"But first, I want to have a little fun, " says the woman.
She lays beside you on the bed, and begins to massage your shaft. You realize that you are nearly eight feet long, but are still very thin, measuring only 12 inches in diameter. You quiver in excitement as you stiffen. A little precum drips out of your tip.
"Not yet, not yet, " says the woman, and she moves up to your tip and begins to lick around your urethra.
She positions her vagina in front of your tip, and tries to force you into her. But you are too large, and the woman grunts in frustration. You begin to wilt a little, and the woman quickly changes position. She moves to your base, and begins to massage your testicles. They are immense, each weighing about 100 pounds. You feel liters of semen churning in them.
The woman senses your excitement, and increases her efforts. She begins to rub her soft nude body against you shaft. She pulls your base close to her groin, so she can rub your shaft and your balls at the same time.
Suddenly, you feel the familiar orgasmic rush, as you fuse with her groin.
"Wait, wait, stop, " you scream. "Don't cum! Don't make me cum!"
The woman wakes from her own orgasmic bliss, and looks down at her groin.
"What the hell! " she says, staring at the large whale penis now fused over her groin, replacing her vagina.
"This happened once before. If I cum .... I mean, if we cum, you will turn into a whale. We have to stop, " you say, beginning to wilt.
"I should say so, " says the woman angrily. "I don't know how I would explain how our house go destroyed. Much less, I don't think I could survive as a whale out of water."
You struggle to detach yourself like before, but the woman screams in pain. She pulls you back forcefully.
"Stop, you are killing me, " she screams.
"I did it once before, " you say.
"When you were this big?" she says.
"No, " you mumble.
"Well, then stop. If you pull away like that I think it will kill me, " she says.
"Well then, give me another jellybean and make me smaller, " you say.
She backs away from the bed, dragging you along the sheets. The sensation is stimulating, and you feel yourself getting stiff again. A little more precum drips from your tip. The woman rapidly grows. Her arms and legs get longer and thicker. Her skin develops a smooth sleek texture. A small fin sprouts from her back, and a tail begins to develop. The changes stop when her head smacks the ceiling, the pain causing her to snap out of her pleasure. She slaps your balls painfully.
"Stop that! Or we will both be in trouble, " she says angrily.
"Sorry, " you moan. "But it's kind of hard to control myself sometimes."
The woman looks herself over and sighs. "Well, at least it will be a little bit easier to move around now. How big do whales get anyway?"
"I think blue whales are about 100 feet long and weigh about 200 tons, " you say.
"Great, " says the woman sarcastically, as she examines her larger body.
"Well, what do we do now? " you ask.
"Shut up and let me think, " says the woman.
As you wait, you feel yourself getting aroused again.
