The holidays were approaching and my wife asked if her sister could come over for dinner. It had been over a month since she had visited. Sara was my wife's younger sister who had just recently graduated college and moved to our neighborhood. She was a great girl who was always helping out. Unfortunately she began to think our home was her home and she began to get on my nerves! But it had been a while so I said of course.
A week later we were all having dinner, as we sat around the supper table and caught up, I found myself staring at Sara's very cute body. She was just 5'3" and couldn't have weighed more than 110 lbs. I have never been attracted to her in the past and perhaps it was just the second bottle of wine speaking, but in either case she looked hot tonight. We all continued to chat and drink and drink some more. We went into the living room and listened to music and continued having a great evening. I think the wine was going to my head because I found myself stealing glimpses of Sara more frequently, her butt was firm and when she bent over I was able to see just the top of her G-string panties. At 10:30 just about when Sara should be headed out the door, my wife told me that I needed to be punished for starring at Sara tonight. I laughed nervously, my wife had never mentioned punishment ever before in the nine years we had been happily married? Not to mention feeling like a fool in front of Sara. I was surprised and quickly offered what must have sounded like a very weak excuse. I wasn't looking at your sister's butt. Sara jumped in and said that she had seen me looking at her behind and that she would be able to help with any punishment that was due. I laughed again, Sara is a pretty naive girl, I really didn't think she was up for doling out any punishment. What was she doing? Punishment what are they talking about! Sara again said, don't worry I can do it in 45 minutes on the nose, she looked at my wife who nodded in approval.
Sara said she would punish me but only if I understood this was just going to be a 45 minute punishment, and there was to be no backing out. I looked at my wife and she just nodded. I have to admit this was very odd, never ever has anything like this ever happened. I just lead a normal life, happily married, with no punishment of any kind in the past. Sara jumped up and said she would be right back, she quickly left the room. I clearly had no idea what I had gotten myself in to. Punishment? What was going to happen? I began to think maybe this was actually going to be fun. Maybe a few swats on the backside, or maybe just Sara and my wife had planned a threesome!
She returned with a duffle bag, and pulled out a timer, she set it for 45 minutes and pressed start, it beeped. Cool I thought the timer has already begun how bad can it be? She is such a cute girl, and when she walked over to me I thought this might actually be really fun...who knows maybe tonight is when I will get to see Sara naked! She asked me to stand up and come over to the chair. I did as I was told. As I walked across the room I noticed my wife had a really funny smirk on her face, she must have known of what was to come...? Sara asked me to bend over the chair, it was a very high back chair so I was leaning over just slightly. She pulled a long scarf from the bag and began to tie my hands in front of me, she almost looked like she knew what she was doing? She tied the scarf around my hands and finally over the back and onto the legs of the chair, and a few minutes later she announced she had finished.
I was standing there bound to a chair with my wife and sister-in-law in my living room, how weird. The scarf was not extremely tight, but I definitely knew I was not supposed to be able to get free without some help. Sara and my wife giggled and left the room, Sara said some coffee might be nice. This was strange, the timer read 39 minutes, how much could they accomplish especially if they were walking away? .......just then Sara announced she had forgot something, she walked back into the room walked up behind me and whispered in my ear "now the fun begins." She reached around the front of my pants unbuttoned them, quickly slid her fingers in the waistband of my pants and underwear and slid them down to my ankles! I was nude! And Sara was looking at my ass. I was so embarrassed I almost died, I felt the cool air rush over my skin, my balls retreated with the cold and I realized this was going to be very scary. Sara touched my back with her warm hands and ran her fingers down to my bottom, she laughed very quietly and said your wife doesn't even know I've seen you naked yet, she paused and said how does it feel to be nude in front of me? I Was mortified. I'll be back in just a few, And then she left the room. I heard them making coffee, and still could not believe I was naked! Sara had seen my bum, and probably more!
What was my wife going to say? Did she know I was going to be naked when she entered the room? Did she know that Sara had planned to see me nude? I suppose I could have untied myself but was this part of the plan, would I have gotten in more trouble? Perhaps Sara had gone too far, maybe my wife would be angry I don't know? Well it didn't matter now because it was too late They both just stepped back into the room! My wife gasped at first but then just stood there quietly. Sara jumped in and said come on time to let the punishment begin. I was so embarrassed. My face must have been red as a beet. Sara walked over to me and swatted my ass, it stung a bit but it was really just the feeling of another woman touching my bare skin that felt weird. She reached into the canvas duffel bag and puled out a tube, it looked like a toothbrush holder. She then walked behind me and I heard a beep. It was not the timer, that was sitting in front of me counting down...and not fast enough. My wife giggled and said I can't believe it, Sara then said it was time to take my temperature!! Oh she must be kidding...my temperature this is nuts. Sara then leaned in and told me that this was probably going to cause me to get hard! I almost fainted.. She slowly separated my ass cheeks, but I was so focused on what she had just said about getting hard. She must have known what she was doing because the more I tried not to get hard the harder I was getting. She took her finger and slowly massaged my anus, my dick grew harder, she must of had some Vaseline on her finger because before I knew it she was penetrating my ass. She wiggled her tiny finger slowly in and out and she whispered in my I ear I told you your were going to get hard. She was right!! after just a few teasing strokes I was at full attention, my cock was on display and Sara must have been happy as can be! What was my wife thinking, was she pleased or pissed or was she enjoying this? Sara then took the thermometer and slid it ever so gently in my ass and pressed the start button.... I was dying, I looked at the timer we still had 21 minutes to go, was it going to get worse?...if I only knew.
