Nipple torture while masturbating makes me cum hard

Crossdresser in lacy lingerie with nipples clamped and stretched hard. The pain and pleasure makes my dick stiffen and start to drip precum. The ballstretcher pulls my nuts tight and I crush and stretch them as far as I can. My balls are bouncing hard between my thighs and fist while I pump my dick, and my legs start twitching. I can feel my cock get harder in my fist, them let loose with a cumshot that makes me stagger and almost fall down.
