Previously, I had reviewed several onaholes. An onahole is a portmanteau of the words onanate (masturbate) and hole. So an onahip is literally a hip to masturbate with. Step-Sister’s Secret Relation is such an onahip.
What is the Step-Sister’s Secret Relation?
This sex toy for persons with a penis is shaped after the hip of a woman with a vagina and anus. So two tunnels where you can insert your penis. Of course, the tunnels have different textures.
The hip is made of extremely soft material and the buttocks are wonderfully malleable and large enough to peck nicely. Because it is a whole hip, the thing is also quite heavy.

Unboxing
This Step-Sister’s Secret Relationship onahip comes in a cardboard box with a design on it of a typical manga style schoolgirl. There are images of the onahip on 5 of the 6 sides, giving you a clear picture of what you are getting in advance.





After opening the box you will find the onahip in a clear plastic blister, where you could keep the onahip even after use. The onahip is further packaged in a hygienic bag. And a small bag of water-based lubricant is included for first-time use.
Taking the Step-Sister’s Secret Relation onahip for a test drive
I haven’t said it yet, but … what is this fascination with stepsisters? I have absolutely nothing to do with them. Why would you want to fuck your stepsister? And what kind of message does that send to the stepsisters among us? Really, as far as I’m concerned, that whole genre of stepfamily incest porn should disappear immediately. Then again, that’s just the name. And finally, I don’t necessarily fall for the whole schoolgirl fantasy genre either.
Of course, the most important thing is just whether it’s a little nice to masturbate with! And … it certainly is!




The hip has no real bottom. I mean, it’s not like ‘she’ always has to lie on her back or on her stomach. And the ‘flesh’ of the buttocks is really wonderfully soft to grab onto. That and the hefty weight of over 2 kilograms (!) make for a wonderfully hard grip on these hips.
As you would expect, the vagina entrance is wonderfully soft and deep. The structure massages your penis in a fine delicate way. And then there’s the anus. That one is a lot tighter and yes … I love that. But what is especially wonderful is that with one toy you have two delicious holes to pamper yourself with.
Cleaning
It should be obvious that you don’t just turn this onahip inside out to clean. The only (proper) way to clean it after use is to run lukewarm water into the holes to rinse it thoroughly. Therefore, it is definitely recommended to order cleaning sponges and drying sticks along with this masturbator.
Conclusion
This is a delicious masturbator that is large enough to serve as a sex doll, yet still small enough for easy storage. You get two delicious fuck holes that provide fine variety. You can do nice varied positions with it. And the material is nice and realistically soft.
The PROS van de Step-Sister’s Secret Relation onahip:
- Delicious ultra-soft material that is nicely malleable
- Realistically designed
- Two holes that are different in sensation and texture
- Deliciously heavy
The CONS:
- Go away with that stepsister fantasy of yours anyway!
