I had read stories about guys getting adventurous with watermelons, cutting holes in strategic places. Once in my youth I wanted to try something like that but didn't have a melon. I did, however, have an orange. So after a shower I cut a hole through the fruit from top to bottom and headed into the bedroom with it.
The nice thing about an orange is that it doesn't require lube; the juicy inside does quite well on its own. The pulpy interior felt cool and moist as I slid it up my penis and I was soon working it up and down, trying not to get the juice in my slit for fear that it might sting or, worse, cause an infection. I also wanted to be careful not to get one of the seeds up in there (that would have been an embarrassing trip to the doctor). I stuck to short strokes, keeping my penis head outside the orange and concentrating on sliding and twisting it along my shaft, which felt very nice. Stroking my scrotum with one hand at the same time made it feel even nicer.
The orange I was using proved slightly smaller than I needed, as my energetic humping eventually tore the thick skin apart. Still, I was able to come and finished the episode by eating the evidence. Then it was back into the bathroom to wash off the sticky, juicy, jizzy mess.
But I've always wanted to try the watermelon.....
