We stand up, but as you’re about to start walking off, I wrap my arms around your waist from behind and pull you back against my chest. You place yo...r hands on mine and lean back into me. I rest my lips next to your ear and whisper ‘time to cum’. You bite your lip and moan quietly then follow me back to our dark hallway. You press your back to the wall, cross your wrists above your head, and spread your thighs for me on your own accord. I stand in front of you with a slightly raised eyebrow. "Hehe thanks! Not as big as nice as you're booty though" just then she said, oh you have been looking at my ass?! I nooded a yes.. I then said, i always liked your ass.. I've had fantasies about your ass, she looked at me and said, "oh really.. Like what?!" I told her how i always wanted to be her little slave, her slave she could facesit, and tie up and tickle and make me be her personal toilet and i went on and on, she then stopped me and said, wait you're in luck! I stood there in shock. I explore you with my tongue, feel you squirm under me. I want you relaxed before I move on, so I take my time while I open the lube and drizzle it on a finger and then over your balls, letting it drip. I slowly start to replace my tongue with my finger, running in smooth circles over the outer ring, massaging you, getting you used to some pressure. My finger traces your ass for several seconds, and then I look up at your face. One lubed hand squeezes your cock and my slick finger slowly pushes. Relieved at the break in tension.“Why are you embarrassed by your body?”“I - I’m not,” I said.“Why are you covering up then?” she asked. “We both have the same fixtures and fittings. It‘s not as if I don‘t know what a pair of tits look like.”“I suppose not,” I said.“And I have a cunt too.”I blushed. I had never used the word outside of sex.“Look. Does this make it easier for you?” she said and hitched herself up onto the work surface, her legs spread apart. She really was a beautiful girl.
