Monica, My Loving Sister

...

For the next 3 days, I walked on eggshells. Both tried to behave normally, but the tension was enormous. We ate together, joked about the baby, and chatted about the weather, but we avoided discussing the elephant in the room.

On the morning of the 4th day, she was in the kitchen, and her phone rang. She picked it up, "Hi Larry. Are you returning home the day after tomorrow as planned?"

I couldn't hear what he was saying, but Monica's face told me everything I needed to know: Her husband was staying away. Before hanging up the phone, I heard her say, "Don't misunderstand me. I do appreciate your efforts supporting our family, but this wasn't the deal. You weren't here when your daughter was born, you were not helping at home during the time I needed you most, and now you tell me you will stay there another 2 weeks. You do what you want, but I may do the same!" Then she slammed the phone.

I approached, hugged her, and said, "Monica, that's OK. I can stay longer and be happy to help until Larry shows up."

She smiled bitterly, "Honey, that's what I was afraid of."

What did she mean?...

Later, the same day, I noticed Monica changing before my eyes. She no longer wore the usual long robe. It was replaced with thin blouses with tiny nipple shields. Her massive breasts swayed freely underneath her blouse, causing my cock to get hard almost all the time. Red lipstick appeared on the second day, highlighting her luscious lips. And then I became aware of the way she glanced at me. While before it was more like sneaking short peeks at a time, now it had become longer unabashed stares. She saw me noticing it, but her eyes continued focusing on me, as if wanting me to start something. I was too conflicted. Knowing Monica was upset about Larry, I was scared to make the wrong move.

On the third evening, I was sitting at the table, pretending to watch TV. She was nursing Tiffany on the sofa. Suddenly, she said, "Soul, please come here."

I sat by her side, ogled her cute face, and stayed quiet.

"Tiffany uses more milk than before but still does not need more than the content of a single boob. My other breast is full and achy. I am tired of pumping it all the time and dumping it in the bathroom. Do you have an idea what I can do about it?"

"Monica, please, don't tempt me. You know exactly how I feel, and we both understand where it will lead to..."

"Soul, I struggled with the same subject for days. My brain gave up the first time you sucked me, but later I made up my mind we were nuts to even think about it. The second time, I became hornier and ready for anything too. In both cases, we were saved by god's bell - Tiffany. I thought it might have been god's sign to stop. However, the days without your lips on my breasts felt longer, lonelier, and less pleasurable. I missed the feeling of being a desired woman again. The last straw was the phone call from Larry, telling me he got stuck in California for another 2 weeks. If his work is so much more important than his family, I do not see a reason to suffer. Both of us feel the same. My initial reservations about the age difference and being blood-related are no longer a major issue. Do you still find me attractive despite my cow-like appearance?"

I hugged her, kissed her red lips, and whispered, "First, I like cows and want to treat cows in the future. More importantly, your tits are absolutely fantastic, and I mean shape, size, and taste. Your whole body is simply perfect. You'll make me the happiest man alive if I can have you. Each night, I dreamt about you and hoped you'd open my door and say the same thing you just said..."

She blushed and murmured, "Will you be nice and suck on my other nipple? It waited too long for you."

I smirked, "Only if the milk is free."

Monica giggled, "Judging by the way you milked me the other times, it shouldn't be free. This time, you'll have to finish what you started..."

I sighed, "If I do not have another option... "

She grinned, "you are such a jerk. Can't admit you love the idea?"

"I'll never give up to a woman! This is a man's world, and women have to abide by OUR rules."

She gazed at me for several seconds and said, "I thought you were better than Larry. I see I was mistaken. Please, pack your stuff and leave."

I knelt before her, "Monica, forgive me. It was a stupid joke. I love you and, of course, will do ANYTHING..."

She stood up, went to put the baby in her crib, and blurted, "Prove it to me. Undress!"

I hesitated. Not so much due to shyness or feeling insecure about my body. It was because my 7 incher was already pointing straight up. With no other choice, I removed my clothes and stood in front of her naked.

She sat down, and her eyes explored my body, focusing on my groin. She licked her dry lips and announced, "Not bad, bro. Now lay on the sofa and milk me in the nude. I want to observe your reaction to sucking my tit and touching my body."

"Yes, ma'am."

I did as she said and, seconds later, enjoyed the fresh, sweet taste of her milk. Like before, her head rested on the chair back, and she shut her eyes. Her face displayed immense pleasure. My palm began massaging the round tit slowly, and soon her groans started. My hand trailed down, slipping inside her skirt and panties, eventually reaching her cunt. Her respiration seemed more labored, and her legs opened. My 2 fingers invaded her wet pussy and began rubbing the front wall. I felt her tiny palm massaging lightly my pectorals. I directed the hand toward my stiffy and gently arranged her body to lay supine on the sofa.

Her hand started bobbing me lightly, and she whispered, "Honey, you were so good sucking me before. I wish to return the favor."

