Ty started up the stairs, but the cries and screeches of his former step parents fucking each other silly in their new velociraptor forms drew his attention back and he couldn't resist. Besides, Dustin wasn't going anywhere.
Ty turned back to the display just in time to see the larger June throw her head back and suddenly pull her leg up into the air, curling her sharp feet claws as she orgasmed from the insatiable fucking of her smaller lover. It was hard, passionate, wet and drippy, wild and unrestrained sex. The two former humans were completely lost in their world of pure pleasure. Mark was panting desperately, having cum so many times from his twin cocks that they were swollen and sore. He was still humping eagerly, but it was clear he was growing exhausted.
Ty started in aroused fascination as June milked her dinosaurian husband for everything he had left. He saw her hot and wet dinosaur vent twitch and spasm wildly. She was far from exhausted, screeching again and again, falling onto her arms, grinding back on her lover and focused only on pleasure.
Mark let out a gutteral cry suddenly and flopped forward, his little chest heaving and his arms falling limp. His eyes half lidded as he came one final time, slipping free from June's vent and literally collapsing on top of her.
Enraged, June screeched and snapped at Mark, who lazily slid off of her and flopped to his side, falling still and dozing off into a deep post-orgasmic coma.
This left poor June half-pleasured and frustrated. She screeched again and turned, spying Ty standing by the stairs. She paused, sniffed the air, and he saw the feathers on the back of her neck lift slightly. Her eyes grew curious.
Ty blinked suddenly and realized what was happening. He was sporting fully grown wood and it was tenting his shorts. He gasped as his stepmother approached him carefully, ruffling her tail fan and swaying gently, letting out a trill.
Oh shit.
"June..." Ty whispered. "A-Are you still in there?"
The raptor brightened as she recognized her name but showed no outward human intelligence. For all Ty knew her mind had reduced to fit her dinosaurian body. She was showing very beastly behavior. She was dripping with both cum and her own arousal. Oh man, Ty was so turned on.
"H-Here June..." Ty called softly. "C-Come here, girl. Come here my little dinosaur."
The raptor cocked her head quizzically and chirped. She watched Ty carefully and sniffed again as he sat down on the floor. The dinosaur walked forward carefully and stared at him, snapping her jaws noiselessly. She sniffed once more time and trilled deeply, her tail fan spreading out into a marvel of patterned blues and reds.
"Oh my God." Ty laughed. "We're doing this, aren't we?"
The raptor didn't understand the words but none the less she stepped forward submissively, lowering herself to the ground as she walked and holding her head down. Ty reached for her gently and gasped as the dinosaur let him pet her. Her protofeathers were so smooth, he could feel the warmth of her reptilian hide beneath them. His hand began stroking her head, petting her long neck. The velociraptor let out a pleased trill.
She turned suddenly, displaying her tail, raised it, and pressed her ass up into the air. Ty realized that the dinosaur still smelt of his step mom's sweet perfume. His jaw dropped as he stared into a wet and blinking hole set beneath another hole closer to her tail.
Ty quickly lowered his pants and freed his dick. The raptor saw this, screeched excitedly, and sniffed the air frantically. She turned to face Ty's dick, eyes wide, and experimentally stepped forward to stare at it.
Ty sat there, breathless, as the little lady raptor blinked once or twice, reached her nose forward...
