My Wifes Mother

My MIL, lets call her Sue asked me to help with painting the spare room whilst her husband was in hospital. He had major heart surgery and was in for 5 weeks so Sue had been getting no action. On day three I turned up early and let myself in with the spare key. As I went in the kitchen I heard the unmistakeable buzzing sound coming from the bedroom. I gently opened the door to be greeted by a view of Sue on all fours with the biggest dildo I have ever seen!!!
I silently unzipped and started to stroke, Sue was totally engrossed in her own actions and was moaning loudly, I stroked with fury and felt my balls start to tighten, at that exact moment Sue screamed "Oh Lewis fuck me deep" as she plunged the huge toy in fully. SHE was frigging herself thinking of me!!! I couldn't believe my luck. I cleared my throat loudly whilst holding my solid member upright for Sue to see in all its glory. I wish I could say we got to go further but the moment Sue looked at me as I shot my load so hard, it went all over the floor and reached her bed too.
Needless to say there are lots more details to follow but not for this site I'm afraid!!
