I work at home several days a week. On the days when I'm feeling horny, I play this all-day pleasure game.
My favorite vibrator, the Hitachi Magic Wand, is kept lying on the bed, plugged in, and 'ready to go'. The first session begins around 8 or 9 am. I walk into the bedroom and hold the vibrator against my cock. I first hold it up at the base until I feel a response, and then slide it down and hold it against my cock head. I wear snug jeans, so my cock becomes stiff, but the heavy cotton jeans prevent an erection. I'm standing while doing this.
Holding the vibrator against my cock head causes my arousal to slowly build. At least it's slow during the first half of the day when I'm not so aroused. I keep the vibrator working on my cock head until I'm ready to cum, then I turn it off. It's both a big let down, as well as an emotional high, to stop just at the point of orgasm. It takes a few moments to regain my equilibrium, shift gears, and get back to work.
This scene repeats at least once an hour, sometimes as much as every 15 minutes, throughout the day until evening. I'm very aroused by the second half of the day, and little works gets done by late afternoon since sex and orgasm have pushed all other thoughts out of my mind. It also doesn't take long with the vibrator against my cock head to bring myself to the point of orgasm during the late afternoon sessions since I'm so ready to cum.
When I can't stand the teasing anymore I strip, pour some lube into a condom and slip it over my now free, erect, and very sensitive cock. Stroking my cock, contained within the lubed condom, feels like it's inside of a pussy. The day-long teasing has produced the right amount of physical and mental stimulation, so leaning against a wall and slowly stroking is unbelievably erotic and pleasurable.
Orgasm is literally explosive, both in the amount and intensity of ejaculate, and in the muscle spasms - and verbal noises! - that accompany it. My knees are weak, so I need to sit on the edge of the bed while I recover.
A very fun way to spend a day working at home.
