It started when my mother suggested that as I obviously had nothing better to do on my day off work than laze around at home, why didn't I go and help her friend Della who had a problem with her car. My mother had a point. I'd earned a reputation of being able to fix cars and from Della's description it sounded like something I could tackle. I was still living at home at the age of twenty four, and this sounded like a welcome break from my boring routine.
I wouldn't have told my mother, but I had another reason for going to Della's. She was about my mother's age, mid forties with neat brunette hair and still quite attractive with a big boobed curvy figure and good legs. She also knew how to show that figure off in tight curve clinging clothes. I'd picked up from my mother that Della's husband had recently walked out for a younger woman. I'd also picked up that there might be more in the way Della looked at me than simply seeing a potential car mechanic. My masturbation fantasies usually involved girls, porn or real, who were my age. But in the past few months Della had become a regular performer in my wanking dreams.
I packed some tools and some old clothes I wore for dirty jobs and drove to Della's via a car spares shop. Della's car was parked on her drive. Della was in a top and tight jeans that showed off her big breasts and the curves of her legs and backside to perfection. I changed into my old clothes and got on with the job. As I worked I day dreamed about what was under Della's top and jeans and what I'd like to be doing with it.
It was a hot day and some of the parts I had to work on were stiff and hard to move. By the time I'd finished, mid afternoon, I was hot and sweaty, my arms were covered in black oily grime and I'd got grime on my face. When Della saw me she looked me up and down and suggested I take a shower before I changed back into my clean clothes.
So a few minutes later I was up in Della's bathroom. In it was a clothes drying rack, hanging on which were several pairs of Della's panties. Since I started masturbating in my teens I've had a thing about women's panties and frequently borrowed my mother's panties from the wash basket to play with. I liked to put them on and admire how sexy they looked and the way my erect cock bulged in them. I would masturbate over them or stroke my cock off through them while wearing them. Della's panties were far briefer than any of the typically white or pastel cotton knickers my mother wore. They were like the kind of sexy panties and tiny thongs my girl friends wore.
As I washed the grime off my hands, arms and face I felt my cock rising as I ran my eyes over Della's panty collection. I stripped naked for my shower, and I couldn't resist the lure of Della's panties. They were all sorts of colours, white, pink, red, blue and black, some were not much more than thongs or G-strings, and some were see through. With my hands now clean I took one from the rack: a black see through lace thong. I ran it through my fingers and stroked it over my by now hard up erect penis and imagined Della in it.
Just for fun I put it on. The thong would have looked brief enough on Della but on me it looked minute. My hard up cock pushed it out in a huge cone with the thin black lace taut over my big round knob. My penis was clearly visible through the lace and my pubic hair was poking out at the sides. I was admiring myself in the big wall length mirror, fingering my straining penis through the black lace when the bathroom door opened and in came Della - stark naked!
Della's naked body was every bit as good as I'd imagined in my masturbation fantasies. She had big heavy breasts with deep pink nipples and her vagina slit was neatly ringed with almost black cunt hair. She came straight to me and snuggled herself against me so her big soft breasts were gently pressed against my arm and her bare thighs straddled mine so her cunt was agains my thigh. She reached down one hand to finger my balls and run her fingers up and down the bulging ridge of my erect cock through the lace of her thong and caressed my bum with her other hand.
"I left my knickers out for you," Della said. "Do you like them?"
As Della pressed herself against me my one hand almost involuntarily went round her waist, slid down her back and over her hips to fondle her well rounded soft smooth bottom, the tops of her thighs and her lightly furred cunt. My other hand went straight to her big soft breasts. Della pulled her thong down round my thighs below my balls. My penis sprang out and in the big wall mirror in front of us I watched it bounce stiffly. My erect cock's not much more than six inches long but sticking up hard it looked massive.
Della's fingers were instantly on my balls tickling them and ruffling my pubic hair, and lightly caressing and stroking my penis shaft and head. I let Della's thong fall round my feet and kicked it aside. I spread my legs for Della's exploring fingers and involuntarily shoved my hips forward as my penis tingled with arousal and the beginnings of the cum Della's fingers were taking me to.
"Your mother told me you masturbate over her knickers," Della said. "Would you like me to wank you over mine?"
I stood there stunned with the triple whammy that my mother knew I had a fetish about her knickers, that she'd told Della I wanked over them, and Della's offer of a hand job! Without waiting for my reply Della continued.
"She says you lube your cock with this when you masturbate."
She detached herself from me for just long enough to reach for a bottle of body oil on the bathroom shelf. It was the same brand as my mother's bottle in our bathroom. I'd discovered early in my masturbation career that with my hand well oiled my fist round my shaft felt just like a tight juicy vagina. My mother must have noticed the level in her bottle slowly going down. Della snuggled her naked body against me again and smeared the oil onto my straining penis shaft with her fingers. The feel of her warm oiled hand gently stroking my shaft and knob as she spread the lube over my shaft and penis head, with her fingers lightly tickling my balls was exquisite.
She ran her finger up and down the underside of my penis, with the bend of her knuckle catching that so sensitive spot where my shaft meets my knob. My cock felt taut enough to snap and ready to explode, with the veins standing up along my shaft and my knob a deep reddish purple. I was almost on the brink already. I groaned with the sexual pleasure.
"Go on! Wet my knickers!" Della said in a soft voice, but with an edge of excitement.
Della's black lace thong was at my feet but the rack was close to my hand so I took a pair of pale pink satin panties from it. I stretched them and brushed the taut satin over my shaft and across my penis head the way I'd done so many times with my mother's panties. My penis left a wet patch of pre cum on the pink satin. I could tell Della was getting more and more excited as she watched me excite my cock with her panties.
Della wrapped her hand round my shaft with her thumb and finger in a ring just below the base ridge of my cock head. I spread my legs wide, shoved my hips forward and braced myself. Then Della hand jobbed me. She stroked and tugged my foreskin with her well oiled hand tight round my shaft sliding methodically and rhythmically up and down full length. With one hand I held Della's panties in front of me with my penis head against the satin, stroking the smooth cloth across my sensitive, lust swollen penis head. I couldn't keep my other hand off her bottom and thighs. As she pleasured my cock with one hand Della caressed and tickled my bum with her other hand, reaching right under me to tickle my arse and balls from underneath.
All the masturbation fantasies I'd had about sex with Della flooded through my mind. This time her naked body was against mine for real and instead of just dreaming of her nude. In the wall mirror I ogled her body and watched her big breasts bobbing with the rhythm of her hand on my penis.
