Potential b-day present...

No [decision yet on a birthday present for my BF]; I was thinking about going to a nude beach. =) My BF's birthday is on July 2nd.
Hm... a possibility you might consider would be that illustrated in a post by MacNfries on 26 June 2011 (today). It's post no. 15, here:

in the thread with "Any ideas for hubby's birthday?" on the subject line. For your BF's birthday present, you could (for instance):
1) Order him a "Fleshlight" artificial vagina as a birthday present; see:

2) On his birthday, invite your current lover to come over then order your BF to take off his cloths in front of both of you (except for his panties);
3) give your wrapped b-day present to your (now nude, except for his panties) BF, and order him to open it in front of you and your lover (both of you being fully clothed);
4) explain to your BF his new "Fleshlight" is for him to use as a substitute for you while you are out enjoying the pleasures of sex with your lovers;
5) then, kiss your lover sensuously while he feels you up and undresses you, then undresses himself, in front of your BF;
6) finally, order your BF to remain standing and, continuing to wear his panties but with his cock out, masturbate by "fucking" his new "Fleshlight" while you passionately and sensuously fuck your lover on your bed in front of him.
7) As the final act of your BF's birthday present, you could order him to drain his cum from his new "Fleshlight" and — while you disregard his protests and remain insistent — eat it in front of you and your lover.*

*Your idea re. requiring your BF to call you "mistress" and your lover "master" is a good one. You might also consider requiring him to address your lover always as "Mr. [his last name]" and you as "mistress" or "Ms. [your first name] while you and your lover always address your BF by his first name.
