Ms T sits next to you and takes your chin in her hand. She looks into your eyes and says somewhat seductive: "I can't even decide what to do first with you. We are going to have so much fun together. Well...at least I will have fun. Oh, don't be scared. I am sure you will learn to love being my slave." These words leave you with a really bad feeling. You look at her, struggling not to look at her nice, firm tits. You know you are completely at her mercy and the last thing to do is to offend her. (She is naked and holds her tits practically in your face, but better not take any risks.) Your math teacher notices your struggle and is now kneeling over you, leaning forward and presenting her breasts. "You like these tits, don't you? Don't be shy, take a good look!" You feel kind of embarrassed and blush a little. Hesitant, you look, even stare at those nice, round tits with these small, rosy nipples. You can't take your eyes off them, as Ms T caresses your chest with her right hand. Her left hand slowly massages her breasts. The sight is awesome and your cock begins to make a move. After a few seconds you are rock hard. Here you are: Tied to a bed, your naked math teacher kneeling over you and your cock is as hard as a rock. Is this situation really as serious as you thought? Now you feel her right hand wandering down your body, behind her back and then gently stroking your left leg. After a few strokes up and down your thigh with just her nails, you feel her moving towards your cock. She grabs it and notices, how hard you are. "Oh, are you enjoying this? I could make you feel really good", she says, giving your cock a few strokes, "but you are not here for your pleasure, but for mine. So you want an A in my class and we still haven't discussed what you can offer me for that." Her hand goes down to your balls and she gives them a small squeeze. "Maybe I take those balls, what do you think?" What did she just say? You can't hide the terror in your eyes, as you look into her face, still kneeling over you with her hand reaching behind her with her right hand. She squeezes tighter and holds her grip firm, causing you to grunt in pain. "If you want me to stop, just say it." "Pweafe fop!" You scream in pain through your gag. "What did you say? I can't understand you." She laughs and tightens her grip even more. Your whole body tenses up and you scream in agony through your gag. "Pweafe don, pfeafe, pfeafe, pfeafe!" Her left hand softly wanders over your forehead. "It's ok. Just relax. I will take care of you from now on." She mocks you, tightening her grip again. You are so tensed up, you can't even scream anymore. Tears and run down your face and you are soaked in sweat. You feel totally helpless, your balls about to crack. "Oh, what a lovely reaction. I knew we would have so much fun together." She laughs while holding you tight in her hand. You are terrified. Will she really crack them or will she show mercy?
