Grab Louise's gorgeous breasts.

With Louise's bumcheek in his hand, and her lacy pink panties on display, it took everything in him not to come with her rapid pumping on his shaft. But, he reminded himself, he still had one free hand.

He moved it from the table and to her waist, slowly tracing up her belly until his fingers rested beneath her breast. In one quick movement, he moved to rest his palm on the soft mound on her chest. He squeezed it once, and her lips parted in a stunning grin, but he wasn't yet satisfied.

He quickly unzipped the hoodie he was feeling through and opened it down to her belly, exposing her less clothed chest beneath. He cupped her breast again, now able to feel the hard nipple beneath pressing against the thin fabric of her shirt. Louise moaned as he fingered the little bud, taking a mental note that the area was a sensitive spot.

Her lustful gaze met his, and the situation finally caught up to John; he was being masturbated by his little teenage sister, holding her breast with one hand and her ass with the other, her sexy laced underwear exposed to him. It was too much to handle, and he felt himself building to a completion he wished he could stall for even another moment.
