I'll never know who...

I am tied to the bed with a blindfold..you tell me you have a surprise arranged. I hear some movement and sense someone straddling my face; you do this all the time, but somehow this feels different. My face is covered and my tongue forced deep inside a wet pussy...it's taste and texture feels different..a small adjustment above and I am now pleasuring a tight asshole...I can usually slip my tongue right up inside yours, but this one is tighter. For the next 30 minutes I am moved from pussy to ass to clit until I can feel a shuddering and wetness covering my mouth. My face and hair are used to wipe away most of the wetness and I am alone again. My wife then tells me that was a very close friend of ours....but I will never know who...
