After graduating, Lulu visits her professor to express her enjoyment and crush on him, leading him to engage in sexual activity over his desk.
Kyle is aware that Lulu Chu owes him a favor after he helped her out the previous year, and she is returning to town for the summer. Thus, Kyle persuades Lulu to visit him and extends an invitation to her. They might declare the favor reciprocated if she accepts his cock in her lovely pussy. Lulu looks at Kyle's massive boner and decides it sounds like a fair bargain. She then gets to work extracting every last drop of warm jizz from that booming cock.
