The fourth picture took me by total surprise.

Jess was standing fully naked in what looked like a hotel hallway. She was rubbing her pussy with one hand and pointing to the room number - 204 - on the door with the other. The look on her face was of sheer lust and hunger. It took a stunned moment for me to to click to the meaning and hope I was right. In that moment a text came through. “Hotel directly across the road. Run”.

I didn’t bother finishing my drink. I was up, out and across the road in a flash. The hotel was a very cool refurbished old building. A quirky, arty boutique hotel and with a confident wave to the receptionist I bounded up the stairs in case the elevator had swipe card access control. I got to the second floor and went along the corridor until I found 204. It was thrilling to think my wife had been standing here naked just moments before.

The door looked closed, but on closer inspection there was a piece of plastic showing, stopping the door lock from closing fully. As I pushed on the door gently, a condom wrapper fell to the floor. I kept pushing the door open, stepped inside and closed the door behind me. I looked down a corridor towards the window at the end of the room but otherwise saw nothing. However, the sounds were unmistakeable. Bodies slapping together and I immediately recognised the moans of my wife.

Walking slowly down the hall a short way, past a kitchenette and wardrobe on one side and the bathroom on the other, I got to the corner of the hall, opening onto the room. All the time I could heard flesh slapping and Jess moaning. At the opening to the room I just stopped and stood, and watched.

Jess was on her hands and knees on the bed facing me. The man from the pub - Jess told me his name was Owen later - was behind her, fucking her from behind. Jess's eyes were closed. Her mouth was open, moaning. Her tits were swinging with each thrust.

I undressed quickly. Moving towards her I leaned down to kiss her. Jess opened her eyes and smiled at me sexily. We kissed briefly, passionately as she moaned into my mouth with each thrust.  It was so hot being with her with another guy, enjoying her pleasure with her made it even sexier.

She reached out and grabbed my cock, pulling it towards her. She opened her mouth, and as I stood, she hungrily took my cock in her mouth. Moaning even more as she licked and sucked. She pushed herself hard on Owen's cock and then lunged forward to take as much of me in her mouth as she could. It was amazing to watch her throw herself into it.  I saw Owen reach around and under her and I knew he was playing with her clit by the way her moans intensified. I reached down around her too - cupping her delicious tits in my hands, playing with her nipples.  I could feel her moans vibrating on my shaft and when she looked up at me, into my eyes with that look of pure lust and pleasure I almost exploded in her mouth.

Pulling out of her mouth I motioned for her to turn around. She pivoted on her knees and very quickly her ass and pussy were facing me. Own took his condom off and she devoured his cock with as much enthusiasm as she’d just been using on mine.

Before I entered her I enjoyed the view of her from behind, her knees splayed wide and her ass high, her pussy glistening and puffy. She moved one hand between her legs as Owen held her head, fucking my wife's mouth rhythmically. Stroking myself I watched her slide a finger up and down the length of her pussy a few times, before focussing on her sensitive clit. I pushed two fingers into her pussy, before leaning down to lick her ass, circling her tight opening with my tongue. As I applied a bit of pressure with the tip of my tongue I felt her ass tense and relax, and felt her pussy grip and then release my fingers. I knew her climax was coming.

I repositioned myself behind her and fingered her ass gently, not pushing into her, just circling and then applying pressure at the opening like I know she likes. She was still playing with her clit as I pushed into her slick and hot pussy. I heard her moan loudly and she pushed back on me. I felt her fingers working on her clit as I fucked her hard from behind and soon I felt her pussy spasm and clench around my cock. She dropped Owen's cock out of her mouth as she let out a loud moan, coming hard. I kept pounding into her from behind as she came in waves.

Owen stroked himself and I saw the first spurt of come hit Jess's cheek. Seeing this, and then seeing him send a few more streams of come onto Jess's tits as he came loudly sent me over the edge. Grabbing Jess's hips I buried my cock as far inside her as I could, and enjoyed the feeling of coming deep inside her.

As my climax subsided Jess pulled away from me and quickly rolled onto her back. No sooner had she opened her legs, Owen was between her legs and lapping at her pussy. I watched as Owen licked her pussy  furiously. “This was his idea” Jess said slightly breathlessly, but smiling. Owen cleaned up Jess's pussy as Jess motioned for me to kneel beside her. She pulled my cock to her mouth, and started licking and sucking me as I watched Owen going down on Jess.

In no time I was hard again and I could tell Jess was building to another wave of pleasure. “We should finish this at home” Jess said pulling my cock from her mouth and kissing the sensitive tip gently.

Owen clearly knew this was how things would end and moved away from the bed as we dressed. He wrapped a towel around himself and gave Jess a hug and a kiss on the cheek, and slapped me on the shoulder as we went past him to leave.

We dashed down the stairs and onto the street giggling like naughty teenagers, as we headed towards the taxi rank.  In the taxi Jess snuggled into me whispering in my ear. “You we’re right.” she admitted quietly. “It’s so hot having you with me when I’m fucking someone else. Both of you fucking me at the same time. Seeing how much you were enjoying it made me enjoy it even more. It’s like me and you using a sex toy together that happens to be a man” she laughed. She stroked my crotch as I slipped a hand up her skirt finding her pussy slick with juices and new desire.

“Next time I want you to find me a man to fuck, or maybe two.” she said huskily looking into my eyes. The taxi driver shifted in his seat and I saw him looking at us in the rear view mirror. We ignored him as we kissed and touched each other all the way home, hot with arousal and excited anticipation, knowing we'd have some our hottest sex ever tonight and that it would only get hotter from here.
