There’s a fine line between..... I really get off on the pleasure/pain of having my nipples pinched and played with hard by my wife, while I’m throbbing in my cage. Recently I suggested to her that she use her fingernails when she’s playing with my balls. Wow, that’s whole new sensation, my sharp intake of breath as she scrapes her nails across my sack, then squeezes hard and holds, has told her that like the nipple play, this is something that gets quite a reaction from me. At the start of 2021 I said I’d like her to push my limits this year in our play. I’ve been locked up 24/7 for 28 days now, which is a new record for us. I think she’s taken my suggestion on board. BCWYWF. But damn, I love my wife.
