step-Son, me and your step-dad hav been trying to get pregnant for a long time. It doesn't seem to be working. don't you want a sibling? I want to ask you to fill me with your fertile sperm so I can get pregnant. Please step-son! I know it's a lot to ask, but I wouldn't if there was any other way! It might be wrong but I want it so bad! Please step-son fill me with your sperm and make me pregnant!
