Mark's solemn nod while he lowered his lips to my left breast again, reassured me while at the same time his lips and tongue sent tingles up and down my spine. I could feel the warm pleasure building in my chest, and barely noticed when he slipped his finger inside me. He pumped slowly, letting my body adjust to his graceful digit. On my end, it was absolute heaven. Mark's lips were sucking and pleasuring my breasts while his legs supported me, and at the same time let me rub myself against the strong muscles of his thigh. Then, behind, I was wonderfully impaled, filled and taken by the man I loved.
I don't remember how long Mark kept up his digital stretching, but the next thing I was aware of was the tight coil of tension building in my stomach, one of the precursors of an orgasm that I knew meant I was going to lose it soon. Mark heard the change in my gasps and moans, and shifted his legs slightly, letting my clit rub directly against his thigh. I came quickly after that, moaning and calling his name softly while he supported me with his free hand.
When my climax had passed, he kissed my lips again. "Do you want me to stop?" he asked me, concern in his voice. "You don't have to do anything you don't want to."
"I know that," I told him, stroking his face and looking him in the eye. "It's why I know you're the only person I trust with this."
I reached down under the water and wrapped my hand around his cock, which was still rock hard and thick. There was no way I was ready at that point. "What do we need to do?"
"Bend over the edge of the tub," Mark said, slipping out of the water and going to the medicine cabinet. Inside we had a few of the various toys we'd collected, but he came back with a large tube of lubricant. "This might feel cold after the bath water, I'm sorry about that."
"Well then," I teased, wiggling my bent over backside at him. "I guess you'll need to warm it up then."
Mark coated two of his fingers in the shiny, clear gel before capping it and setting the tube in the overflow area of the tub. It made sense, it was almost as warm as the bath water. "Okay, now look at the wall, and push back, see yourself opening up," he said.
I did as he asked, in my mind's eye imagining my ass opening up to allow him in. There was a moment of tightness, but suddenly both of his fingers were inside me, massaging my inner walls and filling me with delicious fullness. At the same time, his other hand continued to rub and massage my back, relaxing me and letting me feel calm and at peace.
Just when I thought I could actually feel my body start to rise again towards another climax, Mark pulled his fingers out. Getting out of the bath, he lay down on the thick faux fur rug that we use for catching drops and smeared another glistening dollop of lubricant on his cock, until it was shiny and ready. "You control your depth," he said simply.
I nodded and got out, making sure my feet were dry before squatting over top of him. I could feel my ass still wet and ready for him, and I took him in my hand, looking into his eyes. "I love you, Mark."
"I love you too, Sophie," he said, and I lowered myself down. It's one of the benefits of having a super-fit hitman as your fiancee, you get lots of exercise. My legs, which couldn't have supported the squatting position for very long before, gave me plenty of control as I felt the blunt spongy head of his cock push against my ass. It was bigger than his fingers, but it wasn’t too much for me, and except for a momentary twinge of pain, I guided myself down onto his cock in a smooth, amazingly sexy descent.
"Oh fuck," I groaned as my hips settled against Mark. I'd read about anal sex before. Hell, it's not exactly a subject that you go into blind nowadays. I'd read both the good and the bad, and all I can say is, the good paled in comparison to how I actually felt. It wasn't just the fact that I had Mark inside me in a way no man had ever been before. It was the look in his eyes, and the calm assurance in his face as he held my hips in his hands. There were no words to describe it.
"I'll go slow," Mark promised me as he lifted my hips up slightly before holding me there. He began to thrust, slowly at first, letting me feel the taboo pleasure make its way through my body as our eyes stayed gazing into each other. I swore I could see into Mark's soul, which was just as beautiful as it was tortured. Still, his love burned bright for me, and as his hips increased in pace, I could feel that burning start up again deep in my belly.
I pushed back, stroking my ass up and down Mark's cock as my own desires took over. As I did, I marveled at how perfect our position was. My breasts dragged against the strong muscles of his chest, while at the bottom of each filling thrust my clit ground against the flat muscle below his belly button. I was filled, I was taken, and I was safe all at the same time.
The only thing that our position wouldn't let us do was last. It just felt too damn good. My hips sped up, to be met by Mark's thrusts, and soon both of us were trembling on the edge of another orgasm. I looked up into Mark's eyes and nodded, pushing myself back and squeezing down. I saw his eyes roll up in his head and I knew he was ready. I was quick to follow, reducing me to a trembling, teary mass on the rug. Mark's arms held me tight through my convulsions, his body never pushing me away or pulling me too tightly against him. Finally, my convulsions passed, and we lay against each other until I started to shiver. "What's wrong?" Mark asked.
"I'm cold," I told him. "Let's get back in the bath."
