My wife's uncle was turning 70. As his kids lived in different places around the country, he was having it in a nice country hotel near where he lived, that way anyone who didnt live nearby could get a room in the hotel and stay over. This included my wife (50) and I, her sister (54) and her husband and her mum and dad.

My wife, Louise is petite and blonde. Nice body, great ass and smallish tits. Her sister Caz is similar build but taller and more of a brunette. She also has a great ass but has even smaller tits than my wife. She definitely falls into the MILF category though and I had flirted and fantasised about her for years without it ever going anywhere.

They both looked really good for their ages and had made an effort for the evening, albeit fairly conservatively with trousers and nice blouses. They were both the most attractive women in the room, without doubt (although some of the younger generation had more flesh on display!).

The evening itself was pleasant enough, with a nice meal and then those who wanted to having a few drinks afterward. Being a hotel, the price of drinks was a bit on the high side, but we couldn't really complain as the uncle had paid for the meal.

After the meal, we sat in the bar with all of my wife's cousins. There were 5 cousins in all (now all in their 50's), their partners and various grown up kids. The cousins had all grown up together but hadn't seen each other for a while, but the rest of us only ever met at weddings and funerals so didnt really know each other well.

I was sitting beside my Brother in law (Jim), who I did know pretty well, but didn't really like that much as he is a bit of an asshole. We generally got on ok though, so it wasn't a terrible evening.

After a while, it was clear most of the conversation centred around the cousins growing up and Jim and I decided we had had enough. We had both driven down, so used the excuse that we we tired after the long drive and were going to head off to bed. I made it clear to my wife that she could stay and enjoy seeing her cousins, and headed off to our room.

I'd had a few drinks by this point and genuinely was tired after the drive, so it didn't take long for me to get to sleep. I tend to sleep like a log, so it wasn't a surprise that I slept straight through till morning.

It took me a few minutes to realise where I was when I woke up. The room was still fairly dark, although there was a suggestion of light coming into the room which showed it was morning. I was in my usual position perched right on the edge of the bed facing out, which is where I often sleep. Deciding to doze a while longer, I turned over, but couldn't go far as Louise was on my side of the bed, pretty close to me.

We have a huge bed at home and normally like our own space for sleeping, but its not unheard of for her to lie diagonally or on my side, especially after a few drinks.

Anyway, I wasn't going to make a big deal of it and turned over beside her. She was facing away from me, so I ended up spooning her from behind.

Sometimes on a Sunday morning, we enjoy sleepy morning sex. This would involve me sliding over to her side and spooning her for a while till she felt my hard cock pressing against her and it would lead from there.

While I hadn't intended that this morning, the fact we had ended up in this position and we were in a hotel room... what else was I going to think about?

I sleepily wrapped my arm gently around her stomach as my already stiffening cock started to press against her ass. We lay like that for a while and I think I even drifted off again for a bit. I don't think she had woken up at all.

Through my sleepy haze, I was gently pressing my hard cock against her ass cheeks. We normally both sleep naked, but it felt like she still had her panties on. As I moved against her back, I realised she still had her bra on too.

I hadn't heard her come to bed and had a chuckle as I realised she had probably stayed up pretty late and was very likely hammered when she got into bed - although I hadn't known her to be drunk enough not to take all her clothes off.

Anyway, at this moment in time, I was enjoying very slowly pressing my hard cock against what I now realised was her silk covered ass. I had been doing it for a while when I felt her stir and gently press her ass back against me.

She moved her hand behind her and ran it along my thigh. Taking this as her indication she was happy to play, I gently pulled her panties to the side and adjusted so the head of my cock was pressing against her very warm and now very moist pussy. With minimal movement she adjusted her pussy and I felt the head of my cock slipping inside her.

It felt great and while normally there is a temptation to start frantically thrusting, the fun in sleepy sex is to take it nice and slow.

I therefore slowly slipped the rest of my cock inside her till I was pressed hard against her ass and she had all of me. We both made little sighs/groans of pleasure as I slowly adjusted and felt my length slip out of her again, before very slowly sliding back in.

This carried on for a few minutes and I was beginning to fuck her a little harder when she let out a gasp. I thought it was a gasp of pleasure till I felt her tense and pull away from me so that my cock slipped out.

"No!" she whispered in a panicked voice.

I had no idea what the problem was when I got the shock of my life...

"Don't stop," I heard another voice whisper.

It was a voice I recognised. I lifted my head and looked past my wife to see Caz lying on the other side of the bed!

I would later find out that while I was happy to leave Louise to chat and catch up with her cousins, Jim hadn't been in the same frame of mind. He had gone back down to the bar and tried to tell his wife to go to bed. They had got into a massive argument which had apparently ended with her telling him she wouldn't be going back to their room at all. After dealing with the upset and tears, my wife had tried to get her another room, only to be told there were none available.

