After playing with my tits for a minute,...he put his hands on my shoulders and gently pushed down. I knew what he wanted and I dropped to my knees. I took his slime covered manhood in my hand and stroked it. Open your mouth. Dad put his hand behind my head and pulled it to his crotch. I opened wide and sucked his cockhead into my mouth.

I promised him and I will do everything I can to honor his last will."George was a good man, Liam, never forget that" said a voice.
