"ass or pussy?I ask Liam as she is too far gone to say. He looks her over and bites his lip. "I would like to try her ass", he mumbles, fisting his cock and groaning as she touches his abs and moans herself over his body. Took us awhile but we fattened him maybe not fat but he put weight and muscle back on and Anna loves it. She touches our abs, loving running her fingers over them and saying we are cut perfectly. Most times our cocks stay hard because she is always touching us and moaning about how hard we are. " good cause I want that pussy bad", I say playing with her clit getting a little gasp.

Murry tried to run again, but he only made it halfway down the aisle. Large hairy hands with stabbing nails grabbed around his ankles. The claw nails shredded his jeans. Murry fought and kicked, but soon other hands came at him from all sides. His shirt, what was left of it, tore from his body. Twisting, he tried to get out of the hold. The creatures didn't seem to be phased by his movements. Murry knew he didn't have the power behind his strikes to make a difference. He didn't eat enough to bulk up, and he had never exercised or cared about his health. Murry simply lived every day the same. Now he wished he'd done some damn pushups or sit-ups in his life. His muscles became fatigued the mor

His body might have endured months, even years of training here, but in the real world, only seconds had ticked by. "I guess I don’t have to worry," Danial muttered, calming himself. He looked down at his sword, its blade shimmering in the faint starlight. "Let’s finish this." Time blurred once more as Danial threw himself into the final stages of his training. His swings became sharper, more precise. Months passed again in the realm, and Danial noticed his body growing stronger and more defined. His muscles had become leaner, his shoulders broader, and his face had changed, showing the signs of a man who had weathered battle after battle.

she said. “What would you like to do, beautiful?” I asked her. I’m more than ready to take our relationship further. As a foster kid and runaway, I’d been having sex for years. I enjoyed it and it was a way to escape the reality of my life for short periods of time. But ever since I got my dragon form, I feel like my dick is permanently rock hard. Now that I’ve found Emmi and we’ve been getting closer physically, my dick feels like it’s going to explode most of the time. Even when I’m in the shower, I have to ease the ache multiple times just so I can sleep at night. Then, my dreams are filled with Emmi and Phoenix and I’ve started waking up in the middle of an orgasm, sometimes multiple tim

That if Bridget or any of them wanted me, I should shut up and get over it. Well I didn’t want it that first night or any other. And I haven’t… gotten over it. My body relaxes as my biceps grow, my height increases and my skin quite literally moves in grotesque ways. Bones shift and move to accommodate my now eight foot frame, until I can no longer see directly into the mirror. I swipe my hand at nothing but air and bask in the glory of the talons on my fingertips. My tongue runs over my long teeth, and I allow a point to prick it, drawing blood.

I hiss in a sharp breath when Celine reaches out to touch it and it feels… So fucking good. Pleasure shoots through me like she just touched my clit and the organ jerks and protrudes even more, filling with blood. All three of us gasp as we watch the definitely-not-a-penis grow. It grows and grows and grows until it’s standing like a flagpole, just as long, thick as a baseball bat and hard as a fucking rock.

She bit back her sobs of relief and release, as the longest, strongest orgasm of her life crashed over her, through her. Her back arched impossibly from the force of it, and Scars growled as his cock went deeper than ever before. Her muscles were clutching his cock, clenching and then releasing like hands, and he gritted his teeth to hold on until she finished.

“Your tits getting bigger. Your belly growing. Everyone thinking it’s some college boy’s… but we’ll both know it’s mine. My secret baby growing inside my daughter’s best friend.” The filthy fantasy pushed Lila over the edge again. She came with a broken moan, shaking in his arms. Marcus followed right after, pumping another thick load into her already overflowing pussy. Still not satisfied, he rolled her onto her back once more and pushed her knees up to her chest, folding her in half. The position let him sink even deeper. “Look at me while I breed you,” he ordered. Their eyes locked as he fucked her with slow, devastating strokes. Sweat glistened on both their bodies. Lila’s voice was hoar

As Jade thrusts back into me, I bite my lip and hold Dan's shoulders, staring into his lust-filled gaze. I groan. After that, it's Dan's turn. There is no time to stop and consider. My muscles are refusing to work as Dan and Jade settle into a rhythm, thrusting deep one after the other. As he presses harder, Jade's grunts turn into growls, his pelvis smacking into my ass. As I take them both into me, Dan thrusts up into my body, my muscles straining, strained beyond what I imagined they could ever be. It was so near.

It's as if I'm being pulled apart and stitched back together again, my bones shifting and reshaping beneath my skin. “What's happening to her?” Ethan asks, his voice laced with fear. Suddenly, I feel a surge of power coursing through me, and I let out a guttural roar that echoes through the room. I wonder if anyone else can hear my bones cracking and breaking, and I try to lie still to make it go away, but it doesn’t go, and I can’t stop trashing. My body elongates and expands, fur sprouting from every inch of my skin as my limbs grow longer and stronger.
