The Girl in the Lab.

Breasts.

Two big blobs of heavy meat lay on Yuuki's face.

They were pressed against his face, and the sensation felt quite distinct.

Initially, the sweet scent of the cleavage of these two big meats, as well as the pressing force against his skin, felt refreshing, especially since these meaty balloons were so big and soft.

As these balloons continued to make contact with the face, there was a slight squishiness as they molded to the contours of Yuuki's face.

"Hummphh!" Yuuki uttered loudly.

The weight of the meaty balloons added pressure, which felt somewhat heavy but not necessarily uncomfortable, much like having a gentle pressure applied to the face.

The surface tension of these breasts, combined with their very meaty texture, created a sensation of being enveloped, almost like a soft, juicy pillow pressing against the face.

"Yu, Yuka... you're chok──!!"

The young man coughed heavily.

"You're choking me!"
