Missionary position

We both lay there for a moment, getting our breath back. I still had a raging erection and Kirsty's nipples were still hard and standing proud of her voluptuous breasts.

"Well, that was good," I finally said to her, turning to her with a broad grin on my face. I felt another fart coming and let rip with abandon.

"Mmmmm, come here you dirty boy," replied Kirsty, opening her arms and legs wide and inviting me to mount her. I didn't need any further persuading. I rolled into a kneeling position between her legs, my giant, throbbing cock standing proud over her stomach, the end of it almost meeting those huge tits. I looked down at my wife, a huge smile on her face, her bosom heaving, her pussy still wet.

"Come on, Billy, I need you inside me," she begged. She never normally talked at all dirty, never swore, and this rare bit of sex talk from her was turning me on. I decided to see if I could get more out of her. Leaning down, I started sucking on a nipple. She moaned in pleasure and used a hand to hold me against her giant tit as I licked around her pert nipple. I felt her other hand reaching my cock and, feeling its size and hardness, she moaned again.

"I need you... I need your..." she started. I pulled away from her tit and looked up at her face.

"Yes?" I enquired, grinning cheekily. "What exactly do you want me to do?"

"I want you to..." she paused again, this time to let rip with an enormous fart that I felt vibrating through the springs of the mattress. "Give me your..."

"Come on, babe, say it," I teased. "Describe it to me."

With that, her inhibitions were gone. "I want you to put that massive, throbbing cock of yours..." she paused, a sheepish grin crossing her face at the rudeness of her own words, "inside my warm, wet, pussy."

"Oh, ok," I replied, and pulled back to place the head of my dick against the lips of her cunt, then ease it inside her. I sighed at the sensation of her tight snatch around my cock again, and she gasped in delight as she felt me fill her pussy again. She started to thrust but I resisted, asking, "Anything else you would like me to do, dear?"

"Uh... I... uh... I want you to..."

"Come on Kirsty, talk dirty to me. This is a dirty weekend after all."

"Ok, big boy," she said with a smile on her face. "Screw me. F- fuck me." I began to thrust. "Fuck me, fuck me, fuck fuck fuck faaaa yes YES YES!!!" By this time we were thrusting in unison, my chest upon her giant boobs, her hands on my arse trying to pull me ever further into her. Our mouths locked in embrace as we shagged for all we were worth. I had one hand under her arse and the other playing with one of those massive tits. As we neared our climax our mouths separated so that we could breathe, and both of us were grunting in pleasure as my giant dick pummelled in and out of her fuck-hole.

"Yes, yes," Kirsty gasped. "Now your turn. Talk dirty to me. Ah! Fuck! Tell me about my boobs!"

"Uh," I grunted, "yes! They're huge." Turns out I wasn't much good at sex talk either. "The biggest fucking pair of tits I've ever seen!" That was more like it. She raised an eyebrow.

"You've seen others?" she asked with a cheeky look on her face as we continued fucking.

"Only pictures," I replied. I suspected she knew I watched quite a bit of porn, especially during the autumn and winter when our sex lives were almost non existent. "But yours are the fucking best, so I'm going to fuck your tight little pussy with my mighty big cock until I can fuck you no more!" We had never used the "f" word in front of one another before and the thrill of talking this dirty to one another during sex was a real turn-on for us both.

But shortly we reached the stage where we could no longer form words - pure animal instinct kept us gyrating our hips, grunting and moaning until finally, we came together, both our hands gripping one another's tight buttocks as my dick shot load after load of cum deep into Kirsty's greedy cunt. Our thrusting slowed, then stopped, and I lay exhausted on top of her, those magnificent breasts still full and firm beneath me.
