He shakes his head and walks off to the bathroom.

As you watch your dad walk away, an evil smirk crosses your lips, you'd anticipated his **** and had a word with a friend whose speciality was science. It also didn't hurt that he'd just gotten the Daniels injection and had needed breeding, after a marathon hour long session in the bedroom he had at the back of the lab, he gave you an experimental **** that was part aprhodisiac, part fertility **** and part sedative.

You left him with the promise that you'd go back and fuck him again for some more of the ****. After sharing one final toe-curlingly powerful kiss, you took the **** and headed home where your dad, not unexpectedly, spurned your advances. Once your dad left the room, you noticed that he'd left his drink of scotch unattended, smiling an evil smile, you quickly empty the contents of the vial into your dad's glass before topping it up and mixing in the ****.

You got yourself a coffee while you waited, wanting to remain sober for the evening, you did pop a viagra into your mouth and swallowed it, wanting your cock to be as hard as possible for the evenings 'festivities'. About fifteen minutes later your dad came out of the bathroom, wearing nothing but his towel, his hair still wet from the shower as he sat down in his favourite chair.

You nod over to him and raise your coffee cup and say.

"Bottoms up Dad!"

He smiles as he raises his glass before surprising you by downing it in one go. You slowly sip your coffee as you watch the **** slowly take hold of him, his face started going red, his pupils started dilating and his breathing started getting heavier.

"S-Son, c-can y-you help your old man to his bed p-please?" He slurred.

You feigned ambivalance and stood up, walking over to him you had just gotten your arm around him when his body started going limp. Using your strength, all those years pumping iron helping out, you lift your dad bridal style and carry him to his room. Laying him down on his bed, you flip him over into a doggystyle position, his torso on the bed, his asshole exposed to you. Taking precautions, you put a piece of plastic sheeting under his cock to catch his ejaculate so that there'd be no evidence on his bedsheets in the morning.

Once you were sure that he wasn't going to fall off the bed, you got your lube out along with a buttplug. Lubing up your eight incher, you squirted a bit in and around his winking hole before rubbing your throbbing hard cockhead up and down his hole before easing yourself in with a 'POP'. Your dad grunted in his sleep but you weren't worried, you had faith in your friend.
