Once back home from England, we had to rearrange our priorities. As much as I loved fucking my little sister for the past two weeks, our home in the US was just small enough that Mom would easily discover our secret, so we decided to cool it for a while. Nightly bouts of consensual sex with her had spoiled me, and on top of that, I had a wild fuck session with my new British "step" mom, even though we barely knew one another.

I had not told Elaine about that tryst since I was unsure how she would take it. Eventually, I hinted about what had happened, and, to my surprise, she already knew about it.

"That's old news, Ron. I figured something had happened when Dad and I went out that afternoon. I checked out the sheets on the pull-out bed when you were out walking, and your tracks were all over it. Plus, her lingering perfume was obvious. Julie was not quite as straight-laced as she put on. She loved to flaunt those big, pointy boobs, and you didn't seem to mind. So, how was she?"

"I explained as best I could that she had seduced me, and that I had tried to resist. I didn't bother to tell her that I came in her ass and she loved it."

"No worries, Bro. As I told you, this is a neutral arrangement: no-guilt sex. As long as we keep it that way, it's no harm, no foul."

"Thanks for being such a wonderful sister. I really didn't initiate sex with Julie, but I didn't resist too hard, so to speak."

"And speaking of hard, Mom's gone to work and we have the house to ourselves for a change. Let's go into my bedroom, and you can show me that fat cock of yours. All this talk is making me horny. I haven't been screwed in over a week, and I'm going through big-penis withdrawals. But I know where I can find relief."

She stood on her tiptoes and kissed me lightly. At the same time, her hand found my cock through my shorts, and she rubbed along its length.

"Hmmm, what's this? Whatever it is, it's hard. And big! Just what the doctor ordered. It so happens I showered and shaved this morning. Would you like to see? I'm bare as a baby's butt down there now. No "pubies" to have to spit out."

I followed her into her bedroom. It was still decorated with posters of dated rock stars from her early teen years. She closed the door behind us and pulled me to her.

"Let's get some of these clothes out of the way. I'm going to leave my bra on as a teaser, but wait til you see my new look. I think you'll like it."

In minutes, Elaine was on her bed wearing only a stuffed bra. Her vagina was indeed freshly shaved, and her large labia and clitoris were prominently displayed. She reached down and rubbed her clit and then spread her labia with two fingers before dipping one inside her pussy.

As I kneeled between her legs, she placed her moist finger in my mouth.

"Have a taste. Fresh pussy, just the way you like it."

She spread her legs wide with her feet in the air and motioned me closer with her finger. My lips started with her inner thighs and worked slowly toward her honey-sweet cunt where they found her swollen sex. Already, she was wet, and I slipped my tongue briefly inside her.

"God, I love your tongue almost as much as your cock. Can you taste how wet I am, and we just got started? Mmmm, yes! Just like that. Did you eat Julie before you fucked her, you bad boy? I bet she sucked your cock, didn't she? What would Dad say if he knew his son was fucking his wife? God, I get hot just thinking about you pounding her. I thought she was walking stiffly there for a while. Oh, fuck. That feels so good. Go ahead, yeah, like that. Put your tongue in my ass just a little way. That is so nasty, Ron. But I love it."

I was too busy eating to talk, so Elaine kept it up for both of us between moans and occasional giggles. She had both hands wrapped around my head and pressed me into her sweet cunt, rolling her hips and craning her neck to watch. We continued like this for at least ten minutes, if not longer. I began using my fingers in conjunction with my tongue, and soon the talking stopped and the moaning increased.

Finally, I could tell she was getting close, and her hips began bucking and shaking until her whole body stiffened and she gripped my head in her muscular thighs. A guttural grunt followed by a semi-stifled howl came from my little sister as I wormed a finger in her ass and reached as deeply as possible in her other orifice with my tongue. A stream of pussy juice shot into my mouth and all over my face. Elaine's lithe body jerked in rigid spasms of pleasure for several seconds before finally relaxing. She struggled to regain her breath.

We stayed like that for a bit before I felt her pull me up so she could kiss me.

"Come here, you beast! God, I needed that. And look at you. Your face is shiny with my juice. You look like a glazed donut."

We kissed, and she tenderly licked me clean.

I rolled over and lay next to her, caressing her bra-covered breasts and kissing her face and ear. I had previously removed my shorts and underwear, and my cock lay semi-limp against my thigh. Elaine reached down and slowly stroked me until I was rigid and at attention.

"You want a blow job or just get right to it. Your choice."

