Yes and yes

"Alright. That's enough." The words come not a moment too soon and your girlfriend actually sobs with relief when you withdraw the vibrator. Her hips continue to twitch and her vulva pulsates for several seconds, which you can see very well, but hopefully is not visible on the camera.

"Thank-you, sir," Diana pants, breathing deeply as her heartrate gradually returns to normal.

"Now swap over."

You obey with a sense of fear. Despite what everyone has been telling you today, you would like to think your self control is reasonably good, but given your current state of arousal, enduring so much stimulation without climaxing seems close to impossible. Nevertheless, you have no option but to try, so you lie back and concentrate on cabbages.

The large vibrator slides inside you quite effortlessly and immediately starts to rotate. The effects are instantaneous and profound. You have always found this particular sex toy highly efficient at bringing you to orgasm, but tonight it seems to be working better than ever. All attempts to distract yourself with thoughts of vegetables are blasted from your head by the deep pounding that your girlfriend is required to give and you moan with lust as the pleasure threatens to overwhelm you. Without needing to be told, your fingers instinctively travel to your turgid nipples and start rolling and pulling them.

You edge quickly, your toes curling into the duvet. Knowing the futility of asking for respite, you can only whimper as the earthshattering orgasm inches closer and closer. Your body is quivering, throbbing with need and you are about to surrender to the inevitable, when your landlord speaks.

"Stop."

Diana jerks the vibrator from your sex and you moan, whether in disappointment or relief you are not sure yourself. Your ordeal seemed much shorter than your girlfriend's and at first you put this down to the time flies while you're having fun effect, but then George Collins says one more word.

"Go."

The process starts once again. Being fucked to the brink of orgasm until you can't stand any more, then an all too brief respite, followed by another tortuous edge. One thing you have to give to Mr. Collins: he really seems to be able to read your arousal well, not calling a halt until the last possible moment, but never letting you go over the edge. You lose count of the edges almost straight away, but the maddening cycle goes on and on, with no end in sight. At some point, you realize you are sobbing with frustration, but that does nothing to help.

When the end comes, there is no warning. George Collins says it's enough and your girlfriend turns off the vibrator with a sigh of relief, but you are nearly delirious with denial and passion and Diana has to shake you and tell you to stop playing with your nipples before you realize it is over. You slump on the bed, the tension is your muscles from fighting off your orgasm finally allowed to dissipate.

"Thank-you, sir," you say, when you can eventually speak. You are genuinely grateful that he did not **** you to climax, just so he could punish you. However, that gratitude is short lived when he tells you what comes next.
