As it turned out, Nick's mother and aunt decided to hold their father's 80th birthday bash on the evening of Amber's birthday party at the water park, so Elisabeth and her brother would be going to two big parties on the same day.
Nick hadn't had a good night's sleep for over a week, ever since that strange experience in the cemetery. He'd wake up in the middle of the night in a cold sweat with the feeling of having a familiar nightmare, but he could never quite remember what he dreamt. He knew it had something to do with the spirit that possessed his sister. After all, the spirit had promised him that she would come to him in his dreams and tell him more about his task. But all he could see was Elisabeth's body, writhing against the grass with her eyes lolling back into her head, and a woman with red hair the color of fire whose eyes stared right though him, relentlessly stoking the flame of his lust until he soiled his bed sheets. He was having a hard time washing the stains out before his mother saw them.
The last couple of nights Nick had not tried to sleep at all, and instead sat at his computer all night, reading erotica on the Internet while chugging Red Bull and downing NoDoz.
By the party's eve, he had already read a story about a nun who had sex a centaur, a whole series about a bunch of horny nymphs who staged a kinky battle against an oil company, and countless other stories. Nick had jacked off so many times he was afraid blood would start coming out instead of jizm. He was beginning to read a story about a college girl with an unusual interest in sex toys, which somehow involved Mary Queen of Scots, when he heard his mother, Susan, moan loudly in the other room.
Nick's spent cock sprung back to attention at once, and he leapt from his computer chair, eager to make himself of assistance. For some reason his mother hadn't been sharing his bed for the last week. As much as he felt strange being his mother's sex toy, Nick really missed the wild nights of sex.
Nick was buckling his belt as he pushed open to Susan's bedroom. For a brief moment he was treated to the sight of his mother lying completely naked above the bed sheets, her eyes lolled back in ecstasy, gripping a vibrator in one hand and a copy of 'Better homes and gardens' in the other. Her large well-rounded breasts were distorted oddly by their own weight so that they resembled melted clocks in a Dali panting.
Nick's mouth watered and he began to fumble with the fly of his pants. At the same moment, his mother's eyes met his and she screamed and thrust her vibrator out of sight under her pillow, throwing the blanket over herself.
"What are you doing here!" she shrieked. "You're supposed to be in bed!"
"I couldn't sleep," Nick replied, only a little fazed by his mother's sharp response to his presence. He knew from experience that even women like his mother and sister acted a little weird from time to time. "I heard you in here pleasuring yourself and thought it would only be polite to offer you a hand."
"You'll do no such thing, young man! You'll march back to your room right this instant and go to bed or I'll ground you until you're old enough to drink!"
Nick couldn't help laughing. There were limits to how ridiculous a person could act, and his mother seemed just plain nuts. She needed to get her facts straight.
"Come on, Mom, it's not like it's the first time I've seen you masturbate! Why have you suddenly gotten so prudish? It isn't like you at all!"
"Out!" his mother gasped, sitting up on the bed and pointing to the door. Nick noticed that her blanket was sliding off a bit, giving him a remarkably nice view of her cleavage. He wanted to tear the sheet off and place his lips against his mother's nipple. The muscles in her arm that pointed to the door were so tight and feminine. Nick gulped audibly.
"Stop kidding around, Mom!" he protested, resisting the urge to drool like a rabid dog. His cock was swelling uncontrollably in his pants and he wanted nothing more in the world than to rip it free and thrust it desperately into his mother's sopping wet cunt hole. He bent down and began unzipping his fly. Surely she was playing some sort of game with him to make him extra horny. There was no really no reason why she should be contenting herself with mechanical toys while she had him to play with!
"Out!" his mother repeated. Her eyes flashed so menacingly that Nick found himself back in the hall before he even realized his legs had moved. His hard cock was sticking out of his fly, like a white flag begging for mercy against a ruthless onslaught.
Maybe his mother was having her period, Nick thought, unsuccessfully trying to stuff his still hard member back into his pants. He hadn't noticed a tampon string between her legs when she was masturbating, but then again it had only been a couple of seconds, and he wasn't exactly looking for it.
"And if you're not in bed in 20 minutes, I'm going to skin you alive. You'd better decide that this was some skanky little jerk-off fantasy, and never mention it to me again!" Susan added from behind the closed door.
Nick moved away from the door, feeling completely and utterly confused. He almost had to repress the urge to cry. He was a guy and not used to crying, and it pissed him off that he was so close to tears now.
He sulked back to his room and pulled the blankets on over his head without bothering to undress. He was pretty sure, with all the caffeine in his bloodstream, he wasn't going to be able to sleep, and he was still rock hard and completely pissed at his mother for being such a bitch. What was wrong with her? It was almost as though the two of them had never had sex. Nick knew that wasn't true. He's fucked his mother every which way almost more times than he could count, and he could still remember how she felt in his arms and the feel of her cunt as it milked his cock. Had he done something that caused him to lose his mother's affections? The idea was so horrible that he wanted to rush back into her room, threats be damned, curl up in her lap and beg her to tell him it wasn't true.
Nick didn't notice when he finally dozed off. It seemed like only a moment later that he woke up to the sight of his younger sister Elisabeth jumping up and down on his bed.
"You don't know what happened to Mom, do you? She's acting like a total bitch today. She made me prepare breakfast. Come on, get your trunks on and let's go. Amber's mom will be driving up with her minivan in a few minutes to take us to the water park."
"Where's your swimsuit?" Nick asked, eyeing his sister suspiciously. She pulled the neckline of her pink and white checkered dress to reveal a white bikini top with a large rose on one breast. "Come on, get out of bed!" Elisabeth said, yanking Nick by the arm. "And for heaven's sake, eat some of the food I was kind enough to make you."
Nick didn't need any more prompting. He got up from the bed with some difficulty and went to his closet to get his swimsuit.
Elisabeth sat on the bed, kicking her legs playfully like a little girl, and stared after Nick as he slowly began to pull off his t-shirt and dress pants so slip into his swim trunks.
"Do you mind not staring at me like that?" Nick protested over his shoulder. "You're making me feel awkward."
Elisabeth laughed and continued to toss her legs playfully. "It's not like you've got anything I haven't seen before, and that muscular ass of yours is total eye candy."
Nick blushed, but there wasn't really time or reason to protest. He pulled his white briefs down his legs, tossed them into the laundry hamper and pulled on his pale green trunks on as quickly as possible. They had a strip of blue hibiscuses printed in the sides of the leg and looked like the sort of thing a surfer might wear to the beach in good weather.
Elisabeth whistled as the trunks slipped over her brother's bottom.
