My niece would call me... "There is a swinger party at xxx hotel on xxx weekend.. I'd like to go..." That is all it took.. She was always so hungry, only could share that hunger with me. I'd bring the photo rig and we would set off.., getting hornier by the mile.. Once we got settled in ( I would set up the camera rig and the tv so the porn we liked to watch was fed into the tv...)
Once she was out of the shower and ready to mingle, she would put on one of my shirts.. nothing underneath... then we would go down to the party... I always hung back a bit and watched her work the crowd.. She would work the room, then strike up a conversation with me.. She loved to fuck while others watched, our room usually had the after party.. She loved to fuck while they watched/watch her getting fucked..
