I didn't choose the situation I found myself in. It was thrust on me or more to the point, into me. My husband Darren wanted the threesome, he chose a friend he knew with a much larger cock than his own. And he was the one who insisted I take Marks cock anally. In the three hours Mark spent with us, I became fixated with his huge cock and I could tell Darren was getting jealous. By the end of the evening Mark had fucked me all over our house and in every conceivable position. Taking all nine inches of his cock hard up my asshole was the absolute highlight for me and it was during his deep thrusting up my ass I came like never before. Darren was quick to start calling me a slut as my asshole trembled, making me cum hard on Marks cock as I sank down time after time onto his full length.

I told Darren that was it. It was only going to be that one time. But I knew as I passed Mark my phone number I was already looking forward to the next time I took his cock deep inside my body. Darrens job has enabled us to meet on several occasions since and each time Mark teaches me how to satisfy him and myself in every way.
Darren shouldn't have started what he couldn't take, now I take all I can handle from Mark and his wonderfully large cock.
