That’s too bad, I impregnated my sister 23 years ago when I was 19 years old. My brother in law thinks that is his to this day. It’s a wonderful feeling.
She still has sex with him regularly but has no intention of getting fertilized with family seed. It's a foolish risk to become pregnant by ince*st even if a woman wants to. She loves his cum in her pussy but doesn't want a taboo baby.
Every time that my wife had unprotected sex with her brother when they were teens, he discharged deep in her pussy so they both would enjoy the intercourse and consummate a sexual bond that still exists today. She says that he always finished their love session with a comment about a possible pregnancy if she didn't watch her calendar for her fertile cycle. She is still amazed by the fact that she didn't get preegnant by him because she enjoyed his semen in her vagina countless times and carried his seed for hours after he withdrew.
