What an amazing story! Being the the proud poz incubator son of 2 hot, horny smoke PozDaddies is my ultimate fantasy.
There is nothing stronger than the bond between a Daddy and his boy bound by smoke and the family strain. Devoted to servicing Daddy's needs, worshiping his cock and addicted to his poz cum. Sex is smoke. Smoke is sex. They are an essential combination that fuel each other and feed the soul.
A good boy should always beg his Daddy for toxic replenishment to let him know his delicious gifts are going to be gratefully received and savored. A reoccurring detail in your story that I adore. WOOF!
When a boy gets whiff of his Daddy's pipe/cigar smoke his cock and hole should instinctively throb with anticipation and arouse the family strain in his blood knowing Daddy's balls are full and aching for release. He should immediately spring to attention. His sole focus and purpose to pleasure his Daddy and harvest his dirty cum.
I had to read that last chapter in 2 sessions. When Daddy pulled out his pipe out and started hauling it tipped me over the edge and I shot a massive load (with my briar clenched in my jaw billowing thick clouds naturally) Looking forward to the next installment!
