Let her seed herself

Overwhelmed by your musk and the milk Susan has fed her, Gwen seems all too willing to cooperate. She moans in disappointment as you lift her up and away from her feeding, but giggles as you lay back on the bed. Your cock still impales her, her body suspended above yours by the thick pole of flesh.

Rubbing her stomach, you make clear what is to come next. "I think you know what to do." Gwen immediately nods and begins trying to **** even more of your cock into her womb, not getting very far. Undeterred, she begins swiveling her hips, causing your cock to stir up her insides with audible squishing and the bulge of your cock distending her skin as it moves about.

"This is...unbelievable...!" Gwen's hushed panting confirms her enthusiasm as she switches back and forth between gyrations and pushing more and more into her. You wonder if the **** in her system is the reason for her willing acceptance or not, but decide it's not important right now. It lasts for many long minutes, her gasping and moaning accompanying the squishing of fluids as she pushes you ever further into her body. "So...so deep. I can feel my organs moving for you...but it doesn't hurt... Oh!" Her orgasmic squeal is cut off by Susan once again, this time with her mouth, as you feel the last few inches of your cock enter your new mate and your knot swell to full. Gwen's eyes fly open at this, her entire body shaking violently as her pussy spasms around you.

Susan waits for her to calm down before letting her speak. Gwen places her hands on her stomach, feeling the bulge of your knot in awe for a long while before tracing up her stomach to the tip of your cock. Now, you're no expert in human biology, but you're pretty sure the human womb doesn't extend into the ribcage. The magic you had unleashed seemed again to be the only explanation, and you're really wondering if it's growing stronger with every passing moment. You'd never have been able to do this with Amy when it first started.

"My God... I must be dreaming..." Gwen mutters, as dumbfounded as you. "It may be a dream, but we wouldn't want to wake up by screaming too loud, would we?" Susan's remark brought a bigger grin to your face, using the girl's inebriation to continue not alerting the pair downstairs of the events taking place. She just nods and bites her lip, slowly beginning to lift herself up and down around your massive knot.

She can't move very far, but she thrusts you back and forth about 3 inches or so by lifting up and letting gravity pull her back down. You grab Susan and set her atop you, her pussy right above your muzzle, and she catches herself mid yelp as you begin rewarding her for her efforts. Her pussy has a new flavor, that of a pregnant woman, and you find it intoxicating. That she is pregnant with at least 8 of your young drives you higher, your orgasm reaching its peak alongside both women after only a few minutes.

You hear a muffled grunt of pain from Gwen as bliss washes over you all, but you can't see her behind Susan. You know at least partially what it happening to her as you pump gallons of thick seed into her hungry womb, your clawed hand reaching around to feel as her belly balloons outward with each gush. Her smell changes as her body releases several eggs, and you know yet more life will be growing in her after you change her.

When Susan slumps to the side, however, you see what the cause of the pain was. Even as her belly grows larger still with your seed, you both stare at the teeth marks on her shoulder from where Susan had bitten Gwen in her lust. Small amounts of blood trickle down her skin, and the transformation begins with the familiar painful cramp.
