And, frankly, if I were Robbie, I'd be wanting to take her to bed for sure. She is a doll. Short blond curly hair, about four inches shorter than Robb...ie, maybe ninety pounds or so, and, as I now strongly suspect, 34-B breasts which obviously my son is well acquainted with.Now, I told you that I didn't confront Robbie. Here's what I did do, just try to understand.As I sat there at his desk looking at the email, all I wanted was to witness their first lovemaking, I wanted to watch. I wanted to. I never felt so good as when my cum began exploding from my cock. Less than a moment later, he began to cum as well. We continued to stroke each other as two geysers of cock cream erupted into the air and splashed down on our arms and legs and bellies.When we could move again, we walked into the shower. We washed the cum and the sweat and the dirt from one another as we explored each other's body with eyes and hands and lips. When Dave's cock grew hard once more, I dropped to my knees and took. There before me was a gorgeous ass (had Roger shaved this specially for me?) And a beautiful big pair of balls hanging beneath a monster cock. I hoped I could be a good enough sissy to deserve what was on display before me.Looking Roger in the eye I teased the head of his cock. It was a beautiful mushroom, soft and spongy and with its coating of pre-cum it tasted of man. Knowing he would probably cum quite quickly, I decided to focus on his ass hole and balls. I knew Roger would have plenty of. Lets, see. You asked why you weren't pregnant.After pausing to gather his thoughts, "How do I explain this," he had told her."Well, just before I got divorced, my wife was pregnant. She had told me she didn't want to have any more children. So while she was carrying my son, I had a vasectomy."She demanded I have a vasectomy."That way, when the baby was born and we started having sex again, I wouldn't be producing any sperm and she didn't have to worry about getting pregnant again."Claire really.
