Touching one's sister with lust

Q: If a brother touches his real sister with lust does it invalidate their parents' nikkah?

A: No, however he should sincerely repent to Allah Ta'ala for committing this grave sin and make a firm resolve that he will never ever repeat this sin.

And Allah Ta'ala (الله تعالى) knows best.
