Often when I needed space on the clothes line, I would take my housemate's clothes down and folded them into the basket. I would usually take an extra minute or two to inspect the impression of the bulge in his jocks and have a sniff. As they were freshly washed they would mostly smell of soap, and be warm from the sun, but would also retain some of his masculine scent.
In the early days of our cohabitatation, he told me that he was not into stuff with other guys, but he knew I had a crush on him. He was always appreciative when I took his washing down, and I don't think he would have minded that I held his sunwarmed jocks to my cheek for a few seconds...such a sweet guy!
