You decided to stay in your little brother for a little longer. Your pervert mind was entirely done yet. Cumming as Thomas felt so good, you wanted to cum as him again. You started searching for objects that could act as sexual stimuli. In the cabinet next to the mirror you found an old toilet plunger made entirely out of rubber. "This might be good" you say as you pick it up. You try to use the toilet side of the plunger to suck on your ass, but it doesn't cover your ass enough to have effect.
"That's too bad" you say and you turn the plunger around. "This should work tho." You look at the rod of the plunger. It is about 10 inches. "No dick can compete to that" you say as you put the plunger on the ground with the rod facing up. You start stroking your dick again and quickly have Thomas' 6 inch cock laying in your hand. You then slowly start to squad down with your ass hanging above the plunger's rod. You start stroking your dick again while the plunger slowly enters your ass. "Aghh" you gasp as you moved down a little to quickly. The plunger is now about 5 inches into you ass and you are about to cum again. "Yes, Yes, YES" you say as the cum starts shooting out of your borrowed cock.
You're shocked when you see the cum has turned green, and slimey. Thomas' body is ejaculating you. You try to get up as more and more slime shoots from Thomas' dick, but you have lost almost all control of Thomas. As you try one last time to get up you slip and fall with all your weight on top of the plunger rod which has now entered Thomas' ass with all it's 10 inches. You can only feel a light sting of pain before completely being forced out of Thomas' body.
When you come around again you notice you are your own slimey self again. In front of you, you see Thomas lying unconscious on the bathroom floor with a toilet plunger 10 inches deep into his ass. "Oops.." is all you can think of while trying to hold your laugh. "What now..." you think.
