That was uncomfortable to see, Amber was crossing all boundaries. I don't fault Ocean too much, he has to maintain a difficult balance between sexy and real, one might miss it fairly easy. But I do think that if we considers that Nika finds it sensual it makes a lot more sense.
We mock Nika but the boy is scoring 10/10 young woman while having ED, Ocean had to nerf him, otherwise SG world would end by overpopulation in 9 months. The sad parts is that he does not needs to fuck, only Bella and Nami needs it. Maybe this is the way the throuple begins ?
