I've been groping my little sister's breasts since she was young, and as a result... Since she was small, my sister was incredibly cute and weak-willed. I kept touching her breasts, and her reaction changed from 'ticklish' to 'feels good'! When I thought her reactions had changed, she suddenly seemed even cuter, so I assaulted her! On top of that, I forced myself inside her unwilling sister!!! I thought it was too dangerous and regretted it, but then she said she wasn't satisfied and attacked me next... leading to more intense sex!
