The vacation of a lifetime was coming to an end. Elaine and I had done the tourist thing for nearly two weeks, and between that and our nighttime activities, we were ready to return home soon. Neither one of us looked forward to the long travel, but it would be good to sleep in our own beds.

Of course, the caveat was that we would no longer be sleeping together. As my half sister kept reminding me, it has been a wonderful ride, but we need to take a break. Since arriving in London to see our father and his chesty bride, we had been screwing every night, experimenting with a variety of positions and techniques. I discovered that my sister loved cunnilingus, especially when I explored her nether regions with my tongue and fingers. We had even tried fitting my cock in her little bunghole, but her discomfort with my size soon persuaded us to stick to more conventional forms of sex.

Elaine's inexperience before she discovered me was soon remedied. She was an ardent student of sex, always imploring me to instruct her as to my desires. There was little she wouldn't do to make me happy, anal sex being a notable exception. Not that she wouldn't do it if pressured, but it was not that important to me, so we avoided it, at least using my cock.

We had seen all the major tourist attractions, and so with only a few days left, Dad suggested that we experience a throwback to old times: "high tea."

Elaine was excited about it, but I deferred.

"I think I'll take the day off and maybe read," I explained. I'm ready for a break. Sipping tea out of fancy cups didn't particularly excite me.

Julie, my dad's "new" wife, concurred. "A day off sounds good. We'll replenish our energy for a last sprint before you leave."

So with our assurances that we'd be fine, Elaine and her father left us for the day.

Elaine and I had used the rental flat only for sleeping, not to mention our late-night sexual romps, but during the day, we hung out in our father's nicer apartment. Once he and my sister were gone, Julie asked if I needed anything.

"I'm going to lie down for a spell, Ron. Make yourself at home. If you need anything, just holler. You know where everything is. Help yourself to a beer from the fridge if you'd like. Whatever you want. I'll leave the door open so I can hear you if you need anything."

I made myself comfortable in their expensive Danish recliner and opened my book. Soon the coffee was working, and I got up to empty my bladder. As I passed Julie's bedroom, I glanced in and saw that she was apparently sleeping. She was lying on her back in a silky robe that was half open, and her large boobs were on display in a huge white bra. I stood there for several seconds gazing at those mounds of joy before moving on to pee. I left the bathroom door open, a bad habit of mine, and watched as a heavy stream drilled the toilet bowl. I closed my eyes and imagined my cock nestled between those big boobs of Julie's when I heard a cough.

I looked up to see her standing there with her hand to her mouth and a look of shock on her face.

"Oh my god, Ron! Sorry. I got up to use the loo and didn't realize you were in there since the door was open." She was obviously embarrassed, but she didn't look away as I hurriedly shook my fleshy appendage and stuffed it back into my pants. I smiled a guilty smile and shuffled past her as I made my way back to the main room.

"The loo is all yours. Sorry about that. I should have shut the door. I think I'll head back to our flat and maybe take a nap."

"Oh, no worries, Sweetie. I've seen lots of penises before today." She giggled. "You look like your father, only bigger." She giggled again and turned beet-red. "Oh my gosh, Honey, I can't believe I said that."

I smiled and excused myself. Dad's new wife seemed to have a playfully raunchy side to her that I hadn't noticed before.

"Have a nice nap, Ron. I'm here if you need anything at all."

I walked down the hall to our flat and lay down on the sleeper. We had left it pulled out from the previous evening, and I tried reading, but soon found myself dozing. I dreamed that I was in bed with Elaine and looked over to find Julie on the other side of me with my cock in her mouth. She was gagging and laughing about me being too big for a snack when suddenly, she jumped up at the sound of a door knock.

"Oh, shit. It's your father."

That's when I woke up to a real knock on the door. I rubbed my eyes and got up to answer. That's when I heard Julie's familiar voice.

"Ron, sorry to bother you. Are you in there?"

I opened the door and there she stood, an open bottle of champagne in one hand and two flutes in the other. She had changed into a tight-fitting sweater that accentuated those big boobs of hers. But then I realized she must be wearing a fifties-style bullet bra from the looks of her pointy tits. Her headlights were burning brightly. Her blue eyes sparkled. She looked like the early Madonna on steroids.

"I decided to have a late morning glass of champagne, but I hate drinking alone. Would you be so kind as to join me for a little glass or two of bubbly?"

She stood there awkwardly, both hands full, and nodded her head as if to ask, "Okay to come inside?"

"Oh, sorry. Sure. Come on in. Have a seat. Let me take those from you."

