My girlfriend's friend saw my micropenis

Me and a friend of my gf's named Jamey were over at her house for a studying session. It was our final year and we were all freshly 18. At some point while Jamey was in the kitchen I got up to use the restroom. When I finished up I went to pull my pants up but it got stuck under the edge of the sink (it was a tiny side bathroom connected to her parents room.) Sure enough as I turn to pull my pants out from under the sink Jamey walks in on me. After locking eyes I see her eyes drift down for a split second before she covers her mouth and yells "Sorry!" before slamming the door shut. Afterwards when I left my girlfriend was bursting out laughing and me and Jamey were both red in the face with her profusely apologizing. Both of us were embarrassed but it was an obvious accident so I quickly forgave her and we pretended if never happened.
