Shower scene

[crassy]

Its christmas and as usual we had family over to stay. Anyway the shops had re-opened and the wife had to go back to work but the sister in law wasn't going home until later. I excused myself and said that I wa going to take a shower and wouldn't be long.

I undressed and got into the shower and didn't realise the door had opened slightly. I started toshave my balls as usual and this always gets me hard when I glanced up and through the open door could see the sister in law watching.

I pretended that I hadnt seen her and started to wank myself off. At the sight of this the sister in law started to undress and lay on my bed before starting to finger herslf daft. I couldnt wait any longer nad stepped out of the shower and walked across to the bed my cock still in my hand. The sister in law said what kept you and beckoned me over . Within seconds I was inside her and as I was about to cum tried to pul out. She stopped me and said it was okay. I shot my load and she finished me off wit her mouth and then without a word got up got dressed and left the room.
