After twenty minutes or so, yes!

As you sit and eat dinner with your dad, you notice a change come over him, he starts shaking softly, his eyes closed and when they re-open, they glisten pink for a second before focusing again. When they do, they focus solely on you, nothing else.

"Everything O.K. there Dad?" You ask, smiling inwardly as you do so.

He nods before dropping onto his hands and knees, crawling towards you as he does so.

"S-Son, I-I made a mistake a few days ago..... I-I'm sorry....." He says, bowing his head.

"What mistake would that be Dad?"

"T-Turning down your generous offer to breed me. Would you do this weak old man the honor of being the one to breed me?"

"Prove yourself to me..... Start by sucking my cock!"

Your dad gulps and nervously pulls down your shorts and your boxers at the same time, revealing your semi-flaccid cock, already standing at six inches long. Your dad gulps before starting to take your thick cockhead into his mouth, you groan as you feel your dad's mouth for the first time on your cock, it doesn't take long before you're at full-mast, making your dad gag a little bit.

Once you feel that you're hard enough, you pull your dad off of your cock.

"Turn around and bend over Dad..... It's breeding time!"

Your dad nods and quickly assumes the position after dropping his trousers and boxers. The last night that you used the first **** on your dad, you broke your usual pattern by not putting a buttplug in after your dad had discovered it when he went to use the toilet the next morning, you covered it up by reminding your dad that he'd been told by the doctor who gave him the injection to start using buttplugs to stretch his hole ready for breeding.

Standing up behind your dad, you quickly got your virility vial and downed it, dropping the bottle carefully on your clothes. You get right up behind your dad and start rubbing your cockhead up and down his crack, occasionally catching in his hole before holding your cock steady as you penetrate your dad's hole, making him grunt as he feels your cockhead enter his hole with a 'POP' but very little pain.
