We were so poor when we were kids, dad used to jerk off the dog to feed the cat.
“This isn’t the first time my husband’s cheated on me, but you’re my sister! You’d better have a better explanation than this magic lamp.”
“You know how you have to be specific making wishes? Well, I was really horny and asked the genie to have the world’s biggest penis…ended up with a concert pianist that’s seven foot tall. Nice guy. Next time I tried, I asked for the world’s biggest cock, that was fun but the poor rooster died. So I asked for the world’s biggest dick and that’s how I ended up on top of your husband.”
