My heart pounds.  Their lips meet.  Their wine glasses set on the edge of the hot tub.  My cock breaking, their feminine lips parting, tongues tentatively exploring each other.  I moan as my wife caresses our guest's large breasts over her bikini.  As they break their kiss, "That was way hot," our guest smiles.

My wife slides her hands up our guest's breasts and reaches behind her neck, untying her bikini top, "Shall we continue?" asks my wife

I continued leaning back, watching my wife explore another woman, knowing this was going to our suite.
