On her knees looking up at Derek after he completed the undressing himself Kristina pouted, her lust again being denied. The thing about lust being that it is relative to each person, Kristina it seemed was the type to lust after climax and self-gratification because she had been so close to the edge of cumming the moment that she put her hand down her mom jeans in the elevator. Kristina it seemed was the type that enjoyed pleasing others, or at least her mind was rationalising her obeying Derek's commands as such.<br/><br/>The petite college student crawled back to the sofa on her hands and knees then got up on it like instructed. She pressed he back to the rear of the chair, put her feet in the edge, legs opened like the letter M and resumed rubbing herself. This time it was just two fingers in little circles over her clit as she bit her lip and looked away. Soft moans began to come from her lips then her free hand cupped her breast. Kristina bit her lip harder and teased her nipple as her fingers increased in speed.<br/><br/>Shortly after she searched for orgasm rather than just masturbate her hips shot up into the fingers at her pussy.  Kristina squeezed her eyes closed as her hips spasmed into her hand as she came there masturbating in front of her school friend.
