Trevor fought with his hormones, but decided it was the right thing to do. Stacy was just being a jerk with the porno thing, after all. She was screwing with him, to see what kind of reaction she could get, probably laughing to herself the whole time. He couldn’t let her win.
“Yeah, ok. Let me get dressed.” He said.
Stacy did not move from the doorway. She watched him expectantly.
“Um, a little privacy pervert?” He said jokingly.
“Oh, right,” she laughed, “can’t divulge the location of the family jewels. Someone might steal ’em.”
She shut the door. Trevor sighed and dressed in his swim shorts. He found Stacy outside, already in the pool.
“If you cannonball me,” she yelled, “I’m gonna pants you.”
Trevor took the stairs into the pool, and made a few easy laps back and forth across its length, while Stacy floated on her back, soaking in the sun. Trevor wondered if her boobs helped keep her afloat, then chastised himself for thinking about her tits again. For a while, they just relaxed in the water, then decided on racing from one end of the pool to the other several times. Trevor could tell that Stacy was a bit surprised at how evenly matched they were.
Eventually, they tired of the water and laid out on the loungers to dry off. As they lay in the sun with their shades on, Stacy spoke up.
“So,” she said, “I hear you and Mary haven’t been…intimate.”
“Intimate? Wow, Stac. That was a whole sentence without the word fuck in it.”
Stacy laughed, saying, “I was trying to be nice, dumbass. Ok. I hear you haven’t fucked your girlfriend yet. Is that better?”
Trevor blushed, but he’d asked for it.
“Why was Mary talking to you about us?” he asked.
“We were girl talking, of course. Girls talk about dicks and clothes.”
“Hey, thanks, by the way. It was really cool of you to include her like that. She doesn’t have a lot of, well, regular friends. They’re all those churchy girls, and I’m sure they’re not talking about dicks and clothes. I know you didn’t have to be so nice, so I appreciate it. Most big sisters wouldn’t even try to get to know their brother’s girlfriend.”
Stacy reached out and touched his shoulder, genuinely touched, even if his supposition for why she was including Mary so thoughtfully couldn’t have been further from the truth.
“She’s a sweet girl.” Stacy said, then asked, “So, why haven’t you boned?”
“You’re weird.”
“No, I’m just embarrassed to have a studly brother that’s still a virgin. I’m thinking about my reputation. Tara was telling me how hunky she thought you were.”
“Tara?” he asked, thinking of Stacy’s statuesque blonde friend. “The last time I saw Tara, she called me a drooling pervert sicko.”
“Well, time has a way of changing one’s perspective, I guess.”
“In my defense,” Trevor said, “her bikini was way too small.”
“So was her boyfriend’s dick.”
They shared a laugh at the joke.
“You’re avoiding the question.” Stacy said, finally.
Trevor sighed. She would not drop it.
“Mary’s a good girl. She’s got all that Jesus in her head from her mom.” He said.
“Jesus isn’t what’s stopping her.” Stacy said.
“What do you mean?”
He rolled over onto his side, curious.
“She’s afraid, trust me. I can see it.”
“Afraid? Why?”
Trevor felt like he was being baited, but Stacy was discussing sex, and the prospect of something that might lead to him having sex with his girlfriend made any reservations about discussing sex with his sister irrelevant.
“Let me divulge the solemn secrets of the female gender to you,” she said, “and remember, these are closely guarded. To discuss them with a man breaks all kinds of rules, so I could totally lose my vag-club card by telling you.”
“Sounds serious.” Trevor joked, but he was genuinely curious. Of course, he’d read plenty of things on the internet about girls, what women want, the kinds of things every guy wants to know more than anything else.
“The thing about most girls,” Stacy said, “is that they’re actually a lot like guys when they think about sex. Especially when a girl hasn’t done it before. They get scared that they’re going to do it wrong, or that they’re not going to be good enough. They think that guys have these lofty expectations about what a girl should know, like kissing or touching, or giving a good blowjob.”
Trevor thought about the video. “Let your big sister suck it for you,” he heard the girl’s voice say, and he felt his dick getting hard.
“That’s stupid,” he said aloud. “Why would I expect her to know about stuff that she has no experience with?”
“It’s just the way people think. Let me ask you this: Are you afraid that you won’t do it right, or that you won’t be good enough? Don’t worry. It’s normal. Of course you are.”
There was no need to answer. She continued, “everyone is worried about that. But really, what were you good at the first time you did it? Hell, I’ll bet you couldn’t even jerk off right the first time. I know I couldn’t.”
“Ok, that makes sense.” He conceded, unable to stop himself from thinking about Stacy shoving a dildo into her pussy.
“It’s like anything else. You learn with experience.”
“Kind of hard to get experience,” he said, “when your girlfriend won’t let you.”
Stacy grinned and felt her pussy juice up. It was exactly the answer she wanted. Bait set. Spring trap.
“What you need,” she offered helpfully, “is to know exactly what works a woman up, so that she won’t say no. She’ll want it more than you do. Now, what you have going for you is that you already have most of what it takes.”
