My sister came home about an hour after my mother and I finished having sex for the second time that day. She changed clothes and we all sat around and chatted awhile, then Donna turned to me and asked if I wanted to go see a movie and have dinner with her tonight, just to catch up and leave Mom to rest in the apartment.
Mom was all for the idea so I put on some decent clothes and we left. I felt guilty because I didn't like lying to my girlfriend/mother, but of course I wasn't feeling so guilty that I wasn't filled with anticipation at finally getting to finish that lightning-charged moment Donna and I had had last night.
"Do you want to have dinner?" Donna asked as she drove. I could tell she was nervous.
"Sure, if you want to."
"Do you want to, like, go in someplace, or...like, a drive-thru?"
I grinned. "Drive-thru. It's faster."
She grinned back at me, and laughed. "My thoughts exactly."
So we went through a drive-thru restaurant, then my sister drove us to a hotel on the edge of town, just off the interstate, where I imagine most people who stayed there were just overnighters, on their way somewhere but had to stop driving for a few hours.
We got our food and checked in, I could see Donna's hands shaking as she signed the room invoice, and she dropped the key, twice, so finally I bent down to pick it up for her. She smiled shyly this time and she followed me to the elevator, and we went up to the fifth floor.
I opened the door to our room and we went in, then closed the door and engaged the two extra locks. She turned on a lamp and put her purse on the desk, then slipped out of her shoes and her jacket. I kicked off my shoes.
"Do you want your dinner?" I asked, holding up the bags of food.
She shook her head.
"Okay," I said, and put the food on the desk.
We stood looking at each other. "Well...what do we do now?" she whispered.
Curiously, as sexually active as I'd been all day, I got a sudden rush of shyness when looking into my sister's eyes just then and I'm pretty sure I blushed. "Well..." I said, clearing my throat. She was, after all, my older sister. "...what do you want to do?"
Then she blushed, too. "Well, I don't know about you, but I want to do what we came here for," she said, kind of half-smiling with her pretty lips, a familiar smirk that traditionally meant, knock off the bullshit.
"Me too," I said, and I smiled back at her.
"Come here, Bobby-baby-boy," she said, using the old nickname she'd used when I was little, which used to drive me into a rage.
I wasn't feeling rage now. I went over to her, close enough that her breasts pushed against my chest, and she looked up at me. "Kiss me," she said.
She leaned up on her tiptoes and I bent down and our lips touched. It was, as before, electric. The kiss grew in intensity and within seconds we were kissing passionately, suckling each other's tongues and moaning into each other's mouths.
She wrapped her arms around my neck and pulled me closer to her, I put my hands on her waist, then my hands slipped around to her back, then down and cupped her soft round ass. She moaned again as I touched her, and I felt her push herself against me. We stopped kissing for a moment, breathing heavily, looking into each other's eyes.
"It's okay if we do this, you know," she whispered.
"Yeah?"
"Uh huh. Did you see the card I filled out when we checked in?"
I shook my head no.
"We're registered as Mr. and Mrs. Robert Hemmings. I'm your wife, Donna Hemmings. I could even show my driver's license and PROVE IT." She saw my jaw drop, and giggled as she held up her left hand; it had a ring on the correct finger, which she wiggled, laughing. I hadn't noticed it before.
"So it's okay, see? A husband and a wife can check into a hotel room and in the privacy of their own room they can do... whatever they want to do, right?"
"Yeah, that's right."
She kissed me again. "So what do you want to do, Mr. Hemmings?"
"Well, um..." I swallowed.
"Go ahead, say it. SAY IT."
I swallowed again, or tried to, then I said, "Well...uh, Mrs. Hemmings... right now, what I want is for you to take your shirt off so I can look at you."
She wagged her finger in mock-anger. "Look at what, Mr. Hemmings? Be specific."
Despite myself, I blushed. "I, uh, I want to look at your beautiful tits."
