around 6 months ago I fell and broke my arm and finished up with a plaster cast from wrist to elbow and as it was my right arm and I am right handed...it was a real pain.
It was real awkward doing things especially getting dressed, you know buttons and things. A few days after getting the cast on I was in bed when my sister annie who is 18 came in to see me. She asked how my arm felt and I replied it was not too bad. She said it must be awkward being right handed and I said it was.
She said especially 'pulling it'... I said nothing but she said i'ts ok I know you do it, I asked how she knew and she said she had heard me moaning one night and had peeked in. I had my eyes closed but since the bed covers were going up and down she knew what I was doing.
She asked me if I was able to pull it and I said no so she asked me if I would like her to do it for me. I was a bit shocked as nothing had ever happened between us before, and asked if she knew how to and she said she had done it for her boyfriend so I said ok.
She pulled the sheets back and after getting some tissues pulled my pyjama pants down to my knees, she then started stroking my balls and prick and soon it started to stiffen and was soon fully erect, 6 1/2 inches uncut. She licked her hand and when I asked what she was doing she replied it was lubrication. She then gripped my prick and started pumping my foreskin up and down. A few minutes later I was ready to cum so she got the tissues ready and I shot a stream of cum into it.
She cleaned my prick and pulled my pyjamas back up. She asked how it felt and I replied it was great and thank you. She said your welcome and anytime you need it just ask, a real helping hand when I needed it.
