Your doctor requires a semen sample but you're struggling to produce it. The receptionist gave you some materials but you're not able to achieve ejaculation. That's ok, the situation can feel a bit awkward... but maybe nurse Leela can help. I ask a few questions, observe your technique and once I've determined that nothing is wrong I decide to try to see if I can't help to stimulate you. I lift up my scrubs and show you my big breasts in a lovely lacey bra... It's not enough though, is it? I pull back my hair and strap on some PPE - a surgical mask, and latex gloves and I ask to stimulate you. You enjoy the feel of my gloves against your skin, and my hands wrapped around your cock. With just a little encouragement and assistance I get the sample needed and collect it from off of my glove.
