Sister's Anatomy Lesson Chapter 5
***********************************************************************************************************************************
The moment the door shuts, Maggie whips her head back, grinning like a Cheshire cat.
Seeing what is perhaps his one, and only opportunity to reason with the brat before him, Alex gulps, and puts on his best puppy-dog look. "Maggie, PLEASE. This has gone too far" he pleads.
"Hmmm..... Nah." She says dismissively, her hands continuing their assault. With one hand at the base of his cock, holding it upright and keeping it firm, the other gently traces the length of his shaft. Up and down and up and down.
Alex shivers. "Ughhhnnnn... Maggie please..." Alex moans, the conflicting feelings of shame and arousal making his stomach churn. Her finger tips masterfully teased his boyhood, and she wasn't even stroking it. He began to feel like he might lose his mind!
"Wanna hear a secret?" Maggie whispers, leaning in. "You're not the first boy that I've seen." She giggles. "Or played with."
Alex's heart drops.
"W-wait. Maggie?? W-who was it?"
"Lots of boys," She smirks, her finger continuing its gentle caresses. "Me, and Sarah and Connie have a bit of a club going. You gotta get the boy trouble"
Alex's blood runs a bit colder. He did NOT like where this was going, even before he could begin to piece it together. "Your friends from Girl scouts?"
"Mmhmmm," Maggie hums, her fingers continuing their exploration. She holds his erection firm, while her fingertips begin tracing the ridge of his head, around and around. Alex's body trembles slightly, and he can't help but let out a shaky groan. "If you catch them doing something naughty, or if we trick them, we threaten to tell teacher, or their mommy and daddy."
"UNLESS." she pushes his erection down with her fingers, letting it fling back upwards like a catapult "he shows us his thingie. But then we have more ways of getting him in trouble! So, we can play with them wheneeeever we want."
"Ohhh god" Alex whimpers, his eyes rolling back slightly. This.... This was the most devious thing he'd ever heard in his entire life, yet somehow it was also the most aroused he'd ever been. What ever happened to the Maggie that would sneak an extra cookie, and call THAT being bad?
"Y- you're a monster..." Alex stammers.
"Hehe, nooo. I'm Maggie." She grins, her hands wrapping fully around his cock, and slowly stroking it up and down. "But you're my favorite boy to play with! You're older, your thingie is a lot bigger. Aaaand you're a lot more fun to bully."
Alex lets out a shaky breath, his cock feeling like a steel rod between his legs, and his mind a melted mess of conflicting emotions. On one hand, he hated his little sister with every fiber of his being, and wanted nothing more than to smack the little brat, and teach her a lesson for humiliating him so thoroughly. On the other hand... well, his dick was loving the attention.
"The girls will looooove playing with you big bro!" She says in a sing-song voice.
This was bad. This was really really bad. He had to get out of this and NOW if he wanted to save himself from a lifetime of being tormented by his little sister and god knows who else.
"MAGGIE, I'm being serious, stop. NOW" He demands, finally mustering up the courage to stop this little show. He begins to sit up in the bed, his anger momentarily overpowering his lust, as he reaches down to smack her hands away.
*Squeeze*
Alex's eyes widen in shock, his entire body seizing as if he'd been electrocuted, as Maggie applies pressure to his most delicate area. The pain wasn't overwhelming, and dissipated as quickly as it had occurred - but his balls remained firmly in her grip. His little sister literally had him by the balls.
"Mommy was right, these ARE delicate!" She muses, her vice like grip increasing once more, just enough to remind the boy of how much power she had right now.
"Lay. Back. Down." She growls, and his body complies on autopilot--not even mustering a comeback. His back hit the mattress once more, and Maggie smirked triumphantly at his meek expression. "Good boy."
He'd never felt so powerless, and he didn't like it one bit. And yet...
*twitch twitch*
His cock continued to strain, a small pearl of precum leaking from the tip--betraying all of the effort he was putting into fighting, arguing, and denying how he felt about his treatment.
