Yes!

"You're gonna fill your old dad up, but you gotta be quiet, we don't want your mom to hear, do we?" You shake your head no, your cock throbbing and leaking pre from his torturous edging. You stand still and as quiet as you can, little whimpers espcaping you as your dad nibbles your neck. He continues to slowly stroke you, but his hand disappears from your mouth. After a moment, he lets out a small groan of his own into your ear, making your hard cock throb. You can't tell what he's doing, but as long as his strong, calloused daddy hands keep stroking you, you don't really care. He edges you slowly until he finally removes his hand, causing a whiny, needy moan to spring from you.

"Shhh! Don't worry, boy, that monster's not gonna be lonely for long." You turn to see what he's doing and you find him bent over, spreading his cheeks open and presenting his now-lubed and stretched hole for you. You can hardly breathe, hardly think- you'd never considered this before but now the only thing you want in the whole world is your cock in your dad's hole. "Don't make your daddy wait, boy." You don't need further prompting and line your cockhead up with his pucker. You both groan as you push in, and you see starburst in your eyes as your thick meat enters the silky, slick insides of your own father's ass.

You try to go slow, letting your dad adjust to your cock, but he slams back on his own, trapping you against the shower wall as he starts wanking himself off while he grinds against you. "Fuuuck yeah, that's the stuff right there. Breed your daddy, son, fill me up."

That's all it takes for you to lose control, and you grab your dad by his beefy ass and start ramming him with everything you have. You slam into him again and again, losing yourself inside of the tight wetness. You can feel his ass pulse and squeeze around you as you hit his prostrate and he comes, muffling his cries with his hand. You show no mercy, plowing into him even as his legs shake. "I'm gonna breed you, daddy," you say, roughly, grabbing his ass hard enough to bruise. You slam into him a final time, grinding yourself against him as you try to get your spunk as far inside him as possible. Your orgasm seems to last forever, probably a result of the edging from earlier. Finally, you finish, and pull out of your dad. Thanks to your previous command, you're not flagging at all, and could probably go another round. But your dad's leaning against the wall and shaking, your thick cum running out of his abused ass and down his legs.
