Amy usually wore a short cotton nightshirt, but tonight she wore just the tops of her black satin pajamas. They were almost as long as the nightshirt anyway, and offset her brown hair in what she thought was a very attractive manner. They also showed off her long, slender legs.
A thunderstorm was forecast for that night, so her stepfather Conner made sure all the windows were closed before they all went to bed, not wanting to get up in the middle of the night to do it when it started raining.
A little past midnight, the storm hit, with lightning and loud thunder. Jeff was watching the lightning from the comfort of his bed, when he heard a knock at his bedroom door.
"Jeff, are you awake?" Amy asked.
"Yeah, just watching the lightning," he replied.
"I wanted to finish what we started earlier today," Amy said in a husky whisper.
"I guess we could. C'mon in," Jeff replied.
As the flash of lightning filled the room, Jeff could see her in the darkness of the room, her body in front of the window. Lightning flashed outside as she slowly pulled her night shirt over her head, her long brown hair falling about her shoulders as she dropped the night shirt to the floor. Jeff stared at her body, as the room was lit up by the lightning flashes. Her breasts were softly hanging free of a bra, and she was wearing no panties either. Amy had shaved her bikini area so there was just a strip of brown hair above her pussy. Amy gently climbed into the bed and knelt by his legs.
"Let's get these off you," she said as she grabbed his boxers briefs and lowered them down his hips.
Jeff's rock hard cock jerked up and almost hit her chin as she lowered his shorts.
"Nice, very nice," Amy whispered.
Amy leaned up an kissed him. Her tongue parted his lips and found his own tongue. Her lips were so soft She slowly licked down his neck to his chest. Her lips found his left nipple while her fingers caressed his right nipple. The feeling was sensational as she licked first one and then the other. Amy kissed her way down Jeff's stomach, and he closed his eyes, anticipating her lips on his hard cock. Jeff opened his eyes when he felt her hot breath on his cock. She looked up into his eyes as she brought her mouth down to his cock. Jeff almost died when his dick slipped past her lips and into her mouth. It was so wet and hot, her mouth moving up and down, saliva trickling down onto his balls.
"Tell me when you're going to cum," she said when she came up for breath.
Amy resumed her attack on her stepbrother's cock, her lips wrapped around the head and her tongue licking the sensitive underside, her hand pumping his shaft at the same time.
The feeling was getting to be too much for him; Jeff could feel the urge to cum getting stronger.
"I'm going to cum soon," he groaned.
Amy doubled her efforts, pumping his shaft, attacking the head of his cock with her lips and tongue. She looked up into his eyes with lust filled eyes, and that did it. Jeff exploded in her mouth, his hips pumping his dick up into her mouth. Amy swallowed every burst, a little leaking past her lips and dribbling down her chin.
Amy let his softening dick leave her mouth, licking her lips to get the remaining drops.
"That's lesson number one," she said, "Always let a girl know when you're about to cum when she has your dick in her mouth. Not all girls like the taste like I do."
Jeff looked down at his deflated cock and then back at his sister Amy.
"Oh, the night's not over yet," Amy said with a husky voice. "I think you'll be up for another lesson soon. I have a few things to teach you!"
The lightning flashed and the thunder boomed.
Jeff was sitting up naked in his bed, still a little shocked by what had just happened. His stepsister, Amy, was sitting there, also naked. She had just given him a blow-job and had told him that he and she were not done just yet. Amy noticed the look on his face and moved closer to him and wrapped her arms around him.
"Don't worry about anything that happens tonight," she said. "You're my stepbrother, and I would never do anything that I thought would harm you or me in any way. Let's just have some fun with each other, I'll teach you everything you'll need to know."
Jeff thought about that and realized that she was right.
Jeff nodded his agreement and Amy smiled.
"Now just lie back, and let's get comfortable," Amy replied.
They both lay back on the bed, on their sides facing each other. The rain was still beating on the window outside, and when the flash of lightning would light up the room, he could see her face, her eyes looking deep into his own. They both leaned into each other at the same time, his lips meeting hers as they shared a soft, almost innocent kiss. He was enjoying the delightful wickedness of this all. Amy opened her mouth and her tongue flicked against his lips, seeking to pry them open. He obliged, and her tongue slipped onto his mouth, seeking his tongue. As their tongues twirled together, his hands started to explore her body. Jeff reached down to feel her tits, marveling at how soft and silky they were. Amy's nipples hardened as he caressed them, rolling them in between his fingers. Jeff rolled onto his back, pulling Amy on top of him. He could feel her nipples against his Chest. Amy's hair cascaded down onto his face as they continued their kiss. His hands slowly moved down her back, towards her firm ass, that he had so long admired. He felt her cheeks in his hands, loving the way they felt as he squeezed them. Amy moaned and rolled onto her back, bringing him around on top her as she broke their kiss
"Time to learn how to please a woman," she said.
Amy took his head in her hands and guided his lips to her breasts. Jeff kissed first the left, and then the right nipple, both nipples hard as rocks. He slowly licked her left nipple with his tongue, and then taking the whole thing into his mouth, trying to devour her whole breast. Amy guided his mouth over breasts, first one, and then the other. Jeff felt he could spend all night just suckling on her nipples, but Amy had other ideas. She moved his mouth down her soft belly until he could feel her pubic hair against his chin. Jeff looked down and saw what must have been heaven! He could smell her muskiness and see a faint glow on her lips where she was already getting wet.
"Start by licking up and down my lips, you'll learn fast enough what gets me going," Amy replied.
Jeff hesitantly licked at her lips, finding the taste not as sweet as the porn magazines were always saying, but still not a bad taste at all. He started at the top of her lips, and let his tongue slide down between them until he found her hole at the bottom. Jeff dug his tongue into her pussy and he heard Amy let out a light moan. As he tasted her on his lips, He felt Amy guide his head up to the top of her pussy, and felt a small nubbin against his lips.
