I'm in love with my sister, and I have been for some time. Jenny is five-six, weighs about 115 pounds, is perfectly proportioned at 36-24-36, has waist-length curly black hair, a dark tan, and the most remarkably beautiful ice-green eyes I have ever seen, but that's not why I am in love with her. Well, at least, not the only reason. She is the kindest, sweetest, most caring person I have ever known, and not just toward me, either, but anyone and everyone she meets. She also has a voluptuous ass I just want to sink my teeth into.
I wish I had the courage to take a chance and see where it goes, but I really don't want to get my feelings hurt. Oh, sure, she might get angry if she knew, especially considering how many times we have stood naked in front of each other. Did I forget to mention that I am female as well? I am Jenny's younger sister by eighteen months. Now you see my dilemma.
In contrast to my sister, I am five-eight, same 115 pounds, but 34-24-34, and my ass isn't bad, truth be known. I have straight, shoulder-length dark brown hair, a decent tan of my own, and my eyes are blue. I consider myself an attractive woman. I mean, I may wear glasses and be a bit nerdy, and judging by the number of guys who ask me out and all, I must be pretty good looking, but I'm a lesbian. Still in the closet, I hate to say, but I just haven't found the right time or way to tell everyone.
I think of the relationships I can have with other women, but I obsess over my sister too much. I want her so terribly that it hurts, yet I can never tell her. I am sure opportunity will present itself one day, and when it does I plan to take full advantage of it.
Jenny respects my endless pursuit of knowledge. Sometimes she calls me "The Encyclopedia of Useless Information," but if she ever needs to know something, I'm her go-to gal. One particular day, as I was sitting on the sofa reading the current issue of
Popular Mechanics
—yes,
Popular Mechanics
—she plopped down next to me with a disgruntled look on her face. "What's wrong?" I asked without the benefit of looking up.
"I'm constipated," Jenny told me. "I haven't had a bowel movement in two days. Look at my belly. I'm bloated."
Face still snugly imbedded in the magazine, I asked, "Been eating a lot of starches lately?"
"Tots for breakfast and fries for lunch and dinner every day this week."
"How's your water intake?"
"Not what it should be," Jenny answered.
I reached out and felt just below her tummy. "Yep. I can feel it."
"What should I do?" Jenny asked.
"Take some Ex-Lax," I suggested.
"You know Aunt Peggy was addicted to laxatives," she reminded me. "I don't want to chance ending up like her."
"Tall glass of prune juice, then," I offered.
"You know I hate prunes. The juice is even worse."
I finally looked at her. "Enema?"
"I suppose so," Jenny reluctantly said, "although I hear those can become addictive as well."
"If you do them every day, yes," I informed her, "but one here and there? You should be safe."
She patted my leg twice and said, "Thanks, Sam," then made to go upstairs, and that's when the brain child was born.
"You know," I called out to her, "there is another method, if you're interested in hearing it."
"What?" She asked as she turned and walked back toward me.
"In certain villages in Botswana, the people orally stimulate the anuses of their livestock," I reported. "They do this because they believe it helps the animal have more frequent bowel movements, which, in turn, they believe makes the females produce more milk and makes the males work harder."
"You're telling me that the people of Botswana eat their cows and bulls asses?" Jenny asked before a wave of laughter came over her.
"They've been doing it for hundreds of years," I said straight-facedly, simply because it was true. The things one can learn from reading
National Geographic
. "You know anyone who would do that for you?"
"Not really," Jenny answered. "Josh and I broke up last week, as you know, so I won't be asking him. It wouldn't be fair to ask another guy because he might think it'll lead to sex, which I don't want to happen. I doubt my girlfriends would do it simply because they might think I'm trying to lez out with them." She remained silent for all of thirty seconds, then said, "How about you?"
"Me?" I sounded so surprised by her invitation.
"Sure. Why not? Aren't you always looking to test one theory or another?" she reasoned. "This would be the perfect opportunity for you. I can see it now: 'Does stimulating a person's anus make him or her more apt to have a bowel movement much the way bovines do when anally stimulated in Botswana?' What do you say?"
I sighed heavily, then said, "In order for me to test the theorem, I would have to conduct the same test over a week-long period. Would you agree to that?"
"Yeah, sure," Jenny said enthusiastically. "Whatever gets me to pooping."
I didn't tell her that I would have to test her results against those of others, simply because there weren't going to be any others. I nodded my head as I reached for my laptop. "Okay then, go on upstairs and take a shower, and clean yourself well. I'm going to research this some more and see if there is a particular methodology I should apply."
"Right!" Jenny said as she ran upstairs. I closed my laptop, and once I heard the bathroom door shut I stealthily made my way upstairs to Mom and Dad's room, into their bathroom, where I opened the medicine chest. Right out front were Mom's laxative suppositories. I grabbed one and placed it in my pocket. I honestly did not know if eating an ass would make someone poo, but I had to ensure that she did in order to milk it over the remainder of the week.
I went back downstairs and awaited Jenny's signal, and about fifteen minutes later she called down to me, "Okay, I'm all done up here."
With a heart beating like a jackhammer, I happily made my way upstairs and to her room to find her standing next to her bed wearing a towel. I sat at the edge of her bed and said, "From what I could tell, it's pretty much like just getting a rim job. Have you ever had one of those before?"
"No," she answered as she lightly shook her head.
And I'm going to give you your first one
, I thought, and immediately I felt myself get wet. "Okay then, here's what you can expect: I am going to begin by slowly licking around your anus, then I will lick the anus itself. From there, I will graduate to sucking it, lightly at first, then a bit more aggressively. Toward the end, I will insert my pinkie into it. Not all the way, just enough to stretch it a little. All in all, it should take about twenty minutes. Any questions?"
"Not really, Sam. Just that I know I kind of goaded you into this. You don't have to do it if you don't want to."
"Hey, like you said: All for the sake of science, right?"
Jenny smiled. "Right. Now ... Um ... How do you want me?"
"Remove the towel, hop on the bed, hands and knees," I instructed her, and she did so.
Oh, her ass was so gloriously plump and round. Firm yet fleshy would describe it best. I wanted so badly to kiss each perfectly tanned cheek, but I couldn't give myself away. "Are you ready?" I asked. She said she was, so I placed my hands on her rump and separated the cheeks, and there was her asshole, almost as tanned as the rest of her, staring me in the face. I slowly moved toward it, stuck out my tongue, and licked the side of her anus. Then, "UNH!!"
"What's wrong?" Jenny asked as she looked back at me.
"Nothing-nothing," I said quickly. "I was trying to contain a sneeze is all." Not the best lie I had ever told, but she didn't need to know that I had just had an orgasm. I repositioned myself, then began the process anew. I licked the left side of her anus very slowly, then the right. I actually began by dividing each lick, but soon I was moving my tongue in the motion of a capital U, and I was enjoying every second of it.
