[MF] My introduction to sloppy seconds was when my flat mate left his girlfriend unsatisfied.

I [M21 at the time] got in late and the other side of my flat mates shut bedroom door was the obvious groaning associated with lady and gentleman games. I went to my room and stripped off, grabbed my dressing gown and settled on the sofa with some late-night telly. This is a quite a few years ago and late on a Friday in the UK, Channel 4 would show a crap foreign film which people only watched because it had a red triangle in the corner. This meant there would be nudity and hopefully sex.

The story was normally shit so I would play some music and just watch it with the sound down slowly stroking my cock.

A good half an hour later flat mates bedroom door burst open and in strode the girlfriend, naked. I didn't know her that well. They hade been together for a few months but when she was round she barely left his bedroom. I certainly didn't know her enough to expect her to be in the same room as me naked.

She had a hefty rack of tits that sagged down to a podgy belly and wide bubbly hips and arse. Jet black hair hang messily over her shoulders. Her pretty face was smudged with dark makeup.

"Oh sorry," she said when she saw me," I didn't know you were in"

She appeared to be in a bad mood. She made no attempt to cover herself. She had caught me off guard too and my gown was open with my hard cock standing up in my lap.

"That bastard has shot his load and passed out" she told me as she crashed about in the kitchen area for a drink or water.

"And I'm left unfinished again." She exclaimed.

I covered up my erection. By the time she had drunk some water she had calmed down a bit.

She set the glass down and looked across to me. "But you looked like you're horny and my pussy is hungry"

She looked over to the open bedroom door and then back to me and then started to head towards me.

"Would you like to satisfy me?" she asked as she got closer.

Her hard nipples were staring at me, now only a couple of feet away. My cock throbbed as I looked her up and down more closely. Brown wispy pubic hair spread across her mound and onto the tops of her thighs. A light pink hood of her clit popped through the patchy curly hair.

I wouldn't normally make a move on a buddies girl but it was on a plate in front of me asking for me to please her and it might even do him a favour if she went back to his room satisfied.

She answered for me by pulling open my gown and straddling my lap on the sofa and sitting down on me with my cock just in front of her. She reached out to the top of the back of the sofa and lifted herself up onto her knees, pivoting forward so her breasts pushed into my face, smothering me. She lowered herself onto my cock and her pussy swallowed it in. It was hot and sloppy wet. She sat right down engulfing the entire shaft. Her juices and his cum dribbled out of her and into my lap and down onto my balls. She lent back and supported herself with her hands on my knees and started grinding on me.

I lent forward and lapped at her hard nipples wobbling about in front of me. I licked and suckled on them.

"Harder" she called as she gyrated on me.

I nibbled and sucked them as hard as I dared.

"Bite me." she demanded.

I grabbed her left nipple between my teeth and applied pressure.

"More" she exclaimed

I obeyed and applied more pressure and pushed my lips onto her bosom and sucked as hard as I could. She was now fucking me hard, rocking back and forth and up and down. Her wet pussy squelched and quiffed as she pumped on my cock.

She was fucking me so madly there was a risk I would fall out of her. She felt so wet and loose on me I was surprised she could feel me inside her but she was getting off on it and reached around my head and squashed me into her chest. Her nipple was still clenched hard in my teeth as her chest smothered me making it hard to breath. She let out a great groan and quivered and her knees clamped onto my hips. She quivered again before relaxing her grip on me and settled back down onto me, my shaft still fully inside her.

I released her tit from my mouth. Small purple spots had formed on her areola.

She held onto my shoulders and started to slowly ride me up and down again.

"You can cum now" she told me.

"Fuck my pussy, fill me up. You deserve this. My pussy wants to thank you"

She talked dirty as she slowly slid herself along my cock. Her pussy felt so warm on me and my lap and balls were soaked.

"Do you like using his cum as lube to fuck me?"

I did find it hot and I was fit to burst.

"I'm gonna cum" I told her, expected her to get off.

Instead she sat right down on me and I could feel her clench her pussy around my cock.

"Cum in me." She told me and I felt my cock erupt inside her.

She lent forward again smothering my face with her tits as I pumped the last of my cum into her and we sat like that for a bit.

She eventually clambered off me. Her pussy had big globules of cum hanging from her lips and hair and some was running down her leg.

She went over to the kitchen and used the tea towel to wipe herself. (classy).

We thanked each other and she returned to my flatmates room and shut the door.

I had sex with her a few more times before they broke up. They would have sex until he passed out and she would either join me on the sofa or slip into bed with me so she could finish off and would reward me with some extraordinary pussy and oral talents. I even gave her oral, lapping at her gaping pussy filled with my flat mates cum and sometimes both of our cum.

Sloppy seconds has been a guilty pleasure kink ever since.
