This Is Why We Do What We Do – emails like this…

I just recently received my Masturbator V with sheath. Before I ordered this product, I had tried tucking and it was painful for me. I was getting very frustrated that I was unable to  completely dress as a woman. As a transwoman, being able to dress as a woman and passing is important to me. I immediately put on this vee string and was amazed. I FELT and LOOKED like a woman. I closed my eyes and reached down, and felt the genitals I am supposed to have!! I wore this all day and even to work!! I love this product and highly recommend it to any transwomen or CD’s out there who want to appear fully female without the pain and hassle of tucking!!!

Fulfill your female illusion with the Vee-String Female Vagina Prosthesis© from Castle Supply.

The Vee-String has been in production since the 1980’s and online since 1998.  We are proud of our reputation and take great care to provide you with the highest quality latex vagina product available.  Castle Supply is located in the USA and all products are made by hand (no machines). There are thousands of combination possibilities, therefore, it may take 2-3 weeks for shipping of your Vee-String Female Vagina Prosthesis©.  Throughout the time it takes, you can rest assured we are working to complete your Vee-String to your specifications as quickly as possible.

When you buy a Vee-String Female Vagina Prosthesis©, you will receive a one-of-a-kind piece of art which will help to fulfill your feminine illusion.

One of our first customers, Robin, tells us:

“When I wear my Vee-String, the latex warms up to my body temperature and it becomes like my skin.  It is thin enough to allow the feeling to come through to my skin. I experience sensation where I rub.  I have had my Vee-String for years and it still works just like the first day I got it.  I’d say it’s durable and long lasting.  Bottom line, I get just as much erotic pleasure from the Vee-String as my partner.”
