Oh yeah!

Parking your truck in the garage, you get out and grab a virility vial and another vial of the potent **** that had served you well before. Entering the house, you see your dad hard at work preparing dinner.

"Oh hey, sport! Dinner won't be long, can you pour your old man a drink?"

You smile as you respond positively before pouring your dad a scotch, adding half of the potent ****, mixing it in carefully before quickly downing the virility vial and hiding the empty vial in your bag, the half empty one in your pocket.

During dinner, pasta and meatballs, you notice your dad getting more and more flushed. You smile as the **** starts to take effect on your dad, his breathing starting to get heavy. You smile as he wobbles his way out to the kitchen, the buttplug still in him from the night before. You take advantage of him having his back to you by emptying the rest of the vial into his drink before topping it off.

Your dad sits back down shakily after putting his bowl in the dishwasher, you stand up and take your own bowl out, catching your dad out of the corner of your eye getting a glimpse of your boner while he downed his drink. You smiled after you turned your back, the **** had once again taken effect.

After having a piss, you washed your hands and then very carefully buried the empty vial in the bin and covered it up with some out of date food from the fridge. By the time you get back in the living room, your dad was slurring his words and looking wobbly.

Walking over to your dad, you turn off the TV and once again help him to bed, as soon as you lay him down, he passes out cold. You smile as you nip into your room and grab a bag of goodies you'd prepared earlier, including lube, a fresh buttplug, and wet wipes. Heading back into your dad's room, you quickly get undressed (the bottom half, anyway) as you pull him to the edge of the bed, carefully you lift his legs up so that you can get his boxers off, dropping them next to him on the bed, you then lift his left leg up high enough that you can remove the buttplug, putting it to one side, you get the fresh one out of the bag along with the lube and wet wipes and place, quietly, the old buttplug into the bag.

You smile as you see no cum escaping from your dads now gaping hole as you lube both his asshole as well as your monster cock, putting down the lube, you pick up the fresh buttplug and rest it on your dad's chest before lifting both his legs over your shoulders, grabbing your throbbing cock with your left hand, you guide it into the now familiar warmth of your dads asshole.

You spend an hour burying your bone as hard and as deep as you possibly can before succumbing to your ejaculation, it felt like you were firing off a cannon, a cum cannon indeed, deep into your dad's womb, before you quickly and carefully replace your slowly softening cock with the fresh buttplug. You also replace your dad's boxers after cleaning all his cum off his groin and torso with the wet wipes before tucking him back in. Taking your haul with you, you head back to your room, hiding your bounty and then getting into bed, dreaming of your dad with a bloated, pregnant, belly.
