My wife and I were in bed, naked. It was Saturday night, and I was ready for our weekly round of mediocre sex. After fifteen years of marriage, the lovemaking had gotten pretty routine. But still, sex is sex.
I rolled on my side to face her. "Honey?" I said expectantly.
She remained on her back, staring at the ceiling. She spoke, in a monotone. "I've been unfaithful to you."
"What?" I was dumbstruck. I wasn't even sure I'd heard her correctly. "What? When? With whom?"
She kept staring at the ceiling, and spoke in a calm, flat voice. "It was with your brother. We've been sort of flirting with each other for a long time when you weren't looking. We happened to be alone together the other day when he came by to drop off your tools. It just sort of happened. First we were in each others' arms, kissing passionately; you know, like you and I used to do. Then his hands were all over me; groping my breasts, squeezing my ass, and he started fingering my pussy through my skirt. I could feel his cock through his trousers. It felt huge. That was all it took. I dragged him into the bedroom."
"This bedroom? You did it right here? In our bed?"
"Yes, right on this very bed. We stripped each other naked. I had to see that huge cock. It was immense. Much bigger than yours. I wanted to suck it, but it was too damn big. I could barely get my mouth around the head."
Lying there next to her, I felt the blood rising in my cheeks. I was so humiliated by her infidelity, and worse yet, by her total lack of shame over it. Her matter-of-fact voice and her staring eyes made me think that she was actually proud of herself!
"I wrapped both my hands around it," she continued. "My fingers didn't even meet, that's how thick it was. I jacked his shaft up and down while I tried to get the head into my mouth. Eventually I gave up on that, and just licked around the rim while I kept jacking him. I slurped the head like an ice cream cone. I even stuck my tongue into his pee slit. It was so wide open, it was easy."
Through my shame, I actually felt my cock swell a little as she spoke. It twitched as I thought of my wife's mouth, stretched to the limit trying to swallow my brother's cock head.
"He got tired of my licks on his cock, and he made me lie on my back. His cock was dripping tons of pre-cum, and my pussy was wetter than it's ever been. I spread my legs -- just like I'm doing now -- and waited for him to enter me. His cock came at me like a torpedo; it looked even bigger than ever. I thought he might split me in half, but I didn't care. I was so tired of your puny little dick that I was willing to die to be fucked by a real cock."
My penis twitched again, picturing my wife's pussy being split by my brother's enormous, dripping, throbbing cock. Her hand had crept to her crotch and she was rubbing herself.
