Sister's Secret Sin

It had all started with a simple question. “Do you want me to fuck you in your sister’s house?” I whispered in her ear as we sat there at the McDonald’s in Susanville. I watched asher freckled cheeks turned a bright red, my dark brown fingers trailing up her arm. She shivered and just smiled as I stopped walking up her arm. Her younger sister Cristina sat at the other side of the table and acted like she didn’t see what she just saw. “I have no desire to know what he just asked you,” she said eating some fries. I chuckled and looked back at my bride of three-going on four years, my girl of eight. My high school sweetheart. “Are you going to answer me?” There was a brief cough as she tried to swallow a bite of her sandwich. “No,” she quickly said. “Not right now.” “Oh, not right now,” I asked out loud. “But maybe tonight when you’re crawling on your hands and knees towards me,” I whispered. I sat back and just watched her turn red again. She nodded with a small but naughty smile on her face. We were traveling to visit her family out in Cali. Her older sister Tiffany, her husband Caleb, and their kids. It would be the last time we could go up to see them before Jean had our little boy. We were both hoping for a little time to ourselves, but we knew that it would be a little hard. The two of us would be sleeping in the living room. On an air mattress. And as I just said, she’s pregnant. Not the most optimal of situations for lovemaking, but I knew we’d make it work. To make the boring part of the story pass by, Sunday when we drove up there was a bust. Both of us were too tired. Monday, she passed out before I even got into bed after promising me another earth shattering blowjob. Tuesday is when I started feeling that separation. We hadn’t made love since Saturday and after expecting to be home that night, we found out the pass had been closed down due to snow, I tried to handle myself when she went to the park with her sister and the kids, but it didn’t pan out. When she got back to the house, I could tell she was feeling it too. She does this thing where she’ll start rubbing my neck and telling me every five minutes that she loves me when she’s that out of it. My response always is, “No. you’re just horny.” To which she smiles while still rubbing my neck and says, “Doesn’t mean I don’t love you.” I love this woman. She understands my humor and just plays right along. She apologized for not acting on her promise to give me a blowjob. I just kissed her and told her she was tired and that I understood. Later that night when we’re all alone I got her to sit on my lap on the couch and the moment she did the two of us laughed. I had written a post on marriage heat about not being able to handle myself, and I let her read it. In my post, I mentioned possibly going at it on the couch but that theory had just been shattered. But that didn’t stop me from kissing her neck and making my way down to her chest. She already wasn’t wearing a bra underneath her spaghetti strap, and so I whipped those big titties out and started sucking on her nipples. She moaned as quietly as she could, not wanting to wake up the rest of our family. But the moment didn’t last long when my son decided he needed to kick me in the chest. Jean giggled when I stopped tugging on her nipple. I let it go with a little pop and smiled. “Hi, son! How are you?” I asked with my lips on her stomach. His answer was to kick me in the mouth, and the wife jiggled her cute self as she laughed. I pulled her down for a kiss, and she kissed me as two young expecting parents do, with all the love in the world. As she got off me, I took my hand and rubbed her yoga pants up the leg until I was caressing her awaiting slit. “Take off your clothes,” I whispered. She smiled and did that sexy crossed arms thing I love as she started to take off her shirt. Her titties fell out above her beautiful bulging stomach. My hand trailed up from her bellybutton to her already pulsating nipples, and she sighed as I flicked them around. She took off her yoga pants, and I slid my hand into her slit again and felt her juices drip onto my fingers. Smiling as I quickly played with her clit, I had her lay down on the air mattress. It made a squeaky noise, and I made another mental note I’d have to be gentle tonight. I stood over her and took off my clothes, my manhood pulsed in midair as if he was searching for her. Grabbing a pillow, I placed it under her hips to lift up that awaiting wet pussy of hers. Her eyes told me she was waiting, and her lip quivered as she fought the urge to bite it. My penis in hand, I took my head and played with her clit. She moaned and lifted her hips as her legs shook. This time she couldn’t stop it and bit her lip, giving me a pleading look in her eyes. For me, that was all the torture I could stand, and I slid myself in trying my hardest to hold my moan. My hands down on each side I started moving my hips and felt her wet pussy hold on tight. I love my wife, and I watched her try her hardest to not make noise, but she still let the occasional moan slip through her pretty lips. The lousy air mattress creaked underneath us with each thrust, and the two of us shared a secret smile with one another amused. It didn’t take long for her to climax. She arched her whole body off the mattress and the pillow, her legs shook starting from the toes and going all the way up through her body. Her mouth was open, and her lips trembled as she held back her need to cry out satisfied, and when it was all over I could feel how wet she had become. I was already near my peak as well and kept going. It was slow and purposeful as with each thrust I watched each and every one of her reactions. Sometimes we would lock eyes as I pulled back out but then they would be closed the moment I was back in. I moved my hips counter clockwise while pushing in deep, and she grabbed onto my arms digging her nails into them. I was almost there, and I held it back just a little longer to make sure she was with me and then I let it go. A grunt came out of my mouth but I stopped it instantly as I realized how loud it was. My beautiful bride launched herself off the mattress. Her whole body shook and mine did too. The pressure to stay quiet had intensified our orgasms and the two of us locked eyes as we jumped off the cliff together and relaxed right there in my sister-in-law’s living room. We weren’t home, but my did fireworks go off. Once we had cleaned up she fell asleep in my arms as I held her from the back caressing her stomach and feeling our son kick every once in a while. The next few days went by and finally Saturday showed back up. She stood there as her sister went and got the car seat for our daughter out of her car. “We’re going to be in our own bed tonight,” I said as I held her around the waist. With her arms wrapped around me she smiled. “I know, I’m excited.” “I’m going to do so many things to you tonight,” I said. Her eyes glazed over for a moment before I started to kiss her neck. She hissed in my ear and her hand found itself locked in my curly hair. “Someone is horny,” I whispered with my lips still on her neck. She didn’t have to reply because I didn’t give her the chance when I grabbed her big ass cheeks and gave them a squeeze. We headed to the car after that and started on our journey home. At one point I told her that she was going to be on all fours because we wouldn’t have been able to do that on the air mattress. Especially not the way she likes me to pound her. My hand would sometimes crawl up her leg. When I would watch her glancing at me my hand would ravage her slit from outside her pants. The look on her face as she would try to stop my hand only to let me continue. Her mouth wide open as she stifled her screams for fear of waking up our sleeping daughter. My little submissive she is, I told her to take out her tits and play with them. There was a pause as she thought about doing it since we were on a one lane highway but she said no. I laughed, teasing her because she had actually considered it. “They would see,” she said motioning to the cars driving the other way. “But, I can play with your penis,” she said reaching over and stroking the bulge in my pants. “Be my guest,” I moaned. I had to force my eyes to stay open as she tickled and fondled the man piece that made her the mother I’m proud of. The teasing the whole drive was fun but it wasn’t enough and eventually we got home. I met her in the kitchen as she made herself something to eat. My hands wrapped around her from behind. I nibbled her ear and my hand slid into her pants, past the panties. Her still growing bush tickled my hand as I caressed her awaiting slit; the bottom hairs were moist with anticipation. She breathed heavily when my other hand cupped her exposed ass cheek as it slid out of her pants. Her pussy was getting so wet I began to hear her splooshing noise I love so much. Smiling as I quickly played with her clit, I had her lay down on the air mattress. It made a squeaky noise, and I made another mental note I’d have to be gentle tonight. I stood over her and took off my clothes, my manhood pulsed in midair as if he was searching for her. Grabbing a pillow, I placed it under her hips to lift up that awaiting wet pussy of hers.
