“Good. Now, you must understand that I own you sexually. You are not allowed sex without my permission. Tommy, do you know what blue balls are?”�...Yes mistress, I do.” I answered.“I’ll bet you have them now don’t you boy? Tell Mistress Shelly the truth!”“Yes ma’am...” I sheepishly admitted.Shelly stood up and gestured for me to do likewise. She said, “Strip! I need to see what kind of boy I own!” I gave Shelly a blank look and hesitated. “Well?” she snapped. I jumped up, saying “Yes,. He'd often flirt with me saying hello sexy, how's my sexy babe doing today etc, making me feel good about myself. Often flirting back with him as well.This particular morning, it was the last week of my 3 month program so while I was busy with my workout, Mark came to watch me, to see if I was doing all the exercise correctly. It was legs and abs day, so I was doing lunges, leg curls, leg raises, crunches, side cruches, leg lifts etc. While doing the leg curls, he placed his hand rather firmly. My eyes stayed on her face, even though I could easily view the tops of her breasts."Trust me," she said, arching her head back up and placing her hand on my leg. "I wish I was a lesbian, Kaylee. I want to want to be a pussy licking lesbo so we could do it, just because I know you want it so bad." Don't worry," I stated before I kissed her. "If it happens, then it'll happen in due time." Okay," she mentioned, leaning up.We eyeballed each other as like hawks. My hand never vacated my panties,. ” The belt tightened around my throat as she began to fuck me, slowly and shallowly at first but increasingly deep and quick as she sensed I was coping. Little words of encouragement like ‘good girl, good bitch,’ urged me on. I knew from her voice she was close and her arousal was even more apparent when she bent and her nipples were hard on my back. A hand went between my legs and began to stroke my clit and invade my cunt. “So wet. If you cum before me I will punish you.” It was obvious she.
