I trailed my hands back along her arms, over the balls of her shoulders and down either side of her body to her ribs. From there the they circled to her front and cupped her beautiful full breasts. She inhaled deeply and pushed her chest forward, maximizing the contact.
I began to massaged them as I leaned forward and kissed along the top of her shoulder from the outside working back towards her head. Looking over her shoulder I could see her gorgeous body reflected in the inky glass off the inky blackness beyond. She was delicious to look at and seeing her naked, knowing that she was facing out for all the world to see, but I was the only one to touch her was turning me on no end. I sucked lightly at the nape of her neck before raking my teeth across her skin causing her to whimper. She dipped slightly as her knees wobbled but I held her up, pressed back into my torso, still massaging her breasts.
My right hand started to slide down her abdomen towards her beautiful pussy. She kept it neatly trimmed with a soft down of hair just above her lips. As my fingers reached that spot I played lightly with her mons before dipping a finger forward to slide between her swollen lips. She was drenched and the feeling of her essence on my fingers caused me to groan as my body responded in kind, instantly flooding my underwear. My fingers ventured down to tease her opening and then back up to tease her clit, back and forth, rubbing and teasing almost thrusting along her valley with just the very tip of my middle finger dipping into her. She was moaning every time I got to her opening and each time to volume grew and then receding again as I withdrew back up to her clit.
This time my fingers stayed and started circling her button, sliding around in her arousal hoping that I was building her up into a minor frenzy.
My left hand dropped away from her breast and came around to my own belt buckle. I eased it open and then undid my pants, pushing them and my underwear down to hook below the toy that I already had strapped on. It was not a large phallus, maybe 6 inches at best but it was of the best black silicone with a decent girth. I adjusted it to sit up instead of laying alongside my leg. Angling my hips just right I dipped my knees and let the tip graze round the entrance to her honey hole. I heard her gasp as she felt the tip coating itself in her copious juices and realized what it was.
"Oh yes, oh please baby, please fuck me" She growled out through teeth clenched with anticipation. She leaned forward by bending her arms against the glass while simultaneously pushing her butt out towards me.
I didn't keep her waiting. I pushed forward, slowly and steadily until I was buried in her as deep as I could go and then I began that dance as old as time, slowly, teasingly pulling back and then thrusting forward faster, then pulling back slowly and thrusting again. Each time I did she ground out a noise that was half grunt and half moan. That noise alone was driving me insane but coupled with the small stud on the base of the phallus that was rubbing relentlessly against my own clit I was having a hard time keeping a steady rhythm, either with the strap on or with the fingers of my right hand which were still circling her clit.
"Oh fuck,.....Oh fuck,......harder baby.....more!"
I pushed the sensations I was feeling as far from my mind as they could go and tried to concentrate on what I was doing. Picking up the pace I was now just thrusting equally, in and out of her as fast as my hips would allow. My left hand was holding on to her hip and guiding her to ensure that I kept the angle just right to be maximizing my chances of hitting that Gspot.
My voice close to her right ear I panted out through my exertion saying "Oh yes, that's it, you are loving being on display, aren't you?.......Loving being fucked for all the world to see!" before I bit down on her shoulder.
She squealed and banged the palm of her right hand against the glass.
"Please, please,.......more"
I tried to speed up again and have no idea if I managed to, but my thrusts certainly became wilder and more frantic. My own orgasm was starting to build and I briefly worried that I may not be able to take her to the edge before I fell off it myself.
Thankfully, a ere 10 seconds latter she was screaming,
"yes,...... oh baby,.... fuck,........ fuck I'm gonna cum.....you are gonna make me cum....oh fuck....yeeessssssss!
Somewhere about halfway through her diatribe, my body tensed and I froze, strap on buried deep inside her as my whole body trembled and shook and I came feeling like I had washed over a waterfall in a barrel. She had collapsed forward so her face was turned sideways against the glass and I collapsed forward against her back. Both of us panting and desperately trying to catch our breath.
Eventually shrugged a shoulder letting me know she needed me to move and as soon as I backed away she turned and enveloped me in her arms.
"Now that was fucking delicious and the best birthday present you could have given me."
She took me by the hand and led me to the bed. Standing by the edge she helped me out of my clothes and the harness and we lay down together, limbs entwined, swapping small kisses between every sentence as we whispered sweet nothings and fell asleep.
