Summer Of Discovery Ch. 09

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 1-8” for more details of the events leading up to the present.) 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. The trip had been very exciting, exceeding all their wildest expectations. Now, they were almost home.

Cousin Tammy:

Mark dropped off Sheri and Jim at their houses and made a beeline for their own home, not far away.

“I can’t wait to get you home and take care of our little ‘problems’,” said Mark to Melanie.

“Yes, I know exactly what you mean. I can see that big bulge in your pants and I wish I could take it right here and now. Sucking Jim in the car was such a turn-on, and hearing Sheri giving you a play-by-play of what we were doing made me even hornier. At least they got off, but we didn’t. Does it hurt being hard for so long? I know it’s been that way for quite a while. I could ‘see it’ in my mind, you know.” Answered Melanie.

“Yes, it hurts a little, but in a good way. You know, Sheri would make most guys completely happy, so why do I want you so badly? Yeah, I wish we could do it right here and now too, but we’ll be home soon, and can be more comfortable there. I hope Mom and Dad are out somewhere, don’t you?”

“Sheri is very sexy. I know what you mean about her. I wish I had breasts like hers. They are so big and full.” Said Melanie, as she slid over close enough to reach Mark’s bulging crotch. She stroked its length, with an occasional squeeze of anticipation.

Mark replied, “Your breasts are beautiful. I love their firm cone shapes, the way they stand out so proud in front of you. The contrast of their while flesh on your tanned body makes them even sexier. And, I swear, they have gotten bigger since the lightning strike, don’t you think? Not that there’s anything wrong with Sheri’s, mind you! You just wait ’til I can get hold of them and I’ll show you how I like them.”

“Yeah, they DO seem bigger. And this seems bigger too.” Mel replied as she squeezed Mark’s bulging cock through his pants. “I don’t know what’s happened to us, but I’m liking it a lot!”

Upon reaching home, they rushed to unload their camping gear and check out the house to see if they could “get together” soon. To their surprise, their mom, Betty, met them at the front door, giving both big hugs.

“Well, I’ve got a surprise for you and I didn’t want you to get shocked and drop your stuff in the house.” Said Betty. “Your cousin Tammy has come to visit for a while. We’ve been waitin’ for you to get home. Go on in and greet her.”

They both rushed in and hugged Tammy. She was one of their favorite cousins. They grew up near each other and had played together often as kids. Tammy had gone off to college in the city and was about to start her junior year there. They hadn’t seen her since last summer. She looked more mature, but still the same old Tammy. She was blonde, like Mel, but her hair was darker and shorter than Mel’s. She was tall for a woman, almost as tall as Mark, and her figure was very pleasing.

“Hi, Tammy, long time, no see. How’s everything at college? You’ll have to tell us EVERYTHING,” Mel greeted her, implying that she wanted all the juicy details too.

“Yeah, it’s good to see you, cus,” said Mark, trying to hide his bulging hardon from her. “We’re starting to college in the fall, so you’ll have to fill us in on what it’s like there.”

“My, my, you two have grown so much. Let me look at you two.” Tammy replied.

“Hey, I heard about the lightning incident at the fair. Are you two alright now?”

“Oh, yeah. We have a couple of little side effects, be we are dealing very well with them, fer sure.” Smiled Mel in reply. ‘If she only knew what those side effects WERE, she’d freak.’ Thought Mel.

“Well, she’ll have to sleep with you, Mel,” said Betty. “It’ll be like old times when you were kids. Remember all the sleepovers you two had? Now, I’m just getting dinner, so you three go put all your stuff away and clean up, ok?”

Mel and Mark were excited to see their cousin. They had always liked her and had fun together, being only a couple of years apart in age. But there was that little ‘problem’ in the back of their minds that they couldn’t take care of right now that caused them a little distress, the ‘problem’ that only nudity, touching, caressing, sucking, and fucking could fix for them.

As they were preparing for bed, Mel reminded Tammy, “Be careful when you go the bathroom. Remember, Mark and I share the bathroom between our bedrooms, and you could be in for a BIG surprise if you rush in unannounced.”

