My Latvian Sister-in-Law Part 3 (MF, cheating, risky sex, anal)

Readers: you don’t have to read the previous parts if you don’t want to. This one stands on it’s own. The other 2 are great, though.

In the previous parts, I thought I would avoid saying the names of my wife and brother. Now I can see that it’s getting confusing without knowing names. So, here they are: my wife is Cammie, my twin brother is Tim, and I am Tyler.

In the last part, I explained how my wife, Cammie, gets turned on when I flirt with Anna, Tim’s wife. Anna and Cammie are best friends. Anna is from Latvia and was fooled into marrying Tim, who is a rich, selfish business man that treats her like his property. After 18 months of trying, Tim still couldn’t get her pregnant and he threatened to divorce her and let her be deported. In Part 2, Cammie let me fuck Anna for the first time and now I fuck both of them regularly. All three of us love this arrangement. I got Anna pregnant because I’m fertile and my brother is sterile. My brother doesn’t know what’s going on.

When Anna got pregnant, Tim became surprisingly supporting of Anna and stopped threatening to divorce her. He still treated her bad a lot, but at least her future in our family was secure. To avoid being caught in the affair, Anna made sure to be especially good to Tim. She seduced him whenever he was home from his business trips, even if he came home in the middle of the night. Each time, he never suspected that my cum had been in her cunt earlier the same day.

Luckily, neither Cammie or Anna had morning sickness. Anna kept coming by our house to hang out everyday. The girls would always plan their sexual encounters with me behind my back, and I started getting used to being “surprised”. Usually, Cammie would make up an excuse to leave for a few hours and tell me to “be a good boy” while I was gone. Then, Anna would seduce me with new lingerie or a clever sexual situation like “needing a towel” in the shower. Later, Cammie would ask for a play-by-play description of what happened and would give me my “score” based on how hot and sensual I made it for Anna. Usually, Cammie would want me to reenact the sexiest parts with her so that she “could feel how good it was”. It worked the other way, too. If I had very good sex with Cammie, then she would tell Anna, over lunch what I did and Anna would want to repeat the same thing with me. Without me knowing, they would plan these whole encounters and I would just do what they wanted me to do.

Over the next six months, those pregnant women got so incredibly horny. I let them use me to play out any fantasy that they wanted. Every sexual position, every role play, every sex toy–I must have done it all. They wanted me to fuck them in he laundry room, on the kitchen counter, in the car in the garage, and on the patio furniture on the back porch (we had privacy walls in the back yard).

Once, I learned that they had a competition about who could have the most orgasms with me. Not knowing that it was a game, I gracefully accepted Anna’s requests for me to suck her pussy over and over again for an hour. Three orgasms. Cammie wanted the same thing two days later. Four orgasms. Cammie won.

A week later, they had a new game–who could give me the most orgasms. Again, with me not knowing what was going on, they purposefully refrained from sex for three days before Cammie seduced me. By alternating from deep-throat blow jobs and wild cowgirl rides on my cock, she made me cum three times.

Anna was determined to beat her. They both withheld sex from me for five days. Anna would tease me by wearing revealing clothing, talking about sex all the time, and finding moments to secretly make out with me, but not have sex with me. It was driving me crazy that I didn’t know what was going on. Finally, I couldn’t take it anymore and I begged her to fuck me. During my lunch break, she took me to the bedroom and put her sock on the door (the sign the girls had for each other to not interrupt). Four ejactuations! First was a blow job, then she rode me with an amazing twerk that I couldn’t believe a pregnant woman could do, then she gave me a hand job with lots of lube, and, finally, she let me doggy style her in front of the mirror for more than fifteen minutes until I came one last time. Anna was victorious!

The autumn season came and the holidays were approaching. Every year for Thanksgiving, my brother Tim always insisted we had Thanksgiving dinner at his house because it was so much bigger and more elegant. All three of us were dreading this dinner because we all hated Tim.

I could tell the girls were plotting something around this event. Normally, I let them having their fun planning things, but this one made me nervous because it involved my brother. I asked them, point blank, to tell me all the details.

“One thing I hate about Tim is how possessive he is,” explained Anna. “He has a special room in his house that I call his ‘vanity closet’. It’s not actually a closet–it’s supposed to be a guest bedroom. Inside, he has wardrobes upon wardrobes, shelves upon shelves, all full of clothes and shoes. He spends over an hour in there every day, trying on business suits, looking at himself in the mirror. And I’m forbidden to go in there–ever! What the fuck is that? I’m his wife.”

“Okay,” I said. “So, what’s that got yo do with Thanksgiving dinner.”

Anna and Cammie smiled. “You and I are going to fuck, hardcore, in that room. And, hopefully, leave a puddle of cum on the carpet.”

They had it all figured out. Each of us would have an alibi. Before dinner while the turkey was cooking, I would say that we left a pie at our house and I had to drive back and get it. Anna would say that she was feeling pregnancy fatigue and wanted to rest in their bedroom. Cammie would talk to Tim in the kitchen about his work (he could talk for hours about his companies). We would set up a baby monitor so that we could hear everything they were talking about.

The plan was perfect and I was all in. Soon I would be fucking my evil twin’s hot wife inside his own personal sanctuary while he peeled potatoes.

The day arrived and Cammie and I came to Tim’s house. Tim and Anna were already there, obviously, and so was my mother, Margaret. We all visited in the kitchen for a few moments.

“I’m so glad that both my daughters-in-law are pregnant at the same time,” said my mother. “The cousins will love to play together.”

“Yes, the cousins will be so close!” said Cammie. “Like siblings!”

I glared at Cammie. She grinned. Anna blushed.

Tim stood in the back of the room, obviously uninterested in anything that was happening.

