My wife, who I shall refer to as Tracey, and I have been married for over forty years, yet still have a good sex life. It helps to be well-hung and in good shape and up to trying out new ideas and themes.

Just recently my wife came home from work and said, "In our tea break, all the girls have been talking about blowjobs."

I thought it was only guys who talked about that subject so of course my ears sprang up and I wanted to hear what was said. My wife works with six other women and one male in a local pharmacy, the women's ages vary from mid-twenties to late fifties. It would appear that the male, who is the pharmacist, was not privy to the conversation about blowjobs.

It turned out that during this strange conversation - and how they got onto the subject I still haven't found out - Liz, a slightly chunky lady in her late twenties with enormous boobs, informed the group that she had never given any boyfriend's past or present a blowjob.

Liz admitted to watching videos on her phone and her laptop when alone and wanted to pleasure her man but for fear of doing it wrong had never tried.

The other women all admitted they loved to pleasure their man orally, some swallowing and some not but in the main loved the experience.

This conversation went on for days, with the girls talking about techniques and where and when they had completed the act. A couple of the girls admitted they had even done it with a stranger at a party and during a one-night stand even though they were all happily married.

Tracey said over dinner that night, "I have an idea. Let me know your thoughts as you might like what I am about to say."

I was intrigued and my cock was swelling in my boxers as I could see myself getting a blowjob after dinner. That was not what I was being offered, as I soon found out, but the idea Tracey had sounded great.

Tracey said, "What if I said to Liz she could come round here and you would let her practice giving a blowjob on your big cock?"

I said, "In principle, it sounds great, but you have to be sure you are ok with it, and why would a young woman like Liz want to give an old man like me a blowjob?"

Tracey said, "All good questions, I am up for it I find it a huge turn-on and am quite excited about the thought."

I said, "You know I love having my cock sucked, so having someone different working on it sounds like a weekend pass but you need to be sure."

Tracey said, "I am I am, I will put it to Liz. I will take some pictures of your cock limp and hard and show her so she can see what she has to work with. Her boyfriend only has a small cock or so she says, so she might get a bit excited at the sight of yours."

After dinner, Tracey took a few pictures of my cock, she shaved me so it would look even bigger then she gave me a masterful blowjob and swallowed every last drop.

I didn't hear anything for a few days then out of the blue Tracey said, "Liz wants to meet you properly away from my workplace and talk to you about our offer."

I said, "Did you show her the cock pictures on your phone?"

Tracey said, "Yes I did and she loved them, she went weak at the knees and was licking her lips at the prospect, and cannot wait to meet him in the flesh." She also said, "I have never seen a circumcised cock before, or one so big and thick." That made me smile.

We arranged for Liz to come over for dinner after work one evening, and we chatted over a few glasses of wine about what and how we would play out this strange situation. It was agreed that Tracey would have to be present and that she would take the lead and teach Liz the different techniques and strategies involved in oral sex.

This was the first time I had seen Liz outside her place of work, she was much prettier than I remembered and not as chunky either. Liz was dressed casually in a thigh-length skirt and tight-fitting blouse that showed off her huge boobs. She wore nice heels that accentuated her really good strong legs and had a small amount of make-up on, she was though very nervous.

We all agreed that as Liz was not seeing her boyfriend that Sunday afternoon it would be the perfect time to have our first lesson. To be honest I didn't even consider there would be more than one lesson, but I must admit I was excited at the prospect of fresh lips around my cock. Lips that my wife consented to was a bonus and a rarity.

Sunday arrived, I was very nervous at the prospect of getting a blowjob from a young woman who had never had a cock in her mouth before, one who I have to admit I quite fancied. I was hoping that Liz would be up for it, and ready to give it a good go. On top of that get naked, so I could see those massive boobs.

Liz arrived, and before we got down to any business we shared a couple of bottles of wine to help shed her nerves and loosen her inhibitions.

I left the ladies to talk tactics and retired to the master bedroom, I changed into a pair of loose-fitting boxer shorts, ones that would be easy to remove, and a t-shirt.

Minutes later I was joined by the ladies who had both stripped down to just their bras and panties. Liz looked fabulous she was fit, and although a slightly bigger frame than Tracey was not carrying any fat. The sight of her made my cock swell in my boxers.

Tracey said, "It is clear you like what you see from the reaction of your cock."

I said, "Well yes, you two look fantastic."

They both replied, "Thank you."

Liz looked really nervous and very timid, I did notice that she could not take her eyes off the tent slowly appearing in my boxer shorts.

Tracey approached me where I was sitting on the edge of our kingsized bed and made me remove my T-shirt, I discarded this then she knelt in front of me and yanked down my boxers leaving me naked.

I went to cover my cock with my hands but was told not to by Tracey, "We need to see him and start the lesson so just relax."

