You and Betty had always been good friends, sticking together in college like glue. So it was only obvious that you two would stick together in a... different way.
When her father became obsessed with capturing the hulk, he kidnapped both of you and forcibly irradiated you into Red Hulks.
After a few years of being forced to be weapons, you were both eventually freed by the avengers. Though it was unlikely that either of you would ever be normal again.
But you both decided to make it work. Eventually tying the knot! Now, you both stand inside an active volcano, in Hawaii for the first stop during your honeymoon, feeling the comfortable warmth against your hardened red skin.
"Wow, it's so beautiful in here~" She says with a smile. She walks over to a small pool of lava, dipping her hand inside.
"Ooh~ That's very nice." She looks over at you with a smirk. "Care to take a dip with me~?"
She strips out of her clothes, her soft red skin tantalizingly on display, and sinks into the lava, treating it more like a Jacuzzi than lava.
"Mmm~ Oh this is great~" She says with a soft moan.
