Desc: Erotica Sex Story: Chapter 1: Little Sister - My housekeeper asked if her little sister could come to stay with her in my house for a while. I said yes. The little sister really liked spending time on the rooftop. Complications ensued.

I WALKED UP behind her, behind the low wall where she rested her elbows to steady the binoculars. I know she heard me but she didn’t turn. I looked up at the apartment building across the street. Her target, the nude figure standing in the window opposite us, apparently fresh from her shower with her hair wrapped in a towel, was easy to spot.

I leaned in close to whisper in her ear.

“You’re a bad girl, Roberta.”

No reply. I rested my hands on her shoulders, colored a light peach from the sun, and kissed the back of her neck. She smelled of sweaty girl with an overlay of sunblock and a gentle touch of shampoo. I moved my fingers in little circles, her skin smoother than the smoothest silk and without blemish.

“A very bad girl.”

I think I heard a giggle this time, but still she didn’t turn, didn’t put down the binoculars.

With my fingernails I drew lines down her bare smooth back. She’d skipped her t-shirt this afternoon.

“A very very bad girl.”

Now I was certain I heard a giggle. I repeated the strokes a couple of times before I touched her flanks lightly to stroke her again, only this time I moved up and around to her almost-flat chest, perhaps the most prominent sign that even if she’d come of age more than a year ago her body hadn’t caught up yet. She shivered when I very lightly dragged my fingernails across each erect nipple, the silk of her skin yielding to slightly pebbled areolas and then to stiff little bumps.


“Really bad,” I whispered as I turned my hands over and let the pads of my forefingers pass with the lightest of touches over each nipple and up to stroke the sides of her neck. I kissed the back of her neck again and each side.

“Yes,” she dragged out the word and turned it into a sibilant whisper. At the same time she widened her stance and moved back but I shifted to stand beside her. I wasn’t going to give her the pleasure of that contact. Yet.

“Aren’t you worried she’s going to notice you, Roberta?”

At last she lowered the binoculars and turned to look at me. She shrugged.

“I don’t care.”

Another giggle.

“Besides, she’s the one in front of the window, right? I’m standing on my own azotea minding my own business.”

Aside from the minding her own business bit and that it was my azotea, not hers, she had a point. If the neighbor wanted to display herself she could hardly complain if others noticed.

Roberta let the binoculars rest against her chest.

“What are you doing home so early, don Alejandro?”

Cheeky, it was my house and Roberta was here as a favor to her big sister, my housekeeper.

“Checking on you, querida.

I’d known for some time what the pint-sized minx was up to but wanted to confirm it. Showing up when your household staff doesn’t expect you is sometimes very enlightening. My colleague James told me he’d arrived home once unexpectedly during the siesta, a custom not observed by most businesspeople in this capital city, to find a mini-orgy going on in his living room. What made it pretty funny was seeing the three or four members of the little Bible study group his cook had organized and hosted, with his permission, for a couple of years by then, in a tangle of nude bodies on the rug.

There wasn’t any doubt who was in charge. Marta, the cook, stood as tall as her four feet eleven inches would let her over the group, her legs apart, her pubic curls thick and wet and tangled. Her full breasts, nipples extended, were spattered with what looked like semen. She had a stiff brush in her hand and at least two of the visible bottoms, male and female, were red and marked, James said. I wondered if he’d joined them but if so he didn’t share that part of the story with me.

Plus, and I’ll just lay this out right now, I had other thoughts, ones I was pretending to stay away from, but I’d decided where I was going and the only real question was how long it would take to get there and how many twists and turns the road might have. Two, or even three, could dance this dance. My housekeeper was a worthy foe, and her little sister a quick and enthusiastic study.


“And what, Roberta?”

“You know what I mean. Is it OK?”

I shrugged.

“If she gets ticked off and does something about it, sweetie, it’s all on you.”

A snicker.

“Yeah. That’ll be the day.”

I wondered if she’d seen the movie. Probably not, although everyone around here seemed to know who John Wayne was.

“Are you going to get in the water, don Alejandro?”

“I think so.”

“May I join you?”

She knew the answer. I’d long ago given her and her sister permission to use the hot tub in a corner of the roof whenever they wished. Its lattice screen on two sides and large plants in pots all around gave it some privacy, although perhaps less than we might have liked during the day, especially from those on the upper floors of the high-rise Roberta liked to inspect with her binoculars. I had a feeling there might be more than one person up there with his or her own pair of glasses, perhaps including the present target of Roberta’s surveillance. She may not have been nude but, boyish figure or not, she was topless.

“Of course, Roberta. You know that.”


She put the binoculars on the bench beside her and skipped over to the hot tub, stripped off her shorts and hopped into the water wearing only her panties. I went downstairs to my bedroom and changed into my swimsuit. Nude was better, except not this afternoon, not alone with this frisky little person who had clearly learned more than was good for her from observing her sister.

