I drop to my knees with them on either side of the picture beneath me. I am naked except for the bright pink stockings on my legs and it's easy to reach down, give my balls a quick squeeze before I start pumping my stiffening cock. The picture is of my 19 year old niece, Emma, the elfin beauty is wearing a very revealing yellow bikini, a picture she proudly posted on Facebook a few weeks ago. It's not hard being aroused looking at her hot, petite body and I can tell my cum tribute will not take long to reach a conclusion.
I grunt and moan and with a breathless gasp I spray a large load of sticky, white cum all over the plastic pocket the A4 sized picture is wrapped inside. I have coated her face in my sperm, obliterating her cute features.
I hear an audible click as a camera on the phone is stopped and Emma's voice speaks from my right.
"Nice load Uncle Danny, been saving that up? Auntie Donna not been releasing you?"
In the past few weeks my relationship with Emma had charged drastically. Since that fateful night she had burst in on me while I was ironing and discovered that I liked to do that particular activity while my wife was out, dressed in women's underwear while watching gay porn on the TV. It was then I discovered my sweet little niece had developed into an Alpha Domme and she had all the evidence and desire to dominate and humiliate me -- and we both loved it.
She stepped around me and I saw she had fitted that large, black strap on dildo to her crotch and a shiver of anticipation went through me. She put away her camera (with yet another incriminating video of me now on it) and slowly circled me, goading and mocking me with that large black phallus before moving behind me and shoving my head forward and down until it was just over the cum splattered picture of her (that she had supplied especially for this).
"Now be a good bitch and clean up your mess Uncle and try not to be put off with what I'm doing" her voice dripped with condescension and disdain.
All told this would have turned me on but having just cum I was on a downer and feeling guilty and weak. Emma knew this, she loved this and knew it would increase my discomfort, both physical and mental. Obediently I dipped my head and stuck my tongue out and began to lap at my own sperm, as I did so I felt her soft fingers pull my ass cheeks apart and seconds later the top of her hard plastic dick pressed upon my anus. With a hard shove she penetrated me and my head came up in objection but she just pushed it back down towards it's task and began to ass fuck me hard. It was a thankless task trying to lick up my cum as my body was pumped back and forth, I had cum all over my face and mouth in no time. She fucked me like that for about five minutes, at least until I ached before roughly pulling out and pulling me up to my knees by my hair she stepped around and rammed her cock into my gasping, cum covered mouth and made me clean it straight from my own ass. As if my humiliation could not be greater at that point the front doorbell sounded.
I froze. I think my heart stopped. My mind raced through the many terrible possibilities as to who it could be out there. Even the mailman or a delivery driver could be curtains for me. But could it be one of Donna's friends or worse her mother or sister (neither needed a reason to dislike me). Emma's voice was sing song and mocking as she instructed me.
"Go and answer it. No, don't bother with any clothes you are fine as you are and leave your cum on your face."
I hesitated. This was too much to risk all I was wearing were my stained, pink stockings. I look up at Emma but her look brooked no argument.
"Go on bitch, answer it!"
She lifted her phone up, as a clear reminder of the mountain of evidence of my perversions she had immediate access to. The threat was clear so I swallowed and mustered what was left of my courage and got to my feet and stumbled over to the corridor and to the front door. As I got there it rang again impatiently and I nearly soiled myself with the fright. I regained just enough composure to hide behind the door as I opened it enough to see out but not enough for whoever was out there to see anything other than my face. Emma stood in the corridor behind me the strap on around her waist clearly jutting out. On my doorstep was a young black man who I had never set eyes on before. He peered up at me and asked.
"Is Emma in?"
Partly in surprise I released my hold on the door and it swung open further, revealing I was topless, he smirked and stepped up, unbidden and pushed past me into my home. He saw Emma and gave a wave before turning as I closed the door and appraised me. Then he turned back to Emma and asked.
"This your bitch?"
"That's him, my Uncle Danny. What do you make of him Nathan?"
He looked me up and down, focussing his gaze on my crotch.
"He's not very big is he?"
Emma laughed and agreed and then made the suggestion that Nathan should show me what a "real man looked like". She looked at me as she said this and clearly enjoyed the embarrassment it caused. We had moved into my living room and I stood and watched as the young man ( I would say about the same age as Emma, 19 or 20) pulled off his shirt and jeans and then his briefs to proudly display a chiselled, muscular hard body. And a very large, stiffening cock. Emma pushed me towards him and was positively giddy as she announced.
"Let's get some cock comparison pics shall we, see just how inadequate you really are Uncle."
We stood facing each other and the difference in size was galling. Even though I was regaining a bit of wood, especially as Emma gave my balls a playful squeeze, I was not at my full length. Nathan meantime was at least ten inches long and his dick was already pressing into my abdomen. My white cock contrasted with his shining ebony colour and only emphasised the massive size difference between our cocks. I was twice this boy's age but his cock was two or maybe even three times the size of my four inch dick. It was hugely humiliating and Nathan knew it as he held my gaze and smirked at me. Neither of my tormentors needed to say anything to make me feel any more inadequate. I also felt more and more aroused but my stiffening cock made little difference to the size difference. Whether my arousal was due to the humiliation I was feeling or the closeness to Nathan's impressive member I did not know. Emma made sure to get a series of pictures of our cocks together before placing her hands on my shoulders and slowly pressing me to my knees before Nathan.
"You need to learn your place old man, Nathan turn around let's start him off worshipping your fine ass."
He turned 180 degrees and I was faced with two, firm, gleaming black buttocks.
"Kiss them," demanded my niece.
