I want my gf to cuckold me! I'm not into cross dressing or being locked up or anything.  I have a 6 inch cock but don't have the skill to make her cum at the moment.  She loves when I eat her out though.  I'm the only guy she has ever had sex with.  My dick is also the only one she has ever seen in person.  I WANT TO GIVE HER MORE! 

It has been my biggest turn on to think of a huge cock sliding in and out of my girlfriend's pussy.  I want to hear her moaning as he makes her cum harder than she ever has before. I want he to look at me as she gets fucked by him. Then I want to hear him moan as my girlfriend's pussy milks every last drop of his cum into her.  And when it's all over, I want her to grab me by the back of my head and shove his cum covered cock into my mouth so I can clean him up and suck out any more loads he might have.  With my girlfriend talking dirty to me the whole time.  Then it's her turn.  She sits on my face and pushes his load out of her pussy and into my mouth.  I would love to be dominated by them both and used like the slut my girlfriend already knows I am. One time she was giving me a handjob, she kept calling me her bitch and a dirty slut.  It was amazing! I came so hard that I moaned loudly and came in my open mouth.  She looked like she was worried I would be mad.  So I smiled and swallowed my cum.  She looked shocked and said "wow! You really are a dirty little slut aren't you? ;)"

One day when we were getting lunch at a sub place, she said "I don't know if I want a 6 inch (my size) or a 12 inch."  I laughed and said "that sounds pretty fun out of context." She laughed and said "I don't think I could handle 12 inches."  I got hard instantly and said "who knows. You might love it."  She smiled and looked like she was imagining it then gave me shrug like she was saying "maybe 0;)".  It got me so turned on to see her face after I said that.  Just a little more of this and I'll be her cuckold yet! 

Another time, we were playing gta online and a kid was arguing with a black guy.  The little kid said "shut up you idiot and suck my big dick!" My girlfriend just laughed and said "hey kid, he's black. So he probably has a huge dick." My cock instantly was rock hard. I loved how she said he had a huge dick in front of me.  So I started trying ways to bring it up again.  

"So, just because he's black, he has a huge dick?"

"Ya, it's pretty well known that black guys have huge cocks."   

"Would you try it?"

"i don't know. Sounds like it would hurt." She said as she made that face as if she was imagining it.

this is the closest I am getting to my fantasy at the moment.   

Every time I think about my girlfriend being fucked or making me suck a cock for her, a rush of excitement comes over me and makes my cock throb.

Unfortunetily this isn't in the near future. I told her about my fantasies and she just thinks it's weird. Hope she considers it more. So that's why I'm here posting captions.
