After about our 4th time having sex and me not being able to please my girlfriend, she gave me the ultimatum of no sex, or sex but her way. I chose the latter and ended up taking it up ass most nights to please her and I enjoyed it as well, even though I was stroking myself most of the time.
She loved to experiment with different items, starting with carrots all the way up to a huge 12 inch black lookalike dildo. She fucked me every night for months, until I started to have pain from the strapon sex. I couldn’t get fucked in the ass anymore because of that and soon after she left me. I’d never felt so violated and used before, but also so turned on.
