They each other's breasts

The string around each other's chests tightened, squeezing their breasts with a collection of fine wire collected into thick rope. It was like their hands were pressing down on each other's breasts, and the thought made them feel just the bit hornier. The sensation was burrowing into their strings, like their own fingers were grasping into such flesh. They wanted to grope such flesh, they wanted to squeeze it, the horny thoughts were overtaking their angry thoughts.

Their stands reached out to punch with their free hands, but instead ended up grabbing the left breast of the opposing Jolyne. The two gasped as they felt such a sensation, bringing them back to reality.

"So it seems like you're also a pervert," Jolyne said. "I'm sure you realize that makes you more suspicious!"

"Like you aren't doing the same thing," Jolyne said. "Your lack of self awareness is even more suspicious!"

Their free hands squeezed intensely on their breasts, twisting and squashing the flesh as hard as they could. The hands that they turned into string were reverting back, and the two now used both hands to grab each other's breasts. Squeezing and pulling as hard as they could, they tried to inflict as much pain as they could on each other.
