I was 18 when I moved in with Ruth. Ruth was my new land lady, I moved in with her for my university studies time frame. She had a big house and leased a room.
Ruth was 56, in great shape, she was about 170 cm tall and about 50 kg with small breasts and a very nice figure.
I was very excited to move, I loved the idea of sharing a house with a woman. I imagined myself peeking into the shower or her room to see her naked or taking her panties from the laundry basket for masturbating. All those thoughts got me very aroused, my cock was hard as I arranged my stuff in the room.
I had not cum in two weeks. My parents were always around in the last two weeks so I could not jerk off, but now, I have my own room, I am so horny, I can finally jerk off.
I opened my lap top, looked for a Jerk Off Instructions clip, got naked and started jerking off. The girl in the clip was so hot. She touched herself, made jerking moves on a virtual cock, it was so sexy. After about 10 minutes I exploded, the cum burst out and landed on my chest and belly.
Ruth entered my room the moment I came, she just opened the door wide just as I shot my cum, she saw everything. Her reaction was furious...
"Young man, what is this? Are you watching porn and jerking off in my house?" She demanded. "This is a behavior I can not allow, I will need to make sure it never happens again!"
She left the door open and went away to her room.
I was so scared and so aroused, my hard-on would not go away. She returned 5 minutes later and saw me.
"Still hard?" She questioned. "This is not good. Jerk it off and get it soft. Do it now young man, we have no time."
I was so embarrassed and surprised, I could not get soft. I was naked in the same room with a very sexy and very strong woman. I was aroused like I'd never been in my life.
"What are you waiting for? Jerk it off, get it soft!" She ordered, impatient.
I obeyed her instantly. I started to stroke myself in front of her, her firm gaze assessing my every move, watching me. It took me 5 minutes to cum again, but I still wasn't soft. I needed to keep going and cum a third time to complete the task I'd been given.
Once I was finally soft, she pulled out a metal chastity cage. Ruth came close to me, she lubed my cock and balls with the lotion I'd been using to jerk off, this was the first time a woman ever touched my cock and balls. I was getting hard again, but she was fast enough to cage me before my cock could stiffen. And there it was, I was locked in a chastity cage.
The next month was very difficult. Ruth completely ignored the incident, nothing was said. We just behaved as if all was normal. As if nothing had happened. Not a single word about jerking, sex, getting caught or chastity. I had never been this horny in my life, and so helpless. I could not get hard, could not jerk off and definitely could not cum, my balls were so full and so sensitive.
Then, one Saturday morning, at 10 AM Ruth called me into her bedroom. She was wearing tight jeans and a white tight T-shirt, she looked very sexy.
"Strip." She ordered.
I stared for a moment, still shocked that she'd acknowledged me at all.
"Get naked." She snapped, more forceful this time. "Sit on the armchair."
I obeyed immediately.
She told me to put my hands behind the chair and not move them and to put my legs apart on the arms of the chair. It was like sitting in a gynecologist chair. She took the key out and unlocked my cock. I got hard immediately. She started jerking me, but did not touch my cock head, only the shaft. She made sure I would not cum right away, it was obvious she was very experienced. My hips could not stop moving. I was so eager to cum, I started moaning. She kept me right on the edge of cumming.
Then she stopped.
"You need to make a choice." She said. "You can get a full satisfying orgasm from my hands. I will make you cum like you never have in your life. But then you will need to be locked for 3 months... I could give you a ruined orgasm. All that stored cum will be freed. But there will be no sexual satisfaction in this orgasm and you will be locked for another month... Or you can get the full orgasm like in the first option but you must eat all the cum that you ejaculate. Every drop of it. You will then get to cum again after one week. But you need to keep in mind that if you take the third option it means that you agree to eat your cum every time you cum from now on. No way out of this agreement."
I wasn't able to think, all I wanted to do was explode. I just moaned and fucked the air with my hips so she made the choice for me. I got my first ruined orgasm. It was so frustrating, I felt no pleasure, the cum just burst out and I felt nothing. I started crying and begging Ruth to let me cum, she just sat there waiting for me to get soft and locked me back up.
The following month was hell for me. I was horny and frustrated, I cried a lot. I knew what was going to happen when she called me to her room again.
The month passed and the moment I feared arrived.
I was on the chair in her room, in the gynecologist position just like in the previous month. Ruth took the chastity cage off and very gently masturbated me. She massaged my balls, worked my shaft, teasing me to the point that my moans were almost screams. Then came the three choice question.
