Big sister is so lovely and protective in her way

To put in a context she’s 24 and I’m 20. Very protective since first day she made me hers. I literally fell in love with my big sister. The sex is so powerful. She welcome all of me inside her then I am well and comforted me with her warmth and moans. My sister owns me and I own her . She clearly make me her territory. Her little bro but her man and her dick , no one else
