I decided to leave the sci fi isle and took a succubus costume. The lady at the counter said I could change, and that the changing rooms were soundproof. Opening the package for the costume, I was greeted with a red latex skin suit, a red headmask with flowing black hair and horns. There was also a black lace lingerie set with clip-on stockings and eye contacts with yellow pupils surrounded by black. Taking off all my clothes, I decided to put the bodysuit on first. It had no zipper, so I slipped into it. It was a big for me, but before I could complain, a sudden wave of pleasure passed over me so that my breasts filled their place (a solid double G), my hips widened to match the suit, and so did my waist. "Amazing! What kind of technology can do this?" I thought. All of a sudden another wave of pleasure passed over me as the suit fused to my skin, connecting it to my nervous system. Concentrating, I managed to make my tail rub my breasts, making me moan. But before I got carried away, I remembered to nut the mask and contacts on, which created more pleasure as they fused with me. Then I took notice of how--accurate the costume was. It had nipples and a vagina. Squeezing my breast, I stifled a moan but was surprised when it squirted milk. Deciding it best, I put on the lace lingerie and clipped the stockings. I was about to put my shoes on but I took notice of something else in the box. 7" black heels and a set of lace gloves, along with a black choker with a bright red Gem. first putting on the gloves, then the heels, I finally put the choker on. As soon as it was tightly fastened upon me, the gem in the choker released a constant wave of pleasure, which lasted for several minutes. Moaning and writhing on the floor, I grinned. I was complete.