Tammy wondered just how big a surprise it would be. She had felt Mark’s penis pressing against her when they had hugged earlier and wondered what could have possibly made it so firm in the middle of the day like that? She could see him trying to hide it from her and his mom, not wanting to explain those types of things to either one of them. He had certainly matured in the last year. She’d never had those thoughts about him before. Oh, well, time for bed. It had been a long day for all.

Mel lay down on her side of the queen size bed, legs bent up in a spoon position, her hands clasped flat together between them, little fingers pressing at her clit and pussy lips, seeming to be seeking some relief. She thought to Mark, who was just going to bed himself, ‘Oh, Bro, I wish you were here in bed with me now. I want you so bad.’

‘I know, I want you too. We’ll have to wait ’til we can get some time alone.’ Mark thought to her, blowing her a kiss. ‘Goodnight Sis. Sweet dreams.’

‘Goodnight, and same to you.’ Mel replied, as she blew him a kiss back and drifted off to sleep.

After a while, she felt something. Mark was lying next to her and sucking on her titty.

‘Mark, what are you doing? Go back to bed. We’ll get caught!’ She thought silently to him.

‘I can’t wait. I need you so much. Feel me and you’ll see. How can I sleep with this?’

She reached down and grasped his member. ‘Ohhh, it feels so big and hard. You poor dear. We must take care of this so you can sleep. Maybe if you just put it in me real easy and we can lie here and not move. We don’t want to wake up Tammy.’

She kissed him, then turned over, offering her back to him, and lifted a leg to allow him access. He slid in behind her and lifted her nightgown, letting his cock slip between her legs, rubbing her vulva and clit, eliciting involuntary moans from her at the illicit touch. His hands grasped her breasts, tweaking her nipples to attention. He kissed her neck and the side of her face, feeling their bodies melding together as one. His hips moved on their own, moving his cock between her legs and over her pussy, which started juicing in anticipation of feeling it inside her.

“Ohhh, Ummm, Mmmm,” She moaned.

‘Shhh, musn’t wake up Tammy.’ Mark warned, continuing his teasing over Mel’s body.

Mel cradled the bottom of his penis with her hand as it slid across her pussy. She reached inside her lips and scooped out some liquid, rubbing it over his cock to make it slide better. Holding her hand over the bottom of it, she let him fuck her hand/pussy, enjoying the feel of his long hardness exciting her pussy beyond the point of no return. She had to feel him inside. Grasping it firmly, she reared her hips back and pressed the head of his cock into her eager pussy.

‘Ooooooooooo’ She moaned constantly as it slid deeply into her fiery depths.

‘Ahhhhhhhh’ He moaned back, feeling his hard cock being sucked up fully inside his beautiful sister’s hot pussy.

She took it all, as far as it would go, and they laid there in quiet ecstasy, her pussy milking his cock from inside, his cock throbbing back at her. They wanted to move, but knew they shouldn’t. Mustn’t wake their cousin! His hips contracted involuntarily, pressing his meat through her grasping pussy muscles as she pressed her own hips back to meet him in her own reverse pelvic thrust, her top leg wrapped back over his, helping pull him in deeper. They keep this up for what seemed like hours, him thrusting, her pushing back, pulling him back inside her with short, slow strokes, again and again.

She buried her face in her pillow to stifle her moans. Her hand reached back and felt his hips thrusting into her, making her moan more. The fingers of her other hand were playing her clit like a virtuoso on a piano. His hands still grasped her breasts, her nipples aching from the pinching, feeling it all the way down inside her, all the way to where his cock was filling her, filling her need, about ready to fill her with his seed.

Mel came in vibrating convulsions, her face buried in her pillow to stifle the moans. Mark kissed her neck and squeezed her breasts to help her through her climax, then let go and released his own cum up deep into her smooth, hot depths. She felt him cumming and came again herself, milking all his hot come from his throbbing cock.

“Wake up, Mel!” Yelled Tammy to her cousin. “You’ve slept long enough. Let’s go get breakfast.”

Mel felt groggy. Where was she? Oh, yeah, in her bed asleep. ‘Oh, NO, where’s Mark? He was behind me the last I remember.’ And she jumped up on her elbows, lying on her back, forcing her eyes open to see what tragic scene was in front of her.
