I was invited to a party recently and I took my girlfriend with me (I am a guy ). Well, we had some fun. It was over the midnight when I entered a lonely room to have a smoke. The lights were dim... and what I saw was my girlfriend and Mandy (our mutual friend) in a bed together.
They were naked, you know... The two girls were doing all these naughty things
. Mandy sucked my girl's pussy. They were so into sex that they didn't notice me. I was drunk and felt shocked first. As I watched them getting on, I started to enjoy it. I never knew my girl was bisexual. I am intended to discuss it with her. Maybe I can join her and Mandy for a threesome
