Play with me a little while you are moving to straddle me, to bring your body above mine. As soon as your hand is around me, I will start raising my hips, trying to fuck your curled fingers. You smirk, and keep your hand open enough that I can't really get going. Let go of me as you climb over my thighs. I'll moan a little in frustration, but when I open my eyes again and see that you have taken the bottle of oil from the night stand, I'll wait, quiet and eager. My eyes won't miss a drop, won't miss an inch of your sweet, wondrous body.
Take some oil in your palm, warming it there, and slide that hand down your body. The waning rays of the sun catch the slick trail you are making from your breasts down the joyous curve of your stomach; inch by inch, make your body glisten for me. Wipe your hand down my own chest until you reach my cock, and give it any leftovers. I know what is coming, so I won't move yet.
Now come down on top of me and kiss me. Kiss me hard, lover; kiss me until our teeth clack together and we can't breathe. Squirm on top of me, slippery from the oil. Let my hands move across your body once, but then move them down to the mattress. Look into my eyes and smile at the lust you see there. Wriggle against my cock and say, "I know what you want." You know how I'll moan in reply.
