Down a Peg

Alex couldn't believe what was happening to him. It amazed him that even with what she was doing to him she was trying to calm him. Part of Alex was painfully aware that this would become a regular thing. He could hear the lust in Sarah's voice and there was no denying that he'd be stuck as her favorite sex toy from now on. The thought was a bit scary but Alex couldn't deny that some part of him was painfully turned on by the whole thing.

When her thick toy pressed against his prostate all hell broke loose and he arched his back, groaning against the gag as his big sister found his sweet spot. He was blushing like crazy after that but he was a lot less resistant at this point. His cock was liberally dripping precum onto the bedsheets as well, a tell tale sign of his body's reaction to her strapon. He wasn't just beautiful, he was extremely sensitive in all the right spots to make a proper sissy for his big sister.

Alex mumbled something against the gag when Sarah asked him a question but there was no way to understand what the answer might possibly have been. She did understand Alex when she sucked on his earlobe. You couldn't tell what someone was trying to say through a ball gag but even a stifled moan was still pretty obviously a moan
 
"Ohh yeah..." Sarah rasped out, smacking Alex hard on the ass as she thrust her hips deeper, pushing the strap on further into his tight hole. Leaning up, she fumbled with the buckle on her brothers gag, letting it fall around his neck, the panties freely falling from between his lips. "Is that better sweetie?" she whispered, smacking him on the ass as she slid her toy back in and out, falling into a steady, smooth rhythm, avoiding his prostate again for now. She'd make him work hard for that again.
 
He whimpered a bit as she thrust deeper. Alex felt so full with that thick toy plugging up his tight rear. He did his best to hold still when he felt her messing with his gag, very much wanting her to take it off and not wanting her to decide not to because he was squirming. "Uh huh..." He managed, taking a nice deep breath as the gag was removed from his mouth. When she struck his ass again he let out a soft gasp, groaning as she began to ride him again. Sarah was clearly going to be a rather rough lover for her cute brother. He bit his lip as he realized that she was doing this wrong. It sort of annoyed him that he'd come to realize there was a right. If she was going to fuck him she ought to hit his prostate, at least then he might enjoy himself...
 
"Come on little girl. Tell me what you want." she whispered, leaning down close to his ear and giving it a quick nibble, her lips sliding across his cheek as she rose up to look at him, still thrusting into his anus. "I'm just breaking you in right now Alexis, wait till I have you nice and loosened up, then we'll have the real fun...." she grinned, giving him a wink. "So go ahead, tell me how you want it, want it bad."
 
Alex bit his lip as she whispered into his ear. He didn't want to have to beg for something like this but his cock was absolutely throbbing as she nearly missed his prostate every time. He whimpered as his big sister towered over him and rode his ass casually, informing him that he had to ask her for more. He flushed red as he looked over his shoulder at her. "Please Sarah... Could you maybe try hitting more around here..." As he spoke he pressed back against her so the toy would rub his prostate. The second he did it was like an electric shock shot through the poor boy, causing him to gasp loudly. He may have wanted to be careful what he wished for.
 
Sarah grinned wildly at the gasp. She reached down and roughly pulled his head back by the hair. "Was that enjoyable sweetie? Do you like it when your sister does it like that? Hmm? Tell me how much you like taking it in the ass Alexis. Tell me how much you want to feel that again." her soft voice turning into a low growl at the end. "And then, I want you to lay back for a moment. I'm not going to peg you just now, just lay back and get used to the feeling of a strap on sitting in your anus." she whispered, pressing her flat stomach and breasts up against him.
 
He whimpered a bit as Sarah pulled his head back, struggling to imagine how Sarah had turned out like this. He'd never imagine that his big sister would turn out so dominant. "It felt really good..." He admitted, biting his lip softly. "I think I could learn to enjoy getting fucked in the ass... I really like it when you hit that spot..." He said, not really having looked into pegging enough to know that the sweet spot she'd just hit had been his prostate.

When she told him that she wouldn't fuck him just yet he found himself pouting softly. He lay down like she asked him to, his soft chest pressing down against the sheets. He did jump briefly when his cock brushed the sheets, damn was his pretty dick ever sensitive! "How long do I have to wait?" He asked, struggling to sit still. Those silky sheets felt so good, he was having trouble not trying to rub his cock against them.
 
Sarah smirked. "You'd better sweetie." giving her hips a light thrust forwards before sliding the toy out of him entirely without pegging his prostate again. "And when I think you've earned it, I'll even let you cum from having your tight little ass filled." She giggled, unhooking the strapon and letting it fall to the floor. She moved Alex into a sitting position and slid into his lap, stroking his face lightly. "Now that I have your attention.... You're my sister. Understand? You're going to be dolled up at all times, in whatever outfits I decided appropriate for you. You're going to sleep in nighties, learn how to curl your hair, apply make-up yourself, and conduct yourself properly when in public as a young lady. Understand?"
 
He whimpered when she pulled out, still hard as a rock. He didn't complain when she slipped him into a sitting position, though he was a little unsure of where she was going with this. When she sat on his lap there was basically no way to avoid the possibility that his cock would either be rubbing against her pussy or ass. He gave a gentle sigh when she took her seat, softly wrapping his arms around her as she stroked his face and spoke to him.

