After sex shame has never been a problem for me, until now. I just fucked AJ; The sex was great, but I can’t believe I did it. We’ve lived together since we were 10, as close to actual siblings as you can get. I can’t get over how embarrassing this would be if people found out. I can’t even look in the mirror as I wipe his cum off my face. I have never been one to love the taste of semen, but his tastes wonderful. AJ walked out within seconds of his orgasm. I wonder if he is feeling a bit shameful as well. I fucking hope he does. I shouldn’t be the only person feeling like a brother fucking slut.
My phone is ringing for the second time in the past 5 minutes. People should know by now that I don’t answer my phone; just send me a text. I’ve never been a phone talker. I hear AJ stomping down the stairs; when he reaches my room, I know he is not happy. I can’t help but admire his body as he stands in the doorway. His muscles are glistening with sweat. I could easily fuck him again right now, but that’s not a thought an average person has. Fuck, what is going on with my brain.
“I’ve been calling you Cait. You need to start answering your phone.”
“Umm ya..that’s a girlfriend thing, and I’m not your girlfriend…just your ‘sex slave,' get it right” I hid my shame with a little sass. AJ walks over to me in just his towel and releases it within inches of my body. He is like a magnet right now, I can physical feel my body pulling itself to him.
“Why are you dressed? You’re filthy. Let’s take a bath” He almost looks sad as he heads to my full-sized bathroom. I am giving myself a few seconds to breathe before facing him again. As he is starting the water, he lights my tea candles and adds in a few bath oils. I can’t say I’m not confused. It’s like he is romancing me. There is nothing romantic about being a sex slave. I undress while making my way to the bath, he has already made himself comfortable. I go to sit on the opposite side of the large tub, but he motions for me to get on his lap.
Feeling his thighs in between my own is making me want to ride him into tomorrow. His cock is already rubbing at my entrance. It’s not quite hard, but it’s significant enough to be noticed. He pulls my face down to meet his lips. The stubble his has tickles my cheeks, I can’t help but to giggle.
“What’s so funny?” He asks with a smile.
“Your stubble tickles, you should probably shave soon.” I laugh again. I am starting to feel so relaxed around him. We haven’t laughed like this since we were children. I lean down into him and kiss him. Kissing his lips feels so right but it's quickly moving into much more. I have never made love before; I just fuck. I’m not sure what he is going for, but he is really pushing my sexual boundaries. I don’t do romantic; I need to fuck him.
I lift my hips to lower myself onto his length. He slows me down “No Cait, we’re going to take this slow.” He softly kisses my shoulders, so gentle that they’re giving me goosebumps. The way is cock leisurely explores my opening is so different, yet sensual. Soft sex is a first for me. I quietly moan into his ear with each push of his cock.
“Baby, tell me you want me. I need to hear it” He whispers, I refuse to give him that. “AJ, I said already, I’ll never tell you that. This is strictly a deal.” I can tell He doesn’t like that “Fine.” Is all he has to say. He roughly pushes me up and down on his thickness. Now this is what I’m used to, fucking. He was pushing something that wasn’t me. He needs to understand that I only agree to be a sex slave, not his girlfriend. My orgasm is building when he tells me to get out and lay on the bed. He seems a little agitated, so I do what he says without sass.
He slithers in between my legs; Instead of entering me, he pushes my knees to my chest. “You’ve done anal, right?” I nod my head. Little by little he inserts a finger into my ass, working it to be able to fit his manhood. He adds another member until he has three pumping in and out of my tight hole. “Lube.” He demands. I point at my desk, not able to talk through my pleasure. I stare at his firm ass while he walks away, I wish I could tell him how badly I want him right now. I can’t let go of my pride right now, I’ve already given him everything else.
I am still holding my legs up to my chest when he returns. AJ is pumping the lube over his cock, I can feel myself getting wetter just watching him. He places his cock at the edge of my hole, stretching it inch by inch. I love the way he bites his lip when he pushes deep into my begging ass. I can’t hold my pleasure any longer as my hole pulses around his hardness. “Oh fuck Cait” he moans as his eyes meet mine. I feel his warm seed fill my rump. I bring my legs down around his waist as we heard a car door shut outside.
“Oh shit,” I whisper. They aren’t supposed to be home until next week. I still have the mattress in the living room, and I’m fucking my step-brother. I’m sure that would be the final straw for them. Heck, AJ would probably be just as screwed.
“It’s okay Cait; I’ll work it out. Now clean up.” He grabs a robe out of my room and leaves.
I don’t know how he will work this out, but I trust him. As weird as that sounds.
