Internally! As good as a blow job to completion is, there's nothing that quite compares to having mutual orgasms face to face. At least for me, they seem a lot more explosive.

French, Russian or Italian.....

Flesh on flesh.....

My favorite spots to finish...

Ultimately I have always wanted to go in the ass bareback (along with vagina), but of course that doesn't apply in the hobbying world. So my 2 favorites are finishing in mouth of course and finishing on her feet. Whether she performs a footjob (if she is skillful), or jerks me with her hands and I cum on her feet doesn't matter.
Eve is great at footjobs, I know from experience. I hope to see Keyla Keys in the future and see what she can do. She has great feet. Maybe Eve and Keyla...oh my!:-O

inside her, however condoms, those necessary bastards, don't always let that happen.  Second choice, CIM.  Third, combo HJ/BJ when all else fails.

Swim

When it comes to cumming, it ALL feels good, so its just best to let loose during whatever phase your in and just enjoy it.  

For those that cant get more the 1 cup in the hr, my advice, book 2 hrs.  lol  

Cheers
