Finally the plug sits firmly in my asshole and fucks it. His vibration massages my prostate - and he moves back and forth in my rosette - as if he were a hard cock copulating my asshole. Some pre-juice collects on my glans and I can no longer take it and have to touch my penis and jerk off - until the sperm squirts. The sticky seed ends up on my stomach and on my balls. The sack had a lot of fun with orgasm today.
