Yes, but its not what you expect

You perk up, feeling abnormally excited at the thought of being released from your cage. "Yes please!" you say enthusiastically from between her toes.

"Yes please... who?" Sam asks sternly.

"Yes please... Mommy." You add on, knowing that she would enjoy it, but also because it feels somewhat natural given your current role.

"Alright" she says, beginning to withdraw her feet from your face. "Go get my strap-on from the drawer." When she said this your ego as well as your masculinity deflated. This isn't what you expected when she said you's get a release.

"Sam..." you begin. "How am I going to get release from that?"

Sam offers you a knowing smile. "Don't pretend that you don't cum from me using my strap-on on you, I know you're embarrassed, but don't be! It's so cute that I can get you to cum without touching your dick. Now go get it and the lube, alright?" She wiggles her foot around slightly, making your key clack against the anklet in a tease.

Defeated, muscle memory you never had before guides you to the right drawer, where you find the phallic object and return it to your girlfriend, who casually slides it on and begins to stroke lube onto it. You feel sick in your stomach, but you physically can't disobey as far as you can tell. Sam lays in a position where you can easily ride her, and stares at you expectantly. "Alright, sit." she says.

You look at the large dick attached to your girlfriend, a lifelike material colored the same as a normal penis, which makes you even more uneasy. It's insertable lengths is easily 8 inches, with a sizable girth. Gulping, you position yourself over Sam, and she helps guide her strap-on to your hole, and Sam puts her hand on your thigh, comforting you as you allow her to penetrate you for what is your first time. It hurts at first, but Sam is gentle, and allows you to stretch and accommodate her before going too deep or too fast. Your cock inside your cage throbs to get out as Sam slowly grinds against your prostate, sending you waves of pleasure you didn't know were possible. You both start to move in rhythmic passion as Sam guides your hips, the both of your grinding into each other, Sam beginning to pant as she gets more excited from dicking you.

You can tell Sam is extremely horny, from her flushed face, her expression, and from her nipples poking against the fabric of her t-shirt. You felt proud that you were pleasing your Mommy, but your mind also recoiled from the idea of calling her that and submitting to her. Sam starts going faster, deeper, as she grips your hips tighter, using your hole and somehow making you enjoy it against your will. She works the strap-on well, gyrating and pushing at all the right times so that she makes you feel as good as possible as she digs around inside your guts.

"Say my name, little one."

You realize you've begun bouncing on her of your own volition as well, your cage flopping around as you say, "Mmm... Mommy... please." Your own facial expression gets twisted, as you feel an unfamiliar feeling building up. It feels like an orgasm, but much different. You try to hide your face, but Sam grabs your wrists. "Let me see your pretty faces, baby."

"Mommy, I... I feel funny." you say, unsure of how to communicate this feelings.

"Shhhh." Sam says. "It's alright, just cum when you want baby. You're allowed to this time, okay? Remember to say thank you."

You continue this act with Sam, bouncing and trying your best not to be aroused by all of this. Same then reaches out and begins fondling your caged dick as you bounce though, which makes you feel much smaller and more ****, as she holds both your manhood and the key which contains it in her possession.

Her soft fingers toying with your caged cock was enough for the feeling to reach it's peak though. "Mommmmmyyyyyyyy... thank youuuuu" You say, trying to sound normal but failing, as your entire body spasms and convulses with your orgasm. You can feel cum leaking out of your cage instead of spurting how it usually does, and your orgasm lasts for much longer. In fact, just as you think it will calm down, you are hit with another wave. "Oh FUCK" you say as you have your first consecutive orgasms from anal. Your dick continues throbbing in the cage and leaking cum until your body calms down, and you are left sitting on Sam's strap-on with a puddle of your own cum on her tummy. "S-sorry..." you say meekly, unsure of what will happen now.
