Becky wants to fill you up with cum

By: Cheese111

You look up to your sister looming over you, a wicked smile on her face and a rock-hard cock jutting out from her loins. Big Willy was still eager to play and you had no strength left to stop him. With some effort she hoisted you back onto your feet. Your legs felt like jelly, but Kim happily offered some assistance in propping you up. Her thick cock entering your ass made almost no sound this time. The abused hole was still stretched wide by Becky, only just beginning to recover from her nearly man-sized monstrosity invading it.

"Oh no, you've gotten all loose. Becky, if this stays permanent I will be a little upset with you." Kim said jokingly. You'd be fine and by tomorrow your ass would probably be tight enough to give Big Willy the experience he'd be looking for. Not that your sister had too much trouble with it right now. She was still thrusting and moaning like it was going out of style.

Worse yet, the frequent push and pull around your backdoor was stimulating your groin and soon enough your cock began to rise. Your whole body felt wracked and abused but somehow there was still enough vigor left for an erection of all things. Becky was quick to notice it too.

"I knew you loved this as much as I did. Here's your reward, little Willy." She adjusted herself, hovering the tip of her huge shaft right in front of your manhood. "Cum inside my cock. I know you want to." She teased. Your girlfriend couldn't be further from the truth. After feeling that fleshy pillar rearrange your insides you couldn't get far away enough from it. But your movement was pretty much entirely directed by Kim, who eagerly bumped you forward, fucking you in the ass whilst making Becky's desires come true.

The squeezing, slimy embrace of Becky's cock all around your own was disgusting and arousing in equal measure. You still couldn't shake the feeling of Keith and Anthony being swallowed whole by it. What would their world be like now? Swimming around in your girlfriend's oversized balls? You shudder at the thought. As much as you didn't want to give her the satisfaction, Becky's cock was milking yours in ways that touched your primal instincts directly. You were completely out of control as you felt yourself climax, spurting a meager volume into the colossal shaft of your girlfriend.

"Attaboi, I knew you still had some spunk left in you. But now you're looking a bit drained... Maybe I should return the favor." Your eyes went wide with fear. Was she about to **** her next orgasm into your cock?
