A blowjob onahole. You see the “mouth-form”, right ?
It is an evolution from a previous one, “Fera Master”. Greatly improved, actually. ToysHeart has some amazing history.
On insertion, your thing gets nicely wrapped between a ribby top and a rough bottom (with the sort of tongue). The more large part at the ending has it’s importance here, because when the air is pressed out, it produces a (welcome) suction effect.
The material is pretty flexible so it fits well for western people (even better: a greater girth better prevents air to flow in, and so it keeps the vacuum). Easy to use, easy to wash, less stimulation than a “vagina- onahole” but of course that’s not the point.
Just a thing: the entrance is pretty large and doesn’t have any “barrier”, so the lube spills quite easily. Better put some lube on your thing instead of pouring it inside if you don’t want lube drops (and stuff) on the floor or elsewhere. That’s up to you 🙂
Original and well-made toy, has a good ranking in my personal “best of”.
