My girlfriend and I took a trip out to Las Vegas for a friend's wedding. We arrived pretty late (around midnight) so after checking into the hotel, my friends came over and wanted to take out the groom for one more night of debauchery before his wedding day. My girlfriend smiled at me and told me she's going to call it a night and to have fun. A few hours later, multiple lap dances and bottles of liquor, I stumble back into the room around 6am and slide into bed. Not an hour later, she wakes me up while giving me head (as needed because I had blue balls like you wouldn't believe). She stops and smiles at me before asking me to open the curtains so I could fuck her in front of the glass. She gets off knowing someone might be watching so obviously, as tired as I am, I oblige because I figure this could be one of those rare moments she lets me do whatever I want. I put a chair in front of the balcony window and we start hitting every known position. She knows I'm about to cum and surprises me by getting on her knees and telling me to cover her. It took me a little longer because I was so surprised since this RARELY ever happens but oh my god THANK the lords for her inner voyeurism.
