I got a shocking surprise for my 40th Birthday.....my ex-wife was treating me to a lovely sensual warm oil massage in bed, when she blindfolded me.....she then told me to relax, and as I felt her lay beside me fondling me, I felt a hot mouth close over my erect cock-head......My wife then pressed her stiff nipple to my mouth, so I knew it was not her! I felt a tongue rubbing the underside of my cock, and hands on my thigh and belly and a soft 'mmmmmff' sound as my cock was getting sucked.....I had never been as hard, and my wife was pressing her tits to my face, but the shock I got was mind-blowing.....the blindfold she had put on me slid up a little, and I was stunned to see it was her daughter Toni with her mouth around my cock, naked apart from a pair of fishnet hold-up stockings....! My wife (Simone) realised I had seen, and just breathed 'shh, it's ok, it's ok' so I of course just lay there, stunned, but loving it!
