Trial And Error
Padma wiggled irrately and hissed at her twin, "Come on!"
Parvati clambered awkwardly onto the bed and settled down next to her sister, long dark hair swinging loose over her face. "Are you sure we should be doing this?"
"Yes. We were each other's first kiss, so why not this?"
Parvati nodded slowly. "Yeah, I guess."
Padma grinned quickly, and tugged her sister down on top of her for a kiss. "It'll be fine. I mean, what could go wrong?"
"Mhm."
"Ow!" Parvati swiped at her sister's shoulder sharply and grimanced. "What the hell are you doing? Trying to bite it off?"
Padma looked up from where she lay sprawled half across Parvati's chest, one hand cupping a breast. "Oops, sorry. I'll be careful with my teeth next time."
"You better. That fucking hurt!"
Padma rolled over abruptly and glared at her sister. "Well, fine. You try it then, see if you can bloody well do it better."
With a muffled sigh Parvati sat up and waited for her sister to move over before leaning over her in the same sort of position. Bending her head, she gently lapped and sucked the other girl's nipple into his her mouth. Padma's hands drifted to her shoulders and she groaned quietly. "Ohhhhh."
Parvati lifted her head and smiled, "See?" before being pushed back down by Padma's hands.
There was a muffled thump and Parvati slapped a hand over her eyes. Padma lay in a heap on the floor next to the bed, cursing loudly, one hand clasped to her jaw. "My jaw. What happened?"
Parvati looked sheepish and rolled over to give her twin a hand back up. "Um, heh. You did something with your tongue and um, I twisted. And jerked up. Sorry."
Padma curled up on the bed and clutched her jaw. "When I said 'what could go wrong' I didn't mean for it to actually happen. Ow." Parvati leaned over and kissed her sister gently. "I'm sorry. Maybe next time it'll go better."
"Hopefully. I mean, it didn't go too badly this time, did it?" said Padma, staring into her twin's eyes.
Parvati grinned. "I guess not."