“Oh, no!” I said. “I left the apple pie at home. We worked for hours to make that yesterday.”

Tim scoffed. “Don’t worry,” he said. “I’ve got a frozen one we can thaw.”

“Frozen!” said Cammie. “You know homemade is better than store bought. It’s my grandma’s recipe.”

“She’d better go get it,” said my mom. “It’s a tradition and you can’t break it.”

“Naw, I’ll tell youbehst. I’ll get it. I’m sure Cammie wants to stay and talk.”

I snitched a hot dinner roll before I went out the door. Cammie suggested that they peel potatoes while Tim told them all about how business was going. Anna said she was tired and wanted to rest. My mom didn’t care for the conversstion either and left to her guest bedroom to read a book. So far, everything was perfect.

I walked out the front door, drove my car around the block, and parked it on the street. Then, I walked to Tim and Anna’s house, sneaking in through the door to the master bedroom. Anna was there holding the baby monitor. We could hear Tim complaining about how his emoloyees wanted to be paid too much.

Anna went first into the hallway and then into the vanity room. I followed her a minute later.

When I walked in, the lights were off, but Anna had turned on her cell phone flashlight. She was totally naked-her belly was slightly round from the pregnancy and her breasts were large and firm.

I stripped off my clothes and she embraced me. We were making out, I groped her breasts, she grabbed my ass and pulled me close so my cock slid between her legs.

She pushed me against the wall and said “put on this jacket”. It was an expensive suit coat from Italy. I slipped it on.

She pushed me down and immediately slid my hard cock into her smooth pussy. I cupped her firm breast, which were bigger than my hands, and softly pinched her nipples as she rocked her body up and down on my long shaft.

I noticed a distressed tone of voice on the baby monitor. “He’s coming! He’s coming!” Cammie said.

I turned off the baby monitor and Anna turned off the flashlight. We both dove under a large shoe shelf that had space for both of us underneath. I was still wearing the jacket, and I turned so that the jacket faced outward and Anna was totally hidden. However, my naked legs were only partially covered up my a laundry basket.

Tim entered the room, but didn’t turn on the light, thinking the light front the hallway was enough. Apparently, he had spilled something on his shirt and felt he had to change it immediately. He spent a few minutes deciding which new shirt to put on.

Anna and I were face to face, trying not to breathe. Then, Anna started stroking my cock, just with her fingertips at first, then she started completely jacking me off.

“Are you crazy?” I thought.

Tim didn’t like his first shirt, so he tried on another one. Anna pulled my cock closer to her crotch and started rubbing the tip against her clit.

Finally, Tim was satisfied with his shirt and started to leave. Anna let out a very, very soft moan. Tim paused at the door, then shrugged and left.

We turned on the baby monitor and waited until we heard his voice in the kitchen again. Then, we climbed out from under the shelf and I got on top of her, desperately wanting to fill her pregnant pussy with cum. She started moaning louder, but I felt we were safe because the walls were so sound-absorbent.

She pushed me off and climbed on top. “Tyler,” she whispered. “I want you to come in a different hole this time.” She pulled me in and slowly inserted me into her ass.

It was so tight, but her whole body lit up in excitement. She had obviously prepared for this with lots of lubricant.

“It feels so good, like I’m stretching out in a good way,” she said. “I can feel it pressing on something good inside.”

She rode me very slowly and delicately. God, it felt so good! It squeezed me at just the right pressure. I rubbed my hands on her round belly and squeeze her firm tits.

My cock erupted with blasts of cum deep inside of her. She immediately pulled out because the throbbing was too much for her sensitive ass. I twisted to the side. Loads of wet, dirty cum spilled onto the carpet and onto the lining of the suit jacket I was wearing. Anna patted me on the back and said, “Good job!”

We starting putting our clothes on, making sure to listen to the baby monitor. Everything was good.

After we put out underwear on, the door opened. It was my mother. Anna and I froze in place.

“Oh I’m so sorry Tim!” She closed the door all but a crack. “I didn’t know you and Anna were…changing your clothes in here.”

Anna and I stayed silent.

“I just wanted to ask if I should check on the turkey.”

“No, mom, I’ve got it,” I said. “And, one thing, mom.”

“Yes,” she said, sheepishly.

“Let’s agree not to bring this up ever.”

“Tim, I promise that I will never, ever remember this moment for the rest of my life.”

She paused for a moment before leaving.

“Hope it was good, Tim,” she said, chuckling, then she left.

The rest of the dinner was boring and uneventful. The turkey was dry. The conversation was drier. No one drank wine out of concern for the pregnant ladies. Tim left the table first to watch football in his room by himself. The rest of us played cards with my mom and ate pie.

A few months later, the babies were born. They were both sons. Cammie delivered first. While she was recovering, she asked me to fuck Anna as often as possible “so the baby comes sooner”. Weeks later, Anna delivered, just when Cammie was recovered and hungry for sex again. The three of us loved both babies and took care of them together. Tim was away on a business trip and missed the birth, but I was there.

After three years, Tim’s lawyer issued divorce papers to Anna because he wanted to marry a secret mistress that he had had since before Anna conceived. Anna received a very large alimony and child support. They were set for life.

Anna and her son bought the house right next to ours. We spent so much time together that the neighbor’s probably thought we were polygamists. We’re not. But, I’ll confess that Anna and I kept having sex on a regular basis like we were teenagers on a crush. Cammie loved it.

Eventually, Anna found a man named Dave that was okay with the open marriage that we had established. They were married and I was still allowed to sleep with her whenever she wanted. But, Cammie thought Dave was really attractive and I caught her flirting many times. After a few months, they started a tryst that surprised me and pushed my sexual life beyond anything it had already experienced.

But that is another story.
