Ok

You stand up facing away from her. You fumble a bit and turn around.

Nadia's pupils widen when she finds a palm from her nose the sight of your egg-like testicles resting on your semi-lowered shorts, with your penis covered with difficulty by your shirt.

Nadia: "Oh my God, they're huge." She stares at your jewels carefully and after few seconds she moves her little hands slowly and decisively. Her touch stimulates even more the erection you are trying to hide from his gaze; your testicles rise slightly and she giggles excited.

Nadia: "They moved. They are hot and slippery, eheh" she chuckles and you feel her grip getting firmer "I can barely hold one with an hand ..."

She starts squeezing the right testicle in the middle between her thumb and forefinger, and a moment after you start to feel sore it shoots up like a bar of soap.

A faint moan escapes you, but she doesn't seem to notice and giggles

Nadia continues to manipulate your gonads lesser gently.

During a particularly impetuous groping, you startle visibly.

Nadia: "Oh? Am I hurting you? S-sorry, I knew they were boys' weakest point but I didn't think they could be so delicate," she says, stopping her explorations and blushing slightly, but always holding your genitals in her hands.
