The story was originally posted on iss website back in 2008.I had contacted the original author online and according to him the story was based on his real experience.
The affair doesn't lasted long after he posted the story as he got shifted to another city followed by his friends too.
Later Gayatri also shifted from there. By that time she was pregnant though no one was sure who was the real father of the baby inside her as she was fucked by Kartik , his 3 friends and their manager too later for months apart from her husband without protection and didn't bother to take pills regularly.
Her husband also later doubted about the affair though he wasn't man enough to confront them so he chose to shift.
Later Kartik and friends lost contact with her and are not sure whether she kept the baby or aborted it.
It is one of my favourite group sex stories till date despite being very old.
