Kirsten Channing grinned in surprise and sat upright in her lawn chair, nearly spilling her wine cooler. "Did you see how Alex was checking you out?" she said in an excited voice as she turned to her left.
"You're out of your mind," Erin Armstrong told her friend "more likely he was checking you out." She twisted in her seat and demurely pulled her light green mini skirt down towards her knees.
"No, I'm not. But I guess I can't blame him for looking when you're sitting there with no bra wearing a tight tank top and that short skirt." Kirsten countered with a chuckle.
Erin laughed. "So it's my fault for being braless then?"
"No. All I'm saying is that a guy would have to be blind to not notice you right now considering what you're wearing, and your brother is no different." Kirsten explained as she looked down at her friend's chest and grinned. She had always been envious of Erin's full breasts, and then there were times that those feelings had strayed towards lust, but she was always reluctant to act upon those urges. Instead, she masked it as envy and admiration.
Erin took a gulp of her wine cooler and slid down in her chair next to Kirsten's. She didn't want to sound too defensive or continue the conversation because she knew that Kirsten was right. For a little over a year she had noticed that Alex had begun to look at her in a way that she assumed brothers don't normally look at their sisters. It was more than looking. Actually more than often it was blatant leering. At first Erin told herself she was imagining it, but shortly after Alex turned eighteen his furtive glances at her turned into lingering stares -- especially as she bent over in front of him, or when she wore certain tank tops or short skirts. She could no longer fool herself into thinking anything other than she was the object of Alex's lust. At first this realization upset Erin and made her very uncomfortable. After all what was happening was incestuous, and forbidden by any the status quo of any civilized society. Soon she consoled herself by rationalizing that Alex was simply looking, and it was perfectly normal for teenage boys to look at girls, perhaps even their sisters. At that stage in their life (if not well into adulthood) they are ruled by their hormones and not always in control of their lustful tendencies she reminded herself.
"No way," Kirsten continued "he was definitely gawking at you. Besides, Alex doesn't like blondes. He likes brunettes with big boobs, like you."
"And just how do you know what my brother's type is anyway?" Erin asked with a nervous laugh.
"Randy told me." Kirsten explained.
Intrigued, Erin sat her glass on the table between the chairs and turned to face her friend. "Okay... and just how does your brother know this?" she demanded.
Kirsten gave Erin a smug grin as she brought her glass down from her mouth. "He told me about a conversation he and Alex had a while back. He knows I think Alex is hot, and he said I'd stand a better chance if I dyed my hair brown... and padded my bra." her voice faded out as it filled with regret.
"Oh, don't listen to him," Erin said, trying to sound reassuring "you're plenty big up there," She took a quick glance at her friend's chest and lowered her gaze to her glass on the table, then picked it up "what does Randy know about what's in your bra anyway?"
"Plenty. He's seen them." Kirsten divulged without couching her words, not daring to look at Erin.
"What?" Erin exclaimed, incredulous "He's seen your tits?"
Instead of replying Kirsten simply gave her friend an embarrassed smile and took another drink of her wine cooler.
"Holy shit, Kirsten! I can't believe you just told me that!" Erin blurted out, wide-eyed.
Kirsten shrugged and forced a smile. "It's no big deal. It's not like we go all the way or anything. It seems kind of natural really. Just don't tell anyone I told you though, okay? Promise?"
Erin nodded, still quite unable to digest her friend's sudden revelation. If she were to be perfectly honest she would have admitted that there had been times when she wondered what it would have been like for Alex to feel her. She knew from the look on his face as he stared at her that he wanted to, and there were times when Erin had considered letting him. Still, society's mores had prevented her. As her brother's leering had grown more overt Erin found herself enjoying it. She loved the attention and the power it gave her. Soon she began purposely wearing clothes while at home that Alex seemed to enjoy seeing on her, especially tops and skirts that showed more of her body than she would normally feel comfortable displaying in public. She began dressing provocatively in hopes of enticing her younger brother, especially when their parents weren't around -- taunting him in hopes he might escalate their game to another level -- something she never dared do.
"You mean you and Randy mess-around?" Erin asked, seeking clarification and hoping to hear some titillating accounts from Kirsten.
Kirsten shifted in her chair feeling uneasy "Ah... yeah... I guess... just touching... you know. Nothing major." she explained.
Erin nodded as she listened and thought of her own brother feeling her. She could feel her clit twitch and began getting wet at the thought of Alex running his hands over her willing lithe body.
"You must think I'm a horrible slut." Kirsten mumbled as she stared at the glass in her hands.
"NO!" Erin exclaimed "I'm surprised, that's all. But I don't think badly of you, honestly, kirst!"
Kirsten gave Erin a relieved smile.
"Besides, Randy's really cute. I can't blame you." Erin added with a giggle, trying to reassure her friend.
"Well, so is Alex," Kirsten countered "What would you do if he tried to feel you?"
Erin stared off at the setting sun over the river and contemplated her answer. For a long time she had known that if her brother had crossed that line she would not stop him, but admitting it out loud to someone was difficult.
"I don't know," she mused "I might let him. But that's just 'cause I've had too many wine coolers."
The girls laughed aloud in unison at Erin's reply, then gave one-another a serious glare.
"Really -- you'd let him?" Kirsten queried.
"I don't know," Erin explained "you're right about how he looks at me, and I'd be a liar if I said I'd never thought about it..."
"So...?" Kirsten prodded.
"I just don't know, Kirst. What if I'm wrong? What if mom and dad catch us? It's not something you jump into, you know?"
Kirsten gave her friend an empathetic nod. "I know," she began "but you don't have to worry about whether or not he's interested. I've seen how he looks at you, and I bet you have too. You know he's interested, Erin."
Erin nodded in agreement.
"So," Kirsten continued "just be careful so your folks don't find out. When will they be back?" "They're in Vermont celebrating their anniversary. They'll be back on Tuesday." Erin explained.
"Then that gives you three days," Kirsten told her "that's more than enough time."
"For what?" Erin asked.
"To have some fun with Alex!" Kirsten declared.
"Oh geez, I dunno, Kirst," Erin countered "this seems so sudden."
"Sudden? How long has he been looking at you like that?" Kirsten inquired.
