“Don’t you fucking cum yet.” Stacy hissed. “We have a long way to go. Remember your breathing.”
Trevor nodded and worked himself back into his mental space, which was complicated by Stacy’s hand gripping his shaft and sliding back up to fist his cockhead again.
“That was so exciting, wasn’t it?”
Trevor breathed and watched the girl in the video push her mouth down to the base of her brother’s cock. The man gripped her head in his hands and came into her throat. He watched the girl gulp and guzzle as the load of sperm rocketed into his sister’s clenching, wet throat.
“Do you want your girlfriend to do that for you, baby?” Stacy asked.
Trevor nodded as the next video began to play. It was the same couple, but this time the girl was on her back on the bed. Her breasts were bare, and the man was groping them as she hung her head off of the edge of the bed. He pushed his penis into her mouth and pumped it in and out. The soft sounds of the girl’s “gluk… gluk… gluk…” each time he pushed it in filled the room.
“That’s so sexy.” Stacy said. “Look at the way his big sister pleases his cock. It’s like her mouth is a warm pussy just for him. It feels so good, the way her throat accepts his penis like that. He’s so lucky to have that warm mouth to fuck whenever he wants, isn’t he?”
“Yeah…” Trevor said, gripping his chair as Stacy fisted his crown.
“You want your girlfriend to be able to do that for you, don’t you?”
“Yeah…”
“Do you think she will? Will her little mouth be able to take your whole cock like that while you play with her tits?”
“I… I don’t know…” Trevor said.
“Do you think I could take a big cock like that?”
“Yeah…”
“You’re right. I love that. I’ve had lots of guys fuck my throat just like that while they groped my tits. It’s so hot.”
Trevor’s cock leaked in her hand and she relaxed her fist on his head, stroked it back down to the base of his shaft. The man methodically used his sister’s mouth for long minutes, stroking his dick in and out, in and out, his hands mauling her breasts, twisting and slapping her nipples.
“You can’t put your cock in my mouth, though, can you?”
Trevor shook his head.
“Because I’m your sister, and it’s not right to fuck your sister’s slutty mouth, is it?”
“No…”
“He gets to put his cock in his sister’s mouth, though. How come he gets to do that?”
“He… She let him.”
“She doesn’t care that it’s wrong to suck her brother’s cock, does she?”
“No.”
“It’s exciting to do things that are wrong sometimes, isn’t it?”
“Yeah… ”
“You let your sister jerk you off, didn’t you?” Stacy asked.
Trevor shook in his chair and bit his lip as Stacy jerked him faster.
“Does it feel good, baby?”
“Yes!”
“We’re going to practice this a lot, so you can learn control. Do you want me to help you practice?”
“Yes!”
“Isn’t it wrong to let your sister jerk you off?”
“Yeah… ”
“But you’re doing it anyway, aren’t you?”
He nodded.
“Is it because you think your big sister is hot?”
“Yes!” He admitted.
“You don’t care that it’s wrong. You just want your hot sister to play with your dick.”
“Oh, fuck! Don’t stop.”
“Uh uh.” Stacy chided and slowed her pace. “Get it together. Don’t you cum in your sister’s hand.”
Between the stroking, and Stacy’s dirty talk, and the image of the couple on the screen, Trevor was fighting with everything he had not to cum. She rolled his balls in her hand and squeezed the base of his penis gently. The man exploded into his sister’s sucking mouth, burying his shaft in her throat, his hands squeezing her tits roughly. Trevor could see the girl’s throat working, swallowing shot after shot of her brother’s creamy jizz.
“She’s so good at that.” Stacy said, “You can see why he doesn’t care if it’s dirty, can’t you? He can use his hot sister’s mouth to cum in any time he needs it.”
“Yeah…”
“It’s not fair that he has his own mouth slut and you don’t, is it?”
Trevor groaned, his cock twitching in her hand as she resumed her stroking. The next video was the same couple, but this time the brother rubbed his cockhead on his sister’s wet, open pussy lips. The girl panted with excitement as he teased her cunt with his spongy crown.
“Fuck, that’s so sexy.” Stacy said, and drizzled more lube into her hands. “He’s going to push his cock into his big sister. Watch.”
Trevor watched the man push forward. His sister’s soft lips parted around his penis, and the sound of their shared moans of pleasure played from the speakers.
“Sometimes I wish I had a dick, just so I could feel how good a warm, slick pussy feels around it.” Stacy mused. “I love to feel cock in my pussy. It feels so good to have a hot guy pound his cock into me and treat me like his whore. If you weren’t my brother, I’d let you fuck your cock into me right now.”
“Oh, God!”
“Oh, my God, baby. You like that idea, don’t you? You little pervert. I already told you we’re not gonna fuck. You need to learn how to fuck your girlfriend, remember?”
“I… yeah…”
“Just out of curiosity,” Stacy said, as though the thought had only now occurred to her, “if you had us both naked on your bed, which one of us would you fuck?”
“I… Oh, fuck… fuck!”
“Which one, baby? Which pussy would you want to feel around your cock? Do you think your girlfriend would be fun? She’s so tiny and pretty. You could suck on those hard little nipples while you made her a woman. That’s so sexy.”
“Stacy… I… I can’t….”
“If you could fuck me, I’d let you grab my tits and pound this big dick into me as hard and for as long as you wanted. I love to fuck so much, baby. God, I wish you weren’t my brother so we could fuck every day.”
“Oh! Oh, God! I can’t… ” Trevor lost his battle. His whole body convulsed as Stacy stroked him off. He gripped the chair, white-knuckled, and unleashed one of the most mind-blowing eruptions of semen he could remember. The first shot hit Stacy square in the face, and she aimed his cock downward, her mouth open, eyes shining with excitement, so that the rest of his ejaculation sprayed across her tits. It soaked into her top, pooled between her cleavage, dripping down the valley in sluggish runnels of white.
“Oh, fuck, that’s so much, baby!” She said excitedly, jerking his spurting cock onto her tits.
When she’d finished milking the last drops of his cum, she pulled out her phone and took a selfie. In the photo, she held his half-hard cock in her hand. Her face, top, and cleavage were coated in semen. She showed it to Trevor.
“Wow! You did so good. I’m frankly surprised that you held out that long. There may be hope for you yet. You should get cleaned up. See you in the morning.”
She left Trevor coated in his own cum, sitting in the chair, unable to process what had just taken place. Stacy shut the door, padded quietly down the hall, and opened the door to her parent’s room.
Chapter 12: Shark Attack
It was Saturday morning, and Trevor stared through bleary eyes at his phone screen. He’d only just awoken, and texted Mary to invite her over, eager to see her new look in person.
“My mom is making me go to the church pantry to help this afternoon. 🙁 ” She replied, “Then we have to clean everything up and put away all the stuff the volunteers bring in.”
