About six months

She purses her lips for a moment, but keeps up her ministrations.

"About six months, I think,” she giggles. "I lose track of time these days. Like when you're on vacation,and you forget what day of the week it is... I lose whole days between all the fucking.” She looks up at her son. “Does six months sound about right, Baby?"

Mike pauses his game to think for a moment. "Yeah, I think so. Question is, how did John forget?” He gives you a nudge. “You’re the one who suggested it to Dad, when we were both feeling mopey about the fact that Mom was at your place all the time." He grins. "As usual, it was a great idea... I got to go further with Patricia's mods than the old Dad ever let me go with Mom."

Another piece of the puzzle. Maybe April's at my place now?

"Yeah, well if I'd known how awesome these balloon-tits would be, I'd have been all for going further with April back then,” Patricia says, pausing to lick your cockhead as it bobs up into her face. “Ah, well. Live and learn."

Mike still hasn't gone back to the game, and is gazing hungrily at Patricia while she slides her tits up and down your shaft. "Hey man, do you mind if I join in? Like I said, I’ve only used her once today."
