Sensory deprivation when completely immobilized is kinda like an extreme form of meditation. Kinda. Being inside a leather rest sack with belts pulling tight across your body and other straps keeping you harnessed both sides can be a relaxing way to spend an afternoon. But, another layer of relaxation is added to that when you involve a nipple dome machine and you have a beautiful mistress touching your dick. Yes, a perfectly relaxing morning, evening or afternoon.
