Giving a fuck

Crystal grabs the back of your head, pulling your face farther into her crotch and forcing her cock deeper into your mouth. You sputter and gag, but she just moans in pleasure. _"That's it, take it all," _she says, as she thrusts her hips forward.

You feel her tip hit the back of your throat, triggering your gag reflex again. But with her hand firmly gripping your hair, you know you have to keep going. You continue to suck and lick with increasing desperation, trying to please her as much as possible.

"Oh..yeah that's right, be a good cocksleeve for your sister." Crystal's words send a shiver down your spine, as you realize the taboo nature of your encounter. But the thought also makes your cock stiffen even more, and you eagerly continue to bob your head on her cock.

You can feel her hand tightening in your hair as she moans louder, getting closer to her climax. "That's it, my little cocksleeve," she says, using the taboo term again. "Make your sister cum!" The words send you over the edge, and you shoot your load onto the floor beneath you, still riding on the wave of pleasure from servicing Crystal.

Crystal starts to thrust her hips forward, fucking your mouth like a flesh light. Each time she plunges deep into your throat, you feel a mix of pleasure and pain. But you don't care, as long as you can continue to please her. You reach up and grip her thighs tightly, trying to steady yourself as she picks up speed. You can feel your own cock getting hard again, the taboo nature of your encounter warming you up. Crystal moans loudly, clearly getting close to her climax. "Yes, YES!! Just like that," she gasps.

"Make your sister cum, bitch!" You redouble your efforts, taking her cock as deep as possible, and soon she shudders in release, filling your mouth with her hot cum. You greedily swallow it all, not realizing how big of a load her cock was making. The orgasm lasted for minutes before she pulls out of your mouth, taking a second to breath normally from that experience. _"Fuck..." Crystal exhales heavily, her chest rising and falling rapidly as she looks down at you. The forbidden thrill is still coursing through her veins, and she can't help but feel aroused by the scene in front of her. "That was intense," she says breathlessly, her voice laced with excitement. "Do you want to keep going?"_ she asks, her hand moving back towards her bulge, stroking it back to full length.

You could feel your body becoming hot again, being detached from that monstrously huge cock for so long. "Y..yes.." It was kind of hard to speak with cum still inside your mouth but you tried regardless.

"G-good because I wasn't going to stop regardless, ass up on the bed bitch!" She says, giving your ass a slap to show you she's serious. "I want to fuck something I've been waiting to fuck for awhile now." You quickly comply, raising your ass up on the bed and presenting it to Crystal. The excitement is palpable in the air as she positions herself behind you, her cock throbbing with anticipation. You wiggle your ass in front of her, encouraging her further into not holding back.

Tasting it was one thing but feeling it deep inside of you is going to be the hottest thing you've ever experienced. You feel a shiver run down your spine as you feel Crystal's massive cock pressing against your tight hole. The heat emanating from it is almost overwhelming, and you can feel your own excitement building as you anticipate the inevitable penetration. You push your hips back towards her, silently begging her to take you, her sheer size and power leaving you feeling turned on and submissive.

"Alright, slut you asked for it." You let out a gasp as you feel the tip of her massive cock pushing into your tight asshole, your body tensing with pleasure and anticipation. You can feel yourself stretching to accommodate her length and girth, a delicious warmth spreading through your body. She eases herself in inch by inch, the slickness of her shaft making the process easier, while at the same time, sending waves of pleasure through your body.

You moan at the sensations, deepening your sense of submission to her, and allowing her to fill you completely. Finally, she bottomed out, causing you to let out an involuntary cry as your body adjusts to her size. You reach out for her, trying to pull her closer, and begging her to fuck you like the slut you are.
