My wife kate has not long given birth to our baby girl and has decided to breast feed. She is 37 slight build with perfect tits and long nipples, her complexion is light and she has the tightest fanny you can imagine. Anyway the breast pump she was using broke down. It was a brand new one and very expensive so we needed it fixed. When phoned avent the breast pump company said they would send out the repar man. I was at work and my wife was on the shower when the doorbell rang on the day of repair. She threw on a dressing gown and answered the door. There was a grey haired gentleman in his seventies, called George Good morning I'm here to fix the breast pump! Oh my wife replied letting him in, I was expecting someone younger, no offence. That's ok I just do these repairs as a part time job in my retirement, I used to work for avent you see. Ok then my wife said that's the pump there carry on. She went to get dressed and let him carry on, baby was on an epic sleep so peace for a while. After a while George shouted through that it was fixed. Great Kate said I'm getting quite engorged. I hope you don't mind me doing this in front of you? She said. Carry on I'm used to seeing breast pumps in action. George said. Kate opened her feeding bra on both sides and let her engrossed tits spill out. George swallowed a bit at the sight of her young firm tits. She pressed it to her nipple and started the pump. It worked for a few seconds but then started making a grinding noise and Kate turned it off. Oh dear George said that sounds like the main gog is broken, the machine is knackered. But what can I do Kate cried look at my tits they are going to burst! Try hand expressing George said? I can't Kate said I don't have the technique! They are getting really sore! My husband was sucking the milk from them before you arrived to relive the pressure but he is not home for hours, I can't wait! Can you do it she asked, please help,me? Well ok I don't usually but since you desperate. George lay on her lap and Kate lowered her tit into his mouth, he latched on and suckered like a baby. Oh that's better keep sucking Kate sighed I relieve of the pressure. Can you do the other one too? With pleasure George mumbled, my wife's milk was dribbling down his chin, as he latched on to her other tit. You getting aroused Kate laughed as she looked at George's trousers growing a tent pole. Sorry George said its so erotic. Silly old man, Kate said how old are you? 78 he said but I still appreciate a beautiful woman like you. Tell you what Kate said, you helped me so I will help you, what position do you want me in? Missionary please! George couldn't believe his luck as Kate stripped and led him through to the bedroom. She lay there with her legs open and beckoned George. He struggled out his trousers and y fronts and climes onto our marital bed. A giant erection was waving out in front of him leaking pre cum. Better be quick Kate said, hubby is home soon. George rubbed his old penis against her fanny lips and Kate thought what a dirty girl she was and how she would tell her husband of this after. George pushed further inside Kate and moaned loudly he hadn't had a fanny this tight in years. Kate's tits were still leaking and George lapped this up too. Kate says you don't mind going bareback? I hate condoms, George gasped no problem, you don't mind me cumming inside I hate pulling out? Well I'm really fertile right now and we are trying for a baby so better not... That thought that he might get Kate pregnant pushed george over the edge, sorrrrrrryyyy he shouted! As he came deep in Kate's fertile pussy. Oh shit thought Kate as she felt the old mans cum flood into her womb I'm going to have to have a sperm race when hubby gets home! George lay inside Kate for a few minutes letting his cum seep in then withdrew. I have to go he said I will take the breast pump away for repair and repair it, I will return in a months time, hope you don't have your period when I return he laughed I would like to do that again! I won't have a period for 9 months now Kate laughed! I returned home from work to find Kate lying in bed ready for me in the missionary position, she hadn't moved! She told me this story and I almost came on the spot. I had to jump on and give her my seed too. Her fanny was very wet and loose and I loved the thought that she had just let a pensioner have a go at making her pregnant! I came hard in her and lay on top of her enjoying the wet feeling on another mans sperm leaking out of her fanny. My sprem was now mixed with an old mans, racing to catch Kate's fertile egg, fantastic... More to follow...
