First of all, apologies for leaving it such a long time since my last post. Time has just slipped by, but I plan to put this right with this new submission. The good news is that my sister and I are still engaged in our incestuous relationship. We both still enjoy that unique feeling of brotherly cock buried in sisterly pussy (bareback of course). Unless you've experienced this, you really don't know what a great feeling it is to unload oneself into a sibling, so here I am with a new adventure of ours. This one occurred recently and involved an invitation to visit our cousin and his wife. To be upfront and avoid any disappointment, neither of them engaged in our sexual activities but did unknowingly host it. So, without further ado, I'll begin the story...
We were walking back to our cousin's house from a local restaurant with my sister and I were in front our cousin and his wife.
"We can see your stocking tops!" his wife exclaimed.
I felt my face redden with embarrassment and a little anger as I recalled the 'debate' my sister and I had earlier. I'd warned her that she shouldn't be wearing such a short dress with our cousin as it did flash her stocking tops when she walked. Normally, I really enjoyed her showing a glimpse of her stockings in public but for the visit to our cousin I'd said she should be more discreet. Flashing stockings whilst out with a cousin and brother wasn't normal behaviour and we shouldn't give family members any reason to question what she was wearing. She'd refused to listen to me and now here we were with the teasing display being seen.
"Really, sorry?!" my sister responded, before pulling at the hem of her dress to take it a little lower though I doubt it made much difference. As she threaded her arm through mine, she looked across at me, widening her eyes with amusement. Christ, she was dangerous at times. Thankfully, the matter wasn't pursued further, and we continued our walk back to theirs (though I wondered if my cousin's wife wouldn't bring it up between them later).
The rest of the evening consisted of a few more drinks, chat, and plenty of laughs. Finally, it was time to retire to bed. My cousin's house is a townhouse and I'd been assigned their son's room on the first floor whilst my sister had their daughters across the landing (both were staying with friends for the night). Their master suite was above, on the second floor.
We said our goodnights and after brushing my teeth, I made my way into their son's room, stripped down to my briefs and got into the single bed. I thought of my sister across the landing and couldnt help but slip my hand into my underwear and gently stroke my cock as I thought of what I was missing. In the silence of the house, I felt myself slowly nodding off. Before I fell fully asleep though, I saw the bedroom door open and in the dim light of the hallway nightlight, I saw my sister. The short dress had been discarded and she was now resplendent in stockings and suspenders. She looked so damn sexy but before I could say a word, she slipped into my room, closing the door behind her.
"Feeling lonely?" she whispered.
"What are you doing?" I replied.
"What does it look like? Providing you with company. Put the bedside lamp on so I don't trip in the darkness."
I did as she asked and as I blinked my eyes in the sudden light, I couldn't help but stare at her with desire. As always, the sight of her in underwear had an instant effect on me and I felt a tingling in my cock.
"It's too dangerous. Us misbehaving at our older parents is one thing but at our more switched-on cousin's..."
"Misbehaving...." she cut across me "...you mean fucking. And that's exactly what I want to do now."
She walked across the room and tossed the duvet aside before seating herself on the edge of the bed. As I looked at the tan stockings attached to her blue suspender belt, I felt my cock stiffen and she must have noticed it too as her hand moved to my crotch and squeezed it.
"You're getting hard already. Tell me you don't want to feel your cock sink into my wet pussy."
"I'd bloody love to but they're just upstairs."
She placed her hand inside my briefs and I felt the cool skin of her fingers as she wrapped them around my now fully stiff cock. She leant forward and lustily kissed me. Of course, I responded and looked into her eyes, knowing my resistance was crumbling. I wanted her, despite the obvious risks, and she knew it.
"We'll be really quiet" she whispered into my ear. "You won't even have to do anything. I'm going to ride you until you pump that baby batter inside me." We never used protection and though we'd not had any 'accidents', we both found the fantasy of an incestuous pregnancy a huge turn on.
