The local gym

You venture towards a gym, rather exclusive in its appearance and with many cars parked outfront. You decide this is perfect.

You walk in and smile at the receptionist behind the counter. The name tag says 'Molly'. "Hello, sir, how are you today?"

"Fine, I am just here for a short while."

" Do you have a membership or any way to pay for a single session?" Molly seems hot under the collar, looking at your peak physical condition as a human.

"Nothing on me," you say as you lean on the counter. "But if you come to the sauna in five minutes, I will have payment for you." You stare into her eyes, coaxing her into a positive response.

"Certainly sir. But I will have to speak with my manager."

"Bring them along. The more, the merrier." You leave her with that proposal and walk into the main part of the gym.

It is rather busy at this time and all you see is hot, sweaty humans, horny and salivating for sex. And, on that thought, you have an idea.

You enter the pool area and notice two men, chatting down one end of the pool. As you approach, your presence causes them to leave. You are now alone in the area. You strip off and slide into the pool. The incubus inside is released and you start to jerk your massive cock while standing in the water. Precum dilutes in the water as you move your hand faster and faster. You don't take long to cum into the water and let the demon sperm infect the water.

As you leave the pool, you shapeshift back and put your clothes back on. Walking towards the door, a swimclass of 10 people enter the pool area. They range in ages from teenagers to pensioners. The instructors jump in one end of the pool and look confused. Your plan looks to be working. Once the humans in the pool get a taste of Lilith, they will want more. They will be open to any sexual activity and their scent will attract incubi and succubi alike.

But you have other work to do.
