Dustin sat, still rock hard as he looked at Ty's elongated penis next to him on the floor. He chuckled as he got an idea. "I wonder..." he asked as he got on the floor, grabbing Ty's cock once more.
Ty moaned as Dustin once again took his stretched length in his mouth, sending pleasure all through his body.
Dustin began to slurp and suck the elongated dick, inhaling deep as he did so. Ty noticed something...different as Dustin sucked him off this time. It felt almost as if he was getting slightly lighter. He looked across the room at Dustin, and sure enough he was right. Dustin was sucking all the air inside Ty out through his stretched penis. Ty moaned as he watched pumps of air travel down his cock. He began to droop, his arms wrinkled as the flopped to his side. His 3 Dimensional shape was slowly fading as he seemingly sunk into the bed.
Dustin kept sucking, shooting a load into his underwear while doing so, still remaining rock solid as he sucked off his brothers elastic piece. Dustin groaned eagerly, watching each suck make Ty become thinner and thinner.
The sensation reminded Dustin of sucking the juice from a near empty capri sun.
Tys body flopped over and piled up in the floor across from Dustin. Dustin gave one final suck as Ty let another load travel down his now flattened length. Each gulp Dustin happily downed as he un latched from Tys cock, letting it retract to his body.
"Damn Ty.. gotta say, you look good like that!" He boasted.
"Uhnnnn..." was all the flat Ty could muster....
