Chapter 90

• Chills were running up and down Sam's spine as she worked on Sally's ass. A shiver of pleasure ran through her at the thought of the conservative professor of English sucking a woman's asshole. What would my friends say if they saw me right now? she thought. But then all thoughts left her mind as she pulled away and looked at the spread ass of the trembling girl. Then, she took a trembling finger into her mouth and made it wet with her saliva. She then placed the tip on the little rose. With gradual pressure, she pushed forward.
• "Oh God, oh God, oh God," Sally gasped, as she felt Sam's finger slipping into her.
• Sam watched as Sally's hole took her finger inside. It felt like the hole was resisting and pulling at the same time. She continued to press forward until it could go no further. Then she pulled it back out, watching the tight hole resist again. She forced it back in again. She couldn't believe how warm and tight her anal walls felt on her finger. Slowly she began to move her finger in and out until she had established a steady rhythm.
