Trevor went through her instruction. This was actually really cool, he decided. Relaxing, calming. At the end of it, he felt more… balanced, he guessed.
“Thanks, sis.” He said, accepting a towel from her and mopping his forehead, “I’m liking this.”
“Me, too! I didn’t really think I’d like teaching it as much as I do, but you’re a good student. Quick learner.”
He took a seat on the couch and checked his phone, which he’d remembered to silence this time.
“Trev?”
“Hmm?” He grunted, responding to a message from Mary.
“I don’t want to impose, but, well… I was hoping that I could use your computer again. If it’s not too inconvenient.”
Trevor stiffened, but tried not to show it.
“Uh, yeah… sure. I’m gonna shower and watch some TV, so whatever.” he said, his eyes on his phone, though he wasn’t really looking at anything.
“Thanks.” Stacy said happily.
Trevor watched out of the corner of his eye as Stacy’s ass wiggled away out of the room. He gave it a few minutes, and then showered. It was only as he got out that he realized his mistake. He hadn’t actually brought other clothes in with him. He wrapped a towel around his waist and padded softly to the door of his room. Maybe Stacy wasn’t using his computer yet. The door was mostly shut, but cracked. He raised his hand to knock, but then a tingle went down his spine. Was she…?
As soon as the thought entered his brain, he knew he had to know. It was just like the morbid curiosity that had prompted him to open those tabs. He just… had to know. Stealthily, he placed his finger in the door’s crack and eased it open just enough to see. And, oh, did he see.
Stacy was at his computer, pushing a thick, pink dildo into herself. Trevor bit his lip. Oh, shit! His desk was essentially just a table, so there was no back to hide what was happening underneath. The rise of the dual-monitor setup ensured that whoever was behind the desk could not see the door, but anyone at the door could clearly see what was happening beneath the desk. Stacy’s spread legs were quite visible, as was her busy hand, working the toy in and out of her sexy pussy. He could hear her soft moans of pleasure as she fucked herself slowly. He felt his own hand rubbing his cock through the towel, looked down, and quickly pulled it away. Fuck, this was wrong! He was looking at his first real pussy, and it was his own sister’s!
He tore himself away from the door, and hurried off silently, creeping down the stairs, and threw himself down on the couch. His cock was stiff, tenting the towel. He shut his eyes and breathed, but all he could see was a pink dildo, held in long-nailed fingers, being stuffed into a wet, sexy pussy. Jesus, he was the worst fucking brother!
The sound of the bathroom door clicking shut just upstairs drew his attention. Stacy was finished. Stacy was finished masturbating with his computer. He could get dressed. Yes, dressed. He quickly went up to his room and shut the door, locked it, and went to the computer. He ran his hand across the seat. It was wet. He’d just scooped up his sister’s pussy cream on his finger. Oh, God! He wiped his finger on the towel, but instead of putting the towel on the chair, he paused, and with a trembling finger he scooped up more of the wetness, and brought it to his mouth. It had a sweetness to it, but didn’t really didn’t taste like much.
He sat in the chair; the towel protecting him from the wetness, and took the mouse in his hand. There was one minimized browser window. Shit! He hovered over it, left-clicked, moved the mouse to “close” then to “maximize”. He had to know. He clicked.
The video was titled, “Beating my Brother’s Boner.”
He put on the headphones and clicked play. This wasn’t a fauxcest video. Chances are it was just a couple roleplaying, but it was certainly homemade. The camera was someone’s phone, set to the side on a table. The couple was young, probably about the same as him, if he had to guess. They did not show their faces. The young man sat on the couch, and his topless “sister” kneeled before him.
She poured lube from a bottle into her hands, and slowly stroked the man’s erection, getting it slick and shiny. She worked both hands up his long shaft, then used one to jerk on the head of his cock, and the other to stroke up and down his rigid pole. Trevor’s hand found his own pole and stroked. The motion of the girl’s hands was hypnotic. His eyes glued to the screen, he matched the rhythm. The “brother” moaned and gasped as his “sister” stroked.
“You like that?” She teased him.
“Yeah.”
“Do I do it better than your girlfriend?” She asked, hotly.
“Oooh, yeah. Don’t stop!”
“Am I hotter and sexier than she is?”
“Yes!”
“She doesn’t suck your cock, does she?”
The man moaned, and somehow Trevor knew he was shaking his head in the negative.
“You could let me suck it,” the girl teased. “You could let your big sister suck it for you.”
“Oh, shit!” the man exclaimed, and his cock twitched wildly in the girl’s hand.
The man grunted, and Trevor saw a hot spurt of cum between the girl’s fingers as she worked the head of his cock. He continued to groan and buck his hips as the girl milked the cum from his hard penis, leaving her hands a sticky mess. She leaned in and sucked the head of his cock, swiping her tongue around the crown to lick up the gooey semen. Trevor’s own cock exploded over his hand. He fumbled for the edge of his towel and wrapped it around his spurting cock as the guilty pleasure flowed through his groin. The girl in the video giggled and slowly milked more cum from her “brother’s” cock, licking it up sexily.
Chapter 8: Lessons
Trevor, dressed in shorts and t-shirt, laid back on his bed watching TV. Well, the TV was on, but he wasn’t really watching. He wasn’t really doing much of anything. He was thinking about the video and feeling guilty. He’d done it again. He’d intruded on Stacy’s private fantasy world. This time, he’d even jerked off and cum to it. Jesus, why had she left that stupid browser open? The thought stopped him. Why had she left the browser open? It wasn’t like Tracy didn’t know the difference between close and minimize. Had she done it on purpose? Had she left it open for him to find? It certainly appeared to be the case. Why else?
She’d meant for him to find it. Teasing him would certainly be something that Stacy would do. She might just be doing it as some kind of sick joke. That would be entirely like her. She’d do it just to fuck with him. Like the time she replaced his shampoo with honey. It wasn’t malicious. It was just the relationship they had. Good-natured ribbing. That was all it was, he was sure. A knock at his door broke the thought.
“Come in,” he called.
Stacy opened the door, dressed in her new bikini. Trevor did his best to keep his eyes on the TV, but she posed with one arm against the doorframe, legs slightly spread. The keyhole top revealed deep cleavage, pressing her breasts together like an offering.
“Feel like hitting the pool with me?” she asked. “It seems a shame to spend such a beautiful day inside watching TV.”
