I've availed of CIM a few times, and usually I don't try the "mad-dash method" you described, where you wait until you're already cumming (or mere seconds away from it). I'd had a girlfriend that would occasionally let me do facials or CIM with her, and you really need to time it perfectly if you do it that way!
But with escorts, typically what I've done is go until I'm close, but not too close-- say maybe 30 seconds to a minute from cumming-- and switch back to receiving oral from the lady until 'blast-off'! Never had a professional swallow, only had that with a few girlfriends way back...
i have been offered cim a few times but i never went for it not my cup of tea at all it wouldn't interest me i am old fashion guy well i am 80 you know
Oh you mean the place with the golden gates. Great. I mean have a think about it. You spend your whole life trying to have fun and not feel guilty, trying not to have fun and feeling guilty. You get a bang and drop someday and wake up outside a pair of fuckin gates. :-)
