Handjob from behind

After offering her reward, she didn't wait for me to respond. With a coy smile, she sexily strutted behind me, taking exaggerated steps, making her hips and ass rock side-to-side. Once behind me, she pressed her body up against mine, her big, round tits pressing into the middle of my back. Alison seems so immediately overcome with a desire to please me that she reached both of her hands around my waist and pushed her pelvis into my backside, as though she was going to hump me, grinding and moaning softly as she did.

"I don't want to mess my outfit or makeup before I leave, but that doesn't mean I can't stroke this big cock before I go" Alison said as she slid her hand inside my waistband and gripped my stiffening cock. I was hoping for a blowjob or sex, but this was better than nothing.

"I like the way you think. Let me help you get it out then." I replied, unbuttoning and unzipping my pants, allowing Alison to hoist my long, thick cock from its cage. The eroticism of the moment had me fully erect almost instantly. Alison's tiny hands looked comically small around my dick's girth, her fingers barely able to wrap themselves around it completely. She brought her other hand to my cock as well to try to even the odds between my massive member and her slight paws, but even her double fisting covered only about a 1/3 of its imposing presence.

"God, I will NEVER get used to how BIG you are!" Alison uttered with a mix of shock and sensuality, as she began to slowly work both her hands up and down the long distance of my cock, her arms at the extremes of their reach trying to surpass the tip. You release a satisfied grunt as she strokes, intermittently sighing with delight, reveling in the size disparity between your cock and her petite grip.
