In college I started experimenting with my BI side. I had a gf at the time and she was unaware that my roommates would fuck me.

However she did know I would occasionally wear her panties and then found some of my panties and my dildo.

How I came to wear her panties. My GF was as big as I was. Often we would go out and stay at her place. I hated boy underwear. Her room had a bathroom connected to it and was shared by her and two roommates. A few times they walked through and saw me sleeping naked. So she had me start wearing her brief panties occasionally to bed. Her roommates would laugh when they would see this.

One day she was locked out of her place and went to my place. My roommates let her in and she went to my room. Well the night before I was horny and wore panties and fucked my ass with my large dildo 10” long 6” diameter it made my 4-5” penis look tiny.

This was left in my closet in my hamper. She went to get a pair of sweats and saw the panties picked them up and then saw the dildo. To say she was upset is an understatement. She text me and asked what whore I had over.

I told her they were both mine and she didn’t believe me. I told her I would prove it. She said ok when you get her you are gonna fuck your ass with this dildo and I am gonna watch. A few hours later I got to my place. I walked in my room she told me to put the panties on and fuck my ass.

For the next 30 mins I ride a dildo in front of my girlfriend while wearing panties. When I was done she said omg are you gay? Like do your roommates know and fuck you?

I lied and said no just curious and she had stuck her dildo in me before. She said hers is tiny and that was during a bj. I tried to say it was not that tiny because her dildo is bigger than my cock. She laughed and said yes your cock is smaller that’s why you eat my pussy.

She told me to take the panties off that were soaked in my precum and anal juices and shoved them in my mouth as she drove the dildo in and out of my ass and gave me a blowjob. I came in her mouth and she came up and spit the cum in my mouth.

A few days later she put me in her panties and fucked me with a strapon for the first time.