I was positioned lying in the middle of the bed and the ladies climbed on either side of me, I just closed my eyes and let what would be take its course.

I felt a hand wrap around my cock, I knew it was Tracey, Tracey then started to give Liz encouragement and instructions and invited her to join her and take my cock in her hand. I felt another hand wrap around my cock and sighed at the prospect of what was about to happen. I was in dreamland.

As I lay there with two beautiful ladies tending my every need I said, "I am naked it is only fair that you should be as well." It was said more in hope than in expectation.

Tracey said, "I am game how do you feel." speaking to Liz, who just nodded and proceeded to remove her bra and then her tiny panties, Tracey followed suit.

With all of us naked I looked up and marveled at the size, shape, and firmness of Liz's massive boobs. Her saucer-like dark areola and nipples are almost an inch long and so thick and erect.

Instinctively I reached and took one in my hand and gently massaged it, I was expecting an adverse reaction but it was the opposite Liz moaned and pushed her breast toward me to get more attention.

Tracey smiled at me, gave me a thumbs up, and said, "I think we are ready to start the lesson."

Tracey explained to Liz exactly what she was about to do and asked her to watch closely. She would be taking her turn very shortly and to do exactly as she was doing.

Liz let go of my cock and I removed my hand from her boob so she could concentrate. Tracey then started to lick along the length of my cock from my balls to the tip kissing and biting it along its full length. She cradled my balls in her hand and caressed them, but still did not take my cock in her mouth.

Tracey did this for a few minutes then stopped, she looked up at Liz and said, "It's your turn just do as I did. Take your time and only do what you feel is right, no pressure."

Liz looked nervous, so I closed my eyes as I didn't want to put her under any pressure and certainly didn't want to force her to do anything she felt awkward doing.

I felt her wrap one hand around my length and another cup around my big-shaven balls. I felt her reposition herself on the bed and one of her huge breasts touched my leg, then for the first time, Liz licked my cock.

The feel was sensational, this lady had never given a blowjob before, and she licked me like an expert. I twitched, my cock twitched, and she stopped and said, "Am I doing something wrong?"

I said, "No, you are not, It was perfect just carry on doing that and you will get no complaints from me."

Liz smiled back at me, her massive boobs wobbled as she let out a little chuckle.

Liz once again took my cock in her hand and my balls in the other. She then lowered her head over my cock and resumed licking me along its length, this time kissing my balls when she arrived at the base. She was good.

This went on for just a few minutes, then Tracey decided it was time to move on. They changed positions Tracey explained what the next step was to be. Was I finally going to feel Liz's lips around my length, that is if she wanted to go to the next level?

I waited and felt Tracey lower her lips over the end of my cock and start to bob up and down, stopping occasionally to swirl her lips around the end and then resume bobbing up and down. Wow! Would Liz be brave enough to follow, I would soon find out. How adventurous would she be, would she have a good technique? She was being taught by the master so I would expect her to be the perfect student.

Tracey stopped and looked at Liz and said, "How do you feel are you ready to give it a go?"

Liz nodded and positioned herself between my legs, looked at me with her big brown eyes, and said, "Are you ready? Please let me know if I hurt you or did something wrong,"

I smiled back and nodded my approval, still focusing on her huge perfect boobs.

Liz leaned forward her huge breasts came into contact with my legs and felt so good, soft yet firm. Then the moment I had waited for her lips came into contact with the tip of my cock. She licked around the tip, swirling her tongue around and around pushing it into my pee hole, I was ready to shoot my load already but knew I had a long way to go.

Then she took my cock in her mouth, inch by inch until she hit her gag reflex and coughed and stopped momentarily. Then she started again this time not taking so much in her mouth, and then there she was bobbing up and down on my cock. Slowly at first, then stopping to lick and swirl her tongue around the end as she was taught. Then she was off again taking more and more of me in her mouth and and sliding her perfect lips up and down my length.

I placed my hand on the back of her head, firstly to encourage her to take more and to help regulate her speed. She looked up at me and winked then continued. She was good, very good.

After a few minutes, Tracey asked Liz to stop, she didn't straightaway but after a few more seconds she came up for air.

Liz looked at me and asked, "How did I do."

"Wonderful," I replied. "A few minutes more and I would have filled your mouth with my load."

Liz said, "Really? Can I continue then?"

I was seriously thinking that it was impossible that this lady had never given a blowjob before, she was amazing in every way.

I said, "Are you sure you have never done that before?"

Liz replied, "No never, I have had cocks between my tits but never in my mouth."

I wanted to say yes please, as I was so close and I wanted to experience putting my cock between her tits, but Tracey said, "We have all afternoon there is no rush to finish him off so soon."

Liz looked disappointed, and so was I, but I was in for a great afternoon of experimentation.

Liz said, "You seem to have mastered the art of oral, and of course, I will let you finish him off but all in good time. Do you want to ride that beast of a cock?"

