Looking at Ty, Buck spoke up.
"Is that it? Or are doing even more?"
"Oh, we're doing more alright," Ty said, smirking.
"Oh no..." Buck murmured, getting slightly antsy.
Silently, Ty willed the changes to take place, first in Buck, then in himself.
Buck shuddered as he felt pleasure rush through his crotch once again, this time settling around his lower abdomen and the stretch of skin between his balls and his taint. His innards shifted and gurgled, conforming to new, unnatural positions. Gasping, he felt the skin part, revealing a new, puffy, pink slit, pulsing with arousal.
Grinning, Ty moved behind Buck and fingered the new addition, making the young stag shudder. Smirking even wider, Ty dipped a two fingers in for a tantalizing few second, before pulling them out licking them off, leaving Buck gasping for breath.
