Derek, my mother’s new boyfriend, was a pervy old man. After Mum split with my dad, her financial situation became precarious. Dad was always the breadwinner of the household. Once he left, Mum was in dire straits. Problem was, she was a materialistic woman, always wanting something for nothing and expecting the best of everything. So she was determined to maintain her affluent lifestyle, even after Dad had gone.
It took a few months but she finally snagged a guy with lots of money. Problem was, Derek, her new boyfriend was a fat slob. But she took to him immediately, knowing her frivolous spending could resume as soon as she let the old perv in her knickers.
It was obvious Mum didn’t fancy him, just fucking him for his money. There was a big age gap between them too. Mum was thirty-eight and Derek was fifty-three. She was a hot MILF and Derek was a dirty old sex pest.
Their sexual preferences never really matched up either. Mum was always the prudish type, always dressing conservatively around the house. So she got quite the shock when Derek starting coming over to stay at our house. He was an absolute brute in the bedroom, a sex maniac, into all sorts of pervy things.
I would lie awake at night, giggling, listening to the noises coming from my mother's bedroom. Derek would give her a serious pounding. It would go on for hours and sounded like absolute carnage at times. Mother would be gasping and groaning, screeching and moaning. Derek would be grunting and snorting like a pig, growling and barking like a rabid dog. Then the bed would be squeaking loudly and the headboard slamming against the wall as the dumpy old man rutted her like a piece of meat.
Mother’s squeals and shrieks would come in perfect sync with the rhythmic slapping sounds as he fucked her hard and fast. Objects would get knocked over and smashed, clamouring loudly to the floor. He would slap her ass and demand she call him daddy.
Derek would shout things like, “Come on, girl, get my bollocks in your mouth and suck ‘em like gobstoppers,” and “Sit on me face so I can stick me tongue up your ass”.
I would lie there masturbating frantically, listening to the sounds emanating from my mother’s room. It was a massive turn on hearing Derek treat my mother in such a manner. It brought back memories of sex with my first boyfriend, a much older man called Paul, who took my virginity and treated me like a little fuck-slut. He used to call me dirty names and tie me to his bed and once even had a stranger come round to fuck me. He introduced me to bondage and all manner of sexual fetishes.
But Mum wasn’t as slutty as me. Besides that, Mum and Derek were worlds apart in their appearances. Mum was a real stunner with blonde hair and long, slender legs and big firm tits. Whereas Derek was a stout little man with a big beer belly and an unshaven and dishevelled appearance. He also had a balding head and a really hairy body.
By this time I was seventeen and a promiscuous girl who loved sex. I had already had a few sexual partners, all older men who had treated me like a little fucktoy, and I had enjoyed every minute of it. Recently, I had also found I had an insatiable desire for flashing my body to older men, especially the dirty old men in the local park. The thought of teasing Derek with my teen body appealed to me, so I decided to go through with it the first opportunity I got.
Mum went out shopping with her friends one day, leaving me alone in the house with Derek. It didn't take long for me to strip off everything but my pink cotton panties. Then I nonchalantly took a position on the floor in front of the TV, lying on my stomach with my head propped up on my hands.
"Don't you think you should be wearing something more than that?" Derek asked, his eyes roving over my taut teen body.
“Don’t be such a boring old fuddy-duddy," I sighed, my eyes on the TV, my bare feet waving in the air behind me.
Derek studied me as I watched TV, my cotton panties stretched tight over my round little buns. I listened to his breathing as it became laboured and heard his hand rustling around inside his underpants fiddling with his cock.
I watched his reflection in the TV screen and knew I was getting to him. Great! I thought.
Once again, I was experiencing my fantasy of exposing myself to someone and them reacting with sexual arousal. I got up from the position in front of the TV and turned it off. I felt like pulling my panties off right there but was a little afraid of getting caught by my mum if she returned home early.
Besides, I was getting a thrill from teasing the dirty old codger, so I decided to play the teasing game a little longer.
I took a deck of cards from the cupboard and asked Derek if he wanted to play. He said no, so I sat down in front of the glass coffee table and began to play solitaire. As Derek was sitting on the couch across from me, he could see down through the transparent glass. I had my bared legs and feet straight out in different directions. This caused the material of my panties to slide up my cunt crack, revealing the outline of my plump pussy mound and moist slit.
"Would you be more comfortable without those panties? They look kinda tight," he said, a nervous stammer in his voice.
"Yeah, they are getting kinda small for me. I’m going to go get some other ones." With that, I sprang up and dashed off to my room, coming back shortly with a half-dozen pair of assorted panties. "Which ones do you think would look good?" I asked, teasing the old perv.
At this point Derek had sweat trickling down his chubby cheeks, his stubbly face red and flustered. He was wheezing and sitting up in his chair, eyes fixated on my body and new panties.
"I dunno. I guess those," he replied, pointing to some low-cut, blue cotton bikini panties.
"Okay, I'll try 'em on," I said. But instead of changing in front of him, I went just around the corner. "No peeking," I said, as I slipped out of one pair and slowly pulled on the other. But he didn't have to peek. He could see my reflection in the glass door of the stereo rack across the room. I was turned slightly so that he had the perfect view of my naked profile.
In a moment, I bounced back around the corner, my blue panties tightly adorning my pert butt and tender pussy. The waistband was a full two inches below my navel, lower than the other ones were, showing much more of my flat tummy. Derek’s excitement continued to grow.
"Are these better?" I teased.
"Come here and let me see how they fit," Derek said, his eyes bulging.
Within seconds, I was right in front of him. Derek pulled at the waistband and leg bands as if to check the size. Then he let the fingers of one hand go beneath the leg band to find my wet cunt crack. He massaged my slippery little slot with his finger.
"What are you doing?" I asked, playing the innocent girl. But I just stood there and let him play with my pussy.
"Well, I wondered if there was enough room in these panties so that I could play with your cunt while you kept them on. But it looks like they're too tight. Fucking take them off, you little cock tease," he growled.
"Yeah, they are kinda tight," I said. Then, in a single, swift move, I put one hand on each side of the waistband and pulled them down to my ankles. “Get your tongue between my legs and lick me out, you dirty old fucker,” I demanded.
But the moment was ruined when Mum walked through the front door. I pulled my panties back up and make a dash for my bedroom. As I lay in bed playing with my pussy, I could hear Derek and my mum talking. After a few moments, my mum left the house again.
I had my blackout-blind pulled down over my window, so my room was shrouded in darkness when my bedroom door opened. At first, I couldn’t make out who it was. Although judging by the shortness of the figure and the rotund shape of the body, outlined with a beer belly and thinning palate, I knew it had to be Derek.
As he stepped into the room I switched on my bedside light. I was shocked at what I saw. It was Derek, naked except for his string vest and grubby white socks, his body matted with a thick fuzz of grey hair.
“Do you mind if I join you in bed, sweetie?” he asked kindly.
Having never been with a man this old and hairy before, I was a little scared at first. But the thought of this dirty old man in my bed appealed to me, made me moist between the legs.
