I’d been living with my girlfriend Ann for a couple of years. We had a nice two bed flat in a converted Victorian house in a trendy part of town near to the local university. Ann had a sister, two years younger aged 22 named Emma. Emma had been living with her parents but had just got a place at our university. Rather than rent a place or move into halls of residence, Ann suggested that Emma could stay with us in our spare room for the first year of her studies.
I was fairly relaxed about the idea as I got on well with Emma and she was very easy on the eye. Despite being sisters they were nothing alike physically. Ann was brunette about five-foot-seven tall and a size 12, whereas Emma was a petite blond five-foot-two tall and just a size 10.
Anyway, Emma moved in and things continued generally as normal other than there was sometimes a queue for the one bathroom and there were more discarded clothes strewn around the flat. Untidiness was something both sisters did share in common. It seemed almost every day I found discarded items laying around including some very skimpy erotic lingerie which Emma seemed to like wearing.
I did wonder if having Emma in the spare room next to our bedroom would curtail some of Ann’s bedroom behaviour. The wall between the two rooms stopped short of the ceiling to allow some borrowed light from our room which was naturally lit, into the second room, which didn’t have its own window. Whilst this allowed a good amount of light, it also meant you could hear everything in each room.
Ann was very vocal when we had sex, beyond the average gasps and groans, often demanding that I 'fuck her harder', or 'shoot my cum deep inside her’. I very much enjoyed talking dirty during sex, but now that Emma could hear everything I thought Ann might be more subdued. But it seemed the opposite was true and Ann seemed to be even louder when she knew Emma was in her room.
Ann was also quite submissive and I would often spank her, especially when fucking her from behind. I loved to land a flurry of hard spanks to her bum just before I came. Ann would always encourage me to spank her harder and make her ass red.
So we continued fucking as normal, even though Emma could hear our every move, especially when I spanked Ann. I’m sure Emma was getting turned on listening in to us as I could often hear little gasps and the rustle of bedclothes after Ann and I had stopped fucking. Nothing was ever said between us, even though we both knew we were listening to each other.
I knew Emma had a new boyfriend called Gary and we’d been out together as a foursome a couple of times. I thought he was a bit old for her and a bit stuck up, but she seemed to like him and began spending more time at his place, certainly on the weekends.
Then one-day Emma asked if Gary could stay over for the weekend because the heating had broken in his house and it was freezing. Ann and I were going away to a wedding and would be staying for the weekend so I said yes and told her to enjoy herself!
We left early on the Saturday, so we missed Gary arriving. The wedding and reception were great, and on the Sunday Ann accepted the offer from an old schoolmate, who was also at the wedding to stay on and go shopping with her. The schoolmate had offered to drop Ann home after shopping, so it meant I could miss the shopping and get home first.
I got home about 3 pm, there was no sign of Gary or Emma, but I shouted hello anyway in case they were both in her room. I then began to unpack, lost in my own world until I heard a quiet moan and a little gasp. This was then followed up by the unmistakable sounds of a bed creaking quietly. That was why there was no sign of them, they were in bed fucking. I stopped unpacking and listened to them fucking which got louder and louder as they both neared climax. Gary clearly seemed to know what he was doing as he kept Emma gasping for about half an hour before he finally came. After that I heard him saying he was off to his flat to check on the heating, then the front door opened and slammed shut as he left.
Shortly after that, I heard a scream and Emma came running from her room shouting there was a spider in the room and she wanted me to get rid of it! I wandered into her room and scooped up the spider and threw it out of the front window while Emma stood in the kitchen with her back against the wall. It was clear she didn’t like spiders!
I told her it was all clear but Emma insisted I come into her room and check it was all clear with her. I was willing to oblige if it made her happy. I did a quick sweep of the room and there were no more spiders. There was however clear evidence of their recent fucking with the unmade state of the bed and what looked to be a cane half covered by the duvet. I had missed that when I first removed the spider, but now I pulled it out from the covers and asked Emma what she used it for?
Emma blushed and stumblingly said it was something that Gary had brought and I could guess was he did with it, especially with the way I spanked Ann. So, she had definitely heard me spanking Ann during sex. I smiled at her and said I had a good idea, but maybe she should tell me. Emma gave me a crooked grin and said rather than tell me, she would show me. With that, she turned around and slipped down her jeans and bent over the edge of the bed. I could now see her bum was clearly marked with six violet welts from the cane. Emma turned her head and said Gary had caned her on Saturday night, he’d given her three with her knickers on and then three on the bare, after which they’d fucked.
I asked her to tell me more and Emma said that the first three stokes were hard, but the next three with no knickers had been real stingers. I was surprised that the three strokes on the bare were worse given that Emma always wore such skimpy knickers that would afford such scant protection. Emma said she thought it was more about the fact she was bent over, with her knickers around her knees that made Gary cane harder - a point I could fully appreciate. She said Gary caned her often and always hard, which Emma admitted she struggled to manage sometimes, especially when he gave her twelve or even eighteen strokes.
Emma said that after the caning Gary had first taken her from behind and then she had ridden him until they both had come a second time. Then, in the middle of the night, they had both awoken and Gary had fucked her again, this time in the missionary position. I was amazed at how open Emma was with what she’d been up to last night and her telling me all this whilst bent over the bed was very erotic. I asked if she’d tried anal, but she replied that Gary was very well hung and she found it hard to take him, so they didn’t do it very often. She also said it was hard to suck him as well as he liked to face fuck her which just made her gag. Gary would make her put on her glasses and then she would have to suck him until he shot his load on her face, hair, and glasses.
I moved closer to her so I could feel the welts from the cane and generally caress her from behind. I could feel that she was very damp between her legs and I carefully eased her knickers to one side to allow me to slip a finger into her. I’m sure I could feel some of Gary’s cum still in her. She gasped moved and gently pushed back onto my probing hand.
Emma then went on to say that earlier that morning Gary had suggested they fuck in our bed. Emma said she had been against the idea, but Gary persuaded her and they had fucked with Emma laying on the end of our bed and Gary standing on the floor. This was one of the positions Ann and I favoured as it allowed you to see each other fucking in the long mirror on the dressing table. Clearly Gary and I shared the same tastes! They hadn’t finished in this position as Gary had wanted to do Emma from behind so he could spank her on her caned bottom as he came, which he did, bringing them both to a very satisfying climax. Emma said I had then probably heard fucking again this afternoon as I had come home as they were in mid-fuck.
