Father In Law

Since I married his son, my father in law Russel has been hinting at sex.
I know for certain he has a huge penis, because I've watched him masturbate. And he knew I was watching.
He stayed over with us for a few days, and needing a glass of water during the night, I went downstairs.
He was masturbating on our couch when I walked past the lounge.

He knew I was watching, but didn't stop stroking his massive cock. I genuinely didn't mean to, but I couldn't stop looking and found myself touching my pussy through my knickers.

I'm sure he saw me and began saying my name as he tossed himself off faster and faster.
When he came, I swear my heart jumped and I had an orgasm.

Giving up on getting a drink, I went back to bed and quietly lay next to my husband.
He stirred and turned to me putting his hand between my legs. A minute later Russels son was tonguing my pussy and clit, while I couldn't stop thinking of my husband's fathers cock.

We fucked until I rode my husband's cock, making us both orgasm. But in my head all I could think about, was wanting Russel to fuck me.
Nothing happened between myself and my father in law, although he did give me a knowing wink the following morning.

The main reason I'm here, is Russell will be staying with us again soon. And during his four night stay, his son will be working away on two of the nights.
I'm not sure if Russel flaunts his cock again, I will be able to resist. I've even begun dreaming of him fucking my mouth, pussy and arsehole.
