I sucked gently and flicked her nipple with my tongue then went to the other one. I went back and forth and as her nipples stood out even more, I got ...ore aggressive, sucking them hard and pulling away slowly. I put my hand down on Kate's leg and she shuttered as I moved my hand up to her crotch. As I sucked her tits, I rubbed her clit through her panties. After just a minute her panties bacame wet and she shuttered in a mini orgasm. Needging to cum as never before, I stood up and turned Katie. Jack did this a couple of times and allowed me to get the boat upright in varying winds. I proved to be quite competent. Following the dunking in the water, we were both soaking wet and Jack suggested we head for a nearby beach to dry off. As the design of the boat incorporated a self-draining hull, it didn’t take on any water and it was unnecessary to empty it out.

I see indignition in her eyes and I lose my temper. I slap her ass again and begin riding her hard. I drive myself into her, my office is filled with the sound of skin furiously slaping together. I grunt as I push into her tight little pussy. She loses her balance and her hands slip forward.
