I was changing my clothes getting ready for a date with my girlfriend Mandy when suddenly heard my bedroom door open. I turned to see my roommate swinging the door open wide and walking right in. Beth was a good friend and a good roommate, but she had no sense of personal space or boundaries sometimes, so in she strode catching me in my underwear.
This wouldn't have been bad since she had seen me in my underwear before under similar situations, but I wasn't wearing my normal boxers. I was wearing bright pink lace panties. Yes, you read the right bright pink panties. So needless to say, I suddenly felt quite embarrassed at being seen this way.
"Holy shit Beth!" I yelled. "When are you going to learn to knock?!"
"Sorry." she said half giggling. "I didn't know you were getting dressed." I then watched her eyes lock on to my waist and get bigger than saucers as she saw what I was wearing. As she took it in, she suddenly busted out laughing.
As she nearly doubled over from fits of laugher she said, "Brian why are you wearing panties?!"
I was thoroughly embarrassed at this point and probably matched the panties I had on. I tried to pull on the jeans I had laid out, but when I moved to grab them, Beth was too quick for me and snatched them saying, "Oh no you don't! You have some explaining to do and I want to enjoy this." she said grinning widely.
"Come on Beth." I pleaded. "This is embarrassing enough."
"Start explaining mister." she said firmly before stifling another giggle.
"Ok, ok." I said resigned to let her embarrass me. "It was Mandy's idea. She said it would be like she was with me at all times. I wasn't particularly keen on it, but she said she thought it would be cute, so I agreed. So now anytime we go out I wear panties she gives me."
This admission brought another giggling fit from Beth as I burned from embarrassment. "Wow this is gold!" Beth said as her giggles subsided. "Big tough guy wearing delicate pink lacy panties! I know you were really into Mandy, but I didn't know you were that into her."
"Please Beth, this is embarrassing enough." I said. "Now can I get dressed?"
"Oh no." she said giving me a wicked grin. She shut the door behind her and said, "If you want me to keep quiet about this it's going to cost you."
I gulped as I said, "Cost what?"
She slowly unbuttoned her jeans and shimmied out of them and her panties. Though Beth and I never had any sort of sexual relationship I was still a guy and seeing an attractive girl strip had the expected effect and I felt my dick start to rise in my panties.
