Sure, he can use Peter for a while

"Of course, man!" You smile widely at Kyle. "Come on in."

You head back into the kitchen, followed by your fully-clothed neighbor, your bottomless brother, and your naked and cum-stained mother.

As you step inside, you see Peter on the kitchen table, just where you left him. He's lying on his back, still panting in a post-orgasm haze. As you watch his breasts rise and fall with each breath, it's obvious that the huge dose of ****-cocktail-smoothie is already be taking effect. They've swelled visibly while you've been outside; they were already fairly huge globes, but now they may have finally reached the size of basketballs. His ass may be a bit plumper too, but most of that jiggling flesh his hidden beneath him.

As you stand there staring, Mike peers around your shoulder. It doesn't take him long to figure out what's happening, and he lets out a burst of laughter. "Dude! AGAIN? How much did you give him?"

"The whole thing... Well, whatever was left after their morning dose."

April walks in beside you, crossing her arms over her bare (and now relatively small) breasts. "John, I haven't even HAD my morning dose yet! Now there's none left!"

"Hey, no worries. We're gonna have to make a whole new bottle for you anyway... Can't have your husband looking like more of a fucktoy than you do, right?"

She nods firmly. "I'll run get the mix, then." With that she disappears down the hall, headed for the basement where the box of hormone supplements and body modification **** is kept.

Once her round ass has bounced out of view, Kyle clears his throat and you turn to look at him. "So, uh, do you mind if I get started with Peter?"

Hearing his name, your father raises his head from the table and cracks his eyes open. "Oh... Hey, Kyle," he murmurs.

"Why don't you take him upstairs for a shower? He's looking kinda sticky." It's true: Mike's first load from this morning is drying on Peter's lips and cheek, while yours is spilling out from between his legs... And the latter puddle is splattered all over his thighs from the fun he got up to while you were in the yard.

"Sounds good," Kyle replies, practically licking his lips as he advances on Peter's disheveled form. He places a hand on one of his newly-expanded tits, squeezing it firmly. "C'mon, buddy. Let's get you cleaned up."

As Kyle leads your father towards the stairs, you have your doubts about how "clean" he's going to be.
