Doug is curious

Doug waits for her to go to sleep, and stretches out to the wall and licks the cum. But is unsatisfied as it has already mixed with the paint. Testing his luck, he reaches down and scoops some cum from the thick deflated cock between his legs. The taste makes him horny enough that he feels dizzy. He repeatedly reaches down to caress the thick meat, and can feel it starting to grow. At first he rubs his thighs against it, but than gets an idea. He moves upwards, and places the glans against his own ass cheeks.

The glans feels wet from the grease and the cum. Doug caresses it, feeling the growth spreading his ass cheeks apart. He is consciously terrified of the size, but he cannot stop.

In her sleep, Lin shuffles a bit pushing a bit harder against you. Her quiet snore encourages you and you try spreading your asscheeks with your hands even more. Mid sleep, Lin helps you, in a reflex motion. The tip of the monster is now at your gate, you are fanatically rubbing against it to get some of it inside. To your frustration, you cannot even budge it.

"Mhmm.. what. Oh. I really should have expected this. Dougy, I promised your sister." Lin says stirring from her sleep.

"Please Lin, I want to feel it. Just the tip. Please." Doug could hear the word come from his mouth, as if through a dream.

"Oh well, It's your fault if your sister asks. I just cannot refuse a cutie like you especially when you sound so ****." Lin says, and starts pushing a little harder. Doug now starts feeling the pain, it shoots through his entire body, sending alarms of something unnatural happening.

"Shhh.. Dougy, Shh..." Lin says, after a small painful moan escaped Dougy.

Doug can feel something large gaining ground inside of him, at the same time something squirts inside of his opening soothing the pain. That must be Lin's precum.

"Now, we need to wait a little." Lin says, stopping the pushing and rotating her hips.

"M..M..More." Doug can hear himself say through gritted teeth, as his body starts pushing back towards the monster.

"Oh.. You really are a good little slut. I like you more with each minute." Lin says and continues pushing, this tie even harder. The pain shoots through Doug's entire body, his back arcs and his skin erupts in goosebumps as the large corona of the glans starts making it's way. At the same time a wave of numbing pleasure washes over Doug making him even more dizzy. Doug begins bucking more wildly against the fat tip at his gate, powerless to move, his body rocking like a fish on dry land.

"Please.. Please.. More. Fuck me Lin. Please fuck me." Doug could hear his voice plead through the haze of pain and arousal.

"I don't know Doug. I haven't gone this far on the first time in a long time." Lin says, traces of doubt in her voice. But the effect of Doug's lust is taking a toll on her. Even as she says this she continues pushing hard.

"Bit on this" She fumbles for Doug's wallet on the night stand and showed it into his mouth. And then she gets a good grip on Doug's hips and with a powerful push clears the corona through, sinking several inches of cock meat along.

Doug is shaken by an unearthly wave of pain and pleasure. He cums, his cock spasming into the darkness of the room, his entire skin is in goosebumps, and his entire body spasms violently. Meanwhile, the wave of pleasure washing over him, rolls his eyes back and he starts mumbling incoherently. Lin bits her lower lip, feeling another orgasm coming on from seeing her effect on Doug. She starts slowly pumping into Doug, an inch back, an inch and a half forward, slowly making her way down. Doug's pwn orgasm never subsides, he just continues dry cumming.

Soon Lin's own orgasm comes along, being her third orgasm this evening makes it slightly smaller than the ones before, but it is still sufficient to fill Doug, making a small indentation in his belly.

That's when Doug passed out.
