Your dick can't satisfy your wife, it's just too small! Your wife doesn't want your daughter to go through the same struggle, so she decided to get a big dicked guy to fuck them both in front of you. Your daughter must learn how orgasms feel, and your wife needed to have one after all those years married to your tiny cock... Finally, why not removing the condom so your daughter can get creampied right in front of you? Your wife loves to taste the cum mixed with your daughter's pussy juices. Having a big dick in the family is definitely going to make them happy.
