Elise immediately did what was asked of her. Her long, slender legs moved further apart and she reached back, placing one hand firmly on each buttock and spread them wide open. Lily stared down at the woman's ass hole, pulled taut. She remembered that daddy sometimes rubbed her asshole as he was fucking her pussy, and once he had even slipped his finger a little inside her but she hadn't liked it very much and daddy, being in a good mood that time, had not tried anything else but had kept his finger slightly in her ass as he came in her pussy.
The headmaster looked at Lily and stood back slightly. "Elise's ass hole needs some lubrication Lily."
"What?" Lily was suddenly extremely unsure of what was expected of her.
"Spit on her ass hole," daddy instructed her, gently pushing her forwards towards Elise. Lily looked at her daddy in shock. "Do it baby." He encouraged.
Lily leaned over Elise's spread ass, she gathered some saliva in her mouth and let it dribble from between her lips right down on to the tiny ass hole on display to them all. The headmaster smiled as he stepped forwards again. He put the tip of his middle finger into the frothy patch of spit and began rubbing it around Elise's ass. Lily watched as Elise's ass hole contracted and loosened depending on where the headmaster's fingers were, but the girl made no noise.
"Now you try," the headmaster instructed Lily, "rub your little fingers around her ass hole for us."
Lily started to feel a little sick. Surely this was not right, playing with someone's ass hole? But as she lowered her middle finger down and started rubbing Elise, she began to feel the tingles starting in her pussy. She knew the woman must feel humiliated but that was what made it so much sexier. She didn't see her daddy and the headmaster smile in approval as she dipped her finger slightly inside Elise's ass, but she did hear Elise moan with a certain degree of pleasure. The small opening closed around the end of Lily's finger, pulling it slightly further in and Lily pushed a little harder. The spit assisted in lubricating the hole enough for Lily to slide her finger in down to her first knuckle. Elise had begun to moan a little louder. Slowly Lily drew her finger out and pressed it back in further, this time managing to get it in to the second knuckle. There was something nice about the way Elise's ass gripped her finger, flexing and contracting, almost like a tight pussy. Again Lily withdrew her finger and, without any prompting spat again, on the ass hole in front of her. With this extra lubrication Lily slid her finger all the way in to Elise's ass hole.
"Oh fuck, Lily," the girl moaned, "that's so good."
"Good girl," daddy said, coming up behind Lily and reaching both hands around to her breasts. He fondled them and squeezed them, tweaking her nipples every down and then as he watched his daughter's finger start to fuck Elise's ass hole. "Daddy likes watching you do that." Daddy saying this made Lily's pussy wet again, she felt daddy abandon one of her breasts and his hand slid down her stomach and between her legs, where he spread the juice over her pussy as his fingers rubbed and delved in to her. The harder and faster daddy rubbed her cunt, the harder and faster she fucked her finger in and out of Elise's ass hole. As Lily started to feel herself cum she was moaning loudly. Daddy was pushing her down to her knees, he knelt behind her, still fingering her cunt as she started to come.
