“What a guy,” I thought as I peeked back around the tree. Sis was sitting on the ground, naked, with her ass full of his cum.
After a couple of minutes, Sis reclined, drew her knees up to her breasts, and reached down to her spread cheeks. Sis then inserted her thumb into her freshly fucked ass and placed her forefinger, on her clit! Apparently, she hadn’t gotten off.
I knew the feeling. Sometimes after sex with a date, I couldn’t wait to get home, look at porn, and masturbate. I usually came a couple of more times, before I was satisfied. Cumming was so enjoyable!
All of a sudden, our eyes met. I heard Sis’s ass make an audible slurp from the quick withdrawal of her thumb as my hand tried to cover my cock.
An instant later, I decided to stop the charade. It knew it was now or never.
I unabashedly walked over to Sis and stood in front of her, gripping my hard cock. I smiled down at Sis and said, “I am sorry. I couldn’t help but watch the woman who gave me my first erection… I have never stopped fantasizing about you…”
After an eternity, Sis’s eyes softened and slowly dropped to my hard cock. Seconds later, her nipples hardened, again. Although I did promise myself never to forget this moment, it was not necessary.
My thoughts were interrupted, when I heard a voice from far away say, “Me, too.”
I refocused my eyes. Sis’s right hand, perhaps, subconsciously, was pulling on one of her erect nipples. Neither one of us had anything more to say at that moment.
I kneeled down in front of Sis and began to mount her, as she willingly leaned back and grabbed my cock. Sis’s hand guided me into the first hole she encountered. Neither Sis nor I cared which hole.
After pausing to allow Sis to accommodate me in her wet, tight hole, I began slowly stroking my cock in and out and back and forth. Soon, Sis was basking in the pleasure of being thoroughly sodomized.
When Sis began to lift her hips in response, I cupped her breasts with my hands to steady myself. Although the weight of her boobs surprised me, I began to accelerate my thrusting.
Suddenly, Sis sobbed and thrust her bottom down the entire length of my rigid cock, impaling herself. I felt her pussy contract hard and her rectum squeeze my cock like it was a fist.
Sis was cumming! Her face contorted and her sexy mouth widened into a perfect ‘O’ right before she began moaning, “Ooohhh. Ooohhh. Ooohhh.”
Moments later, as Sis’s petite body heaved and as
her pussy juice splashed against our thighs, a warm glow passed through me. I had just made Sis cum!
After Sis’s orgasms subsided, I freed my throbbing cock from her sucking rectum, and stroked it for a minute, as I stared at her glistening, slightly open, button-shaped anal ring. It was tantalizing – gaping open a half inch or so.
Having seen and paused long enough, I slowly pushed my swollen erection back into her. When I was in all the way, I began pumping away in her ass. It was mine now.
Sis’s eyes were barely open. She looked so vulnerable. I wondered if Dad and Stepmom had any idea how much of a slut their beautiful daughter was when they looked at her graduation picture. Knowing that Sis could act like a whore only turned me on more.
The only sounds Sis made now were short grunts as I butt-fucked her. When my lengthened thrusts bottomed out in her loosened rectum, I would pull my cock so far out of her that I would nearly pull it free of her gripping anal sphincter, before ramming it back in. It was glorious fun.
However, after a few more thrusts, it was my turn to start uncontrollable grunting. I adjusted my angle one last time and pushed my aching cock all the way up Sis’s relaxed rectum. I then grinded it hard into her a couple of times, before I hollered, “I’m cumming! Aaahhh. Aaahhh.”
I counted one, two, three spurts, before euphoria swept over me. My orgasm was mind-blowing.
When Sis felt my hot cum shooting into her rectum, she pushed her entire weight against my groin and wiggled her ass, encouraging my sperm to run deep into her bowels. I did not want that moment to ever end.
After I had finished unloading a week’s worth of stress deep inside my Sis’s rectum, she reached up and lovingly kissed my mouth. It felt good to be kissed like that, especially, after the ass-fucking I just gave her.
“Jeez! That was a huge fucking load! You gave a sperm enema little brother,” Sis murmured. I smiled in appreciation.
Being a woman of the world, Sis followed up her pronouncement by asking if I had completely emptied my balls. I just smiled and said, “Wait ’til dark.”
Sis then closed her eyes tight and grunted as her sphincter forced my gooey cockhead out of her dilated anus. When it popped out, I kissed Sis on the cheek and then started to help her up. However, when she saw my semi-hard cock leaking a little cum, she opened her mouth.
The way Sis’s full lips wrapped around my soiled, swollen cockhead almost made me sorry, I had ejaculated all my sperm into her hot ass. As it was, Sis did nurse a couple of drops out as she greedily sucked my cock clean.
When Sis finally let go of my cock, I wistfully pulled my shorts back up and I looked over at her. She had not moved.
Sis gave me a pained look and then rubbed her tummy. I walked away to give her a little privacy.
Although Sis tried lady-like, there was no graceful way to shit all of the cum out of her bowels. Finally, she just closed her eyes and with her face fixed in concentration, grunted hard and loud, forcing the conglomeration of sperm out her ass.
As squishy fart sounds erupted out of Sis’s beautiful ass; the ass that I lusted after and had just fucked, I tried to think about the weather. That didn’t work.
After Sis was through, she remained in her squat. She had the, “Whoops, I just ate the canary,” look on her face.
This time it took me a couple of seconds to figure her look out. When I did, I walked up to her, and handed her some old tissues that I had in my pocket.
Despite our attempts to clean-up, we both smelled like sex – anal sex. Sis’s breath wasn’t that great either.
Before heading back up the road and to our grandparent’s house, Sis and I leaned against each other, kissing and whispering about how great it would be if we could go to bed together every night and have each other all night long – forever. Yes, Sis and I had officially fallen for each other.
Sis also confided that when she knew I was up late, she would get down on all fours, crawl to my bedroom door, and look through the key hole.
Sis laughed, saying her mission was to catch me lying on my side, jerking off as I watched porn.
I learned many more things about Sis that day. For example, Sis could cum from breast stimulation alone! Sis also confided that that was the first time she enjoyed anal sex.
I reciprocated and described her role in my wet dreams. Boy, did she ask questions about that!
The rest of the holiday passed in a blur. Sis and I fucked each other silly whenever we could get away or be alone in the house.
Our favorite place was on the deserted beach, at night. We loved to hear the breaking waves as we made love.
Sis liked to stretch out on a beach towel, naked from the waist down, with her legs hoisted over my shoulders. She loved having me eat her delicious pussy and lick her sweet anus as she stared into the night sky, observing the twinkling stars.
After Sis was satiated, she would get into my favorite position – prone. I liked it when she spread her cheeks, so that I could slowly work my hard cock into whatever hole she had chosen, inch by beautiful inch.
Sis is all I ever wanted.
