I apply for a suspiciously well-paid “virgin clinical trial” and arrive at what looks like an ordinary hospital, relieved to see other adult volunteers there. Then, on the female doctor’s orders, the nurses suddenly start giving us blowjobs to collect our semen. After I choose my favorite nurse for a smoother examination, she kisses me, licks my nipples, gives me a handjob to measure my erect cock, and edges me with a masturbation sleeve to test its pressure. For the eagerly awaited ejaculation-distance test, I slide my bare cock into her and shoot a huge load from the overwhelming pleasure of my first time. Right afterward she asks, “May we also test your semen during a creampie?” With a first sexual experience this filthy, how will ordinary sex ever measure up?
