Give Bran a helping hand

"Here, let me show you how it's done."

You sit him back up.

"Place your hands behind you and lean back a little. Watch Father. Don't take your eyes off him."

He looks at you and then slowly swings his gaze to your naked Father, whose strokes have sped up somewhat, and lengthened.

You place your hand on his cock and it twitches. His tiny member grows only a small amount before reaching full tension. Your fist almost completely obscures it from view as you begin to slowly massage it.

"Jon, this feels funny. Really good, but really funny too." he squeaks, his eyes still glued to your Father's cock.

"Relax and enj..." you cut off as you notice his pecker squirting in your hand. Small spurts of cum that end as quickly as they began.
