At forty, a birthday isn’t really a big deal. But to me, it is better than any day of the year— even better than a six-year-old’s Christmas. You see, every year, on my birthday for the last ten years, I get a very special birthday surprise.

The surprise is about 5’2”, with sexy green eyes, full little lips, an ample set of juicy, round tits, and one of the nicest asses you have ever seen. Her tiny body sits on the nicest, tannest set of legs I’ve ever seen, all held up by the cutest, pedicured little feet on earth. Once a year, I get to do anything I want to this little sex pot—even though she’s my wife’s baby sister.

It all started ten years ago. Elizabeth—or “Lizzie,” as we call her—moved in with us. I worked a lot and didn’t pay much attention to what was going on at home. Focused on my career and success, there was very little to distract me. One day I was on the phone for a pointless work call, preoccupied and walking around, when I wandered into the backyard. I was thinking about the in-ground pool and the brand-new hot tub we had just installed. I hadn’t been in either.

So focused on work lately, I hadn’t taken one moment to enjoy the fruits of my labor. I listened to the endless babble on the other line as I walked to the diving board. I set the phone down and peeled off my clothes. I stood on the diving board, naked. The sun felt great on my 6’0” frame. I reached down and grabbed an inch of fat—a little too much for my liking. To stay looking good, I needed to start a fast and cut this extra body fat down. I regularly hit the gym, but I had just been too busy lately.

I stared down at my cock, now a little aroused and warmed by the sun. I grabbed it and flopped it back and forth. Just grabbing hold of the shaft had it at attention. It doesn’t see much action anymore—what a shame.

I dove into the water and swam around. It felt great—exhilarating, and naked. I hoped that old bitch neighbor was watching! I swam to the edge of the pool and pulled myself up, lying on the concrete to dry off in the sun. I closed my eyes and relaxed. Suddenly, above me, I heard a smart-ass little giggle. I opened my eyes to stare directly up a pair of tan legs into the crotch of a red bikini outlining the shape of a sweet little muff.

“Jesus, Lizzie! I forgot you were here,” I said, startled, as I tried to cover myself up.

“Relax, I don’t care,” she replied in her sexy little voice. “Besides, no one else is here. Unless you want to count your bitch neighbor lady watching.”

Lizzie held her middle finger in the direction of the neighbors, and I glanced just in time to see the old bitch close her blinds.

I got up and walked to the corner of the patio and tied a towel around my waist. Lizzie walked over and sat at the patio bar, sipping a daiquiri, and proceeded to roll a joint. I assumed she had been there the entire time and seen me strip and jump in.

As I went for my clothes, Lizzie stepped into the hot tub. Holding two drinks, she chirped, “Hey, grab that joint and lighter for me.”

I slipped on my boxers and walked toward Lizzie, grabbing the joint off the bar. I couldn’t help but stare at her gorgeous little ass as she stepped down into the bubbling water. Her tan little cheeks were barely covered by the thin piece of red fabric.

“Daiquiri?” she demanded, handing me the other drink she was holding. I watched her eyes look down my body and stop on my boxers. She giggled.

“You didn’t have to cover up.”

“Yeah, about that. I kinda forgot you were staying with us.” I grimaced.

Lizzie had gotten into some trouble back home, and her sister sent her a plane ticket to fly out and stay with us.

“Jesus, Jimmy, I’ve been here a year. Seen you about twice since you picked me up from the airport. When are you even at home? I bet that’s the first time you’ve been in the pool. I know you haven’t been in the hot tub! Please, please join me? It feels great and you need to relax! Come in…” she begged.

Fighting every rational thought in my head, I lit the joint and handed it to Liz. Then I stepped into the hot tub across from her. We passed the joint back and forth in silence. She stared at me and chuckled.

I really didn’t know Lizzie very well. It seemed like she was just a little girl when I married her sister and whisked Emily away. They had come from a trash family, and when I met my wife Emily, she wanted to get as far away as possible. We eloped and started our life. Young and energetic, we both built successful careers.

