Holding Pee Till I Piss and Cum on Myself

I remember this one time when I was really into holding pee until I thought I might explode, just lying there on my bed with my legs squeezed together, feeling this crazy pressure building low in my belly while my fingers were already working in slow circles. The desperation got so sharp that every little twitch made me gasp, and I kept telling myself just a few more minutes, but then my body just gave up and I let go, and the warm rush flooding over my thighs synced perfectly with the waves crashing through me as I came undone, my whole body shaking and soaking the sheets beneath me, that mix of heat and release being the messiest, most satisfying thing I’ve ever felt, and honestly, I just lay there in the puddle, completely wrecked and grinning.
