I share a bedroom with a older sister . This morning she woke me up . Sounding like a slight moan . I asked her if she was ok ? She replied yeah feeling great . Then I asked what are you doing ? She looked over and smiled and said really . She giggled and said she was m***********. I gave for a blank look ? She got and sat next to me in my bed . She pulled my bed sheet down . And said pull your nitties down . I thought she was crazy . Again oh come on gotta learn sometime . She took my hand and showed me wear she was rubbing . few minutes later oh my god it really felt great . She returned to her bed laid on top of the bed sheet . Knees up in the air . I watched her finger her p**** . She looked over and said go for it , It’s great .
