As soon as Sarah's fingers left contact with Genie's right nipple from sliding off, she disappeared!
Sarah's clothes then fell to the floor where she stood.
Sarah then found herself on the very nipple she pinched.
"What the?!" but Sarah then felt a sudden rush of arousal in her body from her lower regieons to her very own nipples!
"oohmm" "ahh"
Sarah started to fondle herself as well as rubbing her legs up and down; which were securing her to Genie's giantess nipple!
"What have you done with my sister!" Jenny said running over with the bottle.
Genie's eyes shifted to her right nipple and Jenny looked, she could see something on it but it was hard to make out from where she was.
She then walked closer to look and she saw her sister there on Genie's nipple, fondling herself as well looking completly aroused at the sametime.
Sarah saw her giantess sister standing quite close to her admiring her aroused, developed body as she was fondling herself.
She could help but enjoy it, she was starting to think if she had become a lesbian.
Jenny then looked up at Genie who smirked.
