After our first Goddess Weight Training session, I found that my sub was incredibly hard. Taking my weight, knowing I was training him for more of it - got him so incredibly turned on he just couldn't help himself. So I decided to use him like the human furniture he is, and grind on him, teasing him with my bare ass. I could feel his hard cock under me, aching to be inside me - but that's not something I would allow. I wanted him to feel what it was like being under me while I rode him, but not get the chance to actually fuck me the way he wanted. So he had to lie there fully clothed, hands tied with me covering his mouth with my hand to make it hard to breath - all while I bounced and ground my bare naked, incredibly large fat ass over his cock.