I had barely thought of Elizabeth in years—until I picked her up from the airport. I was stunned at how mature she looked and acted. She was very much a young woman, and I realized she had to grow up fast living in her disgraceful childhood. It angered me. I drove her to the shopping mall and let her buy whatever she wanted. I took her out to dinner, and we had interesting conversations. I felt a very deep connection. Staring into her eyes and watching her beautiful smile, I couldn’t help but feel a deep sense of attraction and lust for this girl.

“Jimmy, do you want another daiquiri?” Her sexy voice jolted me from my thoughts. I must have been a little stoned. She grabbed my glass, and I watched her ass bounce as she walked away. She turned on some reggae music down low and swayed to the rhythm as I watched her dance.

I could feel my dick thicken as I wondered how tight her little puss must be. She danced her way back to me like a slow, methodic belly dancer. Sensual and sexy, she had the most mischievous grin as she entered the water and danced above me. She turned around with her back to me and moved her ass seductively in front of my face. Her skin was so dark, and her bright bracelets and white fingernails accentuated her flawless tan.

I watched her hands trail up her back and undo her bikini top. I could barely breathe. I should stop this! But never in my life had I been more seduced, or wanted something more.

Her bleach-blonde hair fell over her big tits as she turned to face me. Her eyes were closed, and she slowly pulled a foot out of the water and gently splashed me with a giggle. Her foot found my chest, and she traced my nipple with her sexy white-painted toes. I grabbed hold of her sweet little foot and kissed the sole, slowly licking from her heel to her toes.

Lizzie let out a murmur of satisfaction as I nibbled her toes and began to suck on each one—teasing, gently biting, and sucking.

Lizzie had her eyes closed, and I could tell she was in ecstasy. I let her foot go and grabbed her by the waist, firmly pulling her down onto my lap. She ran her fingers through my hair and around my neck, her nails lightly scratching down my back.

Our mouths locked together furiously. I had never in my life wanted a woman more. Our tongues and lips explored each other’s mouths, intertwined lustfully. I held her tightly as she threw her head back and pushed her breasts to my mouth. My tongue encircled each nipple, and I gently nibbled on each nub. Her hips bucked into me, and she ground her wanting puss against my clothed cock.

“Oh, fuck… I want you, Jimmy,” she moaned, then stood up and dropped her bikini bottom. My eyes locked onto her sweet nirvana, mere inches from my face. I could smell her sweet juices. Her muff was shaved into a perfect blonde strip that followed down to a glistening set of perfect pink pussy lips.

I slowly traced down her shaved trail and circled my finger around her clit. Lizzie bucked as I entered her with my finger. I slowly worked my finger in and out. Surprised by her tightness, I continued to work her clit and tease my finger inside her. I pulled her close and began to suck on her clit as she bucked into my face. I tried to be gentle, but she tasted so sweet, and her intoxicating smell had me hungrily devouring her.

“Oh, god… that feels so fucking good, I’m going to cuuummm!” she yelled out loudly.

Lizzie’s nails pulled my head into her as she gasped and quivered, her knees buckling. I could feel a warm gush as she came, and I caught her, gently laying her down on the deck.

She lay on her back and smiled at me. “That was so fucking amazing… now it’s my turn.”

She wasted no time and finally released my throbbing dick from my boxers. I was rock-hard, and Lizzie took me deep into her mouth. She gazed into my eyes as she sucked me like a pornstar. I could tell this wasn’t her first blowjob by far. She twisted her hands around my cock and used her tongue on my balls. Throating and gagging me as she moaned, I was about to explode.

The sight of this blonde angel performing voodoo on me was exhilarating.

I let out a moan—“Fuck…”—and my whole body electrified as I shot a giant load into Lizzie’s mouth. She gagged, spit, and swallowed as much as she could, but the huge load spilled out over her lips and my cock. She licked me clean, looked up at me, and smiled.

“Happy Birthday. I’ve been waiting for this,” she said cunningly, wiping her mouth.

Birthday? Damn, I had forgotten it was my birthday.

“Did she even call you today?” she asked, referring to her sister.

“No, she’s out of the country for business, you know this, Liz. She’s probably busy—I’m sure she’ll call tonight,” I defended my wife.

“It’s okay. I planned on having a little party for us anyway,” she replied as she walked away, her tight ass swaying sensually.

She called over her shoulder:

“Let’s go inside… are you coming, birthday boy?”
