She's ready

As your cock slid along her, "Lily, do you want to feel a cock in your pussy?"

"Won't it hurt? Don't go too fast."

"Here, you can be in charge..." You grabbed her torso and rolled onto your back, bringing her on top of you. She again squealed with surprise.

She raised her pussy above your cock, "like this?"

"Yes," you suddenly remembered you had a superpower, "I think this won't hurt much." It hurt you a little, but was totally worth it.

"Okay," she slowly moved herself against the tip of your cock, and lowered herself just a little to push you into her. "Oh, it didn't really... oh my god, it feels so big inside me!"

"It's okay Lily, take your time."

She carefully lowered herself a little more and moved slightly up and down, getting used to the feeling of your cock. Her pussy was tight around you, but you as she slid it in and out, it slowly disappeared inside her.

"Your pussy feels so good, Lily," you reassured.

She started a slow rhythm up and down, "Emma's right, this feels really good."

You were loving he sight of this beautiful girl tentatively riding the length of your cock, and let her take some time to get used to it. She was obviously enjoying the sensations. Her pace got slowly faster, and her breathing was getting heavy.
