Standing totally naked in my sister and her husband’s home, I walked up before her and knelt down in front of her. She didn’t say a word, but just grinned excitedly as I reached out to her hips and slowly peeled her panties down from under her belly and over her hips. She held herself up and allowed me to strip the fabric from under her butt, then lifted her legs as I slid it along her bare thighs, over her knees, and off.
She folded her legs together casually, but then allowed me to slowly pull her knees to the side, keeping them together and turning her lower body so that she leaned on her side as her buttocks came off the floor and her pussy was exposed. She laid her upper body down, reaching one arm up and resting her head on it as her great belly rested on the floor and sighed with satisfaction as she felt my hand on her hip.
My erection was strong by this time, but I needed more of my sister before I could satisfy myself. I laid down on my side further down on the floor so that my head pointed toward her butt. I reached up and pulled her cheeks apart to expose more of her pussy. Her hair had grown longer than when we had been together last, but it looked right. She looked inviting. My wife, Michelle, loved it when I licked her like this, but there was something about Jen that made me hungry to taste her between her legs.
Greedily, I pressed my mouth against her warm, moist pussy and heard her gasp in delight. My lips pressed against her own hairy lips and her butt cheeks were warm against mine. I slid my tongue out and dipped it into her cunt. She was already wet with excitement. For the first time in years I tasted her fluids as they leaked out of her vagina. Her pussy lips were swollen and fleshy, and as I gouged her flesh with my tongue, I could feel her lips growing firmer as her stimulation built.
I focused my tongue on her clit and heard her gasp out an “Oh god!”. I twirled her erect nub around and then licked it straight up and down until I could feel her trembling. Her legs had begun to feel tacky as she started to perspire, and when I took my face away to look at her, I could see droplets of her clear fluid had run down her cheek and into the carpet.
I got up and scooted myself up behind her so I could put my arms around her sides while I brought my penis up toward her pussy. The sun poured in through the blinds as we lay together on the carpet in the middle of the room. She reached back and pulled my hand around her and put it on her belly and then gasped as she felt the tip of my penis touch her cunt.
Gently, I inched myself forward. My penis squished between her swollen lips and sunk into her body.
I pushed it in deeper. Jen bit her lip.
Deeper. Her hand grasped mine and held it tight on her stomach.
My body became one with hers; my penis sticking fully her quivering vagina.
Suddenly, we were both still, paused in the midst of our union.
“Do you feel him?” Jen whispered.
I smiled, feeling the vibrations under my hand. “Yeah!”
“He’s kicking!” she said. She turned her head back to smile at me and say, “He knows I’m enjoying this.”
I bent forward and kissed her, fully. When our lips parted and our eyes opened, Jen looked at me with something more than love. Now it was lust.
Obliging her, I hauled my penis down her passage, then thrust it back up inside. She grunted and laid her head back down on her arm. Her cunt felt different, now that she was pregnant. It was a tighter squeeze, as though she was gripping my shaft. It was harder work, but the feeling of her body holding me so tightly was exhilarating.
I continued to plunge myself deep into her body. My skin meshed with hers and our bodies jostled together. The glands in my body pulsed lubricant out through the tip of my penis which mixed with her body’s excretions until our genitals were wrapped with our mingled fluids. The hairy base of my shaft and my balls merged together with the course hair in her cunt as I pumped myself in and out of her until the hair of both our bodies was moist and saturated with our love.
My hand firmly grasped her belly where her child lay, an unknowing member of the new body Jen and I had become. His kicks continued as his mother and her brother celebrated their love together. I worked my other hand under her body and placed it on her belly, then moved the hand I had on top onto her breast. She gasped and moaned again as my warm hand caressed the teat that would soon suckle her child.
“Oh god, Mark, you’re milking me…” Jen gasped, feeling my fingers squeeze her swollen nipple. I was surprised to feel my fingers suddenly wet and realized what she meant. I continued to squeeze and fondle her breast, working out a few more drops of her milk. Her body had not yet started producing the milk she could yet, so it was only a minute before I had drained her. She moaned and clasped her hand over mine on her breast tightly.
She started to tremble, lightly. I continued sliding my flesh into hers. She moaned and began to shake. I felt her cunt pulse with warmth and grow wetter.
She began to whine, trying to hold back a groan, but she couldn’t help it and her loud cry filled the room as she came to an orgasm. I held her tight and worked my penis in and out between her dripping pussy lips. I could feel my balls getting wet from her cum and could barely get any friction with her this wet.
After a few moments where she strained and shook and cried out in ecstasy, she dropped her head down to rest.
The room was quiet, and the sounds of our labored breathing and the sloshing of our genitals echoed in our ears.
“Mark,” Jen said. “Think it’s going to be a while before we can do this again?” she asked, panting.
I grunted. “Yeah, probably.”
She gasped again. “Do you want to do me in the ass?”
She felt my rhythm falter and grinned back at me.
“I sure do.” I said, bending over to kiss her again.
“I thought you would. Go ahead. I don’t let Mark do it. It’s just for you, hunny.” She said.
I kissed her again and as our lips pressed together her tongue pushed into my mouth. After a few moments, our lips separated and she gave me a knowing smile. She wanted me to enjoy her however I wanted.
I slid my penis out of her cunt and reached down and positioned the tip against her anus. It was a much less elaborate entrance into her, but all the more thrilling because this was the absolute pinnacle of her privacy. Her anus was what she would keep guarded even from her husband, and she offered it to me, her brother, freely.
Gently I pressed myself against her. It took a moment where I could feel her trying to relax until I began to easily sink in. The texture of her anus was much more stimulating than her vagina. For such a simple entrance, the nerves in my penis registered an incredible texture inside.
Jen reached her hand down and put it on her hip as I slowly pushed myself all the way in. My balls and groin tucked into her butt cheeks as my dick slid up into her ass as far as possible. I began to slowly pump myself in and out of her until I felt her muscles loosen and it became easier.
It had been so long since we had done this. There was no doubt we were both thinking about the first shower we had taken together and how this had been the result.
A moment ago we had been one body. We were still so now, but it was a different body. We had been two equals, united in love. Now, she had submitted herself to be used for my pleasure. My sister had opened up herself to assuage my lust, and I was hungrily devouring what she offered me.
