Sister and I have a past

My sister and I practiced on each other eating pussy many times. She used to make me just lay there and keep my legs straight with my arms straight above me head. She would lick different parts and watch my body react. One time in a pool she rubbed my clit and pushed me by the jet. Told me to put my pussy towards it and taught me how to get off hands free. She recently came to visit my new apartment and she asked me if I have met anyone in the city yet. Which I haven’t between work and school. She proceeded to get on her knees and eat me out in my kitchen. I feel it’s innocent since we are both consenting and now adults. Idk I like it though. Always feels good.