"Alright Sarah..." He said softly, feeling rather defeated. His breath was still a bit heavier than normal. The poor thing must have been horny as fuck. "Just one thing... What do I do about this?" He asked, gently reaching down and pressing a single fingertip to the head of his cock, practically jumping when he did.
 
"I would advise a cold shower." she whispered, before pressing her lips to his roughly. She wasn't about to help him get off just yet. Her arms slid around the new girl, delicately undoing her corset laces. "And I mean that sis. If I catch you masturbating without my permission, I'll lock you and your penis up and keep you on the edge of release all night." she smirked at him, loving any chance to assert her dominance over the boy. "Now what is your name sweetie, and what's your sex?" she added, voice soft as she pulled the corset away from his body, it's tight lacing leaving imprints in his skin.
 
For someone who just advised a cold shower she certainly didn't kiss like she was trying to ease his libido. Much as he was pissed at her right then he still found it hard not to kiss his big sister back. When she threatened to lock his cock up he briefly considered whether or not she'd seriously go through with something like that. In the end he decided to try his best to never find out whether or not she actually had a cage picked out for his cock. "I'm Alexis. Don't you even recognize your little sister, Sarah?" He asked, sighing as she stripped off the corset. He slipped the thigh highs off too, not really considering that she might get mad at him for doing so without permission. Considering that he immediately looked for a nighty to wear she sort of had a choice between punishment or seeing her little sister try on some more of her new clothing.
 
Grinning, Sarah slipped out of the room and hurried to her own closet, quickly pulling out tonight's outfit, sliding a sexy little pleated chiffon babydoll and thong onto her inviting frame. Black, sheer, and leaving little to the imagination, she grinned wildly, practically skipping back to her new sisters room. "Well, have you decided what to try out tonight?" she called out, as she turned into the room, eager to see what sexy little number she'd decided to try out.
 
Sarah returned to find her sister struggling to find a way to hide her still hard cock beneath her pink nightie, for once in her life lamenting that she was actually fairly hung. Not that extended periods of time in a cock cage were an appealing alternative. In the end she had to give up upon her big sister's return and just let her boner shamelessly lift the front of her nightie. "It won't stay down..." She said with a little pout, fully aware that the silky fabric caressing her cock wasn't going to be the least bit of help
 
Pulling Alexis close, Sarah kissed her softly on the lips. "You're adorable Alexis." she whispered, pushing a strand of hair behind the girl's ears. She let out a soft sigh and gave her a hug. "Ok fine. I guess you deserve a bit of a reward for being such a pleasant little girl for me." She pushed Alexis down on the bed, giving her another kiss on the lips, and trailing kisses down her neck, her hands scooting up Alexis nightie and pulling down her panties. "Going to continue being such a good little sister?" she whispered, looking back up at her with a grin.
 
Alexis realized that she should still be pissed at her big sister for this but by now Sarah had probably long since realized that Alexis couldn't bring herself to pull away when Sarah's lips met hers. She kissed her back softly, smiling when Sarah called her adorable. She had to admit, even with her cock straining against her panties she was downright adorable. Alexis gasped as she was pushed down on the bed, squirming beneath her big sister's kisses but certainly not trying to get away. When her panties were slipped down her cock popped up quickly, long, thick, and hard as a rock. "If you keep being so nice to me I'll think about it." Alexis said, returning her big sister's grin.
 
"I think you'll find I can be a lot more persuasive than you." she said with a grin, her lips on Alexis again, tongue invading the others mouth for a moment before pulling away. "Now, if you're going to behave and be a proper sister, perhaps I can do something about that little problem you are having hm?" Her lips back to Alexis' before she could manage a reply. Pulling back once more she batted long, think eyelashes at the girl before slowly taking Alexis rock-hard shaft inside of her, gasping softly as she moved further down.
 
Sarah was probably right about that, not that Alexis had the chance to comment on any of that before her mouth was invaded by Sarah's tongue. There wasn't much to do at that point but hold on for the ride. She was about to speak up when given the chance but her big sister silenced her once more. What came next drew a surprised moan from the poor sissy. Alexis was hoping for a handjob, maybe a blowjob if she got lucky. What she hadn't expected was for Sarah to take control and start riding her cock. Alexis wrapped her arms around Sarah, groaning as her sizeable shaft slipped into her big sis.
 
"That's a good girl." Sarah cooed out, stiffing a soft moan as she slowly slid herself down onto Alexis shaft, moving every inch into her wet, waiting sex. She sat still with the young boys member fully inside of her deliciously stretching and filling the woman. "Now..." she said with a sigh, pulling herself close and sucking on Alexis earlobe, taking her new piercing into her mouth before letting go. "About that little, we'll see comment....I think your finding this a lot more appealing than the idea of a cock-cage?" she whispered, her voice lusty, as she started to ride her agonizingly slowly.
 
Alexis groaned as his big sister sank down onto his cock. For such a cute little sissy he was nicely hung and filled her wonderfully. His hips lightly ground against hers and she could tell how badly he wanted to fuck her. His eyes went wide when she mentioned a cock cage. He had no doubts that she owned one and that it'd be agonizingly small for someone as well endowed as him. "I'll be a good little sister. Please don't put me in a cock cage." He pleaded, his voice quivering more from pleasure and lust than fear, though one look at the boy could tell you that he'd do most anything to avoid that cock cage.
