I found her standing naked at the bathroom sink brushing her hair while she hummed. It was no particular song, just random tones. She continued what she was doing when I walked in. I wrapped my arms around her and pressed my cock against her lower back. I wasn’t hard but the view in the mirror over her shoulder was having an effect. She felt my burgeoning hardness on her erogenous zone at the base of her spine and she grinned and muttered simply, “Ummm.”
I leaned in and kissed her on the neck and she moaned and tipped her head to the side to allow me total access. Her eyes fluttered open for a moment and then closed again. I lightly kissed her there again and she moaned again. I reached between her dangling arms and cradled her big tits and tweaked both nipples and she moaned, “Oh Honey, I like that.” My cock pushed hard against that spot she had called an erogenous zone, as my thighs pushed against her gorgeous ass-cheeks. Her eyes fluttered open and then shut again. She moaned loudly. Then her hands went to her sex. She held her outer labia open with one hand and strummed her middle finger through her pussy and clitoris. I could see the glistening wetness of her sex in the mirror.
My balls were still aching but the pain was less. I had resolved to hold her here like this so she couldn’t get access to my cock. I needed a little more time but I knew time was running out fast. The twins would be home in hours.
I kissed her on the neck and then her ear and her body trembled against the sink. I maintained my position behind her and watched the reflection in the mirror of her fingers flying in her pussy. My hands kept up the nipple tweaking. They were extremely hard and long. I cupped her tits and applied what I thought was sufficient pressure but she whispered, “Harder, Honey. Be rough with them. You know I like it rough.” I hesitated but then gripped her globes harder. I could tell that she liked it.
Mom suddenly leaned to the left and lifted her right leg to place her knee on the countertop. She turned her head to me and said, “Fuck me doggy.” I hesitated again and decided I’d give her what she wanted until I collapsed dead on the floor. I flexed my knees and bent down lower and guided my cock to her sex. She used her fingers to guide me inside like a ramp and I took over from there. We both groaned hard as my glans entered and again as the biggest part of my cock slid inside. I gripped her tits hard to use as leverage and pounded her pussy in our standing doggy position. It was just like Dad had done beside the twin’s bedroom door.
