A ways away

So I have a new girlfriend who is a virgin (that'll end shortly she's dying for it)

However I did let her know one of my fantasies is to watch her with another guy. She doesn't see what I get out of it and said down the line she would do it for me.

So far she's responded really positively to me just going down on her and breast play. We got her a toy and she said it almost felt kind of too small and she likes what I do with her more. She has a very high sex drive and always is telling me she's horny even though we do not get the spend the most amount of time together.

She isn't super into black guys and isn't overly keen on trying anal.

I haven't really told her what cuckolding is, right now she just thinks I want to watch her hook up, but she says I should get involved with the other guy too.

Honestly as someone who has not tried this type of relationship before, I feel like theres some positives out of this and some negatives so far.

So although this might be a year away...what do you guys think of the situation? Am I likely to get cuckolded?
