Sally & Emily's Bedtime #3 (Commission) (Pixiv Fanbox)

Sally was deep into the pleasure zone by now.   Her back was arched and now fingers from both hands were deep inside her anus and pussy.  She closed her eyes and moaned, as the FanBox pics had done their purpose.  The visuals of Bethany and Alice having passionate sex were replaced in her mind by visions of her and Emily in the throes of lustful, wanton intercourse.  

But what she didn't know...was the Emily had by now entered the room, standing over her little sister.  Her eyes skipped between her sister's frantic fingers and the sight of Alice and Bethany's incestuous coupling on the laptop.  Emily's fingers reached between her thighs and urgently masturbated her clit, her body soon covered with a fine sheen of sweat.
