The first thing John felt as he started to regain conciousness was a pleasant buzzing sensation emanating from his crotch. He felt full - no, he felt filled up. His mind was hazy, his perception dull. He tried to focus on what he was feeling. There was something inside him, vibrating gently. Something filling up both his ass and his... pussy. Yes. He was in Jennifers body, now, he realized. There was a weight on his chest, hair tickling his shoulders. He could feel a chilly draft running over his smooth skin, across his erect nipples, and a little shudder went through his body. He was, he realized, naked. The pleasant warmth in his crotch was inviting, and he slid a hand down to play with himself. It met thick leather.
John opened his eyes. As he sat up, he felt the tick leather strap running between his legs, denying him access. Locking the vibrating toys inside him. He was wearing a chastity belt. He looked down, and saw that it was locked with electronic locks. The kind he had used several times on Jennifer. The kind that could be programmed to only unlock if certain conditions were met.
A blinking light in the corner of his eye told him he had an unread message in his PSI implant. He mentally willed it to open, and a video of Jennifer appeared on his retina. Naked except for the chastity belt.
"Hello, John, and welcome to my body. You've probably noticed my little welcoming present. I thought I should help you get in the mood, get acquainted with your new body and urges." John knew that getting accustomed to the feelings of a new body could take some time, but the quicker it was focused on after a swap, the easier it would come. Jennifer obviously wanted to drive her sexuality into him. "You're wearing my chastity belt. You know it well, I am sure. Two vibrating dildos. One in your pussy, one in your butt, the anal one inflatable, and a clitoral stimulator with electro-shock capabilities. Programmed to not give you release. You're going to have fun." She gesticulated and pointed as she said all this, smiling gleefully.
"I've programmed the locks to disengage by ten. By then, you're probably going to be so horny, the first thing you'll do is masturbate yourself to exhaustion thinking of what I'm going to do to you tomorrow. Have fun." The image of Jennifer blew John a kiss before disappearing. John looked at the clock. Twenty minutes to eight. Almost two and a half hours of gentle stimulation.
The clitoral vibrator suddenly went into full gear. John squealed out loud. "Or not so gentle," he thought. What had he gotten himself into? Over three days in the body of his petite, horny girlfriend, with all her submissive urges. He would be humiliated, degraded, fucked, his holes used for Jennifers pleasure. And he would enjoy it. The mere thought of it made the warmth in his crotch spread, sent shivers of fear and excitement up his spine.
The dildo in his ass started to inflate. It triggered something inside Johns mind. The situation he was in now fed directly into Jennifers humiliation fetish. Not having any control over how her holes would be used. He could feel his excitement growing, his crotch getting wetter by the second, but knew the chastity device would not allow him to come. It would keep him on the edge for the next two hours. "Fuck me," he thought. Well, at least it would be an interesting weekend.
