The first month that Robbie wore the "Thimble" was incredibly frustrating...Although Karin was letting him cum about once every three days, the shot-glass shaped metal object now covering his dick was incredibly frustrating...
Part of this was because, of course Robbie was a compulsive masturbator...He'd see some girl with big hair, the kind he'd never have a conversation with, walking down the sidewalk by his firm, or have a few flirtatious words with the legal secretary of one of his partners, and then he'd run off to the firm public restroom, squirt a little pink soap from the sink into his palms.
He'd then dive into the stall, and wank, pausing impatiently as people came in and out of the lavatory, having irritatingly long conversations. Robbie's closet was jammed with porn tapes and empty Astroglide containers...
Now Robbie was horny all the time...he was stupid enough to watch his favorite porn tape "Inspector Fellatio" once with the "Thimble" on, and realized the metal cap wasn't actually big enough to hold his erection...
Robbie had had to shut off the tape and jump in the shower immediately. He now tried not to look at the teenyboppers at the mall, but he couldn't help it. Sometimes Robbie tried to release by humping the "Thimble" against the bed at home...but it was just painful. Karin now had taken to inviting Robbie over more and more to dinner, and she was always wearing something terribly provocative.
Sometimes it was a tiny, clinging shirt, with a push up bra that bulged her cleavage. Now and then she would greet Robbie at the door in some sort of lingerie—a lace teddy or a Merry Widow complete with garters and spike heels. You'd think she wanted to get it on, with all that, but she had locked him into the damn belt!
"B-but why?" Robbie had asked Karin as she'd locked on the chastity belt. "I don't jerk off that much, and I love you." If she really was eager for Robbie to be horny, why the hell wouldn't she let him sleep with her after nearly three years of dating and siz months of engagement?
"Robbie, I just want to know that you're not easing your tensions elsewhere." Karin responded, patting his metal crotch. " When you jerk off and think of some other girl, or even think of me when you're away from me, it's like you're cheating on me... Karin touched Robbie's cheek.
"I know that I am still seeing other men, but I'm so used to regular sex! You've really not slept with that many real-time women, have you sweetie?"
Robbie shook his head, his neck scarlet. Robbie had been so astonished and pleased when Karin had agreed to go out with him the first time, and she was only his second girlfriend in about ten years.
Karin still tied Robbie down once or twice a week and played her "massaging" games on his cock Rub, rub rub, stroke stroke..."This is how I like you, darling, " she'd say, playing her fingers along the underside of Robbie's straining cock, as he moaned and shook, stark naked with the cuffs behind him.
"See, you haven't cum in what is it? Four days? No, I played with you Sunday, but we didn't have time (giggle) for you to come. Six days! You haven't cum, and look at your enthusiasm! It's incredible!"
Robbie's dick was soaked in pre-cum, and it was rather purple that day. His balls were incredibly swollen—sometimes he'd have to go home and ice his testicles after one of their marathon massages...he couldn't rub it on his cock as Karin would've already locked on the belt!
And today, as he rang the doorbell, Robbie was thinking to himself...he'd heard Karin discussing a possible reduction in orgasms...a "behavior modification" program, she called it.
Karin smiled and hugged Robbie as she opened the door for him. . " Oh, baby..have I got a surprise for you!" Oooh.
