Spa Time with Busty Sister-in-Law

Finally - a few days off work and a long weekend. I just received the approval for Thursday and Friday off of work so I could take some time to relax and unwind from an incredibly stressful couple of months at work. Project after project and deadline after deadline - I was over all of it. I was so looking forward to having a few days off with nothing to do but sit around and do nothing. I sent a quick text to my wife Danielle to let her know that it was done and my time off had gotten approved. I saw the message change from "Delivered" to "Read" then saw the bubbles appear as she started composing a reply.

I waited and waited as the bubbles continued, starting to get worried about why her response would need to be so lengthy. Hopefully she wasn't going to ruin this for me and give me a laundry list of chores she wanted done while I was home. Finally, the notification came through for a new message from Danielle.

"That's awesome Adam! You deserve the time off. I hate to do this to you..." I knew it; here it comes!... "...but my sister Brit asked if she could come stay with us for a few days because she has a friend that's getting married in town."

Oh - that I wasn't expecting. Danielle's sister Brittany was by far her most attractive sister. She had quite a few sisters - each a little crazier than the next, but Brittany was gorgeous. She was a petite little thing with a huge rack - very disproportionate from the rest of her body. Had you not known her, you would swear that they had to be fake; but they weren't. Brittany was about 6 years younger than Danielle and when we were newlyweds with just a couple small babies, Brit lived with us for a couple years after she graduated high school and was getting her feet underneath her. I was happy to have her stay with us - mainly because she often walked around our small home in a little t-shirt and booty shorts; both of which were very generous to her round, supple figure. There was still enough left to the imagination so it was always a treat to watch her go back and forth through the house, doing simple chores like laundry, without the realization that her tiny figure and voluptuis breasts were more than keeping me entertained. After the fleeting memory had completed, I responded to my wifes text.

"When is she coming to stay?"

"She wants to come down tomorrow and stay through Sunday. Is that okay? I am so sorry to spring this on you last minute! And especially since you have Thursday and Friday off. I can let her know it's not going to work and see if she can find someone else to stay with."

No! I thought. "Nah, that's okay. I just plan on hanging around the house anyway, she won't be a bother" I quickly responded. Too quickly? Well, it was too late now to take it back. I'd just have to hope I wasn't being too transparent. It wasn't exactly a secret to my wife that I found Britrany attractive. It's not like anything was going to happen anyway - it's just a nice thought to have her hanging around for me to look at while trying to enjoy some much earned time off. Danielle responded with "awesome - thanks! You're the best!" and that was the end of it. Hmmm...these couple days off may turn out to be even better than I thought...

The next day came and Brittany arrived late in the evening. It had been months since we had seen her and when she arrived, we said all our hello's and hung out and visited for a bit. It was already pretty late and I had to get up early for work so I headed off to bed while the girls continued to chat. They were just in the other room so even after I crawled into bed, I could hear light muttering and an occasional chuckle from them both. It was music to my ears, to be honest. Two of the cutest girls I knew, sitting right in the next room, chatting away. As I drifted off to the soft sounds of their murmurs, my thoughts headed back to the days when we were younger and more carefree.

My dream started out innocent enough. Danielle and I were sitting on the couch with Brittany and one of their other sisters Carla. Carla was another younger, very good-looking sister. We were chatting and laughing and pretty soon, Danielle left the room for some reason or another. I was left in the room, alone, with Brit and Carla and right away they both started flirting with me. It started with a casual, innocent hand on the thigh or a light touch on the shoulder.

It quickly morphed into Brit sitting in front of me on the floor and asking if I would rub her shoulders. I obliged and started caressing her tiny shoulders, slowly moving down her arms and even the front of her chest. She didn't seem to mind at all - in fact, I could see a slight smile on her face and her eyes close as I worked my way down the front of her chest. Carla, sitting precariously close to me, started caressing my thigh and worked her hand closer and closer to my crotch and inside my thighs. Pretty soon my hands were no longer on Brit's shoulders but were down the front of her shirt, under her bra, squeezing and massaging her huge, soft, warm breasts.

Carla had her hand firmly planted in my crotch and was aggressively rubbing my penis though my shorts, very obviously feeling my huge erection. I could feel it throb as she grabbed it and rubbed it and as I continued fondling Brit's breasts, I felt myself getting close to climax. I squeezed and squeezed her breasts as my crotch was rubbed and rubbed and then woke up in a lurch. I ejaculated all over my boxers and felt my penis throb and pulse as it ejected the warm, sticky liquid. I was panting slightly and looked over to see if I had woken Danielle. She was still fast asleep, lightly snoring, oblivious to the events that had just transpired in my dream (and my pants).

The next morning I woke and went to work, anxious to get through the day and start my long "vacation". Work went by uneventfully and soon I found myself back at home. Brit and Danielle were on the couch when I arrived home. Danielle got up and greeted me with a kiss and informed me that she would have to go into the office on Thursday so it would be just me and Brit to "hold down the fort". I immediately started fantasizing about time alone with Brit and all the naughty things I could do to her while Danielle was away. Suddenly I felt embarrassed to be having those thoughts with Danielle just feet away from me. No matter - it all was going to stay in my head anyway. It's not like I was brave enough to actually try anything like what was going on in my head.

