After having grabbed their candies, they ate it.
Gabriel's POV: after swallowing the candies, Gabriel felt hot, the very horny kind of hot. He moved to get up when Mary and Jenny pretty much flew to either side of him, his arms being squished in their breasts. He then felt his skin tearing through his shirt to connect to them, once his skin touched theirs he felt them being sucked into him.
He felt his hips widen as he swallowed theirs, his thighs thicken, his cock and balls sucked into his newly formed pussy, his legs lengthen, and his feet turn into claws. Blue scales started to form and run up from his feet, as their torso's merge he felt his once flat chest swell to form a pair of large E-cup breasts. Mary and Jenny's heads where now on either side of his, and as he felt the scales reach up their necks, their necks lengthen and their heads turn Draconic, they then felt a pair of large wings emerge from their shoulder blades and a long tail came out from their behind. They looked at their fertile anthro dragoness body. Jenny and Mary attempted to satisfy their body, but quickly found they could only control their heads.
They then turn their heads towards Mark once they heard him groan as his body changed. Mark quickly fell onto all fours, as his clothes teared, bronze scale began covering his body as his feet and hands turned into claws, and his back lengthen. The Gabriel Dragoness couldn't see the changes happening on his chest and waist, but she could smell it. Mark now had a draconic dick and pussy, as well as having eight (4 pairs) small breasts. It was clear now that Mark had the body of a Feral Futa Dragon.
Gabriel then turned her head to the parents and saw Robert eating out his wife as he began merging with her lower half. Melissa upper half quickly became draconic and she ripped her blouse reveling her C-cup breasts. Her legs became very masculine and dark Green scales
began covering her. The Gabriel Dragoness stared at Melissa's crotch as her husband Robert became her large draconic dick and balls, with his fleshy draconic muzzle being her tip. It was clear now that Melissa was a shemale anthro dragoness.
