I vote Lia and call the fight the following way:
Let's get ready to rumble...
Lots of give and take between both women. but Lia eventually wears Jane out. Jane grows arm weary and eventually she can throw no more punches or hold her arms up to defend herself. Lia takes advantage of this and soon Jane is pretty much out on her feet. Lia continues with punches to sexy Jane's belly til she is nearly passed then sends Jane to the sand with and uppercut. Lia straddles Jane pinning Jane's arms to her side. Lia looks up smiles and asks one of the onlookers to count Jane out which they do. As Jane regains her senses Lia strips Jane and ties her hands with her bra and panties then proceeds to facesit her while mauling her pussy and boobs then parades her through the bar like a trophy and as she does she tells HER boyfriend to meet them up in Jane's room in 15 minutes. Lia's new boyfriend enters the room to find Jane, sitting naked tied to a chair, that has been moved to the foot of the bed, with Lia's bikini top and bottom, and her hands still tied behind her back with own bikini top. He then looks over a Lia who greets him with a smile as she kneels on the bed twirling Jane's bikini bottoms around her fingers. Lia's boyfriend smiles back and begins to move toward a very proud Lia, peeling of his tank top and trunks along the way. He reaches Lia, raises her arm in the air and says: "To the Victoress go the spoils!" Then he looks deep into Lia's eyes and gives her a long wet kiss as they begin a very long and passionate lovemaking session. Jane can't look away and has to jealously endure Lia's sexual exhibition taking place on her own bed, while she basks in her shame of losing. Jane's final humiliation comes as she is forced to sleep in the giant wet spot of Lia's glorious sexaul revelries with her new lover while Lia and her boyfriend lie next to her sleeping in each other's arms for the rest of the night
