I soon found myself joining my wife in kneeling before my son’s growing erection as my wife’s sister continued to stroke it. I was down between his thighs, kissing up the inside of his leg as my wife licked her tongue around the head of his cock, her sister still stroking it. The two sisters looked each other in the eye and laughed even as they continued to pleasure my son’s dick with their hands and mouths.
“I guess you’re just as much in need of a real man’s cock as I am, sister,” my wife said.
“I’ve never seen one like it,” her sister confirmed, “It’s incredible, so long and thick.”
The two sisters kissed each other across the hard cock and then began to transfer their kisses to the thick, hard meat itself, while I knelt under them and began to lick my son’s balls. Adam now pulled my wife up to sit beside him and began to kiss her again as he slipped her dress from her shoulders and unstrapped her bra, letting those incredible breasts spill out.
“Wow, nice tits, auntie Laura!” Chris said on watching his cousin bury his face in Laura’s breasts as she ran her hands over his muscular chest.
My nephews were obviously beginning to warm to the idea of their family’s incestuous fun, although I could no longer see what they were doing with my face buried between my son’s legs. I began to move my attention to his thick, veiny cock. As Helen began to lick the shaft, I flicked my tongue across the quivering head and inside the tip of his foreskin. Helen looked at me and grinned at the sight of the man that had married her sister, dressed in a PVC skirt and boots, face painted like a slutty whore, sucking on his own son’s cock.
“Wow, you really do make quite a hot sissy slut,” she said, moving her free hand to run across my rubber clad body, “And you do seem so keen on a nice hard cock!”
Between us, me and my sister-in-law continued to suck and lick all over my son’s hard cock while his attention was entirely on his mother, playing with her great, round breasts and then running his hand down inside her panties and fingering her wet cunt. She began to gasp and sigh.
“Oh, honey, oh yes, you’re making me so wet, my hunky son, I want to feel you inside me,” she moaned.
Meanwhile, thanks to me and Helen, Adam’s cock was firm and twitching and just waiting to fuck his beautiful mother. I could see that Helen was as much into sucking and submitting to this fine piece of manhood as I was. It seemed like Adam had all the women in the family just desperate for that nice hard cock of his. And even for the men it held quite a fascination. Like me before, my nephews were obviously beginning to get a dirty thrill from watching my wife and my son getting together, a thrill only enhanced by seeing their own mother on her knees before their cousin’s big, fat cock.
“Oh God, mum’s quite a cocksucker!” sighed Matt.
“Well, Sissy Uncle Steve isn’t too bad either,” his brother laughed.
I turned back to look at them for the first time and saw that they had dropped their pants and pulled out a pair of six inch cocks that, while not as enormous as my son’s, were certainly more impressive than my own. While watching their mother and uncle suck on their cousin’s monster dick, they had both begun to masturbate their own cocks. Obviously, seeing the rest of their family engaged in hot, incestuous sex, they had no qualms about revealing the turn on it was for them in watching.
