I really like the idea of watching my GF fucking another guy. It's a major turn on just thinking about it and chatting to guys on hear about it. I've shown some guys on here a pic of her and asked what they would do to her which has been fun!

I got virtually cuckolded whilst i was 16 and my gf was the same age, we dated for about 3 months and then she decided she wanted to have sex with me. She saw my 4.5" penis and well you can probably tell what her reaction was.

Then she started dating this other guy and kept sending me pics and clips of her fucking her new guy and she told me he was 9"... I couldn't help but wank to them

She must have had a few cocks before you then, if she knew 4.5 was small.
