Venus Lux, Sarah Vandella's trans sister, is a walking temptation in lingerie. Her massive, rock-hard shemale cock strains against her panties, begging for release. Sarah, caught in the act of watching, can't help but stare. Venus, sensing her sister's gaze, turns and winks, "Like what you see, sis?" Sarah blushes, "I... I didn't know..." Venus chuckles, "Now you do." She walks over, her big ass swaying, and presents her massive dick to Sarah. Sarah tentatively reaches out, her hand wrapping around Venus's thick shaft. Venus groans, "That's it, Sarah. Stroke your sister's big cock." Sarah complies, her small hand struggling to fit around Venus's massive shemale dick. Venus's massive dick throbs in Sarah's hand, leaking copious amounts of pre-cum. Sarah, her cheeks flushed, looks up at Venus, "What should I do with all this cum, sis?" Venus grins, "You'll see."
