You're not the only one well-endowed

She rolls her eyes as she starts to move her hand back and forth before he looks down at your crotch and gawks. "What… what the fuck… this isn’t real right your cock can’t really be…" Grace's voice trails off as she realizes what she just said. She shakes before grabbing on to your huge cock, the heat and the size of that thing made her want you even more. In due time, your sister begins to stroke it up and down, biting her lips at every moment she can get.

"Well I'll let you find out... if you let me have my way with those tits of yours..." You say with a grin, already knowing you've got your sister right where you want her to be. Pausing the video of a compilation of Black Widow bouncing her breasts inside that slutty outfit of hers, you begin to watch as your sister falls in love with your massive beast of a cock.

Grace continues to stroke, watching it go up and down as it oozes a bit of pre-cum on to her fingertips. Despite still being inside your pants, the dent it made only made it hard for her to look away. “Fuck…” she slowly kneels and brings up an arm to compare to your bulge. "So i guess we have a deal then."

She nods slowly too focused on the smell of your cock. The sweet, musky aroma fill her nostrils causing her to want nothing more than to have that thing inside of her. “Uh… yeah sure fine, whatever. Just take it out now!” She says as she bites her lips.

"Damn I didn't know you wanted to see it this badly..."You respond rather teasingly, slowly lowering your pants as each passing second showing a small part of the huge beast hidden. Going as slowly as possible to tease your slutty sister, you finally decide to succumb last minute. Finally after a couple of seconds, your cock springs out from your trouser and instantly upon making contact, slaps Grace on her face.

She begins to blush, feeling the heat of your cock all around her face. When your dick flops its tip, it instantly hits her lips and flings pre-cum across her face. “Holy shit… it’s so big… how?”

"What can I say... guess I wasn't the only one blessed with something big." You say with a smirk, watching as her nipples start to harden just from being around your musky cock.

Grace begins to stroke it, now feeling the full thing without the help of rubber. Her slim hands barely able to wrap itself around your entire shaft together. “Fuck… how is this attached to you?!” She says in a day dream, her hands picking up speed as she bites her lips. Saliva starts to form from out of her lips as she begins to imagine all the things she could do with it.
