You always give 110%

It's hard to be stuck-up when you've already got a load of cum leaking out of your ass. Besides, your mom always told you to give to the homeless. You don't think she had a big smelly uncircumsized bum's cock in mind when she said it, but you can't pick and choose when it comes to charity.

"I'm going to give you a treat!" You smile at the old bum and jerk down your pyjama bottoms.

"Ahm," he says, dumbfounded, "Ahm...s'okay, you don't haveta!"

"I insist!" You reply cheerily and thrust your ass towards his face as you yank down your thong.

Without missing a beat you turn and stand over his jerking cock, its filthy length pointing straight up between your legs. You reach down as you lower yourself into a squatting position. The smell is nearly enough to make you gag, but you're not backing out now. You actually sort of want his big dick crammed in your tight little cunt.

You wrap your hands around his prick and stroke it a few times before you lower your pussy over its head. The tip slides in easily enough, but both you and the bum groan as you ease all the way down until you're sitting on him.

You close your eyes and try to imagine someone that doesn't attrack flies. You lower your hands to his chest and begin to rock your hips back and forth, grinding down on his big cock.

"Ah," the bum groans,"thas amazingk. You're sho tight."

Almost immediately, rough hands grab your big tits through your shirt. A moment later he's pulling and stretching the fabric aside and roughly yanking your bra down to your stomach. You let him, lifting up and down and moaning quietly as his dick glides in and out of your now sopping pussy.

The bum's wirey beard rubs against your bare tits and he begins to tug and suck on your little pink nipples. Despite the stink and his rough handling, his big cock feels amazing buried in your pussy. Each time you rock down its length you can feel it probing the deepest parts of your lovehole.

You pick up your pace as a climax begins to build within the depths of your pussy. You almost never cum this way, without rubbing your clit at least a little, but despite all odds it seems this bum is going to get you off. You can tell he's getting ready to unload as well. His cock is throbbing and so big and hard you can almost feel his heartbeat inside your clenching cunny.

Suddenly, you hear a sound behind you...
