The whole idea behind this onahole is that it (or is a masturbator a ‘she’?) is hidden inside a book: a secret magic book! That way, you can safely hide this Japanese masturbator in your bookcase.
What is the Secret Spell book?
The Secret Spellbook is an onahole hidden inside a book. Or while, a masturbator that you can easily hide in your bookcase, like your grandfather might have done with a bottle of whiskey in a hollowed-out Bible?
The onahole itself is designed as a doll of a naked female body. A mini-sex doll, as it were. Not one you have to lie on, but one you can hold in your hand.

Unboxing
The packaging of this onahole totally puts you in the magical atmosphere of Japanese manga and anime. Because the packaging is a book. The ‘book’ looks like an old spell book that could have walked right out of a magical story about elves and witches. It is a feast for the eyes!




Upon arrival, the onahole itself comes in a hygienically sealed bag made of recyclable plastic. It also comes with a sachet of water-based lubricant, which is enough for your first use. This lubricant, by the way, is the Seiraku OnaEki, which you can also buy in a bottle and is recommended for this kind of onahole. The book itself contains another nice manga image of a witch on the inside, explaining (albeit in Japanese, but that’s what you have Google translate for) the different internal magic zones of the onahole. A number of drawings inside the book illustrate this.

- Bewitched beginning: The opening is shaped like a vulva. The inside is red in colour giving it a more lifelike appearance.
- Witch’s Whim Spot: This area contains intense bulges.
- Spellbound stretch: A tight tunnel.
- Final Urge Gate: Even more stimulating nubs
- Chamber of Charms: Stimulating texture for the head of the penis
The test drive
At just over 800 grams, the onahole itself is no lightweight. The second thing that is immediately noticeable is that the tunnel is very tight. Fortunately, the TPE is very stretchy, but it does require you to have a pretty hard erection that is not too large in circumference to enjoy this onahole.

I find the weight and size of this onahole a plus on the one hand, as it sits wonderfully in the hand and is pleasant when moving up and down. On the other hand, the ‘body’ at the top is top-heavy, so you actually have to hold it with two hands to prevent it from swaying back and forth.
I think the internal structure is heavenly. There are a few thickenings inside that are very helpful for stimulation. And because the thing is pretty tight, it makes you feel like you are being sucked off.
Cleaning
Cleaning this onahole is not easy. The ‘body’ is too hefty (no body shaming intended 😆😉 ) so you can’t turn the thing inside out. Also, the tunnel is too tight to rinse it out easily.
It is therefore recommended that you also order cleaning sticks with this onahole. These are a kind of sponges on a stick, specially designed for cleaning the inside of an onahole.
Let the magic spellbook dry thoroughly before putting it back in the box. The cardboard will become much less attractive if there is still moisture running out of the onahole.
Conclusion
The Magic Spellbook is a very fine onahole, which – if you like it – also adds something magical. The input channel is nice and deep and tight and has a stimulating texture.
The Secret Spellbook’s PROS:
- Soft and flexible material
- Two-layer TPE making it appear ‘more real’ and making the internal structure easy to feel
- Tight tunnel
- Nice magic design of the packaging, allowing you to hide it under cover in your bookcase
The CONS:
- More difficult to clean
- Top-heavy, requiring you to hold it with two hands
- Tight tunnel requires a hard erection (not very suitable for men with a hefty penis or with erection problems)
