Her finger wiggled deep in my ass. I squirmed like a child would and whimpered a little. This was as much from the deed as it was from knowing my Aunt and sister were looking on with undisguised glee.

Here I was, a 39-year-old man lying naked across his mother’s knee, having a deep rectal exam and with an appreciative audience of two other and related women, no less. I had never felt more humiliated, but my cock was already very stiff, though, pressed against her stocking-clad thighs, which had been exposed when she’d hitched up her skirt before taking me over her knees.

‘Hmmm, nothing much in here to speak of,’ Mother finally pronounced. She rapidly withdrew her finger from my anus, and I winced. She looked up at Susan, ‘He needs filling up. Did you bring the balls?’

My Mother had arrived at 4 p.m. that Saturday afternoon and was staying the night. It was positively surreal. We all knew we would not only be forming an erotic and incestuous coupling but also a very perverted one later that evening, yet Aunt Meg, my sister Susan, Mother, and I all sat drinking tea in the living room, talking about anything but what was about to come.

Obviously, the three women had shared and practiced their perverted desires before I came onto the scene, or at the very least, had discussed them at length. There were some knowing smiles exchanged as we all chatted about nothing, and I certainly felt the novice.

I remembered the time when I had last been over my Mother’s knee. As was my usual practice when living at home as a teenager, I’d rush home from school and, taking advantage of the fact that nobody else was around, would go up to the dirty linen basket and wank while sniffing my mother’s or sister’s nylon panties. Then the day came when I got caught red-handed by the hired help, a pretty young Mexican girl.

‘Alex! What are you doing, you naughty boy?!’ she had screamed out loud, having walked quietly into my mother’s bedroom and finding me mid-jerk with a heavily soiled crotch from a pair of black lacy panties against my nose. Of course, I had tried to make my excuses and fumbled with my trousers to hide my cock from view, but it was all too late, and she knew exactly what I was up to.

She slapped me across the face. ‘You naughty little boy! How dare you touch your mother’s things like that? You filthy little pig!’ she screamed before slapping my face yet again.

‘Please, Maria, please don’t tell Mommy! She’ll kill me... ‘ I practically sobbed.

‘Why you no have sex with girl? In my country, boys your age fuck girls, not their mommy’s panties!’

I began to cry. My sexual experiences with girls had been limited to my sister’s incestuous advances. I confessed to being too shy to date girls, let alone try and fuck them.

Her demeanor softened a little. ‘So you no fuck a girl?’

‘Noooo,’ I sobbed, still on my knees, my little cock half protruding from my trousers.

‘Oh, you poor baby,’ she said, coming to me. She then held me, still sobbing, to the front of her pretty cotton skirt. She held me tight, very tight. My nose was pressed hard against her crotch, and after a moment, I felt her rubbing her pussy against my face with slow, rhythmic motions. I felt my cock harden once more, and then she let go of my head and began to slowly raise her skirt. ‘You want to lick my pussy, little virgin boy?’

I didn’t need to be asked twice. Maria quickly hitched up her skirt and pulled off her skimpy panties before lying back on my mother’s bed. I went over to her and, kneeling, buried my face in her crotch that by now was soaking. At last, I was savoring a woman’s femininity in total. I couldn’t believe my luck, and the real thing sure beat sniffing panties. Maria writhed and groaned as I inexpertly put my tongue to work. It was heaven. I couldn’t get enough of her smell and taste, but it wasn’t to last.

‘What the HELL do you think you two are up to?’

My mother had caught us in the act. Maria looked terrified. I tried to explain a way out of the situation, spluttering excuses and crying for a second time that day. My mother just looked at me with disdain. It was Maria who fully confessed to what had happened.

‘So you were found by this poor girl sniffing my panties were you?! You little pervert!’ she screamed in my face. ‘Maria, I don’t hold you in any way responsible. But you, my boy, will pay for this.’

I began to cry.

‘Oh, stop sniveling. So you think you’re a man now? Man enough to suck a woman’s pussy? Well, now it’s time to take your punishment like a man. Maria, you stay where you are. Take your trousers and shorts off, Alex.’

I reluctantly did as she asked. She rummaged in the dirty wash and produced the offending black lace panties and stuck them under my nose.

‘Are these the ones?’

‘Yes, Mommy,’ I sobbed.

‘See those marks? Those stains?’ she asked crisply.

‘Yes, Mommy.’

‘That’s cum, boy. A man’s cum. My lover’s sperm. Sperm that’s dibbled out of my pussy after he fucked me. Now I want you to put them in your mouth and suck his cum while you take your punishment.’

I had wondered why the panties had been so badly soiled, now I knew. Peter, her beau of the moment, was a big and muscular man, several years younger than my mother. He also had a big and powerful cock. I’d seen it when he’d come into the bathroom while I was having a bath and urinated in the toilet with me watching. Although it wasn’t as exciting as watching a woman pee, I had felt my cock stir and had tried to cover the modest erection from him. Sensing my embarrassment, he had shown me the full length of his cock.
