My mum and I have always had a very close relationship. We cuddled together very often and kissing was also quite normal. We sometimes shared a bed due to our living conditions. Doors were never locked and being in the bathroom together was basic. We always flirted a little for fun. Before I turned 18, she asked me what I wanted and I jokingly said a striptease. When my birthday came around, she did it. She had cooked for me and we had a drink. She went into the bathroom and I went into the living room. When she came back, she was standing in front of me in her bathrobe and dropped her coat in one fell swoop. She stood in front of me in purple lingerie, she danced for me, she even twerked for me. I really enjoyed the sight. She also pressed my face into her arse
