"What are you doing Step-bro?"

"Why not?" He gave a quizzical look. "Come on… How much porn have you seen with this same kind of stuff? Besides, you can just say that I was extra kinky. Wouldn't that be better for your dickhead friends?" He pondered for a moment seeming to weigh up the options all the while I was just rubbing my thighs together feeling the wetness between my legs grow. Jason finally responded with a quick nod before aiming the camera back at me. I immediately let out a giggle before popping the head back into my mouth and swirling my tongue around it to coax him towards an orgasm. "God, you're so big step-bro." I felt his cock throb in my hands saying it. Looks like he may be enjoying this new taboo as much as I am. "I hope Mom and Dad don't find out about us." Somehow his cock gets even harder than it already is. I keep working the shaft with my tiny hands using my spit from the tip to coat his cock and let me slide up and down with ease.

I take him further and further into my moist mouth, savoring the texture until he reaches the back of my throat and I gag. I withdraw for a moment without letting him fully leave my lips before pushing back down again. This time I am able to take him just a bit further but as soon as he reaches the entrance to my throat I start gagging once again. I have to take a second to breathe as tears have started to form in my eyes. "It's harder than it looks." I place his cock back on my face and feel the heat and weight along with my own saliva covering it. "Especially when it's so. Fucking. Huge. Step-bro." Each one of my words is accompanied by this meat stick whacking against my spit-smeared face. God, I must look like a mess, but we've got to keep going. And my mouth is already starting to feel empty without Jason nestled inside it. I start going at this cock with everything I've got. I can't seem to deepthroat so I focus on his sensitive head running my tongue along and the underside and begin to grope his heavy sack while planting kisses up the shaft. If only I could spare a hand to tease my nipples or give the inferno going on downstairs some relief but all of my attention is focused on the wonderful cock in front of me. That's when I start to feel it. His shaft seems to grow and harden and his ball begin to tense. He's about to cum. Jason lets out a grunt and looks down at me "I'm gonna cum sis." Okay, got to make the finale good. I guess it's now or never. I look him dead in the eye straight past the camera and say "Cum in your sister you sick fuck." Before slamming my face down and pushing his cock into my esophagus through sheer ****. I feel myself start to gag violently again but this only causes my throat to squeeze down on Jason's cock over and over again finally sending him over the edge. It's as if a fire hose went off in my throat and a torrent of cum shoots out and down into my stomach. Starting to feel light-headed I withdraw the large intruder from my airway in order to get some much-needed oxygen but Jason still hasn't stopped cumming yet. I try to gulp it down but spurt after spurt quickly overwhelm me and flood my mouth until I'm **** to pull it out entirely. But he's still got more in him as the last few sprays cover my face and glue one of my eyes shut until the gigantic load is finally over. I look up at him through my one available eye and see him breathing heavily with his head back while still having his phone pointed squarely at me. Trying to be as sexy as possible I open my mouth to show off the pool of jizz inside, swirling it around and gargling it before swallowing it. Unfortunately, it's a lot thicker and sticky than I'm expecting which catches me off guard and I begin to cough. While some of it made it to my stomach the rest is sent flying back up however I am able to close my mouth in time to stop it coming out. This leaves only one other place to go as my coughing fit has jizz dangling out of my nose. Jason has regained enough focus to be paying attention to the show as I gather up all of the remaining cum plastering my pretty face before giving his tip one final suck and swallow the rest without incident. "That was so yummy Step-bro. Promise you won't show anyone this, right?" I figured that those guys would like the video more if they knew it wasn't meant for them. Jason just gives an exhausted nod before his head falls back again.

"You're the best Step-bro!" I give his cock one final smooch before getting up and leaving the room. God that was amazing! I can feel his spunk sloshing around in my stomach all the while the heat between my legs is now a dull throbbing along with a visible wet stain on my yoga pants. Even after cleaning my face is still feels sticky as well as the wet patch between my thighs and the overall sheen of sweat over my entire body. I think I need a shower.
