Background:
Mark and Melanie are twin brother and sister. Since the Ferris Wheel/lightning incident several 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. At least it WAS that way.
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. Now, their cousin, Tammy was visiting from college.
(See "Summer Of Discovery 1-10" for more details of the events leading up to the present.) Enjoy!
Melanie awoke early, feeling horny as usual. Glancing beside her, she saw that her cousin was still fast asleep. Lying there in the still of the pre-dawn morning, she sensed a dream, not hers but her brother's. He was dreaming about having his penis between his girlfriend's big breasts, fucking them as she licked his head on every stroke. No wonder Mel was feeling so randy. Mel crept quietly to the bathroom between their rooms, peed, and decided she MUST go see Mark.
She went to the foot of his bed, folded back his covers, and crawled up between his legs, eyeing his hard cock standing up proud as he lie on his back. She licked it and took it in into her mouth, savoring the feel, smell, and taste of her brother's fine member. She used her tongue and mouth in rhythm with his dream. He thought his girlfriend was sucking him more. After taking more and more of him, almost deep-throating him, he awoke with a start, wondering what was happening. She looked up and gave him an assuring look, never stopping her sucking. He understood immediately and smiled back at her.
Soon, she climbed up his body, his cock trailing its wetness down her chin, over her chest and breasts, past her bellybutton, over her clit, and slid into her wet pussy. She kissed him and moved her butt back and forth, up and down like it was hinged, fucking his long, hard cock with urgency and need. He kissed her with passion while feeling her breasts and nipples, which were hard from her excitement. Faster and faster they fucked like an old churn.
"Cum in me, please? Make me cum too. I love you so much, baby. I sensed you dreaming about Sheri and just had to have you. But we must hurry before Cus wakes up," Mel groaned.
She fucked him as fast as she could, with him helping by pulling her hard ass cheeks down onto him. In several minutes of this action, they felt their approaching orgasms, then came together in an explosion of cum and clenched muscles. They kissed and hugged each other, feeling utterly spent, not wanting to move.
"Mel, you have to go now. I sense Tammy waking up," Mark whispered.
Slipping her cotton nightie back on, she scurried over to the bathroom door and entered as Tammy was coming in the other side.
"Oh, good morning. I was just waking Mark up. I'm hungry. Want some breakfast?" Mel asked, heading out into her room.
"Good morning, Mel. Sure. I'll be down shortly," Tammy replied.
Mark came in to pee, nude with a half-hardon. Tammy was still there.
"Oh, I didn't hear you. I really have to go pee. Sorry, but I really gotta go. Wanna help me? Want to hold it for me?" Mark asked with a devilish grin.
She stared as he stood by the toilet with his hands on his hips. She reached around him and grasped his deflating, yet still firm penis in her hand.
"How do you guys do this?" She asked, waving it around.
"Aim it down, like a garden hose. Don't wave it around like that or we'll have pee everywhere."
And he started to pee just as she got it aimed at the toilet.
"Ahhhh. I needed that so much. Good job, Cuz. Now wait for it to end and shake it off."
"Jeez, you guys have to work more than we do for this. All we do is sit down and let go." She said, stroking it back and forth and up and down.
"Why is this thing so sticky? Yuk, it feels wet too." "Didn't you wash it after sex with your girlfriend last night? Oh, She's not here is she?" She asked with concern, looking past him into his room to check.
"No, she's not, and you'd better not tell her about us, you know, doing it that one time. I really like Sheri and don't want to mess up things with her."
Without answering her question about being with his girlfriend, he washed off his penis, with her eyes watching his every move.
She grasped it again and said with a smile, "That's better. If I'm going to have this thing inside me again, I want it to be clean."
"Ohh? What do you mean, 'If I'm going to have it inside me again'?"
Smiling, she replied, "Well, after all the stuff going on at the Drive-in the other night, with me being left out and all, and this wonderful dream I had last night, a girl has needs too you know!"
She put a hand on his shoulder and stood up on her toes to kiss him on his lips, feeling his cock firming in her hand. She didn't know what was happening, but whenever she was near Mark, or even Mel, she felt warm and tingly inside. It was a new experience that she couldn't fight. Heck, she didn't even want to fight it. She only wanted sexual satisfaction, and she wanted it now.
"Would you make love to me, please, Mark?"
