"Enjoying the sight?"
Keylas husky voice made Niko smile, and she spread her legs to let her see, what lay between her legs.
"Take a look for yourself. See how my snatch twitches, anticipating what is to come? How stiff my nipples are?"
"Asphyxiation tends to do this. If you have the right mindset, I mean. Like we do. By the way, talking about 'coming', have you, finally, manage to climax? I did already, and I am halfway to my second orgasm now."
"That does not surprise me the least. I bet even the mere thought of doing this with -and to- me has made you wet in the last few days every time you thought of it."
"Of course and why not", a chuckle escaped her lips. "After all, this is an exquisite game, and we are playing it together, at the same time, but you are avoiding my question. How close are you?"
"Quite. The neurotoxin is working a bit slower on me, it seems. I can feel my diaphragm relax more and more with each breath, yet, according to this terminal over there which displays our vitals, I guess I should have around an hour left."
"Me too", a sudden shiver ran through her body and Niko held on tightly to her, allowing her to ride out her peak.
"Mhmmm", Keyla groaned, as it had passed. "As I said. Exquisite. When your climax strikes, I bet it will be gargantuan. Promise me not to fight it and let it happen?"
"Of course", Niko nodded, "Just like during our training sessions."

Right then, as if on command, she could feel her insides tighten up, as the chemical noose wound itself tighter and her rectum clenched up as her world imploded in a shower of sparks.
