Go with the daddy delivery man to his private room.
From Create Your Own Story
The gray haired man grins when you step out after him, and locks the van. You enter the Spa a bundle of nerves. The entrance is smallish, with a tall slender man behind a counter who greets the gray haired man with a nod, and then asks to see your ID.
He smiles and says, "Happy birthday," to you.
The gray haired man wraps an arm around you, and says, "Birthday treat. His entrance is on me. We want a room."
The guy behind the counter nods, and the gray haired man pays. He hands the gray haired man a key on a keyring, and then the two of you pass by the counter and go through a pair of double doors.
It looks like a smallish locker-room, you think, and spy a table with a lot of white towels on it, rolled up and ready for us. The gray haired man grabs one, and gestures for you to take another. You take it. Then he steps up to one of the few dozen lockers, opening a couple until he finds one empty. You glance around the room, nervous, and spot a young blond man at the far end of the lockers. He's stripping, and you watch him take his jeans off - he's not wearing underwear, and has already shucked his shirt - and put them in one of the lockers. He smiles at you, turning to face you long enough to show off a decent length of cock and a completely shaved body, and then looks past you and fires off a much warmer smile and wink at the gray-haired man.
You look at your companion, and see him wink back, then start to strip. The blond wraps a towel around his waist, and leaves through the far doors. You shiver, and start stripping, watching as the delivery man pulls off his brown polyester shirt - he's built. He's definitely kept himself in shape, with a smooth muscular chest and thick arms, and a solid stomach. He watches you strip, smiling, and waits until you're naked and tucking your towel around your waist to take his pants off and reveal his long, cut cock. He wraps a towel around himself, closing the locker on his clothes, and smiles at you, picking up the keyring again.
"This way," he says.
You pass through the far door into a hallway, which has numbered doors down one side, and two labeled doors on the other. The signs read: Steam Room, then Hot Tub, and then you see an open doorway with wet tiled floors you assume leads to the showers, given the noise of spraying water you hear. The gray-haired man checks the keyring, and says "lucky number seven."
You pass doors one, two, and three, and then notice that door number four is open. You catch a brief glimpse of a man lying on a cot as you step by, and your eyes widen. He was built like a wrestler, with a huge chest, massive shoulders, and arms bigger than most men's thighs. He stared out into the hallway, meeting your gaze for a brief moment, and holding a massive dick in one hand, which he was leisurely stroking.
"That's Bull," the gray haired man says, and you blush that he caught you looking. "Strong like a bull. Smart like one, too." He grins.
You follow the gray haired man to room seven, which he unlocks. You step inside, and he presses against you, kissing you, his muscular chest against your own already a little damp with sweat in the heat of the building. His tongue invades your mouth, his trim goatee rough against your chin, and then he pulls back. You look around. The room is pretty plain, small, with a wide cot-like bed, and a small table beside it. It's lit with fluorescent bulbs.
"Okay, one last question, then I show you how I get dirty," he says, with a wicked grin. "You want the door closed, or left open?" He reaches down and grabs your cock through the towel.
You...
