Eva, unable to endure any longer, collapsed onto the ground and lay on her back, saying, "I'm out."
Her breasts, defying gravity, were sensually heaving up and down. And Christian, looking at them, once again couldn't help but wonder if they had really just planned to train seriously…
And moreover, if they weren't doing this just to test his limits, and his rationality.
But even when setting that aside, looking at Eva now, he wasn't sure whether to laugh or cry.
If he had the means to test their constitution, Christian was sure Eva had the higher one, after all.
In the end, without minding that, Christian accompanied his sister, who was able to last five more minutes. He monitored her training, until she finished, before finally saying, "Good work, both of you."
He gave them a few more minutes to rest, before asking, "So, who should I start the massage with?"
