Sister in law wants to watch

My wife and I were visiting her sister and husband at their condo in Florida. We were on vacation but the in-laws still had to work. One morning just after they both left for work we decided to take advantage of being alone and started fucking. We ended up with her on top of me, her back to my chest while I fucked her ass. We hadn't been in the position very long when I look up and saw my sister in law standing in the doorway watching us fuck. My wife's head was laid back so she couldn't see and I didn't say anything. Our feet were towards the door so she had a perfect view of my wife's pussy and my dick pumping her ass. She just stood there watching and I was so close to cumming I couldn't stop.

Just as I was ready to cum I pulled my dick from my wife's ass, stroked it a few times and blew my load all over my wife's pussy and stomach. When I finished cumming my sister in law left and my wife never knew she was there.

Later that evening.

"Why didn't you tell me my sister was watching us fuck?" My wife asked later that evening. "I didn't want things to get weird" I responded.

"Well, it is weird but she told me all about it.

"What did she say?" I asked.

"She said it made her pussy gush like a faucet and that she sat in her car and fucked herself to a raging orgasm. Oh, and she wants to watch us again. "

"Seriously?" I asked. "What did you say?"

"I was noncommittal but I have to say it kinda turns me on. And I can see by your massive hard on that it turns you on too."

"Yeah, I say we let her watch"

"Me too." My wife says. "But in the meantime why don't you lick up this juice running from my cunt.

So my wife and her sister arranged for her to come home from work early the next day so she could watch us fuck before her husband got home. There was only one rules; she had to be naked.

When she got home we all got undressed and went into their bedroom. My wife and I got on the bed and started making out and touching each other all over.

Finally my wife slid down the bed, got on her hands and knees and sucked on my cock. SIL wanders around the room to get the best vantage point, which was usually someplace she could see her sisters ass and pussy.

Before I blew my load from my wife's sucking I flipped her on her back, got between her legs, rolled her legs up towards her head and started eating her ass.

By this time SIL was sitting on the bed next to my wife's head, one hand spreading her pussy lips apart the other rubbing her clit and frantically sliding three fingers deep into her pussy while she watched me eat her sisters ass.

At this point my wife reached over and started to finger fuck her sister. First with just two fingers. She kept adding fingers until she was fucking her with her whole fist. My wife then reached back with her other hand and started to finger fuck her ass.

I worked my way up eat to my wife's pussy while I coated two fingers with her juice and slowly worked them into her ass. My wife continuing to fist her sisters cunt and finger fuck her ass.

I put a third finger in my wife's ass which put her over the edge and she came all over my face. At the same moment I heard SIL moan as she came hard squirting my wife's face.

I licked up as much of my wife's cum as I could then slid up onto my knees and jammed my cock deep into her pussy and started fucking. After a few strokes I heard SIL whisper "fuck her in the ass" as she slid onto her sisters and slid her asshole up and down my wife's face. I slid my cock from her pussy and planted it balls deep in her ass and fucked her hard.

As my wife approached another orgasm she whispered to her sister between moans "do you want to watch him cum?" SIL responded that she wanted to see me cum on her sisters face.

This was too much for me and I took my cock from my wife's ass and crawled up to her head as both women orgasmed again I shot my load covering wife's face and her sisters pussy with cum.

We lay there catching our breath for a while before the sisters got up to talk about what just happened.

Me, I lay there thinking this was only day 2 of vacation. It's going to be a good week
