"Alright I'll see you guys day after tomorrow," I said and waited until the receiver was in the cradle before I released my frustrated sigh.
My sister Kathy and her son James were coming to stay with me while she sorted out her breakup with her second husband. There was no room for them in my tiny apartment but I couldn't tell her that since I was about the only option she had.
We lived fairly close to each other now but far from any other family and since she had moved to the Northwest to be near me when her first successful marriage had tanked after twenty years, she didn't have too many friends here.
This most recent joining had lasted only about a year since James didn't get along at all with Nathan. At nineteen years old he seemed to hold more sway over his mother than he should. I was apprehensive about having them here but mostly I was trying to figure out where the hell everyone would sleep.
I had a queen size bed in the only bedroom and a couch in the living room but there wasn't any more room for a third body to bed down. There wasn't even a decent amount of floor space to put down a mat and sleeping bag.
I sighed again annoyed at the thought of losing my privacy and disrupting my precious routines. At forty one and single again I enjoyed a lot of me time. I was reluctant to give that up, as much as I loved my sister.
I did what I could to prepare for them and had food stocked in and extra TP and such. I felt as ready for the invasion as I could be.
When they arrived I welcomed them and we sat and talked over lunch.
"Kathy," I said, "I don't know where we are all going to sleep. There's just not much room in my little place. I'll give you my bed and take the couch but James is a big boy and I don't see a lot of space for him to lay his bones."
"Oh that queen size in your room can handle two. James can snuggle in with me, we'll be fine."
That thought hadn't even occurred to me. At 39 my sister hadn't lost her looks and her body turned a lot of guy's heads I'm sure.
"Oh, OK" I stuttered a little shocked and I could feel myself blush as I thought what it would be like to 'snuggle in' with my younger sister.
"What's the problem? Why are you blushing?" My sister asked. "My baby and I can share a bed that big don't you think?"
"Yes. Yes." I stated stupidly.
My nephew smiled at my discomfort. He had no problem bedding down with his mom.
After dinner and a little TV we all said goodnight and I struggled to get comfortable on the couch. I had slept fitfully for a few hours when a sound woke me and I listened for a moment.
There was a thump and a soft ssssh then I heard my sister giggle. I quietly moved the comforter I was sleeping under and put my bare feet on the floor. Moving as silently as I could I tiptoed to the door. Listening intently I heard the bed squeak and Kathy said, "Slow and easy baby. We don't want to wake up Billy."
My name is Bill and my little sister is the only one who gets away with calling me Billy anymore.
"Mom your pussy is the best I've ever had," said James.
"You say that every time we fuck," Kathy said. "Are you just trying to get me to tell you how much I love your cock inside of me?" My sister asked.
As I listened to their exchange, my own cock stiffened under my boxer shorts. They stopped whispering and I heard a moan from my sister as the bed started to squeak rhythmically. My nephew grunted as he started to fuck his mother faster and as hard as they tried to be quiet it would have been difficult for anyone to mistake what was happening in my bed.
"Honey you're going to make Mommy cum," my sister tried to whisper but it came out as more of a stage whisper which I heard clearly through the door. James was more excited and louder when he said, "Mom your pussy is so tight and warm I'm coming with you."
Their panting and the sounds of the bed sped up and there were more moaning grunts and then everything went quiet. My dick was in my hand and I came right after they did, having the presence of mind to catch most of my ejaculation in my hand.
Holy shit, had that just happened? My sister and her son had just fucked each other in my bed and it wasn't the first time they had fucked. I thought, 'that lucky little bastard. I'd like to fuck Kathy.'
I snuck back to the couch after wiping cum off my hand with a paper towel in the kitchen.
James had a job to go to a few miles away and as Kathy and I sat at the table drinking coffee I couldn't help looking at her in her light robe. Her tits jiggled when she moved and she kept looking speculatively at me.
"You heard didn't you?" she finally asked.
My red face was enough of an answer and I looked away from her face.
"It sounded like fun," I finally said. "How long has it been going on?"
