True story: I gave sperm samples years ago for a clinical trial. For a month I could only cum during the weekly sperm collection. I was about 20 and used to cumming daily either from jerking or fucking. I would show up so horny. This chubby 30-something nurse measured my balls with a caliper then offered me a selection of porno magazines and a packet of lube. I went behind a curtain and jerked off. It felt amazing to finally get some relief. It was super sexy cumming into a cup for her and presenting her with my load after.
