Her mouth around my cock.

As she closes the door behind us, I feel my little friend rising to attention. Her body really is enticing. My eyes stop at her face and I decide she wouldn't mind being a doll and tending to me a while.

She looks at me just as she is about to enter the bathtub. Sighing, she lets her foot fall back to the floor and says, "Bro. Are you fantasizing about fucking me up the ass right now while I have my boobs swinging beneath me or something?" She rolls her eyes. "I gotta give you a blowjob. That'll get rid of your distractions, at least while I shower in front of you."

I don't argue with that. She approaches me and grabs my zipper, pulling it down. Then she rolls my pants to my feet and tugs my briefs down. For the first time ever, she has her face deliberately next to my hard penis. Also for the first time ever, she grabs it and begins stroking it with her moist hand, feeling my length with her balled palm as she bounced my testicles with a finger.

Suck it, I think to myself. She proceeds to stick the dick into her mouth and roll her tongue around its head and girth. I grunt, attacked by the pleasure of both her ministrations and the unbelievable way in which I am getting what I want. I wish for my orgasm to be strong and pleasurable.

A few moments later, my dick stiffens even more rigidly. Jessica is pushing her face all the way to my pelvis, and once I feel her throat surrounding my penis I remove her gag reflex. She is able to take it in with gusto, and I sense an impending climax.

"Mmmmhmhgjmmmhg!"

My sister gurgles and coughs after I take my dick out from her mouth. It begins to grow flaccid, thick strings of sperm stretching from its tip to her lip, and then I wish for it to remain as hard and large as ever. It twitches back into life, a proud boner, and accidentally slaps Jessica in the cheek. She is still coughing and swallowing, even standing up. She begins to wipe the residue from her mouth with a tissue, until she decides it would be better to just swathe her fingers through it and lick them dry with her tongue.

"How was it sis?" I ask, making her give me a positive response.

A twinkle enters her eyes. "Bro," she smiles, licking her finger clean of the final wallop of her brother's semen. "That was the best moment of the entire year!" Giggling, she turns, bends forward, and slaps her ass cheeks back and forth for a while. Then she grinds it against my penis, wiggling it into my pelvis, and pops forward once more. "Love ya bro," she says with a wink, turning back to the bathtub. "Anyways, I gotta shower now. You're still going to watch me right?" She gives me a knowing look. "You should be free of distractions now anyway."

I stroke my chin at my still naked sister, now situated under the shower head as she begins to turn it on, and consider the notion, one of many now possible.
