My Introduction to Bisexuality, Part II

It turned out that Jim and Melissa were planning my surprise for quite some time, ever since Mellisa first told Jim about how she spanked me. He confessed that he loved to have a helpless guy lying naked over his knee while he spanked the guy's ass to a deep crimson. Melissa was unsure how I would take the surprise, but they began planning anyway. I was soon to learn what else they had planned for me.
After my first spanking over Jim's knee, and the subsequent blow job, we repeated this scene every weekend evening for the next five weeks. It became clear that Missy was just very turned on seeing me disciplined and sexually dominated by another man. The sixth week was a little different. It was a Saturday evening when Jim showed up at our door, and I was expecting our usual routine, me over his knee for a long and severe hairbrushing, and then me on my knees giving him a blowjob. As he finished punishing me Missy announced that I've teased Jim long enough with my mouth, and it was time to let him have my ass. By this time, I was so completely submissive to them both that I quickly hopped off Jim's lap and bent over the edge of the bed. Jim wasted no time plunging his throbbing cock deep into my ass, and quickly began pounding away. He fucked me for a good fifteen minutes, stopping only to fuck my mouth for a few minutes too. He returned to work on my ass and soon had an explosive orgasm while deep inside me. Missy grabbed a small saucer and ordered me to push his cum out onto the plate, and then ordered me to lap up every drop. As always, I quickly obeyed. To make matters worse, after Jim left I got another hard spanking from Melissa for being such a slut. My ass was redder than its ever been, and it still hurts to think about it,
but that's still not the end of the story.
