cock swelling then throbbing

[PileDriver]

that feeling when a cock swells...then throbs violently

I enjoy that too, especially when it's doing that while in my mouth.

I've only felt that once ... inside my ass!

I think the top was trying to last longer, but got too close. He stopped thrusting, but then his dick started throbbing. That moment was sooo intense! (If he hadn't been wearing a condom, I always wonder if I could have felt his cum spurting 🤔) 

I wish I could experience that again, but most tops don't hold still at orgasm, so I cannot feel the throbbing.

that is the great feeling when sucking along with the cum spurting that I love a lot.