"Okay, Mr. Hemmings, you wanna see my tits? Your wish is my command," she said, and pushed me backwards onto the bed. I sat on the edge and watched her pull her blouse over her head.
Her bra was pink and her breasts were crammed into it and crushed together, creating a deep wedge of cleavage. She reached behind her and quickly worked the hooks, then pulled the straps over her shoulders and shimmied the bra off, dropping it on the floor, revealing her naked tits. They glistened and I realized she was sweating a little in her nervousness.
They were teardrop-shaped, they hung low like Mom's but extremely firm, and the nipples were chewable pink buds with aureoles that weren't dark, just a slightly reddish-pink rash around the nipple, not like Mom's, which were dark brown and very lumpy.
My sister had a few tiny bumps around the nipple, but it was the nipple itself that drew the attention, set in the dead center of her low-slung breasts but pointed just a bit to the side. Perfect. Amazing. Beautiful.
"What d'you think of them?" she asked shyly.
Staring at them slack-jawed, I said, "I think...if I ever got my mouth on those things I'd never want to stop kissing them."
She blushed, and smiled, and said, "Who said you had to stop?"
And with that she moved forward and slipped her hands around the back of my head and pulled my face against her soft tits.
Again, they were quite different from our mother's tits, probably half as big, if even that--though still very, very big--and they were firmer, harder than our mother's, there was really no sagging to my sister's breasts, or stretch marks of any kind, or the blue and red veins that streaked across Mom's tits like a Rand McNally map... the skin was tight and unblemished and perfect, which of course was to be expected for a twenty-one year-old woman as opposed to a fifty-six year-old woman.
My sister's nipples were a true sight to behold, they were much bigger than Mom's nipples, especially as they grew erect when I wrapped my lips around one of them and used two fingers on the other one, they got bigger and longer and redder and harder, so big and long they almost seemed to be trying to separate themselves from her breasts.
I couldn't keep the differences out of my mind as I squeezed my sister's breasts and nibbled her nipples, moving back and forth between them while her fingers played with my hair and my ears... my sister had clearly inherited far-larger-than-average-size breasts from our mother, and their general shape was similar, they were round and low-hanging but attractive, not sloppy-looking, but that was about it, almost everything else was different. I loved both pairs, of course.
But I'd fantasized about my mother's breasts, loved her breasts from afar for so long, and now over the last two days had grown so used to them that I had to admit (to myself, silently, of course) that I found my mother's tits far preferable to Donna's, simply because my mother's breasts had more character, more miles on them, more personality, they drooped and sagged and had stretch marks and blemishes galore but they were MY MOTHER'S BREASTS and no mistaking them for anyone else's... whereas Donna's tits, while beautiful beyond measure, were so perfect that they could have been created in a laboratory given a billion dollars to create the perfect knockers.
They were that, they WERE perfect. But they could have been anybody's.
Was this a problem for me? I felt guilty right now to be sucking on the breasts of another woman when I was committed (and so recently committed) to my mother, but did I feel so guilty that I wanted to stop?
My cock told me no, let's not stop, and so I didn't. I chewed and licked and suckled and kissed and licked those perfect breasts and giant nipples and my sister moaned and her knees seemed to be shaking while I worked, and pretty soon the pain in my pelvis as my cock strained beyond what my underpants were willing to give, told me it was time.
I reached down and unbuttoned my pants and pulled the zipper down, giving some breathing space for the growing bulge of my underpants. I popped Donna's delicious cherry nipple out of my mouth and looked up at her.
Gasping for breath, she looked down at me between her own breasts. "Let's get in the bed or something," she huffed, holding on to me. "I think I'm about to fall over."
"Okay," I said, and scooted aside so she could climb into the bed.
Her tits swayed heavily as she moved across the mattress and then swung around on her knees and looked at me. She looked down at the prominent bulge of my white underpants pushing through the unzippered hole in my pants and she laughed, pointing at it.
