"Erza.. what are-"
The rest of Lucy's sentence was cut off when the scarlet-haired mage's lips were linked with her own. Lucy pushed Erza off of her long enough to stutter out,
"E-Er-Erza! This i-isn't a good id-idea!"
Erza responded to this by pinning Lucy down, once again, and resuming where she left off.
The blonde's lips were still parted slightly from protest, and Erza used that as a chance to deepen the kiss. Despite her earlier statement, Lucy moaned silently at the intrusion. She could no longer deny herself what she so selfishly craved. She kissed back, sharing a deep kiss with Erza, their tongues dancing playfully together. When they pulled apart briefly for some much needed air, the key mage flipped the situation (literally), picking up Erza and pinning her on the bed.
Lucy held Erza's wrists above her head with one hand, while using the other to explore her friend's goddess-like body. She slowly slid her hand up Erza's shirt, quickly finding what she wanted. She gently squeezed the large breasts of the girl under her, just hard enough to make her moan. Getting the reaction she aimed for, she continued her play. She gingerly pinched Erza's nipple between her thumb and index finger, and then began massaging it with her thumb. Erza's back arched slightly while she stifled another moan. Lucy frowned and leaned in close to whisper in the red head's ear.
"That's no fun Er-za-chan, I want to hear you screaming."
The said mage's face flushed bright red, but soon became occupied with her lips and Lucy's. Lucy licked Erza's bottom lip teasingly, asking for entrance. Erza parted her lips, and both girls' tongues were flicking and swirling against one another's. They let their hands begin to wander, exploring every dip and curve of the others body. Clothing was lost. Then hands traveled lower, turning things into complete bliss. It felt like ecstasy in their veins, exploding like fireworks. Every touch, and every thrust of their fingers, brought even more pleasure, and neither girl could have enough of it. They were thrusting their hips, grinding against and with one another, and moaning wildly.
"A-ah!
Er-za, I'm.. *huff* about to.."
"Mnnm, me.. *pant* too."
In no time, both girls reached their limit, yelling the others name through one last moan. The rest of the day, and through the night, they lay there as a knot of tangled limbs.
"Erza?"
"Shh..," whispered young Titania, while pressing a finger to Lucy's lips. With that, they both drifted into a peaceful and (for once) un-disturbed sleep, holding one another.
