Looking to share

[ThatGuy]

Hey guys, so I've been thinking about sharing my GF with someone for about 4 or 5 years now, it all started when I found out she was on a dating website and chatting explicitly to other men.  She is now 28, chubby with big big tits and a nice round ass.  She was a virgin when we met and to my knowledge i'm her only one.  Anyhow, when I read the messages that she was having with all these men I felt hurt, angry, let down but strangely I felt turned on....a lot, I had an erection reading them lol it was so unusual but since then I've had the fantasy of seeing her have sex with someone or maybe a few people but she is very shy and would never do it...maybe if there was alcohol involved, I'm not sure....how should I go about this?  I have pics of her but not sure you want to see 'em?

 

Thanks
