Kim must have heard the exasperation in your voice and cramped once.
You walked back to your room, a little unsteadily both due to the heels and the martini which hit you much faster than you'd expected. Dropping your purse on the floor as you closed the door behind you, you walked over in front of the mirror and smiled. You were already feeling flush from the drink and the dance. God Kim looked fantastic in this dress. You had an idea. You struggle a bit to unzip the back of the dress, but then let it slowly slide down your body while you watched in the mirror. Your hand cramped as Kim was apparently also enjoying the little striptease.
Standing there with just your underwear, you decide to keep the heels on as you run your hands down your nylon covered leg, both enjoying the feeling that you always do of running your hands over a woman's nylons, along with the new sensation of having hands roam over your own smooth legs. You slowly trace your left finger up your thigh until you reach your crotch. God you're soaking wet already. You start slowly massaging Kim's nub through the pantyhose while your right hand moves up to your bra and cups your left breast.
Watching the hot girl in the mirror play with herself along with your new sensations and you quickly bring Kim's body to climax. You feel your whole body convulse and you sink down to your knees as pleasure washes all over you. "Are you cumming too honey?" you ask and you hand cramps slowly but firmly in response.
Your legs feel like jelly so you step out of the heels and hoist yourself up onto the bed. You unhook your bra and let it fall onto the bed as you roll over onto your back and peel off your panties and hose. Now completely naked, you resume your massage of Kim's body. Unlike when you didn't have the Kim suit on, you feel like you're ready for another round already. Kim's (well really, your) pussy is so wet your fingers glide over it and your feel it open up a little as they graze by. You slowly push a finger inside, reveling in the new sensation of having something inside of you. You push it in deeper, amazed at the feelings. "God, " you thought, "if a finger felt this good, what must a real cock feel like?" For just a moment, a picture of Alex hovering over you with his cock buried deep inside flashes into your head and you instantly climax again.
Thank god Kim can't read your thoughts you think, as you come down off your second climax and drift quickly off to sleep.
