The Joy of Watching **

Tina arched her back. A weird sensation originated in her lower abdomen and coursed through her entire body. It became hard to breath. She clenched her skirt, making sure it doesn't fall down and interrupt the lady.

Irene had practiced fingering on Cassidy many times before. Adrian taught her a plethora of ways to play with pussies. Though she had never used such techniques on herself before as she did not feel any sort of cravings, she took her tutor's orders seriously.

She tightened the grip on Tina's shoulder on the other side. Her own breasts were massaging the shoulders on this side. Irene was slowing increasing the pace of her strokes. Her mouth was still close to Tina's ear.

"Do you like it?" She whispered. Her charming cold voice and warm breath caused the young girl's ear to twitch.

"Mmh… Ye… yes." Tina barely uttered. 

Her entire body was hot. The scene in front of her only added to the feeling.
