The image quality was pretty good, not HD but not bad, though no color. Probably optimized to maximize storage space. And it dawned on me where it was... “Your house, right?” I said, adding, “Nanny-cam?”“Yes. And yes – just. Watch.” said Gloria, waving me to silence.The image was darker, then lighter – same features in frame, then two figures stumbled into the room – there was no sound. A man and a woman. The man, fully dressed complete with tie. They were… at this point, it looked like they were. I grinned at her as I assumed that my randy little sister had gone off to bed for a wank."Anyway," mum laughed, "you still have me. Let's finish our drink and have another dance." Okay." I grinned.Though still frustrated I was feeling a lot happier, the time spent watching my mother and my sister in their whispered conference had allowed me to cool off a little and my cock was only semi-hard. Draining my glass I took my mother's hand and stepped to the centre of the room, with a smile she moved. Painful, but erotic.She grabbed a flogger, and struck my legs. More pain. She then took an ostrich tickler, and began to tickle my stomach. She moved the tickler to my cock and balls. I became erect.“You don’t have permission to get hard”, and struck my cock with the flogger.She grabbed a bucket of ice, took an ice cube, and rubbed it on my cock. More pain. She moved the ice to my nipples, then my stomach, then the soles of my feet. She removed the restraints.“Get up. Bend over”.She. I push her down as I shake my ass so the towel falls. Her mouth opens without encouragement today. Her gag reflex has definitely settled down as I move in and out holding her hair and the back of her neck. As she gets good and wet in there I pull out so that she can catch a few good breaths before I slide in and my balls go off of her chin. This she resists to, but I hold her steady for a few minutes of deep strokes and I let her go. She looks at her fiance' and he just smiles as he leans.
