Fucking My Wifes Sexy Big Tit BBW Friend

My wife has this sexy thick friend she"s known since a few years before we met you can see her tit pics in my galleries. She has a fat round ass big sexy legs and an amazing big set of tits with gorgeous big nipples. I have wanted to fuck her for 15 years we always flirted back and forth a little and she'd occasionally send me a sexy pic of her perfect big girl tits. Over the last 2 years her girlfriend and her never have sex and we've gotten way more into teasing and dirty texting each other. About 6 months ago she started telling me about how much she wants to have a second baby and of course I used that chance to mention how much fun I would have helping her out with that. Her reply was that she would let me get her pregnant. It got me extremely turned on to hear that from her I did assume it was just more of our flirting. Well the next week I got a text saying "so when are you gonna knock me up" I was a little shocked and a lot turned on but I had to probe around our texting conversation for a while to be completely sure she was for real. After a few hours of occasional back and forth messages about it she very bluntly sent "I'm not playing around at all if you're willing to try to get me pregnant you can fuck me". We both knew how badly I had wanted to fuck her for years now so I had no reason to even reply to that she also made sure to remind me it had been 8 years since she had dick. We started meeting a couple of times a month for a few hours on an evening her girlfriend didn't get home until 9 or 10 and its been fucking amazing! She loves having her big perfect tits sucked and played with or having her nice big nipples pinched while I use my free hand to rub her clit and finger her pussy until she has her first cum. The most fun thing about fucking her is once she's had her first cum I can fuck and cum inside her pussy over and over for as much time as we have left to play. Her pussy is super tight I'm so addicted to the way it squeezes my cock and makes me lose my first load in minutes but we're both so turned on by our secret fuck sessions it usually doesn't slow down there. She'll start talking dirty like asking how much I like fucking my wifes friend and damn does it work. I keep pumping in and out of her tight cum filled pussy everytime until I'm emptying another load in her pussy. It's been 4 months since we started and I havent knocked her up yet it might not happen at all shes close to 40 but shes already said we can keep trying for as long as I want. I wouldn't have ever guessed that I would get to fuck my wifes friend one time I crushed on for 15 years now we fuck in the bed she share with her gf of 13 years and her only rule is dont pull out!
