Sorry for the delay - but hopefully you’ve read the first two parts of my fun times with my wife’s sister. This one’s a bit longer, so I hope it makes up for the wait.

So, once Vanessa and I had finished our drinks and cleaned up, we went into the house to shower off the fun we’d just had in the hot tub. Not much to share there since it was late and we were both pretty spent. She’d played ball all day, and I’d just had the best fuck of my life, so we cleaned up and said goodnight. She went to the guest room and I went to the primary bedroom I shared with my wife, anxious as hell that she’d figure out what we’d done in the tub. Somehow, I managed to fall asleep.

My wife, Kim, is a nurse, and she typically works four days then four nights, then five days off. Last night was her final nightshift, so she was off for the next few days. Maybe I was feeling a bit guilty for banging her sister, so I focused on taking care of pretty much everything she’d been asking me to do for the last few months. If wives knew how productive their men can be with just a little something on the side, they’d be out there finding us a sidechick themselves.

I cleaned the house, the garage, and her car. I mowed the lawn, went with her to get groceries, and treated her to a nice night out at our favourite restaurant. Looking back, I probably should have said something to her. We’ve always been open about everything, but this was her little sister, so I didn’t tell her. Eventually I started feeling less guilty, but I still tried to make sure I was being a pretty decent husband.

Later that month, Kim was going to a conference out of state and I couldn’t get away from work to join her. She’d be there for three days, but we both knew she’d be fine. She’d be there with friends from work, and we both knew she’d have fun, but nothing too crazy. It’s not like she was going to Vegas for a friend’s bachelorette party - but that’s a different story.

After dropping Kim off at the airport, I made it back home, burned a nice steak and a fat doob, then headed out to the hot tub to enjoy a soak and a bourbon. I was in there for barely twenty minutes when I heard the backdoor slide open, and a couple of voices heading towards me.

“See, told ya he’d be in the tub,” said a familiar voice.

Vanessa walked towards the tub, wearing a white crop top with a torn neckline that invited the eye to the magical space between her delicious C-cups, and daisy dukes that hugged her firm ass like a glove. Beside her was a stunningly beautiful Chinese woman wearing a blue sundress that flowed like silk against her pale skin. Her jet black hair cascaded over her shoulders, and I have no idea why I wanted to feel it between my fingers, but the urge to reach out and touch it was almost impossible to resist.

“Justin, this is Cassie,” said Vanessa. “Cassie, this is Justin.”

I just smiled and waved. I was awestruck by this new guest’s beauty and didn’t trust my mouth to say anything without sounding like a gibbering idiot, so I just kept it shut.

“Hi Justin. Nice to meetcha. ‘Nessa has told me a lot about you,” she said, with a wicked grin.”Can we join you?”

I just nodded and waved my hand to welcome them into the tub. My jaw dropped as Vanessa pulled her top off, revealing her flawless body and delicious curves. Once her clothes hit the ground, Cassie stared into my soul then undid the delicate bows of her sundress. Her dress didn’t fall down - it glided, revealing milky white skin and delicately defined abs. The soft mounds on her chest were high and proud, with the pinkest areolae and rock hard nipples. She was maybe a B-cup, and they looked amazing on her lithe, muscular frame. My eyes kept travelling down, appreciating the work that she’d put into this body, and my reward was a dark patch of fur between her legs. It was a good sized bush and perfectly trimmed.

The girls slid into the tub, so there I was, with a babe on either side of me. I filled up my glass then handed them the bottle. They each took a swig, and seconds later I felt a different hand on each of my thighs. Vanessa turned my head to her, and pulled me into a delicious kiss while Cassie’s hands wrapped around my already hard cock.

“Well damn, that is thick,” she said, then grabbed my chin away from Vanessa and brought my lips to hers. I was in heaven.

I put my arms around the newcomer, feeling her soft skin in the warm water, and then I gently pushed her body up, kissing my way down her muscular frame as I placed her feet on either side of my hips. Most of her body was out of the water now, and I took a moment to enjoy the way the water dripped off her dark mound. Then I dove in, burying my nose in the soft hair and exploring her with my tongue. I reached up to pinch and pull her nipples, and her moans let me know that she was enjoying what I was doing. After a few minutes, she had her hands behind my head, pushing me deeper into her, Her moans sped up as she fucked my face, and I kept on doing what we were both enjoying. A few minutes later, I felt her entire body tense, and then I tasted the orgasm as it rippled through her.

