The characters who are sexually active in this story are college juniors, so 21--22 years old. The younger person mentioned is 18 years old.
Giovan desired his sister, but she didn't desire him. The cumbersome equipment he carried between his legs had not gone unnoticed by Giselle. And while she may have been a little curious about it, the idea of having sex with him was alien to her. He knew this, or rather he feared it. He also knew--he was absolutely convinced--that if he could just get his big prick into her hot little snatch she would become his for life.
Gisella--perversely, in his view--had eyes only for his roommate, his gay roommate, Jeff, who only encouraged this infatuation by flirting with her every time she visited their room. Jeff had asked Giovan not to tell her he was gay because he didn't want Gisella to "go fag-hag" on him. Whatever that meant.
Jeff, on the other hand, had cultivated a bit of a crush on him, one that had intensified a few weeks before when Jeff came home one afternoon in time to see Giovan just finish masturbating to a picture of Gisella.
Jeff started, stared, then said, "Please tell me that's a picture of me."
Giovan sat back on his heels, his cock arcing up between his thighs, slowly going soft after his orgasm. He was not shy about his dick; no, he was rather proud of it. He had every right to be. It was long, thick, and veiny--just like the ones in the porn stories. And his balls: they were big, they were hairy, and they hung low in their sac. Were they as big as lemons? Of course not. No one has balls that big. Don't be stupid. The cum on his chest was sliming its way down his abdomen.
Giovan wore his slightly sneering grin. "Sorry, loverboy. Not this time." He held his cock near the base with one hand and squeezed the head with the other hand, eking out a final dribble of white jism. He wiped it up and smeared it into the hair on his chest. His gleaming prick (coconut oil) quietly settled down between his thighs and Jeff finally looked at Giovan's face.
"Jesus," he opined.
A smirk tweaked at Giovan's mouth now. "You wanna suck me off sometime?"
Jeff's expression opened up for a moment and his mouth opened slightly, but then, just as quickly, his eyes hardened and his mouth became a firm line. He turned away to put down his bookbag. "Don't be such a fucking asshole."
Giovan's smirk disappeared. "Sorry, Jeff. I was just teasing." After a moment he added, "do you want to lick the cum off me?"
He just barely ducked the book Jeff hurled at him.

It was a clear spring day on the quadrangle lawn. The sun was gentle, the breezes mild, and the pleasant noise of young people talking and playing catch or frisbee completed the scene. Giovan reclined with a textbook, but his mind was running through a fantasy in which his sister was desperately sucking on his knob...because...because...because she had become a "cumpire", and Giovan was letting her get sustenance from him because he was a good and noble brother. Oh, and he had just killed Count Jizzula, the cumpire who had transformed Gisella into the ejaculivorous beast she now was.
Or maybe, he thought, maybe it was a "Nosferwadtu." hmmm...
She was sucking fiendishly hard now. Giovan sat up to adjust his dick surreptitiously: it had been pointed downward when he had started his fantasy, now it was straining painfully against the unforgiving fabric of his jeans.
"Hi."
"Whaa!"
The girl blinked at Giovan's startled cry. "Sorry! I didn't mean to scare you. You must have been really zoned out."
"Uh, yeah. Kinda."
The girl smiled at him but also to herself. She had seen what he had been trying to do. She had brothers, she recognized the "adjustment" when she saw it. She was also keenly aware of the prominence of what he had been trying to adjust in his jeans. She arched an eyebrow in contemplation.
"I'm sorry to bother you," she said, "but one of my friends over there," she jerked her thumb over her shoulder, "has this idea about you. I don't really agree with him. Long story short: can you settle a bet for us?"
Giovan frowned. "A bet?"
"Yeah. See, the thing is my friend, Eric, over there, he thinks--"
"Who?"
"Eric. Over there."
Giovan looked past her leg at a guy and a girl sitting on the lawn a few yards away. The girl was dull-eyed and sort of caved in on herself, but the guy had an alert and pretty face.
..."pretty"? Where did that come from?
The girl in front of him began talking again. Giovan was only aware of her bare legs in front of him, of her tight cut-off jeans, of how they drew the eye to the juncture of her inner thighs, of a slender body with jutting breasts, and a fine, narrow oval face framed by glossy dark brown hair.
"So are you?"
Giovan tried to piece together what he hadn't been paying attention to....and, nope, not a fucking clue.
"Am I what?"
The girl grinned. Giovan thought it was a lovely grin. She, in turn, had been looking him over and liked what she saw. He had a lean athletic figure, curly locks of flaxen hair, a handsome face, and large graceful hands.
"I asked if you're gay."
"--oh."
"Because Eric over thinks--he hopes--that maybe you are."
"Oh, well, I'm afraid he's out of luck."
She grinned again, but now a different light was in her eye.
"Good."
Giovan cocked an eyebrow of his own. "Good?"
Her grin drew into a mouΓ© as she continued to look him over. She didn't answer him. She looked over her shoulder and yelled, "I was right! You guys owe me a beer!"
Turning back to him she thrust out a hand. "Eve."
He took the hand. "Giovan."
