I used a silicon rubber (the kind girls use to attach hair in the shower). Tension is ajustable by elongation, so it is easy to wrap around balls without sliding.
It gives an outstanding shiny look to the tensed balls skin, and pressure boosts pleasure arousal...
Hi there, married gal here. I'm mid 50's. I'd love to suck your cock in front of my husband. He loves to watch me suck other men. I'm sure you would enjoy my wet mouth. I would love to feel you shoot a huge load in my mouth to swallow. And when I suck you I am all yours. I'll swallow every drop of your hot cum baby oh yeah. I suck slow and long to build me up a real big load. Would you be interested? My name is Sandy. Let me know okay? Bye now.
