I'm easy either way. If I know I'm seeing a red hot babe with great feedback, I'll go for the hour. If I'm unsure, I'll go for 30 minutes. Either way, I only ever go for one pop.
There's also something gloriously sleazy about a quickie 15 minute cock suck session. Knock on the door, enter, hand over the cash, drop your trousers, get a good 10 minutes of OWO, spunk down her throat, wet wipe, pull up kegs and leave.
The lack of communication makes for an anonymous nature to the session that I quite enjoy. It's also the reason I like £40 15 minute glory hole sessions.
Anyone think the same?
