Robert's muscles ripples, as he began to grow in height. His chest and abs became defined, then bulked up further. His whole body stretched as it darkened to an ebony black. Robert groans in pleasure, quickly becoming a hiss, as his face restructures, becoming a mix of a Predator and Xenomorph. His skull elongates backwards. His heart began racing, pumping his now acidic blood through his veins, causing his cock to pulse and throb as it hardened and lengthened.
Mary stood back and watched, grinning broadly as her husband finished his changes, before using her sharp claws to free him from the resin. Robert staggered a little, then stood, his head coming to Mary's shoulder. “Excellent Robert...your change is complete, but now you have a duty to fulfill to your QUEEN” Mary hissed, placing her hands on her lower stomach.
Robert didn't need to be invited twice. He reached his powerful arms out, and gripped Mary's wide hips, and forced her to turn around. “A Queen without a hive is hardly a Queen!” He hissed in response. Holding her hips with one hand, he pushes on Mary's upper back with the other, bending her over the bed, before moving the tip of his cock to her slit. “A problem we'll rectify soon, my love.”
Robert gripped Mary's hips tightly and thrust with all his might into Mary, his slightly-pointed cock spreading her lips easily and delving deep into her in one smooth thrust. Mary screeched with pleasure, feeling his girth press into her. Robert hesitated a moment, letting her vaginal fluids coat his cock, then he began to pull back, before thrusting in again forcefully.
Mary dug her claws into the bedding, shredding it, but hissing with pleasure. Soon to his thrusting she felt her orgasm coming and from his pulsing cock she knew his wasn't far off. “Spill it all inside me!” She commanded him.
Robert gave one final thrust, the tip of his cock pressing against Mary's cervix, before he released like a firehose into Mary, directly into her womb. He held there, as his cock continued to spew forth, and Mary looked down to see her belly expanding slowly as he filled her. As it tapered off, Robert pulled out slowly, panting heavily. He leans forward and nuzzles Mary gently. “How long do you think?”
“Soon” Mary replied with a wide grin. “Very soon”
