck to the castle floor, a suspicion that someone kissed her, a missing fiancé, and no idea what will happen next. Luckily Dangerous Bob can show her the way.

All she has to do is join Zagan Grimm, rock star and demon, he of the radioactive cock, to retrieve the ultimate sex book, the Necrosexi-texmexicon, from the depths of the Zon, then she can get her fiancé back, even if she'd rather sell his castle and make a million dollars.

Then she absolutely has to remember not to have a spectacular, tentacular ménage with Zagan and Karl whatsisface.
With so many things to remember, Virginia may forget the last one.

Yes, a big, fat warning to all those with pristine, well-vacuumed minds: Here Be Tentacles.