I had yet to yield to her sister, even if this wasn’t the first time I’d used my fingernails on Roberta and Sara knew it. I was pretty sure my fingernails weren’t the first ones to drag across her smooth skin and the little bumps that soon would adorn real breasts, either. So far I was confident there were no unannounced visitors when I wasn’t home, but the looks and giggles and snatches of conversation I overheard, especially when the two returned from a weekend visiting their parents and siblings in that cow town up north, suggested Roberta was learning fast and enjoying each discovery.

I’d drifted off into a doze thinking about the two of them when something wet hit me in the chest. I opened my eyes to see the minx grinning from the other side of the hot tub. I looked down. Her panties floated in the water between my legs.

“Gotcha, don Alejandro!”

Her grin grew wider. She stuck out her tongue at me, but it was no use. I’m a rock, I am.

“Roberta...” I tried to put some kind of authority in my tone.

She stuck out her tongue again and I snapped. I moved across the tub and grabbed her and put her over my knee and swatted her smooth light peach butt. Twice on each cheek. Hard.

Cabroncita, enough!”

I’ve lived here ten years. My Spanish is pretty good although I’m not sure that’s even a real word. Doesn’t matter, it fit the moment, or so I thought. Her sister explained to me later that in the diminutive it’s more of an endearment than an insult. I kind of meant it both ways, anyway.

Roberta wriggled on me and I responded in the manner I’m sure she hoped for. She resisted but I pulled her off me and back onto the seat, manhandling her, probably to her delight. I put my arm around her shoulders and hugged her to me.

“Sweetie, enough.”

I kissed her cheek.

“Enough, Roberta, OK?”

I kissed her again.


She shrugged and mock-pouted but she couldn’t conceal the grin underneath. I felt her hand on my thigh and I stood up and went back to the opposite side of the tub before she reached her target.

“My butt hurts, don Alejandro.” I saw her hand moving under the water. “And I didn’t know you could talk so dirty.”

“Behave yourself, Roberta.”

She stuck her tongue out again. Her hand kept moving. She held my gaze for another minute or so until she seemed to lose herself as her hand moved faster. I was erect but I didn’t move a muscle. She finished with a gasp and sagged back on her bench, eyes closed and a satisfied smile on her lips.

When her eyes opened her impudent grin replaced the smile.

“I’m going to dry off in the sun, don Alejandro. Is that OK?”

She knew it was OK, and even if I didn’t encourage it I liked the view.

“Sure, Roberta, but only in that corner, you know the one.”

She climbed out of the water and without showing off too much made her way over to the corner with the best screen yet still in full sun. She dried herself quickly and stretched out on her towel. Idly I made a bet with myself that her request for help with the sunblock would come within three minutes. I won the bet.

“Don Alejandro, do my back, will you, please?”

I worked her from her shoulders all the way down. Alternated smooth strokes to spread the goop with firm circles and presses to work her shoulders and back. She grunted and hummed in approval. I had no doubt how it would play out. I’d get close to her rear end and her legs would open and all the rest of it. The first part of that was right on target. I admit I spent a little extra time on her firm little bottom, but I was gentle. Her buns were still a little red from my swats earlier. I’m human and my hands had lives of their own as they palmed her and stroked her.

And then I kept going. Down her legs, that is. Her grunts of approval seemed to take on an edgier note when I skipped right over the tempting target between her thighs. Too bad. Even though I spent a little extra time and effort on her thighs I kept going south. When I finished with her calf muscles and moved down to her toes, I heard her sigh.

“Thank you, don Alejandro.”

I patted her bottom once and let my hand linger and extra second or two.

“You’re welcome, Roberta.”

She turned over. Her grin was back.

“Help me with my front, don Alejandro?”

I looked her over top to bottom, from her chest sporting two erect nipples and the smooth barely noticeable mounds that would become breasts some day down past her center with the bare beginnings of pubic hair. It was my turn to grin as I tossed the tube of goop onto her flat stomach.

“You’re on your own, kid.”

She pouted, and when I turned away back to the hot tub I heard her snicker.

I stayed in the water only long enough to catch my breath.

“I’m taking off, Roberta. Behave yourself, OK?”

I thought I heard the local equivalent of a Bronx cheer behind my back, but when I turned to admonish her all I saw was a smile. She waved. I glanced at the apartment building as I opened the door from the azotea to the house proper. The quick flash of sun on a lens confirmed my suspicion that at least one resident was enjoying whatever view there was of Roberta.

I passed Sara on the narrow circular stair. It’s just possible to go by without touching on this thing if you’re careful, but today Sara didn’t even try. Her hand brushed me and I felt her breasts press against my shoulder as she moved past.

“Sorry, don Alejandro.”

“No worries, Sara. Roberta’s outside sunning.”

Sara grinned but she didn’t reply.

Back in my bedroom suite I stripped my swimsuit off and stepped into the shower and took care of urgent matters. By now the signals from both women were too clear and too strong to be mistaken or denied. Roberta’s day would come soon, I promised myself, and I wouldn’t neglect Sara.
