Straight out of the box they are pre-coated with powder to keep them soft so I recommend you wash it off with water before applying lube and using it for tit-fucking. However if you are intending to use this for groping purposes then they are ready to use straight out the box if you don't mind a slight powder feel to it. I personally enjoy the powder feel to it since the surface feels incredibly soft.
After washing the breasts with water then quickly move them to a cloth were a minimal amount of lint and hair are present since it easily catches does things due to a slightly sticky surface immediately after washing with water.
Apply a generous amount of lube to the breasts since in my personal experience it dried off quickly(FleshLube). Once they are lubed up they have a nice smooth/soft texture and are ready to be groped/tit-fucked.

Nipples: Very Soft and slight firmness
The firmness is the right amount to give a sense that they are erect and still be flexible/soft enough to play around with.

Groping Experience: Firm yet soft
(Lubed) I was hoping the breast would sink my hand with small amount of force/effort but that was to case. Once I groped them with what I thought was appropriate force I was greeted with firm resistance trying bounce back my hand. I was slightly disappointing since it was not what was I envisioning but it could still serve a purpose when aggressively groping the breasts since it can handle a lot of force.
When washing the breasts with water it will feel like the breasts need less force/effort for your hands to sink in.
When coating the breasts in Corn Starch the breasts will feel the softest they will ever be.

Tit-fucking(Paizuri)
I highly recommend applying lube before and occasionally during the session in order to prevent damaging the toy. If you use the toy other than laying it flat then you will have difficulty tit-fucking it due to the weight and lack of support.
However if you manage to have the breast laying flat and your using your hips to thrust(fuck) it then you will have no problems and you can play around with the breasts whilst in the action.
Either way the sensation of having the breasts embrace your cock is satisfying and personally with my 6 inches I was able to use it at it's fullest (results may vary).

Conclusion:
I am really satisfied with my purchase, the product was great value and if you plan to use this for "Paizuri" as it's part of the products name then you will not regret this purchase. However if you plan to use this for something other than Paizuri like groping then I recommend looking elsewhere for the best experience but this product still provides a pleasant experience when groping especially if you are a aggressive one. Shout out to Toy Demon for delivering it in 1 week, I am quite happy about the speed of delivery.
