Just a little more...

“Actually, now that we are in position...” you begin, “I want to see your scrotum grow for just a little while longer.”

“Oh...” You can hear Franny’s disappointment in her voice. “S-Sure...anything for you. It just *really* is starting to hurt...badly.” Franny’s voice starts cracking with pain.

You slap the side of Franny swollen balls rising in front of you. She cries out in pain but doesn’t complain. Her skin is taut like an overfilled balloon. You squeeze her balls from either side and feel some give left. Either the hormones are allowing her skin to grow to keep up or she still has more room to grow. Her swelling orbs have you turned on to the max. They are round like boobs but you love the firmness of their overfilled state. Franny moans in pain from below you, your gentle carress making her hornier but causing her cum production to increase. You can feel your hands moving slowly outward as you rub Franny’s oversized organs.

“How are you doing, Franny? You look amazing and so sexy with all this cum!”

“F-fine...you want me bigger? Keep rubbing my balls like that...ohhh...”Franny trails off, the pain now too much to speak.

You know you should give her release, but her size has you excited. Her balls are pressed against you fully now. Slapping them elicits a sharp intake of air from Franny, but also the ripples through the cum inside transfer from her skin to your skin. You slap them multiple times in quick succession, harder and harder. It’s like a massage from her balls to your favorite swollen parts. You are about to cum!

“Franny, ugh, I’m going to cum in you!”

“N-n...ooohhhh!” Your own swollen load joins your overfilled partner’s. Your hands are slapping her balls so fast they are vibrating. Her balls hit your chin as they swell further. You turn your head downward and lick her. You can hear Franny crying.

“OK, Franny,” you say as your orgasm subsides. “Now!”

“I-I-I can’t! It hurts too much to get excited! I can’t cum!”
