Me and my Mother, a long held dream come true, part 2: Claire joins in.

Fucking my Mum, Part 2: Sister.

Much to my surprise more than anything, things hadn’t become awkward or stilted between me and my mum since we fucked. There had a been an uneasy week or two, where I think we were both worried about if the other regretted our initial tryst, but it soon went away. In the two months since, we had fucked several more times, usually when our lust just got the better of us.

Christmas rolled around, and things were better than ever. With my dad working longer hours, me and my mum were fucking nearly every weekday. We put up our decorations and had sex on the floor in front of the tree, my cum once again splattering her beautiful face. On the 23rd, my sister returned home from boarding school. When I was around 13, my parents came into a good amount of money, and offered me a private education, I turned it down, having built a good group of friends at my public school. My sister on the other hand, when she turned 11, jumped on the chance. Seven years had passed, and she’d just turned 18, and was partway through her final year at the school. We had a relatively normal Christmas day, other than my mum stroking my leg under the dinner table, which was a thrill as my dad sat right next to me.

Unlike my Dad, Claire, my sister, is very perceptive. She noticed me and my exchanging knowing glances at each other across the table, and when I jumped as her leg snaked up my thigh. Claire looked at me, and then at my mum, several times during lunch, looking ever more suspicous. I tried to shake it off, she was perceptive yes, but there was no way she could be that perceptive.

The 28th rolled around and my dad went back to work, with Claire in the house me and my mum were unable to fuck, which I know was making us both very pent up. I went into the kitchen at lunchtime and wrapped my arms around her, kissing her on the ear, she gave me a playful squeeze through my trousers. She went to go through the back door, to water her plants, and I gave her a playful slap on the bum to which she giggled. I turned to leave the kitchen and came almost face-to-face with Claire.
“Oh,” I gasped, my heart jumping, “I didn’t see you there.”
Claire just raised an eyebrow. She was a very attractive girl, taking after her mother. She had long brunette hair, a chiseled, almost boyish face and a body to die for. She was slim, with wide hips and large breasts, again, like her mum.
“Um,” I said nervously, “how long were you standing there?”
Claire smiled, “Oh…from around the time mum grabbed your crotch.”
I grimaced, trying to think of a way I could play it off.
“I’m sure that was an accident,” I said, pushing my way past her and down the hallway to my room.
“Yeah right!” Claire laughed, following me, “I’m not stupid, I know something is going on. I saw the way you two were looking at each other on Christmas day, what’s going on?”
I sighed and rolled my eyes, turned out she was that perceptive.
“Nothing, I don’t know what you’re talking about.”
“Seriously…” Claire whispered, following me into my room and shutting the door, “are you and mum…you know?”
“I know?
