Manual dexterity

Marissa grabbed the vibrator off the floor, and slid it up her friend's leg. She pushed the vibrator into Jessica and watched as she writhed on the bed. She slid the shaft in and out, fucking her friend as she moaned with pleasure. After Jessica has passed out on the bed, Marissa gave herself a few more orgasms and joined he on the bed. After a while Marissa realized she was late for class. She kissed Jessica, promised to see her later and rushed back to her room.
