[M] Naked in front of my SIL for the first time

The wife’s sister popped over one day in the summer a few years ago and ended up staying for dinner and then some drinks after. By the time we had polished off all the drink in the house, my wife was passed out on the sofa and her sister was well over the limit to drive home.

Her kids were staying with their dad for the weekend and all my kids were out for the night somewhere or another so I said she could stay in my daughters room. I went up and checked there were covers on the bed a dug out a clean towel in case she wanted a shower in the morning. As I left the room she was at the top of the stairs and we bid each other a good night. She went in and closed the door.

I went to my room and undressed for bed. I sleep naked and after dumping my clothes in the laundry basket walked around the bed to get in on my side. At this point SIL come out of her room and got a full view of my middle-aged manhood.

She is the same age as me and we have known each other longer than I have known my wife but never been together. She has an attractive face and very curvy with huge breasts and big ass. If I could get away with it, I wouldn’t say no, but giving the circumstances she is out of bounds.

She was silhouetted as she left the bedroom. I could see she was wearing her blouse but couldn’t tell what was below.

She apologized for seeing me, I was fully lit in my bedroom light, and she headed to the bathroom. I heard the door close so nipped downstairs to get the wife to come to bed. I couldn’t get her to wake so covered her up with a throw from the back of the sofa and headed back to my bedroom.

Just as I got to the top of the stairs, the bathroom door opened. If I had wanted it to happen, I could never have got the timing that perfect if I tried.

In the bathroom light I could see she still had her knickers on. They were lacy things and virtually transparent. Her pubes were visibly squashed behind the thin vail and black curls of hair spread out the sides of the triangular panel.

This time I apologized to her for looking as I felt I had been gazing for far too long. She ignored it along with the fact I was right in front of her still very naked. She asked about my wife. I explained she wasn’t going anywhere for the time being. We chatted for a bit giving me time to notice her blouse was only half done up. She was no longer wearing her bra and her nips were making prominent pokes at the thin material which was straining between the 3 remaining buttons that were fastened. I could even see the bumpy areola impressions spreading around her nipples the size of saucers.

We were in each other’s way and had to pass each other at the top of the stairs. It wasn’t until we said good night to each other again and passed each other I realized the little man had perked up. Only a lazy lob, but enough for it to be pointing forwards. Just enough so that when we slid past each other it grazed her thick thigh.

She looked down and said my wife had told her I was a grower.

I apologized again and we went our separate ways. I couldn’t help but watch her bubble ass wobble away from me. Her gusset was nowhere to be seen between her butt cheeks. Only a small triangle of fabric emerged from her butt cleavage which attached to a thin band around her waist.

It wasn’t until I was in bed I wished I had told her it wasn’t at full mast yet. I didn’t want her thinking that was it! The moment had gone.

PS. Yes I did immediately bash one out at the thought of her looking at me.

Stay tuned for the following day when she did see my full erection.
