The bitch had to be crazy! ofcourse her offer to become a surrogate was too rosy to be true. Unfortunately because she was too desperate of having a baby of her own, she didn't really think things through when Megan offered herself to carry her child.
In the past life, the two sisters had an earnest conversation about the dos and don'ts the older sister had to endure to prepare her body before and during the pregnancy. The biological mother was aware of the wayward life Megan had chosen to live and that needed to change that until after the baby was born.
During that conversation, Megan had promised to give up all the bad habits she enjoyed like drinking, smoking and fucking random dicks just for the fun of it atleast until she gave birth and because she was too desperate at the time Luna took her word for it.
