After a man learns that his only child is a lesbian he is worried that his line will die out. He is really happy for his daughter and is proud that his daughter found someone that can make her happy. Despite that he asks his soon to be daughter-in-law to use his seed to get pregnant. He asks her to use a special dildo that if you press a button it will release his seed. The daughter-in-law agrees only if her own father agrees to the same thing. When it comes time to inject the seed the daughter-in-law switches the samples so they can both get impregnated by their own fathers. Her soon to be wife doesn't find out until later. But she doesn't get mad or at least doesn't stay mad for long after she does find out.