Liz looked at Tracey then down at me and said, "I would love to, I have never had a cock that big inside me or a circumcised one. So if that is an option I would love to."

I said, "I am game as long as Tracey is okay with that." Still lying on the bed with an erection as big as the Eifel tower.

Tracey smiled, "We have come this far, she might as well take advantage of the chance."

I said, "Are there any more of your co-workers who want to practice giving blowjobs?" For that comment, Tracey slapped me hard across my thigh and said, "NO." But with a cheeky grin on her face.

I now had the license to get some action, I slipped my hand between Liz's legs and with no surprise found she was so wet and ready. I inserted two fingers into her dripping pussy and got the response I wanted, she moaned and shuddered and orgasmed almost straight away.

I pulled my hand away and motioned for Liz to ride me, I needed her to climb onto my cock and lower her pussy down on my length.

After a bit of shuffling around and awkwardness, Liz was sitting astride me. She positioned herself above my big fat hard cock, so I moved him up to the entrance of her pussy.

I looked up at Liz and said, "You are under no pressure to do this, only do what you feel comfortable doing."

Liz smiled and slowly lowered herself onto my cock, it was tight at first but slowly her pussy swallowed my length inch by inch. Her pussy had swallowed at least half of my nine-inch length when she stopped, just for the briefest moment then she started to ride me.

Her enormous boobs were flailing everywhere and she was in danger of blackening her pretty eyes, that is where I stepped in and took one in each hand to save her from injury.

I held onto her huge perfect firm boobs as she rode me like a devil possessed. I looked to my right and smiling back at me was Tracey, She said, "She is good, isn't she? Just let us know when you are going to come."

I saw Liz's face change to one of extreme pleasure as she had her first orgasm, this was massive and almost flooded the bed with the amount of juices she shot out of her pussy.

She had another two of these but not quite as wet before I had the urge to shoot my load. I looked at Liz and said, " Do you want to suck me off or shoot my load inside you?"

Liz said nothing but continued to ride me harder and faster which clearly meant she wanted me to fill her up.

Tracey said, "Go on then fill her up."

I didn't need a second invitation and sprayed the inside of her pussy with shot after shot of my hot load that brought her to her fourth orgasm, after which she collapsed on top of me squashing her boobs into my chest, and instinctively kissed me hard on the lips.

I was in no position to stop her and responded until that is she realized what she had just done. Liz stopped kissing me and sat up still impaled on my cock.

Liz said, "I am so sorry I just got carried away with the moment, it just felt so natural."

Tracey said, "It is only natural, and no one minds as long as you get what you need from this lesson."

Liz finally climbed off my still erect cock, she looked at it and said, "How is it possible you are still so hard, my boyfriend's cock just shrivels up once he has come."

Tracey and I just chuckled, this was just normal to us but clearly not to everyone.

Tracey said, "You can suck him again if you wish to practice some more, or you can come around again another day if you still need help."

Liz said, "I don't need any more help I think I have the tools I need, but I would love to suck him again. I would love to come back and have another afternoon of fun if that is ok?"

Tracey just smiled, nodded, and motioned for Liz to carry on.

Liz wiped our juices from my cock and positioned herself between my legs ready to give me another blowjob.

I stopped her and suggested we get into a sixty-nine position so we could both benefit from the experience, Tracey nodded her agreement and permission.

Liz was nervous and slightly awkward but agreed it was the right thing to do so she could repeat the position with her boyfriend.

We moved into position, and Liz lowered her pussy onto my face and her mouth above my cock which was difficult due to the size of her huge boobs which were squashed between us in my tummy.

It was decided we try changing positions and she lay on the bed and I straddled her, this was much more comfortable and allowed me to control how much of my cock she got to swallow.

Within minutes Liz shuddered to another massive orgasm and sprayed my face and mouth with her sweet juices. This happened twice more before I announced I was about to come, Liz increased her tempo on my cock and I helped by bucking my hips and pushing more and more of my cock into her mouth.

I knew she wanted to try swallowing semen so just let it go, I poured shot after shot into her open mouth. She spluttered and struggled to swallow the huge load though. I knelt up beside her face, then moved my cock towards her mouth and wanked myself over her face and into her open mouth.

She swallowed this with ease and even took my cock in her mouth to lick and suck off the residue.

I said, "Where did you learn that?"

"The internet," she responded, "I loved that, can we please do it again and real soon?" she said.

Tracey answered before me and said, "Yes please, I think I came as many times as you just watching," and laughed.

We all chuckled and agreed it was a great afternoon.

We arranged to have a further meeting, and then after cleaning up and drinking more wine, Liz left.

Once alone Tracey and I headed to the bedroom and spent the rest of the day indulging in each other's bodies.

We hope to see Liz in a couple of weeks, hopefully, she will have put her training to good use. She will report back and learn a bit more.
