Reach between his legs

Feeling yourself grow excited at what's to come, you carefully reach between his legs and inch your fingers closer and closer to his balls. Once you're a few centimeters away, you quickly and firmly lock his squishy orbs in your grip, flexing your fingers and relishing the feeling of having his entire masculinity in the palm of your hand.

"W-what!!" Alex shouts in surprise as he feels his tender and aching nuts in your grip once again. He tries to turn around to look at you, but you tug upwards hard on his nuts from behind and **** him to bend over and face the floor.

"Sorry, no peeking!" You say with a giggle and a wide smile. You continue to lift up while twisting and crushing his nuts in your grip, enjoying the different and unique cries of pain he made. Nothing was more enjoyable than this. Just slightly putting a bit of **** into your grip would make him tremble and beg for mercy. It was too easy! Honestly it seemed like a joke that nature left him with these **** things. Poor boys. Well, not your fault!

"Please Lucy you already crushed them earlier! This has nothing to do with self-defense!!" Alex desperately pleaded, trying to reason with you. Even the slightest bit of pressure of your grip caused explosions of pain in his already swollen and aching pair of testicles. He could feel the familiar nauseating ache travel from his nuts to his stomach as he tried to stop himself from throwing up again.

You pretend to consider for a moment and lighten your grip, before crushing down on his nuts even harder.

"What do you mean? I'm learning how to make sure an attacker never even tries to go against a girl ever again!" You laugh cruelly and move your grip to hold the base of his sack, pushing his balls to the bottom and trapping them there. You then ball up your other hand into a fist and punch his trapped nuts as hard as you can. A resounding and satisfying smack reverberates throughout the bathroom as you feel his testicles compress and flatten against your fist. Your stepbrother makes a pathetic squeal and tries to collapse to the floor. Unfortunately for him, you hold him up with his nuts alone, multiplying his pain to unholy levels. Alex could feel his nut chords stretching and was terrified they were going to snap under the pressure of his body weight. The pain was unbearable and he threw up again, feeling like his time as a man might not last much longer.

You continued to hold him up by the nuts for a moment, considering how merciful you were feeling.
