My story, more or less pt.3

I came back with all my things and put them on my bed - my plan was ready and I finally could take action. I put on my pantyhose and heels, making me hard instantly. A very noticable bulge arose from inbetween my thick thighs, lightly staining my very deep den black pantyhose with precum, the friction turned me on even further. Hell, I bet I could've ejaculated from just that! Wasting no time, I got my ropes ready - knots visualising in my head. With the red rope I tied one end around my ankles - securing them firmly and the other one around my neck. I needed to bend myself backwards a little, as the rope was barely reaching. Just when I secured it, I started to feel the grip of the silky rope around my neck - it was firm but not overwelming, I still had no issues with breathing so I went onto the next step. I tied the second rope around my thighs while leaving a little coil for my hands near my butt, that would fasten once I got them in. Then I used another pair of pantyhose as a blindfold - tying them around my eyes, so that I couldn't see anything. Finally - I lowered my hands into the coil and fastened it. Now I was officially bound for the first time in my life.
I rolled onto my stomach, feeling my boner pressing into my belly. My ankles held as closely as possible to eachother, I could feel every move on my neck, as if somebody was gently squeezing it.
Needless to say I was in absolute heaven, even the slightest move reminding me just how restrained I was. Not wanting to stain my bedsheets with cum that I felt was inevitably approaching - I rolled over to my back, effectively pinning my hands and legs together. By then the pantyhose was soaked in precum in the place where it rubbed against my hard dick. I couldn't move either of my limbs, not even raise my head as my neck was still tied to my ankles! After tugging a little against my bondage - effectively edging myself, I finally felt the extatic feeling of crossing the line.
I panicked even more than while during my self-suck session, as I didn't even think of what to do in that case! I seriously doubted my ability to cum without touching myself, well up until that moment...
