Viki Tai is a Thai adult performer and model from Bangkok who entered the industry later in life as a mature MILF and hotwife. Born around 1984, she began posting glamour, lingerie, and adult content online from roughly 2023 (previously associated with the name/handle Siweetpie) while describing herself as an accountant, model, and artist, before making her professional European debut in May 2026 with the VIP4K/Debt4K webscene Marriage Story, a reality-style hardcore involving a debt collector. She has since appeared in titles such as the Cuckoldest scene My Wife Is Horny One, featuring interracial cuckold action with oral, vaginal, and fisting elements. Known for her short brown hair, shaved appearance, and natural curves (self-described as an Asian MILF with 38D breasts), she has shot in Prague and other European locations under SM Management and maintains an active presence on OnlyFans, Instagram, and X; her height and weight remain unlisted and unknown.