She had therefore said she could sleep in our room. she had intended to kick me on to the floor, but as I was sound asleep, on the edge of the bed, they decided there was enough room for the three of us. They had both stripped to their bra's and panties and climbed in beside me, while I was totally oblivious.

Having had a late night and a lot of wine, Louise had been enjoying the morning sex until she remembered her sister was lying beside her, prompting the reaction I had just experienced. She hadn't even opened her eyes until she remembered.

"What?" Louise asked somewhat surprised.

"Keep going," Caz replied, "I don't mind, it's actually quite a turn on."

Louise didn't move or react, but there was no way I was letting this opportunity go. I pulled her back toward me, rubbing against her again before pulling her panties out the way and slipping inside her again.

She gasped as I did and I started to fuck her more vigorously than I had before. I also lifted my head a bit so I could see past her to her sister. She was lying on her side facing us. The duvet covered her chest but I could see her bra straps through the half light in the room. She was looking straight at me and as we made eye contact she bit her bottom lip slightly in a very sexy manner. I looked down and realised she was probably playing with herself while watching us.

Louise must have still been drunk from the night before (apparently they had only been in bed for 3 hours) because there is no way she would have had sex in front of her sister sober, however she had closed her eyes and was just enjoying letting me fuck her.

I couldn't stop staring at Caz as i continued to thrust in and out of Louise. We were keeping eye contact and I could sense that her breathing was deepening. As I fucked Louise, i pulled her bra strap off her shoulder and used my hand to knead one of her tits. I squeezed and massaged it tweaking the stiff nipple. The duvet had lowered and Caz continued to watch fascinated as her sister was getting more and more turned on.

Being watched like this, by my sister in law, at such close quarters was a major turn on and there was no way I was going to last very long. From the noises she was making, I didn't think Louise would last long either.

I took my hand off her tit and slipped it inside the front of her panties, rubbing a circle round her clit as I fucked her.

Soon I had to let go and I shot my cum deep inside her. She gasped and let out a moan as she felt me cum inside her and my finger continued to rub her clit. She shuddered with orgasm on about my third spurt inside her and we both gasped and relaxed.

Caz had clearly been rubbing her clit more frantically as we built toward climax and I could see her chest heaving slightly as we came. However, she stopped when we did and we all lay still for a few seconds.

Louise was obviously realising what had just happened and obviously felt a bit awkward about it. I had left her with a pussy full of cum which I was guessing was now leaking into the panties she was wearing. She was obviously a bit embarrassed and mumbled something about going for a shower before climbing over me amd disappearing quickly into the bathroom.

I was left lying in bed with her sister (which I am not sure she had thought through).

"Did you have fun?" Caz whispered, smiling.

"Abosolutely," I replied, "did you?"

"Hmmm, not as much as I would have liked," she replied, biting her bottom lip again.

Just at that point we heard the toilet flush and the shower start in the bathroom.

"Anything I can do to help?" I asked.

"Maybe," she smiled as she lifted the duvet slightly revealing her matching black bra and lace panties.

I moved toward her and slid my had down her belly inside the top of her panties. I felt some light pubic her before her soft lips and hard little clit, which was slightly moist. I ran my finger round it and she gasped before moving her face toward me.

I could feel her warm wine smelling breath on me as I played with her clit. I felt her reach for my still hard and sensitive cock. It was still wet with our combined cum and she slid her hand up and down the length of it.

Suddenly she planted her mouth on mine, slipping her tongue inside me. I kissed her back and at the same time slipped two fingers into a very wet and tight pussy.

She was obviously very turned on and kissed me hard as she squeezed my hand between her thighs. I was fucking her with my fingers as she continued to press her face against mine and rub my cock at the same time.

I felt her tense and shudder and a flood of juice ran past my fingers as she came in several waves. It had only taken a couple of minutes as she had obviously been close and she had got me very hard again.

"Thanks for that, it was amazing," she whispered as she kissed me again then pulled away from me.

"I better go see what this dickhead has to say for himself," as she climbed out the bed.

I couldn't help but watch her ass as she pulled on her trousers and quickly dressed. as she was pulling her shoes on, I quite deliberately put the two fingers I'd had in her pussy in my mouth and sucked the juices off them.

"Hope that tastes good? Got to go..." she smiled and left the room.

A couple of minutes later, the shower stopped and a few minutes later Louise came out the bathroom with a hotel robe on.

"Where's Caz?" she asked.

"Gone to speak to Jim," I replied. "you might have given me a heads up she was here!".

"I was sleeping!" she replied, "can't believe we had sex in front of her."

"It was quite sexy," I played it down, "and you seemed to enjoy it." I smiled.

"Yeah, it was quite a turn on" she smiled.

"I know, I'm still turned on, look," as I pulled back the covers to reveal my rock hard cock.

"Really?" she laughed, "I think i'm too rough."

"Well come lie here and I'll make you feel better." I replied.

"Ok" she said taking her robe off. "But hopefully no one is watching this time!".

"Not this time," I replied, kissing her neck "but never say never again..."
