Wife Shared With Cousin

During covid times me and my wife used to get drunk a lot and get super horny. One night we was having some drunk fun and my cousin messaged me and as a joke I messaged him back saying I’m busy and sent a pic of her sucking me. He replied saying “where’s my invite….. just kidding” so I told her what he said and she said it was up to me. So I invited him. He turned up at the house and walked up the stairs like I told him to and sat on the bed very shy. To relax him she took him downstairs to get him a drink while she had no clothes on. 10 minutes later I walked downstairs and she was on her knees sucking his dick and I just stood and watched while jerking off then I got behind her and fucked her from behind until we both came. Then he got up and left and we’ve talked about doing it again ever since.
