Benny and Sally, meanwhile, were nearly fifteen by now. Their bodies were still a good ways into their changes, but neither of them had fully fallen prey to the influence of their environment. Instead they merely looked around, their aging mind having no better a time explaining what was going on than their childish ones.
Sonja walked over, a smile on her face. "Hey there," she said, waving one red clad hand. "So why you just standing there? It's a party, have a little fun."
"Fun?" Benny asked dumbly. He now looked more female than male now, his features predominantly Hispanic and his chest now sporting B cup breasts.
"Yeah. Just look at those guys," she said, pointing towards the green trio. "They're having lots of fun."
"I'm not sure that's such a good idea..." Benny said hesitantly.
Sonja rolled her eyes, the took Sally's newly enlarged hand and placing it against one of Benny's new breasts. "Here. Squeeze."
Sally complied, and Benny gave a coo of pleasure. Encouraged, Sonja took one of Benny's hand and moved it to Sally's crotch, where a bulge was beginning to grow beneath her suit. This time Benny didn't need any instruction, rubbing against what would eventually become Sally's penis sensuously.
The yellow pair were getting into it now, their changes accelerating as they began to grow more and more bold on their own. Her work done, Sonja stepped back to watch, satisfied that she had set the two on the right track.