I grabbed the glasses and, instead of going to the kitchen table, she sat on the edge of the sleeper.

"Sorry if I interrupted your nap. Come sit by me and bring those glasses. I started without you, but thought, 'This is the perfect opportunity to get to know Ron better.' You are my stepson, sort of."

I sat next to her as directed, and she poured the wine into the flutes.

"You must be a light sleeper. Your bed hardly looks like it's been slept in. Or is Elaine sleeping here?"

I almost bit my tongue when I first thought she was implying we were sleeping together.

"No, this is my bed. Yeah, I guess I'm a neat sleeper. I meant to fold the bed up, but didn't get that far."

"No worries, Ron. It's comfy. Maybe it will come in handy later. Let's toast. To you and Elaine for your wonderful visit. Both your father and I are so happy you are here, but especially me. We don't often have such lovely young people around us."

I wondered about her comment that the bed might come in handy, but ended up making small talk through another glass or two. And then the bottle was empty, and we were both a little giggly.

As we sat there, Julie touched me lightly and laughed at everything I said as if I were the most interesting person on earth. Suddenly, out of nowhere, she leaned over and kissed me lightly. She burped and giggled.

"Forgive me. I just had to kiss you, you are so much fun. And handsome. The wine has made me a little dizzy, I guess."

Then she lay back on the bed, her arms thrown over her head and her breasts sticking straight up like two huge, inverted ice cream cones.

I couldn't help but stare at them.

"They're big, aren't they. I call them boy magnets. Your father couldn't wait to get me naked so he could play with them. He's a randy old goat at times. And I notice you checking them out, too, you little bugger. Come here. Give your stepmom a little kiss. I'm old but not too old. I bet you'd like to play with them as well, wouldn't you? Well, if you're nice, maybe I will.

Julie grabbed my arm with surprising strength and pulled me on top of her. My momentary resistance did not slow her down, and a playful peck soon became an open-mouthed French kiss. Julie's tongue found mine, and I found myself between her legs, and her hips grinding into mine. My hand found a firm tit and I squeezed it as if to see if it was real. It was.

"Yes, Sweetie. Go ahead and feel my big boobies. They're yours if you want them. I bet you'd like to suck on them, wouldn't you?"

Julie rolled me over and straddled me.

"There, this is better."

Smiling, she pulled her sweater over her head and sat atop me with her breasts swelling in the large, pointy cups of her bra.

"Do you like this bra? Your dad is crazy over these outdated undergarments. Thank god they have strong straps. These puppies are heavy. Or, wait! Would you rather I take it off?"

As hot as she looked with those huge tits stuffed into a shiny white bra, I couldn't wait to see them bare.

I didn't wait for an answer. I reached up behind her and unfastened the hooks. Julie lowered the shoulder straps and slowly inched the bra away from her advancing cleavage until her huge nipples came into sight. She threw the bra aside.

"Ta da! And there they are. Your prize for the day. What do you think? Worth the risk?"

"Julie, this is crazy. Elaine and Dad could come in at any second."

"No worries, Honey. They'll be gone all afternoon, but even so, doesn't that make it more exciting? Hmmm? The fact that we could get caught in coitus? Or do you call it fucking? Oh, wait. We haven't done that...yet. When I saw your big penis a while ago, I knew I had to have it. We'll need to get these pants off so I can see that snake up close."

Julie was a woman on a mission. The demure, upright British lady had moved over for a wanton harlot. We were both living in the moment. She had become a ravenous man-eater. She fed me a fat nipple to suckle for a few moments, and then scooted down to get my pants off.

Julie deftly undid my belt and unzipped my fly. She reached in and pulled out my rapidly growing cock. In seconds, she had my pants off me, and my cock dwarfed her small hand. With a brief introduction of what she wanted to do, I was soon covered with saliva, and her brightly painted lips were wrapped around my thick shaft.

"Oh, Honey. You have such a beautiful penis. And you taste so good."

Julie commenced fellating me like a seasoned veteran. Her long tongue swirled around the head in wet circles, and several times she almost had my entire length in her throat. Her eyes looked up at me periodically to watch my rapturous face. After several minutes of sucking my cock, she came up for air.

"Should we see if you will fit in another place? I bet you never thought your step-mother was so horny, did you? Wouldn't you like to stuff this in me?"

I needed little persuasion. She released me to remove her slacks and panties and then regained her position atop me with my eight-inch missile aimed directly at her untrimmed pussy.

