My other half’s boy wrote up a fun fantasy before his trip out to Chicago for training. He gave me permission to share it here. It’s mighty sexy.
—————–

You lead me into the playroom and tell me to strip and stand before you to be inspected. You then apply lube by rubbing it on my upper chest first, testing the sensitivity of my nipples. Your hands then slide down my abs to my crotch. You flick the chastity and chuckle as I wince against my growing erection. You then instruct me to turn around while you apply lube to my shoulders, down my back, and onto my butt. Your hand then inspects my crack and you slide your hand up and down stimulating my hole making me groan.

You then hand me the rubber singlet and instruct me to put it on and to unzip the crotch so that the chastity was hanging out. As Im putting the rubber on you go to retrieve a few items from the closet. Upon your return you have me kneel in front of you with my head down. You ask me if I have missed you as you place a gloved hand beneath my chin and raise it up for me to answer you. I tell you that I have been unhappy while I have been away from you Sir.

You then stroke my face with your gloves and press my face into your crotch. I begin to nibble gently your boner through your pants all the while trying to withstand the pain starting to radiate from my own confined erection.

You start to raise you hand, lifting my chin up, signifying that I should stand. You lead me to the bench and have me lay down. You strap me down first my legs, then you tightly secure my waist, making sure that my chastity is not trapped between my body and the bench, and last you secure my arms and hands. You walk around to my front and dangle my collar in front of my face before locking it around my neck. You then unzip your pants and remove your hard cock letting it bounce up and down in front of my face. Your gloved hands start to stroke my face and you ask me if I deserve to suck Sir’s cock. I tell you that I would do anything to make you happy.

You then tease me by rubbing your cock across my face, slapping it into my forehead and sliding it across my lips, letting me feel your precum flowing out. You place on gloved hand beneath my chin and throat and the other behind my head. I begin to open my mouth and you tell me that I will not suck until you tell me to. You slowly enter my mouth with your rock hard cock. As you do this you firmly hold the back of my head and slightly massage my throat muscles. You keep pushing until you hit the back of my throat and you are firmly pressing my head into your crotch. You continue to hold it there until I begin to gag and gasp for breath. You tell me that I was a good boy but I still cannot suck on your cock. You continue holding my head and throat as you slowly fuck my face in and out occasionally forcing yoruself all the way in until I gag then pulling it back out. Sometimes wiping your cock across my face. For the last few minutes you allow my to intermittently suck your dick and then you would fuck my face. You withdraw your cock and wave it in my face asking me if I enjoyed it. I tell you that nothing made me happier than to let you use me for whatever you wish.

You then move away and then return with a muzzle which you attach and lock to my head. You ask if it feels loose and make sure that its a tight but comfortable as possible. No need for it to be loose for your boy. You then attach a leather lead to the back of the muzzle and move towards by ass.

You smack my rubbered ass a few times to show me what it is you want to do next. You slowly unzip the rubber. You then place one gloved finger on top of my hole telling me that this is Sir’s and will be used when and how he likes it. You lube up your finger and slowly insert it into my ass, then two fingers. You slowly finger fuck me in and out, rotating your fingers to loosen my ass muscles. You then suddenly remove your fingers making me feel empty. I then feel your dick head against my hole. You tell me that I need to relax as you stroke my lower back making me more comfortable. You slowly push into my tight hole. Enjoying every inch as you insert your rock hard cock all the way to the base. I groan from the feeling of being filled, of missing you while I have been away.

You begin to slowly fuck me in and out making sure that my ass muscles are good and relaxed before settling into a pattern of rapid fucking followed by deep thrusts. You grab onto the leash attached to the muzzle and tell me that after fucking me you are gonna bring your puppy to bed for a nap but at the moment I am your rubber fuck toy designed only to pleasing Sir. Your thrusts become harder and faster until you finally explode within my ass. You release the leash but remain with your hard cock within my ass. You tell me that I have been a good pup. You slowly remove your cock but then replace it with your fingers to make sure I am still loose. I then feel a hard cold surface as you begin to push something into my ass. You tell me that I am receiving my tail and to try to be as loose as possible. It takes a little bit but you finally force the pup tail into my ass.

You finish up by zipping the rubber singlet back up and giving my ass a few slaps. I wag my tail for you which brings a smile to my face. You then proceed to going about releasing me from the bench before leading me by the leash to the bed where we lay down together to have a puppy nap.
