"I'm gonna blow!"
"Neville! It's only been two minutes!"
"Oh fuuuuck!"
Luna had been bouncing her little bald pussy on Neville's cock for only a few short moments before she made him start cumming. She slipped off his pulsating dick and lowered herself between his legs, amused by his panicked moaning. His face red and breathing heavily, Luna slammed her fist into his large droopy balls. As the boy yelled out in pain, Luna closed her eyes, thrust her face forwards with her mouth open, and allowed Neville's huge cum load to paint her pale face. "Lunaaaa!" The first warm rope of cum splattered across her eyes and forehead, the second across her nose and the third went straight into her mouth. The last few drops just dripped out his cock and Luna collected it in her hands. She kept it inside her mouth and rolled her tongue around, then stood up, her hands soaked.
As he finally finished cumming, Luna slapped Neville across the face, wiping his cheek with his own cum. "I'm sorry Luna, it feels too good, I couldn't hold it in." He apologised, ashamed of himself but it was nothing new. He had never been able to have sex with Luna for more than five minutes. Luna knew he would cum prematurely, but she still enjoyed the brief sex and humiliating him afterwards. "I can't really blame you. My tiny little pussy is extraordinarily tight." she said with a giggle, licking a bit of cum off her finger. "But since you can't hold your cum in, I won't be able to hold in what I've got, either." she said, smirking and moving closer. "What is it?" Neville said, almost breathless. "My disgusting diarrhoea!" She yelled out suddenly, before turning around and planting her plump arsecheeks on his lap. "No! No!" he tried to protest, but weak from his orgasm he couldn't move.
"Here it fucking comes!" Luna said, inhaling. "Gonna shit!" she gave one last warning before releasing her bowels. Neville groaned deeply, looking down at his still hard cock and her bum. At first she just let out a few squeaky farts, but as she lifted herself, a flood of watery shit squirted out in a huge burst. The relief made her moan aloud. "There's more!" she said sharply, pushing out with all her strength. More diarrhoea poured out of her arsehole, watery with large lumps in. It felt so warm on Neville's lap he couldn't help but groan in pleasure as his cock and balls were soaked. A few more watery farts slipped out, before another wave of shit poured out, her arsehole making disgusting noises as it did. Neville couldn't help himself, and even though he just came, he grabbed his cock with his right hand and began wanking, mixing in Luna's horrible watery shits.
She felt that her bowels were empty, and turned around to admire her work. She didn't expect to see Neville wanking, and slapped his hand away. "Please let me!" Neville said in protest, his messy cock twitching. "No, I need fucked!" Was the blonde girls reply as she straddled the boy, almost slipping off due to the watery shit. "I need my cunt fucked!" She gathered up as much lumps of shit as she could and smothered his cock with them, then pushed it into her sopping wet pussy. It slipped in with ease thanks to the diarrhoea, and they both let out deep moans as it went all the way in. Neville grabbed her skinny hips to hold her in place as she bounced on his lap, making bits of shit flicker off everywhere. "My shit feels wonderful inside me! I feel so full up!" She said dreamily, her head thrashed back, dribbling. After three minutes of bouncing, the pair were both sweating.
"I'm getting all sweaty!" Luna said, moaning between each word. She raised her arms up to observe her arm pits and tried licking one. "Luna! Your armpits! They're h-hairy!" Neville said, panting. He never expected to see a patch of blonde hair. "I'm growing them! Just keep pounding me!" She said, moaning like a whore as a shit covered dick ploughed into her womb. She then used her right hand to rub her left armpit, smothering her sweat all over the hair. Again she tried to lick herself but the angle was too awkward, so she leaned forward and shoved her hair smelly armpit into Neville's face. Immediately he began to lick and suck the hair and Luna began to shake. Neville's moans had increased, as had Lunas. Having her armpit eaten felt wonderful. "Keep licking my smelly armpit!" She said as she bounced, her small tits wobbling. Knowing she was close, she held her sweat covered hand up to her nose and inhaled. The result was instant. Her pussy clenched making Neville yell out in pleasure. "MY STINKY ARMPIT SMELLS SO GOOD!" She screamed, and as she shoved as many sweaty fingers into her mouth as she could, she began to cum. Her pussy started to vibrate and that set Neville off. "They do! Fuck, Luna, your sweaty pits are making me cum!" He warned as his second orgasm built up. "I'm cumming too!" she squealed, and together, covered in sweat and shit, they shared an orgasm. Neville filled Luna's small womb up with as much cum as he could.
Moments later when all had calmed down, she realised something. Neville had just impregnated her.
