In the quiet of the library, a student's gaze lingers on his professor's ample cleavage, her big tits heaving with each breath. The young man's cock stirs in his pants, growing harder by the second. Unbeknownst to him, the professor notices his arousal, her own panties dampening. She teasingly adjusts her blouse, revealing more of her heaving bosom. The student, unable to resist, excuses himself to the restroom, his massive cock tenting his pants. In the privacy of the stall, he releases his throbbing member, stroking it to the image of his professor's big boobs.
