“This is a cock cage—a chastity device. I plan to lock up your dick so you can’t jerk off.” I was stunned. I almost yelled, “What?!” “...ust sit here and listen. Last night I was talking to Janet about how selfish you’ve been, how you don’t satisfy me in bed, and your masturbation problem.” I blushed. “She told me that her husband had the same problem two years ago, but she solved it with a cock cage. She put it on him for a week the first time. He became very attentive to her needs, but. "I... I, I'm so sorry, I didn't realise anyone was in here..." I managed to stutter out."It's ok, it's my fault." Sonia replied. I felt I should leave, but I couldn't move, the sight was too entrancing.I eventually snapped out of my stupor and began to move to leave."You don't have to..." Sonia trailed off.I turned around, smiling, looking at my feet. When I managed to look into her eyes, I could see the lust as she bit her lower lip. I locked the door once again as Sonia began sliding her. She crossed the short distance to the bed and sat down, her skirt creeping up to show her stocking tops, her tits swaying in front of her, bouncing gently as she walked. My cock quivered in sympathy with the movement; I was as anxious to get it inside her as she was.‘Stand up and face away from me,’ I instructed. ‘I want to take you from behind so I can look at your beautiful bum.'She did as I asked.Much as I had in the shower, I made her bend and support herself on the bed with her arms. Do you know what grinding is Mom? Yes, I know what that is. Well, we did that too. And what did you think? I liked it, a lot. Well youre supposed to. It is the way we are hard wired, you know I discussed that with you before. I just want you to be careful. You know I have told you how sex elicits strong feelings and not just sexual feelings but a connectedness. And also you are both young and inexperienced and with time and getting to know each other things will get better. You tell her you.