"I gave him a blowjob for his eighteenth birthday and that's when he and Nathan really started butting heads. As Nathan and I started growing apart, I welcomed James into my bed as often as possible. He loves his mom's pussy and he really knows how to please it. My tubes have been tied since shortly after James was born so there was no risk there."
I moved uncomfortably in my chair and her eyes locked onto me. "Are you getting hard? I thought I felt a couple of wet spots on the carpet this morning. Did you come outside the door while we were fucking?"
My face was now beet red and I nodded slowly.
Kathy's reaction was totally unexpected as she opened the top of her robe and exposed a beautiful set of tits.
"We can't let James find out but if you need to get laid as much as I think you do, I'll do you brother."
I stood up and my boner pressed out against the sweats I had thrown on this morning.
"Come here," said my sister, "should I suck you off or do you need to fuck your baby sister?"
As I hugged her I slipped her robe off and it fell to the floor.
"Oh I see. Right here on this cheap table of yours or in your bed?"
"Bed." I grunted and kissed her on the lips for the first time ever.
"We should do it on a towel so James doesn't see the mess we're going to make." She said.
I shed my clothes and went into the bathroom to grab a towel. Kathy walked naked into the room and waited for me to place the towel on the bed and then lay down and spread her legs for me.
I looked at her pretty bush and got on the bed between her legs. There was no pause, no foreplay, Kathy took my cock in her hand and guided it into her pussy. Just like that I was fucking my little sister. James was right it was the best pussy I had ever felt too. Kathy's muscle control had me on the edge in less than five minutes. She felt the change and put a hand on my chest.
"Hang on there cowboy. I get something out of this too."
That brought me back and I looked down at her lovely face. I kissed her and held still until I regained control. I kissed her again and moved a hand to her tit, squeezing her nipple and leaning down to kiss it.
Kathy's hips started to rock and we started fucking again but slowly. Her moans started to increase and we sped up our rhythm.
"Oh fuck I'm gonna cum," she said and I started thrusting faster.
With a loud moan from her and a couple of long grunts from me, we came.
"Wow why didn't we ever do that before?" I asked.
"Well... Mom and Dad?" My sister wisely answered.
"Yeah but God James was right, you've got a really hot pussy. I almost couldn't stop to let you catch up."
"Well since you did and you will in the future I guess we're going to have to keep doing it." She said.
"I was hoping you'd say that. Can I keep listening to you and your son fucking too?
"It's up to you. Do you want some of my panties to catch your cum in?"
"Oh that would be nice. I used to jerk off in your panties when we were younger."
"No shit. You think I didn't notice. They'd be missing for a few days and then show up in my drawer all clean and sometimes even still warm from the drier. You must have been thinking with this head only," she said as she squeezed my hardening dick. "Just thinking about using my panties again got you going?"
"Yeah. Did you offer to suck me off just before we fucked?"
"James will be home in a half hour. Think you'll like my mouth as much as you guys like my pussy?"
"Willing to try," I said nudging down on her shoulders.
"Oh you think we're in a hurry now is that it?" She said as she kissed her way down my chest and across my stomach. Kathy licked around my pubes for a bit and then licked the head of my cock.
I cupped the back of her head in my hands and slid my prick into her warm mouth.
I threw my head back and moaned as my sister started blowing me. Her technique with lips tongue and very lightly with her teeth rivaled the feel of her tight pussy.
I let myself enjoy the whole sensation while thinking about her and James last night in this very bed. Before I even knew it I shot my sperm into Kathy's hot mouth.
She looked up at me as I finished and she waited until I pulled back. She licked her lips and swallowed.
"Don't you warn a girl before you fill her mouth?"
"Sorry Sis, it just felt so good and I was thinking about you and James last night and I came before I knew it was happening."
"You really like that I'm fucking my son in your bed. I bet you'd like to be able to watch us wouldn't you."
"Oh Kathy," I said palming one of her beautiful tits. "I'd love to watch you two fuck. That'd be one of the coolest things ever. Not as cool as what we just did though. I really want to keep doing that."
