As I lay in the bed pondering all the questions that arose after I noticed the open door, I could hear Rachel's soft, rhythmic breathing in the bed next to me. She was completely out, satiated by great sex we just had. Normally I was the one most likely to fall asleep right after sex (like many men) but this night, with all the thoughts running through my brain I could not fall asleep. I could feel pressure on my bladder, and decided to make a quick trip to the restroom, so I eased quietly out of my bed and walked softly down the hall. I didn't hear any sound from the other bedroom, and assumed Sandra and Kelly were fast asleep.
I stepped into the bathroom, feeling the cold tile on the bottom of my feet, switched on the light and closed the door. After doing my business, I grabbed a washcloth and some soap, and washed off my well-used cock and balls. As I was drying off, out of the corner of my eye I noticed the door slowly swinging open. I turned to look, and saw my sister, Sandra, standing before me in a little baby-doll nightie.
"Hey little brother, how's it hangin'?"
Before I could verbally respond, my cock sprang to life as I stared at my sister's milky white globes overflowing her lingerie.
"No need to answer, I can see you're doing more than just hangin'", my sister joked as she watched me rise to the occasion.
Sandra took a step into the bathroom, and closed the door behind her. She reached her hand forward and gently grasped manhood, sending shivers up my spine.
"I've been thinking about this hunk of meat all night, and just haven't been able to sleep" she said as she dropped to her knees on the floor in front of me.
The feel of her velvety smooth tongue as it traced the underside of my cock was indescribable. My manhood was jerking slightly with each beat of my heart, causing my dick to bounce up and down on Sandra's tongue as it wove patterns around my hearty Italian sausage. I loved the look in my sister's eyes as she opened her mouth wide and swallowed me down – pure joy and admiration seemed to shine from her eyes and her head bobbed up and down on my cock.
Even though I'd busted a nut several times already in the last 24 hours, I couldn't take much more of her ministrations. I wanted to bury my cock her pussy, and to feel her clamp her muscles around me as I thrust my cock into her pussy the way Cinderella slid her foot into the glass slipper. I grabbed Sandra by the shoulders and pulled her to her feet. I turned her around, and bent her over the vanity as I pushed her nightie up, exposing her heart-shaped ass.
I spread her legs and slowly slid my cock into warm, wet snatch, watching it slide in inch by inch in the reflection from the mirror. At first my strokes were long and slow, as I reached around to massage my sister's large melons and to pinch her distending nipples. I loved being able to watch Sandra's eyes roll back in her head as my cock hit bottom and my balls slapped against her clit.
As her breathing began to quicken, Sandra leaned her head back toward me and whispered to me.
"Fuck me, fuck me little brother. Fill your sister with your seed."
Her words of encouraged me drove me to fuck her harder and faster. My thighs were slapping against her ass with each vicious stroke of my cock. My balls were swinging forward and banging against her clit on every down stroke.
"That's it, fuck me harder, FUCK ME HARDER" she yelled, as I continued my onslaught.
My hands were on her hips, pulling her back toward me as I forced my cock deeper and deeper into her hot, wet, pussy. I grabbed her by the hair and pulled her head back toward me and kissed her hard on the lips.
"You like getting fucked by your little brother, don't you?" I whispered into her ear.
"You like feeling your brother's big cock sliding in and out of your cunt, don't you?"
"Answer me", I demanded and gave her a slap on the ass.
"Yes, yes, I love feeling my brother's cock fucking me." "Please, please fuck me harder" she implored me.
I spread my legs and got my feet set firmly as I began to jackhammer my cock in and out of Sandra's pussy. I could feel the muscles of her pussy contracting around my cock as her head lolled back and forth as she was rocked by an orgasm. Just as her orgasm was receding, Sandra reached back and squeezed my balls gently.
"Cum in side me little brother, fill me with your spunk, make me a mommy" she pleaded as she squeezed my balls again.
Her body was slick with sweat as I grabbed her hips and made one last deep thrust, and unloaded a torrent of cum into her pussy. My body spasmed again and again as I filled her with my baby batter. When I finished cumming in my sister's snatch, I pulled my semi-hard cock from her pussy with a noticeable squelching sound. As soon as I was out, Sandra dropped onto her back on the floor and rolled up onto her back with her legs in the air.
"What in the world are you doing?" I asked
"I'm trying to help your little swimmers make it my eggs, so I can get pregnant". "Are you serious? You want to have my baby?"
"Of course I do, I think you'd be a great dad, and my baby and Kelly's baby can grow up together".
I wasn't sure what to think, but by this time, I knew it was out of my hands. If I wanted to prevent this from happening I should have used a condom, or simply had not fucked my sister at all. What was I thinking? How could I not fuck my sister when she was such a hot piece of ass, and was completely ready, willing and able to fuck me whenever I wanted it. I was living in a man's paradise, and was questioning my good fortune. I decided to just go with the flow, and told Sandra that I was tired and was heading back to bed.
"Don't worry about me, I'll be here for another 20 or 30 minutes. See you in the morning" she said as I left the bathroom.
When I got back to my room, Rachel was gone. Had she heard what had gone on in the bathroom? Had she heard what Sandra said about wanting to have my baby as well? I didn't know, and at this point I was so tired and so fucked out I couldn't have cared less. All I wanted to do at that moment was go to sleep, so I flopped onto my bed and immediately feel deep asleep.
When I finally woke up, the sun was pouring through the bedroom window, and Kelly was planting some small kisses on my face and neck. I yawned and stretched and pulled Kelly tight against my chest and kissed her full on the lips.
"Eww, yuck, you need to go brush your teeth" Kelly squealed as she pulled away from me.
"I mean it, go brush your teeth right now before you try kissing me again".
As I had a full bladder, and not wanting to piss off a pregnant woman I padded down the hall to the bathroom where only hours before I had fucked the shit out of my sister, and possibly impregnated her as well. I was trying to figure out who saw or heard what last night as I brushed my teeth and headed back to my room. As I walked through the door, I saw Kelly lying under the covers smiling up at me.
"Did you brush your teeth?" she asked
I nodded yes.
"Then come on over here and give me a proper kiss".
As I walked toward the bed, Kelly lifted up the edge of the blanket and I could see she was totally naked as I slid in next to her. For the next few minutes we kissed and cuddled, and I stroked her belly where my unborn child was now residing. The longer we kissed, the more erotic the kisses got and the more my penis began to fill with blood. I began to kiss and lick Kelly's neck, and then worked my way down her body, planting soft kisses on her collar bone, and shoulders, before moving down her chest to her breasts.
