During work hours, a busty female senior tries out intercrural sex as a rehearsal to help her virgin junior gain confidence! Although she is conflicted and embarrassed, she teaches him how to kiss and intercrural sex, and the junior's dick becomes fully erect and is on the verge of exploding! When the clit rubs against the erect dick during intercrural sex, the female senior lets out a sigh! If she is found out, she will be fired for disciplinary reasons, so she monitors the virgin sex completely!
