Billy's hands came up under her skirt again and palmed her buttocks and partly immobilized her hips while he pressed his lips to her belly. She fought to keep from screaming, looking desperately at Sam, but the look on his face told her to go on, yes, don't stop, she was doing well. Fighting back her sobs, she felt Billy's mouth close electrically on one of her nipples, the lewd sensations shooting from the hardening breast tips down into her womb. His hands came up into her panties from underneath, through the leg holes, to splay across her flexing buttocks, pulling her off balance and hard against him. To steady herself, she closed her hands around the back of his head, causing him to suck so hard that she moaned, burying her face in Billy's bushy hair. Feeling a steadying hand on her shoulder, she looked up and saw Sam standing behind Billy, wearing an encouraging smile. She smiled back, then gasped.

Billy had slid his hand into the cleft of her bottom and was hotly feeling over her anus and down to her vaginal slit. It was already damp from the movement of her dancing and her inner labia were rubbing against her sensitive clitoris. His fingertip had no trouble finding the slippery well of her oozing cunt, sinking in to the first knuckle and doing a quick twisting motion against a tingling, wet spot inside her. Tingles ran up her tailbone, surprising her so that she tried to twist away, but Sam's hand tightened on her shoulder and his mouth formed a silly grin to remind her to keep smiling. She smiled and closed her eyes when she saw Billy's excited eyes staring up at her, and against her will she moved her hips closer to him, forcing his straightened finger entirely up into her juicy, tight vagina. DesirЋe grit her teeth and swiveled her hips around the intruding finger, feeling her lubricant increase as an unwanted pleasure shot through her.
