I went to Florida several months ago. I was quite happily swimming around with the dolphins when she suddenly decided to grab my foot with her genital slit. Dolphins have very muscular vaginal orifices, and can use these muscles to manipulate objects and carry them. I stayed still for a while, to see if she was just playing, but she continued to masturbate against my foot, and in the light of the torch I sometimes carry, I could see that her slit had become very pink and had swelled as well. She was aroused!
So, I started to back-paddle with my hands towards a small beached area, partially submerged in the water. A couple of times she pulled me forward into the deeper water, but eventually I got my self to the shallows. I dislodged my foot (Being careful not to pull too hard), and took her gently by a pectoral fin and rubbed her belly just to aclimatize her, I guess. She immediately rolled belly up and started doing pelvic thrusts against the palm of my hand. It was unmistakebly erotic, and by now I was fully aroused.
I stripped off my shorts, and gently pulled her into the shallows until she was lying on her side, her belly facing towards me, half submerged in the water. I nestled myself belly to belly against her, and pressed my member against her genital slit. She immediately arched her body against mine, and took me inside her body, initiating a quick series of muscular contractions with her vaginal muscles. I wrapped my left arm around her body and just held her close while she manipulated me inside her body, until I climaxed barely 2 minutes later. Surprisingly, her body also shuddered against mine, and we spent the next 5 or so minutes just lying together in the shallows, hסlding each other, enjoying our company and revelling in the fact that we had shared something special together, something very few people can claim to have done.
