I used to have a top that used to push a pair of briefs in a plastic bag through my door he'd loaded up for me. I never knew when he was going to do it. He used to do it about every 5 or 6 weeks. He liked me to send him a video of me sniffing them and send him txts telling him how much I loved the smell of his spunk. I'm married now so haven't been able to receive anything like that but now it's possible to send an item to a parcel locker so I could collect it safely and discreetly.
If anyone's interested I would load up a cumrag for you and send it to you if you'd do the same for me, sending it to a locker for me to collect. I can do the same, or straight to your home address if you prefer that.
