[MFM] knowing too much

One evening when me and my gf’s were drunk we got some cocaine. Had a great night but when she fell asleep I for whatever reason looked on her phone it was about 4am for about an hour I was scrolling through seeing if I could see anything that would turn me on. I found her girls group chat and she’s posted a pic of her dildo I’d night for her ( about 9” and chocolate brown) she said how much better it felt than sex.. her friends kept mentioning this guy called Ed in her WhatsApp group and saying she should get back I with him because he had a huge cock.. I was so curious and turned on.. I went in her Snap and scrolled down and saw his name .. I clicked on the chat and scrolled up.. shed saved a pic he’d sent.. my eyes widened.. it was a picture of his huge uncut cock in his hand.. a huge vein running through it and thick as my wrist.. my heart sank.. he was twice my size . I took a picture on my phone so I could look at it again .. after that I could only imagine her fucking him when we were together
