Background:
Mark and Melanie are twin brother and sister. Since the Ferris Wheel/lightning incident a few weeks earlier, they had discovered that they could feel what the other twin was thinking about themselves, and what other people were feeling toward their twin. At least, they could feel sexual thoughts, and they found that they were suddenly very hot for each other. Both seemed to be somewhat normal when they were apart, however, when they were together sex was foremost in their minds. Sheri is Mel's best friend. Jim is Mark's best friend. (See "Summer Of Discovery 1-7" for more details of these events.) Enjoy!
The twins had invited their best friends up to their parent's cabin for a three-day weekend. Mark had been dating Melanie's best friend Sheri, and Melanie had began dating Mark's best friend Jim. By 'dating', I mean they had discovered, with their sibling's help, that the friends had the hots for their sibling. So, even though the twins had come to enjoy sex with each other every day lately, they each had new partners to discover exciting and different ways of getting close. And the last couple of days had been very exciting and revealing for them all. It is now the last night of the trip.

Mark felt Melanie's tongue licking his cock. Her lips and mouth slowly swallowed his head and he could feel the blood rushing up into it, filling her mouth out. She held it with one hand while she sucked it, making it rise until it was pressing against her throat. He could feel her hard nipple where she pressed her breast against his leg as she sucked and stroked his now-hard cock. He felt her throat relax as she took him fully, letting him slide deeply down her throat. Her beautiful eyes looked up lovingly into his, seeming to ask if he liked what his sister was doing for him. With his mouth wide open in an "O" shape, he could only moan his delight and acceptance. Then he awoke with a start!
'What the hell!' Mark thought to himself, confused. 'What's going on? That couldn't have been a dream.'
He quickly looked over at Sheri, who was sleeping soundly on her side next to him.
'Well, it wasn't her sucking me.' He thought.
He looked down and saw that he did, indeed have a raging hardon now, which was tenting up under the sheet. Then he felt the lips on his cock again and realized what was happening. Mel was doing this to him in his sleep, sending her thoughts of what she wanted to be doing to him right now.
'Wow, she's even getting into my subconscious now,' he thought, and wondered if she was awake or asleep. He had to go to her to find out.
Quietly slipping out of bed, he tiptoed into Mel and Jim's bedroom. Jim was lying on his back getting a fantastic blowjob from Mel. However, she was pretending that it was Mark's cock she was sucking, and he could feel every little thing she was doing to him. Jim spotted him standing there inside the door and was surprised and startled.
"Mark, what are you doing here?" Jim asked.
"Oh, I'm so sorry, Jim. I didn't mean to disturb you guys. I just woke up with this strange feeling and I thought that Mel wanted me, needed me for something."
Realizing Mark was there, Mel paused her sucking and looked over at Mark, who was standing there nude, not able or bothering to hide his big erection.
"Oh, I DO need you Mark." Looking up at Jim, she continued, "Jim, it's our last night here in the cabin together and I would really like it to be a memorable one, one we could all have fond thoughts from, forever. Do you mind if he stays? I'll take good care of you. You know that, don't you?"
"I guess it's OK, as long as you don't stop what we have started here." Jim replied.
"I've been wondering what it would be like to have both of you at the same time. Tonight, I'm going to find out!" Exclaimed Mel with excitement in her quivering voice.
Mel gave Jim a deep kiss, then swallowed his big cock one more time to be sure he was ready for her. Facing his feet, she straddled his waist on her knees, hovering above Jim's massive cock, rubbing it with her hand over her pussy and clit to get herself ready to receive it inside her. She looked lovingly at Mark, standing there watching and waiting, and admired his long cock standing out straight in front of him. Spreading her pussy lips with her fingers, she sat down on Jim's cock until all but the last couple of inches were inside her hot, wet pussy. Jim groaned and moaned at the wonderful feeling of Mel's pussy engulfing him. Until a couple of weeks ago, he had never had any girl take his cock so easily and willingly, the way Mel was taking it now. He could care less what else she wanted to do, as long as she could keep doing this to him the way she was now.
Mark was fascinated, seeing Mel sitting on his friend's big cock and obviously loving it inside her. Of course, he had seen it inside his girlfriend, Sheri, the day before, but was obstructed by Mel licking her at the same time. He was also pretty busy fucking his sister from behind at the same time. Now, he had a clear view in the adequate light from the single lamp in the room. His eyes were wide open and taking in everything in front of him.
"Mark, come here. I'm ready for you now." Groaned Mel in a deep and sultry voice.
Mark walked to the foot of the bed and stood there, barely a foot in front of Mel, and reached out to caress her firm, pointy breasts with each hand. Her nipples were hard already from anticipation. Not wanting to rush, Mel rose up and lowered her butt down on Jim again, causing a moan from deep in her throat at the feelings of Jim's hard cock inside her, and her brother's hands sending electric shocks from her nipples down to her clit.
Reaching out, she grasped Mark's cock, causing it to twitch in her hands. She stroked it several times, bringing her head forward and closer to it as she did. She knew he wanted to feel, for real, what she was doing to him while he was asleep. It was no accident. She had sent him those feelings on purpose, meaning to arouse him and get him to join them, just as he had. She wanted him in her mouth right now, while she rode her lover Jim's hard cock at the same time. It was something she had never done, being with two guys at the same time, and nothing she had even dreamed of until recently. Of course, she had shared her brother with Sheri the day before, but this was different. This was for her, one for two, not two on one. It was so exciting that she shivered and squeezed Jim's cock with her PC muscles, causing a loud moan from him.
