Crystal

You realized you had recently been avoiding your sister and decided this would be the perfect chance to spend some quality time with her.

As you went to your sisters room to let her know you made her decision you could hear her talking to somebody on her phone through the walls. “Of course I’m bringing him who else? Nope he’s still a virgin and don’t worry I have the perfect costume for him to wear! Actually I think I hear him outside my door now.”

You really began to regret your decision and tried to run away. But your sister had opened her door and snatched you up bridal style before tossing you into her room and locking the door. She had always been very dominant and forward with you ever since you were kids, but today was different. It seemed like she was tired of waiting and was ready to take what she wants

You opened your mouth to speak but Crystal pounced on you and covered your mouth with her hand. “Shhh shhh shhh. We don’t need Mom and Sarah to hear us. Now I’m going to get you ready and then I’ll show you our costumes.” She explained giddily like a kid who’d just been promised their favorite toy.

You wondered what crystal meant by get ready before she tore off your pants and threw you on the bed. She grabbed a chastity cage and a butt plug and began to stride towards you. “Crystal what the fu-.” Was all you could get out before she jumped onto your head and sat on your face. “I told you to be quiet Dougie. Trust me you’ll be glad I did this. Your protests were muffled by your sisters ass which practically enveloped your entire face with how thick it was, with her testicles practically the size of your cheeks perched right onto your mouth preventing any sound.

You began to protest as you felt Crystal begin to lock the chastity cage on before hearing a faint click from underneath your sisters ass and the tightening of your cock. You began to struggle as you knew what was happening next. Crystal pulled your legs to her giving her a perfect view of your virgin hole.”Trust me Dougie you’re going to be so glad I did this. I even got the plug monogrammed just for you! Though I’m not going to tell you what it says. You’ll have to hope somebody else tells you.”

You wondered what your sister meant by hope somebody else tells you and realized Crystal was going to show you off to people right before she spat on the plug and on your tight asshole, lubing them up properly before promptly shoving the plug up your ass. You emitted a mix between a squeal and a moan that surely would have been heard from everybody in the house had she not been sitting on your face

“Now I’m going to let you up now and show you our costumes. If you struggle and refuse to wear it I’ll just tie you and gag you and then make you wear it. Mom won’t care in fact she’ll just think it’s funny and take more pictures. Now get up” you complied with your sisters orders, grateful for the chance to finally breathe before you saw the costumes Crystal brought out.
