People keep suggesting predators. Sigh, I must admit I have absolutely no attraction to them so there is almost no chance of that happening. I did consider a net trapped Black Beauty tickled by a predator. Though that's as far as I may go.
Ah, apologies, I mistaken you for one of my regular watchers. Black Beauty is my female xeno; quintonquill.deviantart.com/ar… based on the original 'old chap' design from Alien. I have her frequently tickled or just being sexy.
As for predators. I love them solely for their bad ass hunter awesomeness. I can't fetishize that. I love the, I think they are awesome but I can't slap a pair of breasts on them.
