Give him a diagnose...

"Mister Peterson... I think you have something swollen on your legs..." You said to him while pointing at the lump on his pants.

"What... no... this... this isn't swollen... I'm fine really..." He nervously replied you.

"No you have to treat such a swollen... I am a nurse please let me help... pull over your car and let me take a look at it..." You insisted to give him a diagnose on his swollen leg, looking at him with with genuine worry on your face.

"Well... no... it's... it's okay really... I'm fine... it's nothing really..." He stuttered as he replied you.

"Please you have been so kind to me to drive to the hospital... this is the least I can do... don't worry I am a nurse... I am used to see these kinds ot things..." You explained to him, and you move to the side, this makes your loose shirt fall off your shoulder even lower that it's supposed to, unintentionally showing him the smooth skin of upper parts of your firm breasts just above the nipple, plus your ridden up skirt is now giving him a full view of your cute pussy.

His eyes widen as he stares at the sensual display of your breasts and your pubic area, this effectively makes the lump on his pants grows larger.

"Pull over mister Peterson... your swollen is getting bigger... let me take a look at it... it's okay..." You said to him again to convince him.
