Jonty bit his lip and considered leaving. But he did not move, not even an inch. He did not move as the teen leaned forwards and placed a light kiss on the head of his swollen manhood, as thought she was testing him. Likewise he did not move as she put up a single forefinger and brushed it lightly over the tightness of his uncircumcised foreskin. Only when that finger reached back to his balls and circled beneath them did he shiver. "Oh yeaaaah! Honey... that feels so good... but we shouldn't, you're my daughter, it's...!"
Her hand flattened, and she palmed the fullness of his balls. "...incest, dad, is what it is." She used just the palm of her hand on his tight sack, admiring the weight of them. "Incest. It's wrong..It's everything that society teaches us is totally evil. But it happens in nature. If two people are attracted to one another shouldn't they be able to show it...?"
Opening her lips, she moved her head forwards. Jonty's view disappeared beneath the nest of her dark hair, but his cock continued to feel as her tongue brushed the underside. "Shouldn't I be able to lick and suck your cock, because that won't get me pregnant?" She followed this up with a big wet kiss right over the head of his fuckrod. "Shouldn't I be able to admire with sheer amazement the instrument that gave me my life?" She used her teeth to nibble at his pink cock head. "Shouldn't I be able to feast on you until you give me a little bit more of your genes?"
It was over then, his resistance. Her wanting baby bird mouth went over his dick with a single fluid action. She wanted it, and he'd never been able to deny his daughter anything she desired. Even his cock. Wrapping one hand around the base she went to work on the first four inches, sucking away and driving him wild with desire. She used everything, her tongue and lips and teeth. His daughter worked his rod like the best lover he had ever had -- in fact better. She was wetting him up, trying to draw his sperm from his bloated balls right into her throat, the throat he had helped to create.
She leaned back, his cock popping out from between her lips for a bare second. "C'mon dad. Give it to me. Give me some sperm!" She went back to work on his cock. Reaching down he pushed back her hair so her could see her eyes in the lamplight. She was looking up at him, begging him for it.
Jonty gasped. He did not know how he was holding back. His balls must have been in shock. His mind was racing ahead. He wanted this to be wonderful, to be perfect. He wanted to cum but never to cum. He wanted... "Oh, honey... you're such a great cocksucker! Would you... would you call me 'daddy'!?"
