Till Marriage Do Us Part (1974) is an Italian farce that poses thought-provoking questions about taboos and sex. Sexy siren Laura Antonelli and her lover are newlyweds who learn that they're brother and sister. While they try their best to avoid the obvious attraction, Laura still finds time to get completely naked on more than one occasion. She even thinks that the situation may not be that great of a sin. Whether in bed, bathing, or at the stable, Laura wants to horse around, and she likes to ride bareback. Thankfully they find out at the end they're not related, so Laura's rear end is no longer off limits.
