You're being disingenuous. We've been through this before, and it was well established that playing doctor is what two kids do willingly.
A 14 year old going to his sisters' beds and forcibly molesting them is not playing doctor. The same is true for said 14 year old feeling up his 5 year old sister under her dress.
Look up “Dysphemism”. Interesting that your explanation does not match the family. I’d like to see the sisters deal with you face to face. They’re getting pretty good at slapping down ignorance.
