Want to confess. I've recently been caught by my wife's younger sister jerking off into her panties. My wife's sister has been staying with us for about a month after she and her fiancé split up and she had to move out of their flat. I've always liked her when she's come to stay for weekends and holidays in the past but this is the first time she's been in the house for anything longer than a few days. Needless to say she's got quite comfortable and will often walk round in shorts and t shirts that are very revealing. It had lead to me jerking off much more than usual and fucking my wife a lot more than we did before her sister moved in (I'm guessing my wife has probably guessed why I'm always fucking her so much now and why im screwing her so hard, thinking of her sister when I do it, but hasn't said anything as she seems to enjoy getting more sex)
It started the other week when I was downstairs in the living room with my wife, her sister had been down in her skimpy pyjamas and after she had gone to bed my wife had noticed that I had a hard on (caused by her little sister of cours) and for the first time in ages without saying anything she pulled my pants down and started to suck me. I've made appoint of being quite loud when we have sex hoping her sister might hear, on this night I was enjoying the blowjob and one thing led to another and I had my wife on all fours fucking her as hard as I could. During the sex I turned around and noticed my wife's sister was watching at the door. I kept fucking and moved my wife round so that she still couldn't see the door but so that her sister could see my cock sliding in and out of my wife. Her sister watched as I fucked my wife and just so she could see me cum instead of leaving it in I pulled out and jerked my self over my wife's arse as I was cumming. Her sister watched the whole thing.
Since then I've been trying to walk round in as skimpy as underwear as I can and have even walked around the house naked when my wife was out and her sister was in. I know she's seen me naked around the house a couple of times and she always stares as I give her as much chance as possible to see my cock and balls.
The other day I thought she and my wife were out and so I snuck into my wife's sisters room and found her dirty laundry, I dropped my pants and started jerking off as I sniffed and licked her worn panties. I was really going for it standing over her bed stroking my cock hard and rubbing her panties all over myself when I suddenly realised my wife's sister was standing at the door. She must have got back early and I was so engrossed I dint hear her come in. (Just glad it wasn't my wife) I panicked and pulled my pants up and dropped her knickers ready to leave her room but she just stood and stared at me not saying anything. I didn't dare move, hen I noticed she started looking down at my hard dick that was still visible through my pants. She just stared. After a few more seconds I put my hand down and started to rub my self, my wife's sister just kept staring and not saying anything, after a few minute where she just stared and smiled as I rubbed I felt brave and dropped my pants and began to stroke myself in front of her. She came into the room and knelt down in front of me with her eyes at the level of my erection as I kept stroking it. As I was stroking I picked up the panties I had before and wrapped them round my cock as I wanked. I stroked for ages with her watching my thick veiny shaft, eventually as I came I covered her knickers but I came so hard some shot out and went on the jeans she was wearing kneeling in front of me.
I left and nothing more has been said but I'm sure she is staring more and I've even heard her moaning loudly as she masturbates in bed at night. What do people think should I try and take it further and find a way to give he my cock to help her frustration and mine or just keep looking for opportunities to let her watch me with nothing else happening?