Without saying anything, I rolled her over on top of me, my cock trapped behind and between her butt cheeks. I reached up and unfastened her bra, releasing those perfect mounds capped with dollar-sized puffy nipples."

"You do love my tits, don't you. They're not as big as Julie's, but give them time."

She leaned over and dangled a fat nipple in my face for me to suck on, which I did. At the same time, Elaine reached behind her and, gripping my cock in her small hand, raised her ass and rubbed the helmet back and forth between her labia.

"No need for Astroglide today. I'm lubed and ready to fuck. Just go easy on me to start. It's been some time since I've ridden this bruiser. I need to get stretched out even after the tongue lashing you just gave me."

I felt her slowly settle on my cock until, gradually, in longer and longer strokes, she took in more and more of me. Finally, I felt her bubble butt come in contact with my thighs. I was home once again.

"Jesus, I've forgotten how huge you are. It feels like you are in my throat, or at least my stomach. Let's just fuck nice and slow for a spell. Is this as good as Julie? I bet you loved having those big torpedoes bouncing on your chest. She showed me her breasts. God, her nipples are huge. Dad must be a tit man. Mom's got some hooters as well, hasn't she? Oh, fuck. Yeah, just like that. I love your big cock stuffing me. Am I tight enough for you? I bet I'm tighter than Julie."

I only smiled. I knew she wanted me to say something about fucking our stepmother, but I didn't take the bait. I only smiled and kissed her or sucked on a ripe nipple as we fucked in unison. Elaine used her flexibility to twerk her ass in tight circles or hump me back and forth, as well as up and down. Occasionally, she leaned back, her hands clasped behind her head, her breasts jutting, and then placed my hands on her firm mounds.

I love it when you play with my tits while we fuck, Ron. Go ahead and pull on my nipples. Yeah, like that. They're not as big as Julie's, but they are still pretty large, aren't they?"

"Your tits are wonderful, Elaine. You are a dream come true. I'd rather fuck you than Julie, any day."

That brought a smile to her face.

"Oh, that's so sweet. And just for that, I'm going to make you cum, but I want you to cum in my mouth. Let me know when you are getting close. I want to taste you."

With a devilish smile, Elaine doubled her efforts, kissing me passionately as her ass humped and gyrated on me, squeezing me tightly with her pussy muscles. And it didn't take long. As I squeezed and pulled on her jiggling breasts, I felt a familiar surge of sperm trying to escape from my balls.

Elaine sensed it as well, and she jumped off of me and replaced her cunt with her mouth. Jerking me forcefully, she sucked so hard her cheeks hollowed, and that was it. Her mouth was obscenely stretched over my glans as the first squirts shot out the end of my throbbing cock.

"Oh, fuck. I'm cumming~"

A thick stream of creamy white goo shot in her mouth to overflowing until she could not contain all of it. Swallowing and choking, she did her best to keep up, but the volume was too much. Cum dribbled down her hand and onto my thighs. Not to be outdone, she swallowed what was in her mouth and, once she had regained her breath, scooped up what she could with her fingers. When she was satisfied, she had cleaned up the overflow, she leaned up and kissed me.

"Wow. You've been saving up. That was quite a wad, there, Bro. I think you just spoiled my dinner. I'm stuffed: literally and figuratively. Thanks. You made my day."

We lay there for a bit before getting up and doing our best to hide any evidence of our joint venture. When Mom came home after work, we were watching television and snacking on Cheetos.

"How was your day, kids? Do anything fun?"

"Yeah, Ron and I had sex, Mom. How was your day?"

I nearly choked on a Cheeto and turned my head away in a panic.

"Oh, Elaine! You know how inappropriate it is to joke like that with your mother. That's not even funny. And look, you've embarrassed your brother. He's going to choke to death."

"Sorry. No, we had a pretty normal, boring day. Life back at home and all that after international travel."

"Well, maybe we can all do something together tomorrow. We can celebrate the weekend."

"Sure. Sounds like fun. Just the three of us. What do you think, Ron? Ready for some fun with two randy women?"

"Elaine! I may be middle-aged, but I do know what "randy" means. I'm not that old." She pulled her shoulders back into an erect posture as if to take a few years off her middle-aged body. Her heavy breasts responded by rising and jutting with her gesture. Her nipples were clearly visible.

I looked up and realized that, yeah, Mom really does have some nice tits. Dad had good taste. Suddenly, the picture of my mother and sister naked and sharing my cock popped into my head. I tried to think of something else, but as of late, my fantasies were coming true. The image remained, and I put a pillow over my lap.

"Yeah, who knows? Could be fun. I'm game for anything."
