As it sometimes happens after a death, my sister and I closed her big house and Barbara moved in with me. I am positive that I didn't have any thoughts of intimacy with my middle aged sister and if Barbara's had any thoughts Barbara didn't give me any hint. Perhaps we should have considered the possibility, because the both of us had, had many years of good active sex with our now cold partners, but there was no indication that the old flames still flickered.
Nothing happened for more than six months. We kept to our rooms, did our own things, enjoyed the companionship at meals and other activities, but our touches were not meant to be stimulating. Probably not that we didn't think about it! Barbara often caught me studying her ample boobs and I guess she didn't miss a chance to estimate the size of my cock.
We have always blamed - or - credited the cold winter for bringing us together. In mid winter a widespread blackout sent us to bed with extra blankets. For Barbara it wasn't enough she couldn't stop shivering. After about an hour of misery, she came running into my bedroom.
"I'm freezing. Can I climb in with you?" she asked
It must have been a relief because she had the warmth of my body plus the extra cover she had carried. First, we cuddled face to face until her shivering slowed. Then, conscious that her big tits were jammed into my chest, she turned her cold back to me. I snuggled to her, making her grateful for my body heat but, a second later, she felt my hard cock poking into her butt. I guess she had no choice of being turned on by my warm body or going back to her frozen bed!. She turned toward me and reached down between us.
"If we're going to keep warm this way," she said. "You'll have to keep this....."
But what she brushed away wasn't hard at all. It was my cock, but it was soft and limp. Maybe because we were in bed and holding each other, was making her think sex, she had probably imagined a big cock trying to get between the cheeks of her ass.
"What are you doing, Barbara? You want to play with my cock?" I asked. She knew I was kidding and she had to keep up with me.