I turned slightly to facilitate her access to my pole, hoping not to cum too early. Monica's pouty lips enveloped the head, and she licked it. She removed it from her mouth and inspected it. I heard her whisper, "Please, don't grow bigger. You are already longer and thicker than the one I am used to giving head to."

Next, a drop of precum leaked from my slit. She grinned, "Oh, buddy, your Master sucked my milk, and you wish to let me taste you too." Her little tongue tasted the fluid, and she murmured, "Mild but tasty appetizer. And now for the main course."

Subsequently, her mouth opened wide and engulfed the first inch of my prick. Her face advanced steadily forward, taking my organ inside, inch by inch. I stared in awe at how her expert mouth slowly concealed it. The feeling in her warm, moist mouth was extraordinary! My member was buried deep in her throat when her oral dance started. The girl was a real expert: She did it slowly and methodically, ensuring all of it was inside before pulling it out while 'Hoovering' it. After less than 2 minutes, my spunk was ready to gush out. I warned her, "Love, you are too good. If you continue, I am going to explode in seconds!..."

Her hand rose in a sign of thumb up, and her rhythm accelerated. I erupted in her pharynx with tons of seed. Monica calmly swallowed it as it came and showed no signs of distress. My prior oral experience wasn't vast, but Monica was by far the best, and much better than I expected.

She made sure to milk the remnant from my urethra and then gazed at my face and smiled, "Little brother's factory produces a tasty cocktail. Knowing it has health benefits as well, next time you wish to feel my mouth around it, let me know. We have another hour until Tiffany wakes up. Get some rest before ravaging my body."

"Monica, your mouth performed a miracle, and I came like gangbusters. However, I do not need to rest. Your body is so sexy that thinking about our next step was enough for my cock to start climbing again. Is it OK if we move to the bed?"

In my mind, I could imagine our sexual encounter in countless positions, but I wanted the first one to reflect our love. So, missionary was the plan.

We lay face to face, and I kissed her gently, tasting her. Her lips parted, and let my tongue slip into her mouth, exploring it. My large palm barely covered her round mammary. I kneaded the firm tit, pinching lightly her hardening nipple.

She whispered, "Please, honey. Sucking you made me very horny. I wish my first orgasm to happen when you are inside me, so spare the prolonged foreplay for other times and put it in."

Monica's breathing and pulse rate were sky-high. She was obviously very aroused. I could not resist one more thing, "Girl, I came already, and I am in no hurry. If you want me to do it in a certain way, tell me in detail what's your wish."

Her body wriggled under me, and she screamed, "Fuck me! I want you to penetrate my pussy with your cock and make me yours. Fill me with your slimy goo and continue ramming it into me until I see stars!"

I whispered in her ear, "Sis, now you're talking. Here I come!"

Knowing her cunt was drenched, I shoved my member all the way and began plowing her vagina. It was still somewhat dilated after her delivery, but my wide girth was enough to fill her pussy, creating adequate friction. Monica lasted about a minute before starting to howl and cry. I intensified my strokes, getting a lot of pleasure from watching her grimaces and having a front row view of her jiggling tits.

I was in no hurry. I pounded her pussy relentlessly, now and then whispering in her ear, "You are a bitch in heat. Is this what you wanted? Getting fucked like a cheap whore?"

She screamed her lungs out, "YES! Your cock is filling me so good... I want it in my cunt forever!"

"Well, girl, it's time for me to climax now." Soon after, I poured my spunk deep into her vagina while growling like a wounded wolf.

In the following days, our daily schedule included feeding, changing Tiffany's diapers, and nonstop sex. Actually, now and then, we stopped to eat, sleep, or go to the bathroom, but those activities occupied much less time than our sexual escapades. I found out Monica liked everything about sex, including various positions in different places, but this discussion belongs to another chapter.

Our last day before Larry's arrival, we spent hugging, kissing, and having sex 'only' twice. Before leaving, I told Monica I loved her and was hoping to see her soon. With tears in her eyes, she mumbled, "Soul honey, I love you very much, too. Unfortunately, with the baby's constant needs, it will be impossible for me to visit you. I think that Larry will feel guilty and stay around for a while. But we'll keep in touch by e-mail and phone."

...

In the months that followed, we connected mostly by e-mail. Occasionally, she complained on the phone that, initially, Larry behaved like a perfect husband - He spent time with her and Tiffany, helped around the house, and they had sex twice a week. Gradually, everything deteriorated. He worked many hours a day, stopped helping with house chores, and the sex diminished to no more than once every 2 weeks. I had no idea what to do about it but promised to think of something.

One evening in March, I got a call from Monica, "Soul honey, I think I found a solution. I am pregnant again. The conception was in early September, so my delivery is expected in early June. Knowing how much Larry hates helping me with Tiffany, I think I can convince him to go on another assignment for several weeks, trusting my little brother would agree to help. Interested?"

"I wouldn't miss it for all the gold in Fort Knox!"