Morning came and Danielle headed off to work. I stayed in bed for a bit, scrolling through my phone, until I finally got up around 11 and headed downstairs to find something to eat. Brit was in the kitchen making some scrambled eggs.

"Morning Adam. Want some?", she asked, as I entered the room.

"Sure, that'd be great!" I replied.

"I was thinking about taking a dip in the pool, if that's okay. It's supposed to be super nice out and I thought maybe I'd try to get a little sun and tan before my friend's wedding this weekend. It'll help me look better in my dress," she finished, with a wink in my direction. I melted at her slight grin and told her that the pool might be a little chilly but she was welcome to swim if she wanted. "You should join me! If you want, that is." I shrugged my shoulders and started thinking about whether or not I wanted to traverse the idea of getting half-naked in the pool with this gorgeous woman with no one around to make sure we minded our manners. Again, I quickly pushed the thought aside and went on eating my breakfast.

After cleaning up the kitchen Brit had retreated upstairs to put on her bathing suit. She came back downstairs wearing a super tiny bikini that somehow made her gigantic breasts look even larger. I couldn't help but stare as she walked past and she seemed oblivious, though I don't know how. She had her towel draped over her shoulder and as she walked out the back door, she turned around.

"It would sure be nice to have some company."

I gave her a slight nod, my mind swirling and not completely able to comprehend what I was seeing and hearing. "Sure, I'll be right out." After she closed the door, I bolted upstairs and threw off my clothes, searching desperately for my swim trunks. It was early in the swim season so I hadn't used them yet and didn't know where Danielle had put them after she washed them last. I found them at last and put them on but stopped short - there was no way I could go out back like this. I was already starting to get an erection and I wasn't sure there was any way I could tamp it down or make it less obvious. I was pretty well endowed and when I was hard, just about anyone could tell, no matter what I was wearing or how hard I tried to hide it.

"Maybe I'll go in the bathroom and rub one out real quick so things will calm down," I thought. I went into the bathroom and pulled down my shorts and grabbed my penis. I started rubbing it as it started getting harder and harder. Just then, I realized that we had a camera overlooking the pool in the backyard. It was installed right after we had the pool build so we could keep an eye on the kids as they were swimming. I pulled up the camera app on my phone and started the video over the pool. As the video came up, I could see Brit had already been in the pool and was pulling herself out over the side. I could see the water dripping off of her hair and running down her chest - that beautiful, perky, voluptuous chest.

My dick got even harder as I continued to rub and grab it. She then laid herself on one of the lounge chairs, face down, and undid her bikini top. I almost couldn't stand it. I imagined myself laying underneath her on the lounge chair. She was sitting on top of me, straddling my waist, taking off her bikini top. As she undid the tie, it fell loose and her breasts spilled out, almost smacking me in the face. I leaned into her and put my mouth around her nipple and started sucking. All this time I was watching her on the camera as she lay there taking in the sun. Suddenly, my phone buzzed and a text notification appeared - it was Danielle. Though I was precariously close to cumming, I was instantly taken out of the moment as I read the message from my wife.

"Thanks again for being so cool about letting Brit stay. I know she appreciates it and I know I sure do!"

I ignored the message and figured I should get out back before Brit wondered what was taking so long. I figured most of the work was done - the sudden break in the action caused me to start to go soft so I figured I was in the clear.

I headed out to the back yard and Brit was still lying on the chair, face down, bikini straps laying down away from her back and exposing her bare skin. I could see the sides of her breasts as they were squished out from her laying on her chest. I could feel myself start to get a little hard again and wondered if I shouldn't have stayed upstairs to finish the job. Brit slightly lifted herself off the chair, just enough to turn her head in my direction (but not enough to expose herself).

"The pool was a lot colder than I thought it would be!"

"I'll turn on the spa, if you want. It doesn't take long to heat up," I replied. She nodded in approval and I quickly pulled up the pool app on my phone and got the spa heater turned on. As I waited for it to heat, I slowly made my way into the pool, starting at the shallow end. I figured the sooner I got into the pool the better - it would be much easier to hide my clear attraction to Brit if my waist was under water. And with the pool being as cold as it was, as soon as I got waist deep, I didn't have to worry about being embarrassed by getting an erection.

After wading in the pool for about 15 minutes and stealing a look in Brit's direction every chance I could, I figured I should see if the spa was warm enough to sit in. I got out of the pool and went over to the spa and dipped my toe in it. It wasn't hot, but definitely warmer than the pool.

"Hey Brittany, the spa is warming up a bit if you want to hop in."

She started to get up and off the lounge chair, completely forgetting that her bikini top was unfastened and her breasts were not covered. After sitting up almost completely, she suddenly realized her mistake and threw her hands across her chest.

"Oh my gosh I am so sorry! I totally forgot that I had undid my top! I am so embarrassed!"

