Jenny stood there in the living room, holding the bottle and looking at Genie, when her sister Sarah walked in the door.
"Who's this?" Sarah asked. "Where did she get surgery for those kind of boobs" she laughed.
Sarah was Jenny's older sister and she had a well developed body, but she normally teases Jenny about her body and that of her friends.
Sarah then walks up to Genie and starts to examine her by walking around her, at the same time poking her with her finger.
Sarah's finger kept moving across Genie's skin till it met with her right nipple, there she pinched it and looked at Genie.
Genie looked at Jenny in a confused sorter way, till her face turned to a horny looking smile.
'Oh this can't be good' Jenny thought looked at Genie and her sister.
Sarah was pinching Genie's nipple for about half a minute before slowing pulling it away, which pulled Genie's nipple out a bit as well making it erect.
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.
