Liara, her futa cock straining against her uniform, finds herself alone with Eva in the dimly lit lab. Eva, unable to resist Liara's allure, approaches, her eyes locked onto the bulge in Liara's pants. She unzips Liara, revealing her massive, veined cock. Eva eagerly takes it into her mouth, sucking and stroking until Liara's hips buck with pleasure. Liara, overcome with desire, pins Eva against the table, her big dick pressing against Eva's wet pussy. She grinds against Eva, making her moan and beg for more. Liara obliges, missionary-fucking Eva hard and fast, her big cock stretching Eva's tight cunt. Eva claws at Liara's back, urging her on. Liara pounds her mercilessly, filling her with a torrent of hot, thick cum, leaving Eva panting and satisfied.
