Lulu Chu's sperm clinic is top rated and she has a waiting room full of guys eager to have her swollen balls emptied. She guides her enthusiastic patients to various rooms, sucking and caressing them and directing their semen into appropriately designated containers. The work of going in and out of those rooms is tiring, so Lulu decides to take on Mazee the Goat and Alex Jones twice at once - work smart and work hard! Lulu uses her expertise to get the sperm samples they crave, using her mouth and pussy to work their cocks in equal measure. The work is challenging but rewarding, and Lulu's semen-filled sample cups are proof!
