Undertail Smut #2

"What's that Chara?" Asriel asked Curious about the strange items she brought in. "I brought a strap on and a box of goodies so we could have more fun!" "Strap on? What's that?" "Asriel your just too innocent." Chara said giggling.

"Here let me show you what it is!" Chara said, slipping the strap on up and securing it around her waist. "Oh!" Asriel exclaimed, blushing heavily now realizing how Chara planned to use it. "But I think Frisks already pretty tired out you should wait a little." "What are you talking about Azzy? I'm gonna use this on YOU! So lay back down on your stomach silly." 

"H-huh m-Me?" Asriel exclaimed, pointing at himself the blush on his face now showing even through his white fur. "Yup!" Chara said, wearing a sinister grin. Nervously Asriel lowered himself back onto the bed, his sensitive penis twitching and leaking pre-cum as it touched the sheet and eliciting a soft moan from Asriel. Chara excitedly opened the black box she brought in and produced a small bottle labeled "Xtra Slide Anal Lube'', setting down the bottle on the edge of the bed. Chara firmly grabbed Asriel's ass cheeks and spread them exposing his pink twitching anus.

"Ready?" "I suppose so." Keeping his cheeks open with one hand Chara grabbed the black bottle and popped it open with her teeth. Proceeding to tilt it and squirt a liberal amount directly on his anus causing his whole body to shiver. "C-cold!" Exclaimed Asriel causing Chara to giggle "Sorry! But I'll warm you up real fast here soon!" Closing the lid and tossing the bottle off to the side, Chara took her right thumb and carefully inserted it into Asriel's virgin asshole. Stifling a moan into the bedsheets Asriel cock throbbed harder sandwiched between his soft furry stomach and the silky bed sheets as his bottom was violated more and more by Chara. 

Off to the side of the bed leaning against a wall Frisk sat slowly rubbing her clit as she watched Chara move from a thumb to her pointer finger. Rhythmically Chara penetrated Asriel's ass with her finger each stroke making it go deeper into the depths of his tight untrained goat ass. Smirking to herself Chara knew she had found what she was looking for when Asriel moaned even louder into the bedsheets. Chara's finger had found his prostate and as she pushed deeper inside him she made sure to press against it every time she brought her finger backwards. "I think you're ready for two fingers now Azzy!" Chara excitedly stated taking her finger out and putting it together with her middle finger before sucking on them both.

Chara joyfully watched as she saw Asriel try his best to stay still knowing fully well she had stopped just before he came. After giving him a sufficient amount of time to ensure he wouldn't pop before the main course. Chara traced her fingers down his buttcrack before swiftly thrusting them inside of him. This time Asriel couldn't stifle his moan and let out a large lust filled moan causing even Frisk to smirk. Continuing her rhythmic fingering Chara began to grow tired of the foreplay and quickly pulled her fingers out before crawling atop the bed. She placed her knees on either side of him causing the bed to dip slightly and just as Asriel felt her menacing shadow fall over him she lined up her strap on and thrust into him. 

This time a moan came from both of them though Asriels covered up Charas. This particular strap on featured a silicon piece just underneath the dildo giving its wearer pleasure while they used it. Additionally when Chara thrust the additional push made the piece thrust deep enough inside her to rub against her G spot. Just as with her fingering Chara found a rhythm to her thrusts and each one went deeper into Asriel causing his pleasure to mount higher and higher. While before Asriel tried to hide his moans he now shouted them out and gripped the bedsheet as hard as he could.

Finally as they both neared the summit of sexual ecstasy Chara made one more deep thrust before leaning over and biting Asriel's shoulder hard but not hard enough to draw blood. Causing them both to reach the peak at the same time and orgasm together. Fluids flowed past Charas strap on as she shivered all over and Asriel came forcibly plastering the bed sheets and his stomach with semen. After panting for a while with Chara laying on top of Asriel, Chara pulled out of him and flopped to the side with Asriel eventually doing the same. "Did you *gasp* like it?" Chara asked, obviously out of breath. "Y-Yeah I liked it alot... Thanks guys."
