Missive by J & e (BDSM 24/7).
Big disclaimer: The following is based on our experience only. Neither of us claim any special expertise or knowledge.
Breast pumping and labia pumping are not painful. After the cylinder has been removed pumping is not generally physically intense for the person who has been pumped. And, the sensation is much more subtle than it looks. However to the touch or tongue it feels fantastic.
When e is pumped and the vacuum is strong an intensity can build. However, it is not so much painful as uncomfortable. The only time e finds it as intense or painful is at the beginning if pumped too fast or when, after a long while of being held under vacuum, there builds a soreness and discomfort, which is almost immediately relieved upon release of vacuum and removal of the cylinder.
It is important to not over pump initially, because the full effects of the pumping is not felt immediately. There is a delay as the vacuum continues to slowly draw tissue into the cylinder – for e, this is an interesting and somewhat pleasurable sensation and can last from a few minutes to upward of 10 minutes.
For e when the vacuum is released on her labia there is not normally a great deal of sensation aside from the actual release of the vacuum and removal of the cylinder – her pussy is somewhat desensitized by that time. However, to the touch (hers or mine) it feels very good to the hand and to my mouth and tongue.
Tits nailing is a form of SM edge play involving hammering nails through the breast. Of course it hurts much more then play piercing because of the size of the nails, and also the hammering. But it can be done probably with a minimal amoung of pain. It is safe if done with care and forethought, with proper before and aftercare (antiseptic and keeping the wounds clean).
Nailing releases a flood of endorphins. And a lot of the thrill for both sadist and masochist comes from the picture in the mind. There you are held to something by your tits, you can’t move away there is a certain power in this for the sadist, and a total submission on the part of the masochist. There is a particular emotional/psychological dimension to driving a nail through a submissive’s breast or nipple that may be different in its primality and in its intensity from standard needle play, just as there is a difference, even, paradoxical or enigmatic as it may sound, a difference in intimacy, between the typical techniques of standard needle play and pushing a needle full-length into a girl’s nipple from the top or skewering her breast with a longer needle. Remember, it is never done without talk first with your submissive.
The nails used should be smooth and sharp. Infection is the biggest risk here. Therefore the nails used should be very smooth, with no microscopic debris that may be left in the breast. Ridges and twists found in many nails are good places for bacteria and other organic material to linger. Scarring is dependant upon a number of factors including, but not limited to, the particular characteristics of the flesh, any sort of stretching that’s done and the size of the nail. We recomend using small diameter round nails, like finishing nails perhaps (not screw nails).
Clothespins can be a wonderful addition to BDSM play and are relatively easy to learn how to use. Many new comers to the BDSM start with things like clothespins. Clothespins are usually used to give the sensation of pain to certain body parts. They can create many sensations and even increase the intensity of orgasm. With some caution and imagination clothespins can be used in any number of deviously enjoyable ways.
Most frequently, clothespins are used on the tits, especially on nipples. Clothespins can be placed on the nipples in many positions. You can start from clothespins pointing straight onto the nipple, not from the side, gripping the base of the nipple, not the tip. This does not have the same sort of ‘bite’ as grasping the nipple alone may, and often does wonderful things for sensitivity without causing pain. Pointing straight out is an especially deviant way to clothespin your partner.
