Lesbian Blog Reader Needs Your Help !!!

Compliments on the good job you are doing. your blog is indeed a blessing to me. I am a blog reader though i rarely comment. I need your opinion on this issue please.

My husband works with an oil servicing company at Brass and he is rarely at home. He only comes home once in 3 months to spend a couple of days with us. Honestly its not been easy but some how God has always led me on.

My sister in-law (hubby's younger sis) has been in my house for some months now and we are best of friends. i don't know how it happened but before i could think, I saw my self in a sexual relationship with her. she actually suggested it when i was lamenting on my state of loneliness. I accepted because i have always been bisexual from way back in school.

I gave in and it has been rewarding but somewhere deep inside me i feel bad. my sister in law is almost 5 years younger than me and she still calls me aunty. Even though it was her idea, I feel as if i am spoiling the young girl and then being my hubby's sister makes it even more weird.  

Even though i feel its better to have sex with her than to cheat on my husband with another man, I still feel uneasy after engaging her.

please what do i do?
