A/N: A wee bit steamier than the last few! Enjoy!
Marceline could hear Bonni's heart pound furiously in her ears; the din a rhythm of nerves and anticipation, excitement and pleasure. She swallowed loudly, and tried to force the sound from her head, tried to concentrate on the girl who owned the heart, the girl who was nose to nose with her now, the girl whose eyes were lidded lazily as she drew closer.
The sound made Marcy hungry. The lips drawing nearer made Marcy a different sort of hungry, a hunger she wasn't used to feeling. A slow, churning knot twisted in the bottom of her stomach, tightening with each moment Bonni's face hovered inches from her own, tightening at the sight of Bonni's soft, deliciously pink lips, so close… So close.
Marceline was pleased to close the gap swiftly, feeling the soft press of Bonni's mouth against hers, but found her hunger unsatisfied. They parted briefly and she saw Bonni grin before leaning back into her again. The girl's heart was pounding so hard, so loud, that Marcy could hear nothing else, not even her own thoughts. Bonni grated her teeth over Marcy's bottom lip, Marcy's fangs meeting them with a click, and she felt her stomach roil with desire. She let out a small sound, a "mm," which caused Bonni to tilt her head with a light laugh and pleased grin.
Marcy's brow scrunched with slight irritation. Vengeance came to mind as she took her opportunity to nibble gently down Bonni's jawline, careful not to catch the soft skin with her too sharp fangs. Marceline didn't have to hear Bonni's pleased mumble, laugh, and sigh over the drumming noise; She could feel the vibrations against her lips through Bonni's throat as she trailed her nips down. She paused at the spot where Bonni's neckline met her shoulder, nipped a little harder, tasting the sweet skin there against her tongue, and felt Bonni make the same "mm" noise that she herself had made moments ago. It was followed quickly by a word that came from her lips as though it was her favorite flavor, "Marceline."
The vampire's mind emptied; she snapped her eyes shut. Her nerves were drawn taut, ready to splinter. An ache grew in her chest, seeped into her stomach, and she couldn't tell which the greater desire was. Bonni pulled Marceline tight against her as Marcy persistently kissed and nipped at the same area. Bonni's knee slipped, pressed, right between Marcy's thighs, and Marcy… Marcy—
"Ow!"
Marceline pulled away, red-faced, ashamed, and—
"You bit me…"
All fumbling apologies, Marceline made to push Bonni away, to a safer distance, but Bonni kept her locked in an embrace. The vampire twisted away, or tried to, but the princess held fast and she was laughing. Laughing! Marcy stopped struggling, swallowed thickly, the embarrassment wedged in her throat, and looked down at the princess who was reaching up to press her hands against Marcy's temples.
The laughter faded into a fond smile. "Hey," Bonni said gently, sensitively, sliding her fingers gently down to cradle Marceline's face, "It's okay."
Marcy looked away and chewed at her own lip. She felt hot with humiliation that she couldn't control herself, couldn't separate the desires. "Sorry," she said quietly, unable to meet Bonni's eyes. "Sorry, I-… I won't do it agai-"
A short firm, "No," cut her off and the gentle caress of Bonni's hands became firm to bring their noses closer. A second "No," was softer and the smile that was gone for the first crept sneakily back onto Bonni's lips. The cadence of her heart picked up again in Marcy's ears, but Marcy was focused solely on Bonni's next words. "I meant…" She looked away, seemingly unable to meet Marceline's eyes now, a rosier color seeping into her pink cheeks. Pulling the vampire's head down further, Bonni whispered in Marceline's ear with impish confidence, "I liked it."