As we relaxed and waited for Cassie to stop trembling, I looked over at Vanessa to see her pinching her nipples with one hand while the other was underwater, flicking that delicious bean of hers. She saw that I was watching, and licked her lips with a smile that was so sexually charged that I just about came right there. God damn, she is an amazing sister-in-law.

“That was nice,” cooed Cassie, “but the reason I came here tonight was for this,” and with that, she reached down to my achingly hard cock, then slid her body down to wrap her lips around my sensitive head. I felt her stretching to take it in, and she had to slide up and down a bit to fully engulf it. But the smile on her face as she slid up and down, knowing that she was being fully stretched, well, that’s a memory I’ll keep in my spankbank until the day I die.

Slowly at first, Cassie rode me in the tub. Her knees were just skimming the surface of the water, and I had two hands full of ass to keep her steady. She was so tight, and while I usually don’t have any issue with stamina, I knew it wouldn’t be long before that final moment.

“Oh fuck, I’m so close,” I whispered. “Where do you want me to finish?”

“In me. Cum in me. I want to feel you explode within my body,” she replied in an incredibly husky voice.

And then I was there. Load after load, going deep into her tight pussy. I could feel her gentle muscles milking every drop out of me, and then her trembling again as she had her second orgasm of the night.

She lay her head against my shoulder, and we just sat like that for a bit. The splashing noises of Vanessa standing up drew our attention, and we both watched as she sat on the edge of the tub, her legs wide open to show us what she was doing with her long fingers. Her fingers were a blur as they massaged her clit and she gently rocked her hips in rhythm with her fingers. A few moments later, she reached up and pinched one of her nipples so hard I was worried she’d hurt herself, but she threw her head back and moaned loudly as the orgasm raced through her. Her fingers slowed, but her breathing was still ragged. I felt Cassie’s warm pussy constrict against my cock, which was beginning to harden again – from the show, from the smells, from the sight of these two beautiful naked women beside me.

After a few moments with nothing on the air but the sound of our quickened breathing, Vanessa smiled at us and said, “Let’s go inside and make this night memorable.”

Understatement of the fucking century, but that’s a story for another time.

After Cassie and Vanessa had gone home, I sat by the TV wondering what I’d done to have such a great life. My phone rang and it was Kim. She sounded a bit tipsy, giggling and slurring a bit, and while I’d just had an amazing time with Vanessa and Cassie, I couldn’t help but wish I was in that hotel with my wife, because when she drinks, she gets so very, very horny. I could hear the sounds of porn in the background, and I was just imagining her running her fingers all over her tight little body. She told me about the conference and what they’d been doing, then dropped a bombshell on me.

“Wanna know something funny?” she asked. “ ‘member the security cameras we put up in the yard because of those stupid kids next door?”

My stomach dropped as I had forgotten about them - even though one of them had a direct view of the hot tub.

“Sometimes, when it’s slow at work,” she said. “I like to check in on you when you’re in the hot tub, cuz you’re pretty damn cute and I like to see you naked.”

Oh fuck. Oh fuck. Oh fuck. - times a million. That’s what was racing through my head.

“I got to see you and ‘nessa having a grand old time. And while I probably should be jealous, it was kinda hot. Like, really hot. And then watching you be the perfect husband for the rest of the week, that was pretty hilarious.”

“But now I kinda have a situation, and I thought it would be best to let you know. Katie, that cute little RN that you drooled over at the last Christmas party, well, her husband came along for the trip. He’s a fireman and pretty damn sexy. Well, one thing led to another, and you might not believe it, but right now, his wife is eating my pussy while he’s fucking her. They’ve got a camera set up, and I cannot wait to watch this with you when I get home. You might wanna rest up until I get back there, cuz I’m going to ride that sweet cock of yours until you beg me to stop.”

I can’t share the video, but let me know if you’d like me to tell you about Kim’s adventures at the conference.
