Derek and his pal Ken

It didn't take long before she felt something on the back of her neck. June could feel the sensation of something hard rubbing against her hair. She turned grinning as she saw the massive shaft in front of her. It was her first but I definitely would be her last.

There was no doubt in June's mind that she was going to enjoy herself as the shaft continued to swell and change. Becoming less human and more equine. June had a kinky mind. So it only suited her to place her hand on Derek's manhood gently grinning as another boy, Ken she remembered, approached on the other side Melanie found herself trying to ignore a bulge. It wasn't going to work June grinned as Derek lost patience grabbing her head and forcing her to take his huge horse cock into her mouth while her sister discovered exactly how aggressive a boy could be when they were horny. The sisters were quickly dragged from their chairs Melanie had started to scream but she found her mouth full of a scarlet knot June quickly got on all fours wiggling her rear as she tried not to **** on the debate boy's thick meat. It was quite amazing to be so utterly helpless. She grinned turning her head just enough to watch Ken's transformation eagerly.

She wasn't in control of his transformations at all, although she could doubtless snap fingers if things got too intense. She was surprised to see that Melanie was now suckling on a large muscular canine cock while Ken's new second phallus slapped against her cheek. He wasn't just changing down bottom but top as well, June watched in amazement her own mouth full of foul tasting horse cock as Ken's head began to twitch and judder splitting in two as the boy came down on top of Melanie's head. Large clumsy paws grabbed her sister's blonde mane thrusting deeper down her throat. Ken was still changing but June was quickly being eclipsed she felt something grip against her rear as her panties were torn from her. Still sucking hard she could only feel her eyes roll back as someone else thrust themselves up to meet her hips. She was being spit roasted something cold and smooth sliding against her hips. She wondered what she had unlocked.

The sheer shameful display already making her shudder she pulled back still jerking off Derek and felt her breath fall away from her as she beheld what had become of Miss Flores
