They say my name

I hear them talk about me. I sit still still covered in my cum i slowly set my feet down and i listen further."This one is bigger than usuals dont you think baby?" Mark says with an uncertainty in his voice. I slowly crawl to my door and i follow the trail of shannons clothes on the hall way floor to her room and i peek in the cracked door. I hear nothing but kissing sounds and the faint sound of clothes hitting the floor for a couple seconds i sit there still as if my movements would activate an alarm, then i see shannon walk in my view fully naked with a strap on around her crotch. It most likely is pegging her as well. Then Shannon whispers something i only faintly hear and it has my name in the sentence. I blush and i see mark bend down and he starts licking the strapon as he looks up at her boobs and face. Shannon smiles and pets his hair i get hot and horny again i start rubbing my flacid cock and i want it to be hard again fast. I watch as mark keeps sucking and taking all the plastic in his mouth then he starts stroking his cock. I look at its size and it couldnt be more than 5 1/2 or 6". I imagine he is sucking my cock instead of her toy. I soon become hard as a diomond and i stroke my member to the speed of his mouth as i sit there in the hallway masterbating. Slide two fingers in my wet pussy i bite my lip and muffle my moans i storke more and more i love master bating in public i think ....well this is kinda public. Mark pulls off her toy and he crawls on the bed sticking his ass out and he says "fuck me with your cock bella" i gasp and i freeze i stop fingering and stroking myself and i sit there i look down at my seaman covered tits and i debate. Is he talking to me? No he is talking to shannon. What should i do?
