Ok, first off, I'm not talking about doing twin providers, although that is still on my bucket list.  

My question is, if you are a twin, or if you did have a twin, would you do a M-M-F with him?

I ask because a year ago I meet with a touring provider and had a great time.  Then this fall I take a guys only trip with my identical twin brother for a football game in a location that also is her home base, and they get together based on my recommendation.  I meet with her again earlier this year, and she remarks that my brother and I are her first twins, and that she'd like to do us together next time she's in our area.

So would you?  or does the thought of being in a sex act with your brother just not feel right?  I'd appreciate some thoughts, and also, any comments from the ladies on your thoughts.

Thanks
