lastnight my gf and i went to a friends birthday21st and my best mate who is a black guy was there my gf and him fucked once before i went out with her. at the party my gf wore a tight white dress which u could clearly see her black g string through she looked hot anyway i went to bed ******* and my gf came to bed too but i couldn't sleep straight away but after 5 mins or so my gf got up and kept drinking with everyone so i gave it a few mins and looked out the window and saw my gf chatting to my mate which is cool but she had her dress lifted up obviously showing a bit more skin in no time she was sitting on his lap laughing and having a good time until i walked out but i wish i just stated and watched cause i reckon they would of fucked but maybe next time
