Helping my mom's friend

After fucking and losing my virginity to my aunt Jackie and getting caught by my mom (her sister) I began to make up for lost time. I fucked every girl 19 and older I could get my dick into, I had to swear to my mom that I would use "protection" wouldn't want to knock anyone up and have father's coming after me with shotguns now, would we?
Our next-door neighbor and one of my mom's friends Lisa was a 50-year-old divorcee, she was about 5'7" 130 pounds with long black hair and a 37-26-36 figure that would make traffic come to a stop when she went jogging, no lie I actually saw a couple of car accidents because guys were looking at her. Anyway, she was always asking me to come over and do chores for her yardwork and such. Frequently she would sunbath in her Bikini while I was working in the yard, I would run home and jerk off never did I imagine I would get to actually fuck her! She did have gentlemen "callers" over but very few lasted more than a single night.
One day she was called and asked me to come over and install a ceiling fan complete with lights, sure no problem so I grabbed my tools and headed over. Knocked on the door Lisa opened it wearing a T-shirt and shorts as it was a hot day. She showed me where to install the fan and I got to work, she let me use her ladder so I could get into the attic to drill the holes and install the wiring. It was over 100 that day and needless to say her attic was stifling so I was pouring sweat by the time I got done. Oh, good you're done! she saw me sweating. Oh, why don't you go jump in the pool and cool off while I get a soda for you! I went outside took off my shirt and dove in swam for a few minutes.
Lisa came out, here's your soda! I waded to the steps and got out she handed me the soda looked down and said OH MY! I looked down and realized that I was wearing a pair of white shorts that when wet can be very transparent since I wasn't wearing underwear. My cock began to grow under her gaze WOW you are hung! she put the soda down walked up to me placed her hand on the shaft and began rubbing it gently as she did this we began to kiss passionately our lips parted and tongues intertwined exploring each other's mouth, she moaned softly as I rubbed her tits through her shirt bringing her nipples erect.
She slid her hands along my waistband and pushed my shorts down allowing my cock to spring free, I moaned as she began stroking it. I pulled off her shirt threw it on the ground, reached around unclasped her bra letting it fall on the ground I began rubbing my hands all over them. They were so firm and soft her nipples were erect begging to be sucked and licked which I promptly did. She moaned that's it suck it OOHH just like that now the other one OOHHH YESS baby!! I tried to slide my hand down the front of her shorts, but her belt kept getting in the way finally I stopped sucking her tits reached down undid the belt and unsnapped her shorts sliding over her shapely ass and down her legs. She kicked them off as I picked her up carried her to a lounge set her down on it and buried my face in her pussy. I used all the moves my aunt taught me running my tongue up and down her vagina slowly at first then quicker as I gradually zeroed on her clit. Judging by her moans and gasps and the way she moved her hips she was close to orgasm. I flicked my tongue over her clit and then took it between my lips and sucked on it.
That pushed her over the edge, I'M CUMMINNNNGGGG she cried out as her powerful orgasm roared through her body, after several minutes she lay there gasping in the wake of her orgasm. I kissed my way up her body stopping to suck on her nipples before moving up to her lips. We kissed as I positioned myself at her entrance to mount her, As I pushed the head into her, we both moaned as my cock sank all the way into her pussy. How big are you? she moaned 9 inches She replied God, I believe it! I began to thrust in and out marveling how her vaginal muscles gripped and massaged my cock. She put her feet on the ground so she could thrust her hips up as I thrust down allowing me to bottom out in her pussy. FUCK ME WITH YOUR BIG COCK, FUCK ME WITH THAT BIG COCK BABY she cried out. I began thrusting harder THAT'S IT FUCK ME HARD WITH YOUR BIG DICK MAKE ME CUM WITH THAT BIG DICK OH YESSS YOU HAVE SUCH A BIG DICK FU FU FUCK ME HARD I thrust even harder and faster as she pistoned her hips up our flesh slapping together YOUR DICK FEELS SO GOOD INSIDE FUCK ME FUCK ME WITH YOUR BIG DICK OOHHH I'M CUMMING FUCK ME FFFFUCCKKK MEEE! A second more powerful orgasm roared thru her body Her vaginal muscles clamped around my cock.
I couldn't hold it any longer and I grunted as I pumped my sperm into her. Spurt after spurt was pumped into her spasming cunt. As I continued pumping into her, she cooed OH BABY SOMEBODY'S FILLING ME UP WITH HIS CUM! Finally, after a final spurt I collapsed on top of her.
We lay like that catching our breaths and I realized I used no protection! Shit I should have pulled out! why? Lisa asked I wasn't wearing a condom what if I get you pregnant? Lisa smiled don't worry I'm on the pill and I am starting menopause so you can't knock me up. That's great because my mom would kill me if you had my baby. Lisa laughed that would be such a waste of a great cock! suddenly she squeezed her vaginal muscles around my cock causing it to begin to get hard inside her. You like that? she squeezed again and again oh yeah, I can feel you getting hard inside of me, she looked up do you want to fuck some more? Oh yeah, I replied as I began thrusting. We spent the rest of the afternoon fucking in the backyard, we did it in every position: me on top, her on top, doggie style, on our sides, she even gave me a blowjob and let me cum on her tits followed by more fucking. Towards the end I'm sure I was not pumping any sperm into her she just used my cock to get herself off. Finally we got dressed and I staggered home. My mom asked what took you so long? Then she looked at my face Oh jeez did you have sex with her? I nodded and as I walked down the hall to my room she said to my back: You and your hormones are going to be the death of me.
