During late-night overtime, an office worker discovers that the cute junior colleague assumed to be a woman is secretly stroking a large erection. Seeing the femboy unable to focus, the senior lends a hand and helps bring on repeated penile orgasms. The sight becomes too arousing to resist, leading to anal penetration and direct prostate stimulation with a cock until the junior has ejaculated 14 times and finally burns off all that pent-up desire.
