Roughly, hurting his dick

They had stripped and stood naked facing each other.

"It's best we just get to it" she said, trying to act dominant and grabbing the head of her brother's cock between all her fingers, then squeezing and yanking.

The cock head was soft, and compressed to her touch, but too much. Since his foreskin was below her fingers, she just pinched and yanked his dick!

"Ah my fucking dick! You pinched the tip!" He said, rubbing his boyhood.

"Ah, did I hurt my brothers big dick? Here let me try again. Im sure your manhood can take it" She said, moving his hands away and placing her hand on the head the same way, and starting to squeeze. This time slower, so she could see.

He started to squirm, and she loved the power she felt by holding just a small part of his package and owning him. She saw him try to resist, so she increased power of grip.

Tara felt light pressure on her nipples, then a squeeze. She was so enthralled by pinching him she forgot her erect nipples were out, and he was increasing pressure as well.

They looked into each others eyes, both slowly adding more pressure to their siblings genitals. Even though the pleasure of having her nipples turned to pain she said "No way your boy parts can take more than my girl parts" and squeezed his dick harder.

Wanting the pain on her nipple to stop, she decided to really pinch. She gave him a look to let him know to be scared.

She was sure he couldnt take a squeeze harder than last time, so she gloated, even as the nipple pain became intense. "I hope your cocks ready for this!" And put her full strengh into the pinch.

However, unlike last time Jack had leaked some precum, so he slipped right out as she triped to pinch the very tip. As his dick left her grasp she felt weaker, and focused more on her tits, which now had too much.

"Okay ow okay you win release my tits! I didn't think it'd hurt so bad!" But he kept squeezing, just less intense. Her nipples enjoyd this level of pressure, it was like the warm feeling if cumming, but weaker, but also she was ready for it to end. "Okay your big dick beat me this time, please, let me kiss your penis til it feels better.
