As a young speedo lover would you.......

[Torchwatch]

Speedo sex is foreplay and mutual masturbation while wearing speedos or other brands of swim briefs and bikinis. Oral or digital stimulation may be applied through the fabric of the swimwear or directly to other parts of the body. Speedos are retained for the climax when ejaculate is forcibly strained through the fabric's weave, leaving a visible damp patch.
Although speedos are often used in porn foreplay they are usually removed for the money shot so spoiling the movie for the speedo sex porn fan.
Light colours that go dark when wet (e.g. yellow) are best for this genre.
