I've known Ana literally since she was a teenager. My brother started dating her when they were sophomores in high school. Over the years, Ana and I developed a close relationship. I was the big brother she never had. She was my biggest fan during the last two years of my high school athletics career, and she came to me when she was deciding which college to attend. I was more than her boyfriend's big brother. I was hers as well.  

I was happy and proud when my brother married Ana. I knew she'd be a good wife, and I was happy to have her in the family so we could continue the friendship we had developed through their years of dating and their eventual wedding. I was ecstatic when they bought a house in the same city so we could all be together as a family. My brother got a great job as a marketing manager for a company, and they settled into married life well. Ana and I continued to talk and advise each other, and continued on the foundation we had built.

So it didn't come as a surprise when my phone rang, and it was Ana. What did surprise me, though, was how she was absolutely beside herself. Through her tears, she said she had found something out, and could I come see her right away? My wife and I only lived a few blocks away, so it didn't take long to get there.

Ana met me at the door with tears and a hug that I didn't think she'd ever release. She lay her head on my shoulder and just sobbed. Finally, I was able to get her calmed down enough to talk to her.  

"I-I-I found something on the laptop. I was looking for some receipts for rebates, and a Teams message popped up. It is from Andrea," Ana said to me through tears.

Her hands shaking, Ana turned the laptop towards me, and I read the message: "Thanks for last night. You are real straight-laced in the office. I didn't know you could be that dirty. My goddd. I can't wait until next time to see you."

I sat there stunned, like I'd been punched in the gut. My brother, though I loved him, had really, really hurt someone I considered my best friend. I was livid and, in my mind, vowed revenge.  

I looked at Ana, who by this time was calmed down. I could see a look in her eye. I thought she was thinking the same thing. She laid a hand on my thigh and said, "If he can do it, so can I."

I looked at her with a mixture of shock and unbridled lust. She looked fabulous, and I couldn't believe my brother thought he could do better. Before I knew it, Ana was on her knees in front of me, in her kitchen, in the house I'd helped my brother remodel, and she was about to suck my dick.

And suck my dick she did. God, her mouth was velvet. Licking from the root to the tip and looking up at me, I could see in her eyes that she truly enjoyed giving head.  She had my shaft deep in her throat and was working her throat muscles while she expertly stroked my hardness. I reached down to hold her hair in my hands while I rolled my head back and let out a groan.  

She was swirling her tongue around my tip and tugging her shorts down at the same time.  She released my dick and looked up at me, "I want you to fuck me, bareback, and cum inside.  I want my revenge."

Ana stood up and pulled her t-shirt just up above her 36C tits and took my hand. Wiggling her ass, she led me to the bedroom she and my brother shared. Admittedly, I had lusted after Ana for years, but I resisted. After all, I considered her my best friend, and she was married to my brother. But when she lay on the bed, lifted and spread her legs, and looked at me, all resistance was futile.

"Are you mad at him for hurting me?" She asked sweetly.

"I'm fucking livid", I responded.

"Then take your revenge.  FUCK me!"

I was between her legs before the words came out, and balls deep in one thrust.  Ana gasped, and a guttural moan escaped her lips.  Her tits were bouncing as I rocked my hips and my balls slapped against her.  

"Oh GAWWWD, yesss, oh fuck so good.  FUCK ME, FUCK ME, OH FUCK!"

The sounds of our bodies slapping together echoed through my brother's marital bedroom as I had my way with his wife.  She had her hands on my ass, begging me to push deeper with each thrust, and was arching her hips.

"DEEPER, HARDER, FUCK ME!"

I felt Ana's cunt begin to swell, and I pulled out just as she began to gush.  She was still cumming when I flipped her over.  She put her face into the pillow and extended her arms outward as she lifted her ass up.  With one hand on her hip and the other in her hair, I slammed into her pussy and thrust deeply.  

"UNNNGHHH GAWWWD," Ana moaned out. Her verbal excitement and the way her pussy gripped my dick fueled my lust, and I followed her orgasm with one of my own, shooting a huge load deep in her forbidden pussy.  

"AHHH, oh my God, that was amazing," I was able to croak out as I pulled out and lay down next to Ana. She cleaned my shaft and then cuddled into my shoulder.

"Mmmm, thank you, baby, you've always been so good to me," Ana said as she circled my nipples with her fingertips. We glanced at the clock and realized we had a couple of hours before my brother got home.  We fucked twice more, and I deposited two more loads inside her needy pussy.

As I was dressing to leave, I looked down at her. "Now what?" I asked.

"Oh, trust me, I have a plan," was her reply, with a sheepish grin.
