I know it's totally wrong, but I simply cannot help myself, not that I now know just how big his cock is.
My father in law Terry, has the early stages of dementia, so he's come to live with us. Late last month I caught him wanking in our lounge watching a soft porn film on tv late at night. My husband was sound asleep in bed as I walked in on Terry. So when he saw me enter the room, but carry on wanking what I saw to be a massive cock, I couldn't help myself. I walked over to him took his cock into my right hand and masturbated it for him. All the time he kept on calling me Louise (His deceased wife's name) When he began to feel my breasts through my top, I bent down an took his leaking cock ito my mouth. For the next five minutes I had Terry's cock sliding over my tongue. By that time my pussy was soaking wet with sexual need.

Making Terry lay back I stripped, got on top of him and mounted his dick. It was the best fucking I've ever had and that's saying something, as I've had over twenty different men, other than my husband. It genuinely was fantastic sex and I rode him for all I was worth. His cock didn't soften either once he'd cum up my pussy, so I had Terry fuck me doggie as I lay over the arm of the sofa. The orgasm I had as his cock pounded my pussy was so amazing, I screamed out loud.

Cleaning us both up, I asked him not to say anything as his son came downstairs to see what the noise was. Terry told his son he'd scared me by popping out from behind the kitchen door. Funnily as he smacked my butt, before I followed my husband back up to bed, Terry said "Thanks Louise". I've been Louise five more times since and each time I get Terry to do more and more sexual things to me. I don't think he remembers, but only last week as we'd fucked, Terry actually said my name as he was forcing his cock up my ass. He also said it again when he wanted his cock sucking this morning.
It is wrong of me, but if you saw just gorgeously big Terry's cock is, you might think of me as just lucky.
