For one-on-one, MF sex, KK prefers female superior positions. She likes to control the depth, rate, and intensity of her partner's thrusts, and she likes to be in control in the general sense. There are a variety of female superior positions, including cow-girl, reverse cow-girl, reverse missionary, etc. that she enjoys. These positions are also amazing for a voyeur partner, with a penetration fetish.
I love watching KK squatting on the balls of her feet, reverse cow-girl, looking me intensely in the eye, while she's riding another man's cock.
Another of her favorites for MF is doggy-style. KK has very sensitive nipples, and when aroused, enjoys very deep penetration. Doggy-style accommodates a skilled lover with a big cock, and KK enjoys the feeling as her big tits sway during thrusts, rubbing her nipples against the sheet - especially if that sheet is satin or silk. She can have a "nipple orgasm" from that sensation.
