To their joint delight, Megan took the smooth vinyl shaft in both hands and started jerking it rhythmically. The whale cooed his approval, the temperature of the air inside him rising slightly.
"Mmmm. My big boy likes, huh?"
She started jerking faster, and faster, gasping as she felt her soft friend warming. "That's it!" She praised. "I want to see if you can cum!"
Apparently, he could. With just a little more effort, the whale moaned as his air boiled inside him, turning to a condensating steam, heating up his soft vinyl to the touch and inflating him tighter and fuller. His penis jerked suddenly in Megan's hands and to her surprise, thick white fluid poured from an unnoticed hole on his cocktip and all over Megan's body. It took a full 10 seconds for the giant inflatable orca to stop ejaculating, by which point Megan and the carpet below her was almost completely soaked in sweet smelling jizz.
The balloon lover panted, thrilled, and gasped. "My God!" She panted. "You're my favorite toy, now! Was it nice?"
"Mmmmmmmmmmmmmmmmmmmmmmmmmm!" The whale reverberated loudly, the last bits of cum drizzling from his giant cock.
"Good!" She said with a laugh. "Now let's get you down to a more manageable size and go have a shower."
