Get dressed and hide it under a towel
From Create Your Own Story
It turns out to be harder than you thought to keep your cock a secret, as it doesn't hide easily, even with a towel. Still, you manage to slip into the lab with no one taking a second glance at you. Most of the staff here are used to you acting strange every now and then, and this is the first time you've been thankful for that.
Michelle waits for you, punctual as always, and you sit down next to her. You see that she's changed her clothes, and from the smell, she also took a shower. Not only that, but she also put on some lovely smelling perfume, and a good amount of makeup. Something you can never recall her doing before. She wastes no time and starts attaching sensors to your cock, before starting a series of scans.
"I ran some tests on your semen." she says. "And it's very potent. It's much more viscous and thicker than any normal male semen, the sperm count is off the charts. It's guaranteed to impregnate any women who's ovulating."
"Were you at the time that I... you know?" you asks, as you blush.
Michelle shakes her head. "No. But, here's the other part. Your penis secretes a kind of pheromone that not only acts as a powerful aphrodisiac, it also forces the woman to ovulate."
Your heart skips a beat. "So then, you're..."
She quietly nods. "Yes... I'm pregnant, and it's growing fast. By my estimates, the child will be born in about three months."
