Sally & Emily's Bedtime #12 (Commission) (Pixiv Fanbox)
Content
Emily closed her eyes, lost in the pleasure that her little sister was giving to her. Her dainty little tongue flitted incessantly over little love button, sending wave after wave of electric love through her body. She was getting close... Her voice squeaked as her body began to convulse to Sally's licking. Looking down at her sister, their eyes met and that was the final tether to be broked as Emily had a massive whole body orgasm. The shaking started at her feet and moved up as the burning white light of her orgasm overtook her. Vision, smell, sight all faded away into the feel of her pussy being eaten out. She quaked and shivered...until right in the middle she had a horrible realization...as to why she'd gotten out of bed in the first place.
Her bladder was completely full.
She struggled to hold it in...but it was too much to fight against the orgasm wracking her body. She weakly lifted herself up as her body voided the urine that she'd be holding in this whole time. "I'm so sorry, baby" she whispered to her sister underneath her as the torrent spewed onto Sally's face. But instead of disgust and horror...Sally seemed almost excited...blissful. Her mouth opened and she greedily drank up the fluid filling her mouth. It filled her and splashed all over her cheeks and onto the bed below.
The two girls stared into each other's eyes in amazement. This was the start of Sally's new love of watersports.
