At twenty-three I enjoyed a very full sexual life style so when he offered me what I needed in exchange for what he needed, I accepted. At first it wa... fun he would ‘force’ me to do my homework and get good grades. Then he had me fuck some of my professors for better grades and that was fun too.After we graduated we got jobs at the same school and I continued to be his sex slave. After all it was fun and I enjoyed fucking his friends and acquaintances.Then last school year he told me to fuck.

It has been a long time. “Not quite fully aroused yet Sarah,” he teases as he sits on a chair and motions for Sarah to kneel between his legs as he strokes his cock with a fingertip. Then he motions for me to stand close to him and slides a hand along my erection.“Your cock is bigger than my two buddies you watched last night. And thicker. And I am fully aroused now Sarah, for both of you. Just over eleven-inches for both of you Sarah,” he whispers just before Sarah watches him commence sucking my raging erection.Then.
