I was clearing up the house after the previous nights party. I had finished downstairs and was finishing the bathroom when a naked woman walked straight in and sat down and had a pee. Then she was up and after a wipe was back into one of my spare rooms. I had now finished the bathroom and was making my way towards the first bedroom when the woman now dressed came out and after saying thanks left the house. I stripped the bed removing two used condoms and several empty beer cams and an empty vodka bottle. Then I tidied my bedroom and was on to the last bedroom. The bed looked a mess as if someone had scrunched the bedding up into a heap. I went to pull it off and something pulled back. I teased the quilt and blanket away to find a young woman naked still in the bed. I had no idea who she was or who she came with, when she said," fuck me again." Her eyes were tight shut. Obviously she thought I was someone else. My cock was twitching at the very thought of fucking this delightful young lady. "Hurry up," she insisted. So I stripped off and slipped in behind her. My cock was between her arse cheeks and her hand came between her legs and steered it towards her pussy. Then she heaved herself back onto my cock. It slipped in up to my balls. She groaned and started to rock herself on my cock. I was pushing back and my groin was slapping against her arse making a slapping sound with each thrust. Then she was coming and her pussy was gripping my cock as she came. I kept on banging into her although she was now laying still. Then she was again picking up the rhythm again and then we were both coming. I cuddled up to her stroking her tits as we rested from our efforts. Then she turned over to face me. Imagine her surprise to find I was not who she thought I was. "Who the fuck are you?" she asked startled by not knowing me. I told her it was my party she had been at. Then her hand was between us grabbing and stroking my now limp cock. As she stroked she asked where Mel was. I told her I had seen him go home about midnight. Then she asked who had been fucking her in the early hours of the morning. I told her that I had no idea. Then she giggled and said, " Two mystery cocks in just a few hours," then she dipped under the duvet and started to suck my cock. I turned around and was sucking and licking her pussy as she sucked my cock. The young lady was groaning and gasping with my cock in her mouth. Then she pulled away and moved onto her hands and knees. "Fuck me, please fuck me," she pleaded. I was quickly up on my knees behind her and ready to fuck her again. She gasped then groaned as my cock filled her pussy again. She was the most active person I had ever fucked as she thrust at my cock harder than I was fucking her pussy. I could feel my cock getting ready to blast another load of cum into her pussy. "Yes, yes, yes, deeper, harder, don't stop. Arrrrgh," then she came and her pussy miked the cum from my cock. We collapsed into a heap of body parts. As I recovered I asked who she was. She informed me that she was Claire, Mel's wife. We cuddled and kissed. I asked what Mel would think of me fucking his wife. She told me that she didn't give a fuck what he thought as he had left her here and was probably fucking some bimbo. Then she giggled and asked if I was able to fuck her again. I told her not for some time. We ended up in the shower soaping each others and I was sucking her gorgeous tits. She was a little annoyed when she saw that whoever had fucked her in the early hours had left a hickey on her tits. I told her I would kiss them better. and sucked one into my mouth. She insisted that they must be treated the same, so I started to suck the other tit. Claire was now moaning again and pushed me down to her pussy. I licked and suck her pussy as she gripped me by my ears. Then I felt her shake as she came again. I was hard again and as I stood, I lifted one of her legs and steered my cock back into her pussy. Claire moaned and then told me to fuck her until she came again. I did as requested and filled her pussy with more cum as I reached my climax at the same time as she reached hers. After finishing up in the shower I dried her as she dried me. We had just finished dressing when the doorbell rang. I answered it. There stood Mel. "Is my missus still here," he asked. I told him there was a young lady just getting up from the sounds of things. "Don't tell her that I wasn't here," he asked, "I don't want her to find out that I went of with Shirley. Man that Shirley is one good fuck. She had fell asleep in her drunken state so I thought that I could get away with seeing Shirley. Don't tell her please." I told him that it was not up to me to tell his wife tales. He thanked me. Then Claire came down from upstairs, fully dressed and looking fully refreshed. "Hi honey I wondered where you had gone," she told Mel. He told her he had slept on the couch so she could have a good sleep. As they left Claire winked at me. The following day she rang me and thanked me for not dobbing her in and that she would be around on Wednesday night. We have had an affair ever since and hope to resume it when the latest lock down restrictions end.
