Chair sex

When a girl ties you to a chair during sex. She smiled, grabbed me by the wrist, and pulled me into her dorm room. We made out ferociously for several minutes, running our hands through each other’s bodies. Afterwards, we both stripped naked. She had me sit in her desk chair, then tied my wrists to each armrest and my ankles to each chair leg with silk ribbons. She straddled me, mounted me, wrapped her arms around my neck, and we both gasped as she lowered herself onto my cock. With her breasts jiggling in front of my face, she bounced up and down as she rode me, smiling at me as she did so. My wrists and ankles involuntarily twitched in pleasure against my restraints.
