"Crawl onto the bed," Shawn instructed Luna. The two of them had stripped, and Shawn was sitting on the bed, his legs out in front of him, his cock hard. Luna stood at the foot of the bed, and as she bent over to climb onto the bed, her C cup breasts swung under her, giving Shawn a marvelous view. She crawled in between his legs and waited for more instruction.
"Good, now start with a hand job," Shawn commanded. She did as she was told, wrapping her hand around his thick dick. It was so large that her fingertips didn't even touch. Luna slowly began to move her hand slowly down the shaft and then back up.
"Very good. Now I want you to move to a blowjob. Did you do any of that with Evan?" Shawn asked her, wondering just how much his best friend had done with his sister.
"Yes," she told him honestly. She could barely believe what was happening. How long had she dreamed of this? She lowered her head until her mouth was at just the right level, and then she opened it, snaking her tongue out and around this tip of his mushroom-like head. She tasted his precum and moaned in delight. Then she began to lick slowly down the underside of his shaft, until she reached his balls. She fondled them with her hands and sucked on them before licking her way back upward.
"God Luna, you're a natural," Shawn encouraged her. She licked around his head again before engulfing it in her mouth, a few inches at a time. She'd take an inch more in and then pull back, and then do the same thing over again. Her hand moved down to her clit, playing with it, moistening her sex.
When he hit the back of her throat, she gagged and pulled off, or rather, she tried to pull off, but Shawn wouldn't let her. "Uh-uh," he said, shaking his head "I want you to swallow my cock. Let it slide down your throat." But Luna didn't want to, and she tried even harder to pull off. After a few minutes of struggling, Shawn let go of her head and she took her mouth off of him.
