Madeline Lets Lawrence Cum in her Ass for Extra Caps

Madeline looked back at Lawrence. He was on the edge of cumming and she knew she had the chance to probably get out of him whatever she wanted. Putting on a seductive smile and cocking her head to one side she made Lawrence and offer.

"If you give me all your coins and a bit extra I will let you finish in my ass." she proffered him with a wicked look. Lawrence stopped thrusting, pulling his cock completely out of her.

"Wait what?" Lawrence said questioningly.

"You can finish in my ass if you give me the whole collection and some stuff to barter."

"Hmmmmmmm" he considered the offer suspiciously. Madeline leaned forward and stuck her ass up, pulling one hand on her ass cheek to reveal her tight asshole. Lawrence starred, looking at her tight hole, it was immaculate. The laser dare had proven very efficient.

"Not even Norman got to do this." Madeline lied, goading Lawrence's pride. She knew that they were in competition. And her and Norman had only done it a few times.

"Okay." he said "I haven't tried this before." He said almost blushing.

"Not even with Angela?" Madeline said with a sly smirk, remarking on the real Vault Slut who had probably slept with every guy in their age range (and probably all their fathers too).

"Ha ha." Lawrence said mockingly.

"Just start slow." Madeline said, moving her ass closer to his cock. She new that with anal sex lubrication was needed, luckily her own fluids acted as a lubricant. While she wasn't a squirtter Madeline always produced enough wetness when having sex. When she orgasimed, even more so.

Lawrence moved his cock to her tight hole with ease, Madeline still held her left cheek to give him a good view. This was for both their benefits. She didn't want him poking and prodding aimlessly again. Slowly, holding his cock steady with one hand he moved his head to her orifice and pushed slowly forward. Madeline went rigid as she felt him enter her. It had been a while since she had done this and she winched slightly in pain.

He halted his cock at her cry and when she nodded for him to continue he continued going inside of her ever so slowly. Madeline's pussy had been tight, but Lawrence felt her ass cling to his cock tighter than anything he had felt before. He took it slow, moving deeper inside her.

"Uhhhhhhhh..." Madeline moaned softly as Lawrence put more of his manhood inside her.

"UGH! UUUUUHHGHHhhhhh!" She moaned as she felt him put more than half of his shaft deeper.

"AH!GUHHHHHHHHHHGGGGGGGGGH!!!" Madeline nearly yelled with a mix of pleasure and pain.

"Fuckkk." Lawrence said as he pushed all the way inside of her, his balls hanging down against her wet slit.

"Oghhhhhgggghhhhhh MhmmmmmmmmmMMMMMMMMMM" Madeline tried to subdue her voice as he moved inside her.

"Goddddd Uhhhhh Yesss." Lawrence groaned.

*tic tic tic* a sudden rasp on the metal room door came, causing Madeline to seize up slightly sending a ting of excitement through Lawrence.

"Lawrence?" Mrs. Copeland muffled voice came through the metal door continued "Is everything okay?" If Madeline wasn't looking directly at the door and could see his face it was red as an apple.

"Yes! Mom!" Lawrence yelled "Its fine! We are okay!" His cock was still inside Madeline and fortunately the metal door was locked, but even Madeline could tell that his cock had lost some stiffness from the sudden fear of being discovered.

"Okay. I'll leave you be." the motherly voice said "Oh Lawrence I made some tea, make sure you tell Madeline."

Madeline had to bite her hand to stifle a laugh.

"Oh my god." Lawrence said still rigid from fear.

"That was close he he he." Madeline laughed.

"Uuuugh not funny." Lawrence said beginning to move his cock again. It came back fully to life with ease. The excitement maybe even added to his pleasure as he began a slow rhythm.

"Just keep it down." He said as he thrust forward.

"Don't UGH! Worry I wil--UGH!" She got cut off by his sudden thrust all the way inside of her, Lawrence's balls slapped against her.

"You are ah so GAH fucking ggggggh! Tight!" he said through clenched teeth. He was back in the groove and while he did not thrust with the same speed or power as he had in her pussy they were still measured and constant. He gave her ass a spank and held her ass cheek as brought her ass back toward his shaft. After a half dozen thrusts Madeline braced herself with one hand and moved her other hand down underneath her reaching her hands out for Lawrence's balls. She spread her dainty fingers and found his scrotum, cupping them gently she squeezed softly.

"AhhhhhhhhhHhHHHHH AHHHHHHHHHHHH! UUUUUUUUUUUUUUUUUUuuH!" Lawrence almost yelled as he began to cum. Madeline's stimulation of his balls was just too much, even with sudden fear of his mother's disturbance had not been enough to dampen his spirits. Her touch made him cum with a ferocity he hadn't enjoyed in a good while. And as his cock became super sensitive as he came the reality of how tight Madeline's ass really became intensified.

"oooooooooooooooOOOOOOOOOOH!" Madeline moaned as she felt him climax.

Madeline felt his load fill her ass, it was warm and gave her a weird sensation as he thrust forward in a final motion. Even as he was still inside her she felt his cum trickle out of her asshole. He was in such intense pleasure--almost pain from the pressure of her ass on his cock that he couldn't even conjure words but made an animalistic moan as she slumped over. This only drove him deeper inside of her, and thus made his sensations even more **** as her ass tight end giving natural resistance. With a spasm, his toes curled in his shoes as Madeline huffed out a moan at the final gyration.

"OGH!" she let out a yelp.

Slowly Lawrence steadied himself and stood up, slowly moving his cock out of her he saw the mess he had made.

His cock was covered in cum and as he pulled his cock out completely a wave of his warm goo surged out of her ass. It trickled down her taint and skirted the lips of her slit, sliding down following the curvature of her inner thigh. Madeline sat up and looked back at Lawrence with a wry smile which turned to a grimace when she felt her movement send out a second gush of goo.

Lawrence looked down at his handiwork with a grin.

"Well Maddie," he said looking around the room for a towel "I think you will be very very good at bartering up there."

"I am sure I will be fine." She said, sitting there on all fours motioning at her ass as if asking for a rag or towel. Lawrence looked around and returned with two towels.

"If you keep using your...." he paused for dramatic effect as he handed her a towel "_ASSets _I am sure it will all work out."

Madeline rolled her eyes as she cleaned her thigh with the rag, wiping up the goo.

"Very clever." she chided playfully.

Lawrence cleaned himself with the other towel then retrieved the coin collection and placed it on the bed. Then he went and grabbed an extra stash of gold Eagle dollars Madeline didn't even know he had.

"It was all very much worth it." Lawrence said taking in Madeline's sensual body one last time as she zipped up her vault suit."

"I'm glad you think so." Madeline said as she took her hard earned coins. "Remember don't tell anyone about this."

"Of course!" he lied, knowing full well he would tell all the guys--especially Norman.

Slowly she headed out of the room door, to get a nice hot shower. While she didn't want to go through all this trouble, she figured it would be well worth it if it meant surviving the wastelands easier.
