I (22F) live with my sister (20F) in a very small half-apartment. We only have a kitchen, bathroom and a bedroom we share. One of us sleeps on the one person bed we got and the other on an inflatable matress on the floor and we each take turns. Every night after i make sure she is asleep i take my clothes off and start having fun near her. Mostly i watch stuff on my phone on mute but sometimes when its her turn to sleep on the bed she ends up with a bit of her foot hanging outside. When she does that i kneel with my face near her foot and just pleasure myself smelling it. I never had the courage to touch it or kiss it im too afraid she will wake up and see me. Is this normal? What should i do? Should i talk to her about this?
