As Marty laid there in my arms his cock twitched back to life Beth entered the room.
"Did i hear someone cum?" Beth said with a smile.
"Yes he did," i answered as i kissed his head.
"MOMMY." A call came from my bedroom.
"Ok I'm here baby." Beth called back. "I'll leave you guys to it, love you both." She said leaving us.
Marty lifted his head up and i lowered mine to kiss him as we kissed i stroked his face with my thumb, then kissed my way down his muscular body.
The marines will love him he's a fine specimen of a man i kissed his chest and licked his nipples his cock huge and growing harder all the time.
"Dad, can i suck you?" He asked softly.
"Of course you can, how do you want me? On my back? Kneeing or standing?" I asked.
"On your back i think so i can look in your eyes." He said.
So i pushed all the sheets off the bed and laid on my beck, my cock about 7" shaved and pointing straight up to the ceiling, i opened my legs slightly which are muscular, tanned and not to hairy.
Marty kissed up from my ankles to my knees as he stroked my ball sack gently, as any man knows that's a delicate area.
Marty kissed up above my knees and onto my upper thighs i stroked his head soft and was very vocal in my appreciation.
"Marty take your time we have all afternoon, there's no rush." I said to him.
"OH MOMMY, YES." Came from next door.
Marty got to my balls.
"How should i treat them dad?" Marty asked.
"Lick and suck one at a time baby, I'll guide you as you go." I said to him a little breathlessly at what was finely going to happen.
My beautiful sexy boy was going to put my balls in his mouth for the first time, he was nervous i could tell as his hands shook when they held a ball to his mouth.
His breath hot my balls tightened in anticipation i daren't speak at this moment any distraction would panic him so i stroked his hair by running my fingers through it.
Then i felt it the dampness of his mouth the tip of his tongue finally on my gentility this was the most beautiful feeling I'd ever felt down there.
50 times better than his virgin sisters first time on my balls and a 100 times better than his mothers even though she'd had a few cocks before mine she was great at it but not amazing.
It was Marty's first time with a ball and he was blowing my mind, his hand sneaked up onto my shaft and he gently wanked me, I didn't need to tell him anything everything he was doing was right, it felt right.
"How's it feeling dad?" He asked as he came up to kiss me.
"Your doing perfectly, are you sure you've never sucked guys privates before? Because yout a cock sucking natural." I said smiling as i leaned in for more kisses.
"OH BABY YOUR TONGUES FUCKING GOOD" Beth yelled from next door.
"I haven't sucked it yet dad." He said smiling still stroking it.
"Well you better get on with it before dad shoots his spunk all over your hand." I said gently pushing him downwards.
He crawled down my body kissing his way to my cock which at this point was almost bursting out of its foreskin.
he instinctively licked the hole as he wrapped his lips around the shaft, I didn't want to disturb him he had to get accustomed to the size and taste.
"Dad." He moaned softly.
I didn't answer i was lost in the moment, he placed me in his mouth again and went further down the shaft my balls on his chin.
