Jack and Me... and His Lodger

Warning: Contains some scenes with explicit sex.
Sarah is broke, and makes a crazy decision to supplement her income by offering her body to a stranger one evening. She is rescued by a former co-worker, who provides her with a route out of her financial problems - and, at the same time, becomes her lover. Things get out-of-hand when she meets his larger-than-life house-guest, who wants a menage with her and her hero. How can she get rid of this cuckoo in the love-nest she wants to build?
