Groped in the Park Until You Cum in Your Shorts

You didn't even see it coming. One shove and you're face-first against the park wall, my hand at the back of your neck, shorts still on while I slide my lubed fingers underneath. I press inside you, curl against your prostate, make you whimper and shake...all while people pass close enough to catch us. You're panting, dripping, trying to stay quiet... until I add a second finger and milk you into your briefs. I wipe my hand on your underwear, clean myself with a wet wipe, and leave you sticky, embarrassed, and mine.
