It was late and the night out was winding down. Drunk and high me and my girlfriend made our way back to her house along with 3 of her friends. We all did a couple of shots and settled in the living room. It didn't take long for the topic of my liking for lingerie to be brought up. 'So then, we have been told that you are a cheeky man' one of my girlfriends friends said, the others giggling as they awaited my reply. I knew that they had seen a couple of pictures I had sent to my girlfriend so there was no point denying it. 'You are all aware that I do!' I said 'in fact I am wearing some panties now' I then said. My girlfriend smiled at me, knowing where this could lead. Her 3 friends looked at each other then back to me 'prove it then' the room was quiet as I stood up, took my shirt off, removed my shoes and socks before unbuttoning my jeans, sliding them down and kicking them away. They gasped as I stood in front of them, wearing only lace panties that did very little to cover my rapidly growing cock....