"Now will you be good?" She asks, her voice turning innocent once more.
"....Yeah." He responds defeated, his eyes glancing nervously back to the pair of balls in her small hands. He could take a hint.
"Great!" She exclaims, the evil tone dissapearing as if it had never been there. Her fingers release his balls, and return to their previous task, and the boy lets out a shaky sigh. "Let's have some more fun!"
"It's funny... Your thingie is even more red and angry than you are" Maggie points out, her finger gently tapping the head of his cock. The tip is shiny and slick with the fluid his body had been leaking. "Ewwww!" Maggie teases as a strand briefly drips from her finger.
"That's because... ah, because you're teasing it" He answers, his voice small.
"But I'm your sister!" She adds. "You're such a pervert!!!"
"Y- you're the one that's touching me!" He counters, his face reddening. His pace quickens as Maggie grips his cock by the shaft, and once more lets her fist rise and fall - masturbating the boy better than he does himself.
"It's educational" She defends, with a smirk. "Besides, if your thingie wasn't all hard I'd be bored and stop!"
"I- ahhh" Alex's voice falters as Maggie's other hand disappears below his balls, her fingers dip down to his balls, her fingers alternating between rolling them around and stroking the tickling flesh beneath his sack.
"You know, your boy parts
are bigger than I guessed they'd be." She comments, looking at his swollen balls curiously. "Maybe you didn't lie about being a big boy. Maybe you do shave your wiener."
Alex is despondent at this point, and the only response he can muster is a pathetic grunt, his mouth hanging open like a dog with it's head out the window, as he mindlessly watches her hand move up and down.
"But you're not a big boy right now. And your privates aren't private! You're MY toy now. That means YOU do what I say! If you're nice, I'll make you feel good. If you're bad, then I'll treat you bad."
"Maggie..." Alex pants, his voice hoarse and distant sounding like he'd just run a marathon. His breath quickens as his younger sister brings him closer and closer to the edge.
"But even when I can't hurt your balls, I'm the boss of you." She continues, stopping her stroking only to focus on Alex's mushroom-like head for a moment, making her brother's eyes roll back, before returning to her stroking. "If you try to stop me, I'll just tell mommy and daddy alllllll about how big brother touched me in a funny place while I was doing homework!"
Alex whines like a dog begging for a treat, his mouth falling into a frown and his eyebrows furrowing. Yet, despite how screwed he knew he was, despite just how helpless and angry he felt--his hips began thrusting up and down, meeting Maggie's hand in time with her strokes.
'This is your sister! She's blackmailing you! You're being dominated by a younger weaker girl! You're a black belt, push her off!' His brain screamed at him. All of these valid complains went unheard by Alex, as his subconscious took over the boy's inner monologue. 'Don't fight! Let her play! If you cooperate she might make you cum!' It informed him.
Alex had no idea if this was true or not, or if she would actually blackmail him after tonight's events, and he didn't care. His body had been wound up tighter than a spring, and now that the tension had finally snapped, his mind and body were on auto pilot. All he knew was that it would feel so so good to let go.
"Oh godddd...." He moaned, his eyes squeezing shut.
"Sooooo am I in charge?" She asks, her voice sing-song, and her grin cruel. Her hand moves faster and faster, the slick sounds of her working her brother's unwilling cock filling the small room.
"Yes.. You are.." He answers, his voice weak.
"Good Alex." She says with a smile. "Who's in control of your thingie?"
"You are."
"So, I can touch it as much as I want? And when I want?"
"Ye-e-esss" He hisses, his breathing becoming short and quick. "Pleeeease Maggie!" Alex whispers, his voice sounding defeated, and his body shuddering. He wasn't sure what was worse, his sister's constant taunting, or the way her fingers seemed to know exactly how to get his heart racing. He was getting close to the edge, and Maggie was taking full advantage.
"See big bro? That was fuuun. Now, shush, I wanna see what a big boy looks like when he-"
"MAGGIE, ALEX, DINNER TIME!" Their mother's voice booms.
