I slowly left my chair and got on my knees on the deck beside them. I was a bit timid to put my mouth so close to the point where my son and wife beca...e one. So, with my left hand stroking my cock under the couch, I brought my right hand up to her clit. She placed her hands above each of his shoulders and leaned back. She looked at me with a determined look and said "I told you I wanted your tongue on my clit, I can finger myself." Yeah, dad, give her what she wants. I want to fuck her good,. I wanted to scream “GET OUT!” because I wasn't finished, but once again the rational side of my psyche came to the fore front and I let the adrenaline rush subside. Then I heard Amy say “It’s okay girls. Grandpa knows our secret.”Oh my god, she's going to help me!The girls stood motionless, staring at us. I smiled and said “You have to trust me. I saw you all together in the hot tub last night. And, like I told Amy, there's nothing wrong with being curious. And I heard about Amy's. No bullshitting this Blondie. I looked right at her and told her the truth. "I get a blowjob whenever someone gets a ride on my boat." Surprised, but not shocked, she asked, "so if you give a ride to a guy, do you change your policy?" "No", I replied, "guys suck cock too." Now staring at me, she reached over to nudge her redheaded partner who had lain back pussy wide open. "Did you hear that?" she said? "He's queer." The redhead replied with a giggle and told her "no he isn't, he just likes to. I'd sell whats left of my soul to go cock to cock with him.This went fine until the one weekend when my wife was away on some friend's birthday trip.I wasn't giving man fun too much thought by then. I was enjoying a little bit of freedom by going out on the town with some mates - all of whom are straight and have no idea of my secret desires. So the Saturday passed by in a blur of football and drinking. But I normally have a few drinks on a saturday, though maybe not to the extent as I had that.
