Now I noticed the little embroidery on them, the word "His" with a picture of a cat. I wrinkled my nose. The cat was positioned right across the pubic... area."His pussy. Don't you get it? I think it's a riot. Her heart-on, his pussy. Oh, I just had to have them."I let out an involuntary breath. "Oh, yea, now I get it. Pretty funny." Where was this going?She continued, "Of course, yours aren't always supposed to look like they do now. You know, with your boner in there, and everything."I blushed.. Unlike Ruby’s, his were rough with 5 o’clock shadow. My lips parted, my heart suddenly beating hard against my ribs. What I was about to do was taboo. It’s only a kiss, I told myself, but I knew it wouldn’t stop at that. It wasn’t only a kiss. It was the prelude to so much more.I couldn’t tell if I kissed him, or he kissed me, the touch of our lips tentative at first, both of us all too aware of our relationship as siblings. There was a moment when it almost ended before it had a chance to. She started to massage her breast as I began playing with myself. She asked me to taste my cum, and I happily obliged. With one hand I pumped my clear precum, and with the other I caught it on my index finger and brought it to my mouth. It was a heavy enough stream to stay connected from my mouth to my cock head. I love when it does that. She did too. She leaned over and looked as if she wanted to get my cock in her mouth. I said it was fine...and she devoured my cock. After less than a minute. Then Tony broke the silence."How long has it been, Dave?" You mean since..." Yeah." I guess it was the night before graduation." Have you ever..." Since then? No." You feel up to it?" Tony asked."Do you have any..." KY? Sure. I keep some here for when I bring my wife." She lets you do her ass?" It took a little convincing but once I showed her who was boss, she doesn't fight it anymore."Dave stood up and walked into Tony's dark bedroom, Tony right behind him. Once they were naked, Dave got onto.