"Hope you like them natural. Your father says it goes with the old-fashioned bras. Wow, you are big. Not sure this sausage will fit, but I'm willing to die trying."

She sluiced my helmet back and forth between the lips of her hairy jungle, and then suddenly I felt it gain purchase and enter that moist passage.

"And there you are. In Momma's pussy. How does that feel? I feel like I just sat on a salami. Whew! You're taking my breath away. Honey. I don't think I've had one this big before. Does my pussy feel good? You are definitely a tight fit. We need to start slowly until I get used to you."

Julie leaned over and dangled her tits in my face as she began humping my cock with her fleshy ass, gradually taking in more and more of me. I gripped her hips with both hands as we fucked. She was a few pounds overweight, most of it in her buttocks and thighs, not to mention her breasts, but her skin was smooth and soft. Her nipples were like none I'd ever seen. The areolae were the size of small plates with large nubs to match. I sucked on a ripe nipple, and Julie smiled.

"That's it, Baby. Suck on Momma's big titties. I love that. Oof! You are so deep. I'm a virgin there. You are in uncharted territory, Captain. God, I'm soaking already. I have to warn you. I sometimes squirt, and I have a feeling this is going to be one of those times."

She leaned over me and kissed and hugged me. She was surprisingly agile for a forty-something MILF. As our tempo increased, she licked my ear with her slithering tongue and guided me with breathy whispers.

"That's it, Baby. Fuck me nice and deep. God, I haven't been shagged like this in ages. I've got a real man's prick inside me, don't I? Your willy is so thick, Honey. You're scratching all my itches. Do you like the way my pussy slides up and down? I'm getting close, Honey. I have a special request. I hope you are not offended."

My brain was on fire, and I was struggling to keep from cumming. She was alternately kissing me passionately and whispering hoarsely in my ear as if it were a secret.

"Sure. What is it?" I couldn't imagine anything better than what I was feeling.

"Will you fuck me in the ass? I love that, but your father thinks it's dirty. I'm clean there, I swear. I want to feel this big snake in my ass. Will you do that? It would make me so happy."

I felt her tongue once again sensuously circling my ear as I nodded approval. Julie raised her ass, and I grabbed the shaft of my cock. I slid it back and forth between her butt cheeks with no luck. Finally, Julie grabbed me and found her sweet spot and managed to get just the head in.

"There you are, Sweetie. Oh, fuck, you feel good. Nice and slow. This is going to put me over the top."

I gradually worked myself deeper and deeper until I was buried. Julie was sitting upright with her hands clasped behind her head, making her tits defy gravity and jiggle wantonly. As if I had pressed a button, she began a series of jerks, and suddenly I felt a flood of pussy juice squirting on my groin.

"Oh, oh, oh. I'm cumming, Baby. That's it. Fuck me just like that."

That was it. I reached up and grabbed her tits, squeezing them as I shot off like a cannon in her ass. We both came at the same time.

Julie muffled a scream as wave after wave took over her lower torso. As it slowed, she crushed her mouth into mine and kissed me until her orgasm finally stopped. She raised her ass and craned her neck to watch as my cock slipped out of her, followed by a stream of milky goo. We both lay there for several minutes without speaking.

Finally, Julie rolled off of me and began dressing. I closed my eyes and smiled.

"Sweetie, I can't remember the last time I enjoyed anything close to that. You have fucked me like I needed to be. I'm going to hate to see you leave. Don't be surprised if you get free tickets in the future. You have made an old lady very happy. I hope you liked it as much as I did."

She kissed me a few times, and I dressed and tried to straighten the bed. A huge wet spot remained where I had been lying. I closed up the sleeper and escorted Julie to the door. We kissed there, and I said I'd be down at her apartment soon. She squeezed my cock through my pants and gave me a final kiss.

By the time Elaine and Dad returned, we were back to normal. The bullet bra and tight sweater had been replaced by frumpy house clothes. We heard all about the tea, and later that night, I convinced my sister that for one night, we could leave the sleeper folded up. We didn't have sex that night, but only cuddled. If Elaine thought something was amiss, she didn't say anything.

The following days went by quickly, and we were soon on our way home at thirty thousand feet.

"A penny for your thoughts." Elaine wondered why I was so pensive.

"Weird! I was just thinking about those old-fashioned bras from the fifties. You know. They made women's tits look like Saturn rockets. I think they should bring them back. Want to start a new fashion trend?"

"What on earth brought that up? My brother is one weird guy. Would you like me to buy one and pose for you, weirdo?"

"Actually, I'd like that very much."