Without thinking, I responded with "Oh I don't mind one bit." I instantly blushed at the words that had come out of my mouth and she quickly shot a look in my direction as she was tying her top back in place.

"Oh, is that so?" she responded with a smile. Shit. What do I say now? Is she baiting me? Can I really say what I think to her? I was feeling incredibly brave in that moment and the sight of her bare tits had started me up all over again. I knew I was starting to show through my very unflattering swim trunks. I swear I saw her look down at them as I could feel my penis start to throb between my legs.

"Well, when you were living with us years ago, I think I might have seen you topless in your room once when you didn't realize the door was open so it's not like it's the first time I've seen them". I couldn't believe the words were coming out of my mouth. What was I doing?! I immediately regretted what I had said and made my way into the spa, hoping to hide my erection that was almost full-on at this point. She made her way over to the spa, eyeing my crotch the entire time.

"Oh, I knew the door was open, I didn't mind that you saw." My head was spinning. Did I just hear her correctly? She knew I could see her topless and she LET me? She walked into the spa and sat down across from me. "You know, I've always thought you were pretty hot and have been jealous that Danielle snapped you up and gets you all to herself," she said. My heart was pounding. She had no idea how many times, when she was living with us, I would see her walk around in her bra and panties and I would go off to my room, lock the door, and jerk off, imagining her putting her breasts in my face, sucking on her nipples, sticking my fingers in her vagina, or sitting her on my lap and letting her ride my cock while her huge tits bobbed up and down. Suddenly, she got up and stood directly in front of me. "Sit on the edge of the spa," she said.

I froze.

"What?" was all I could say in response.

"Get out and sit on the edge of the spa. Please," she repeated. I stood up and sat outside the spa on the edge with my feet dangling In the water. She leaned and whispered in my ear, "I want to show you just how much I've wanted you." She lowered herself into the water, her face at the level of my crotch. She came closer to me and grabbed the sides of my trunks and started pulling them away from my hips and down my legs. I lifted my butt so she could work them off and as soon as they cleared my crotch, my dick stood at full attention in her direction. She looked down and a quiet "wow!" escaped her mouth.

I looked at her as she examined my penis and gently licked her lips. At that moment my penis throbbed and pulsed and we could both see it move. She slowly put her hand around it and brought her mouth to just the tip. She slid the tip of my dick across her lips and I moaned quietly.

"Oh, you like that, huh?" she said.

I nodded. She then opened her mouth and stuck my cock deep inside her mouth and down her throat. I could feel her wet, warm tongue work its way around me and I leaned into her and arched my back. Oh my god this felt so good. I couldn't even believe it was happening. She took my penis out of her mouth and stood back up and again unfastened her top. She let her bikini top drop into the water, exposing her perfectly round, huge, beautiful breasts. She then stood on the step inside the spa to make her breasts the same level of my head.

She moved close to me and grabbed the back of my head, pressing her breasts into my face. I could feel her wet tits on my face and opened up my mouth, seeking to suck on her dark, small nipples. I sucked on her and bit down gently. She moaned and gasped. I grabbed her other breast with my hand and cupped the one I was sucking on with my other hand. I squeezed it and worked as much of her breast into my mouth as I could. It didn't seem like much - her breasts were so big that there was no way I was fitting even half of it into my mouth. But dammit, I was gonna try.

As I continued to suck on her nipple and breasts and squeeze the free one, she reached down and grabbed my dick. She slid her hand up and down my shaft and it became increasingly clear that I was going to cum soon and I was going to cum hard.

"You are so fucking hot I am going to cum so hard," I said, with my mouth full of her tits.

She released her hand from my dick and sat back down in the spa, quickly putting her mouth around my dick. She sucked and licked and used one hand to grasp the shaft of my cock and the other to caress my balls. She took my dick out of her mouth.

"I want to suck the cum out of you."

I let out a whimper and she resumed sucking on me and using her tongue to slide around the tip of my penis. Her hand that was caressing my balls slowly moved further and further back between my legs until she was right at my anus. I wasn't sure about this - I had never explored with anything anal and didn't know if I would like anything being in there. But I was so caught up in the moment and what Brit was doing felt so good that I was willing to let her do anything to me.

Sure enough, after just a few minutes of her rubbing around my anus, she slowly stuck her finger inside of me. As soon as she got past the initial opening, I could feel her rub against something that made me gasp. It. Felt. Amazing. She continued to thrust my cock in her mouth and as far down her throat as she could, moaning and humming while she was sliding it in and out which caused a vibration that was starting to take me over the edge. She slid her finger gently in and out of my anus, hitting a spot on occasion that made me feel waves of pleasure all through my body.

Then, without warning, I felt myself ejaculate in her mouth. It shot out of me so hard that I couldn't help but moan and whimper. I grabbed the back of her head and pressed her into my crotch as my dick continued to throb and pulse and release the liquid into her mouth. I had never felt myself cum that hard or long before and she continued to suck down what my dick was offering. As I finished up, she slowly worked my dick out of her mouth and looked up at me with a slight smile on her face.

"Well, that was fun!" was all she said.
