Years ago a friend of my wife's was over at our house. She's a BBW with 36DD tits. We were all drinking outside on a hot summer night after swimming. I was still in my swim trunks and it was starting to get dark out. She had flirted with me for years and I had always passed it off as nothing. Well I was feeling a bit frisky and bold that night. My wife said she was going inside to change and get some food. I knew there was a short window. Once I knew she was inside the house, I whispered to her friend to look over at me in the dim outside lighting. I had pulled my swim trunks to the side and hung my cock out which was half hard just thinking about doing this. She said OMG I can't believe you're doing this but couldn't take her eyes off my half hard cock. I stepped closer as she sat on the chair and she grabbed my cock and started stroking it, making me rock hard. I immediately pulled her shirt up, grabbed those huge tits and sucked on her nipples making them hard in my mouth. I then told her to get off the chair and suck my cock. At first she said no, but quickly changed her mind and got on her knees. I have never had a mouth feel so good. My wife doesn't suck cock and I miss that feeling. Because we had to be quick, she couldn't finish before my wife came back out. Since then, we've had some very spicy texts but she has never given in. She claims she has never had a cock so big in her mouth, which is probably a lie as I'm only 7 1/2 - 8 inches at my best. To this day I keep begging her to suck my cock and let me cum on those huge tits of hers. To this day nobody has ever known how naughty we were that night.
