Magic lubrication

"Culum Unctum," Willow groaned into Xander's ear. Suddenly Xander felt a trail of warm liquid roll across his scrotum, and with a loud squelch, the head of Tara's cock slid into Willow's anus.

Immediately, Willow clenched her muscles, clamping down on both cocks inside her. Xander grunted at the sudden pressure, but whispered a command. "Relax." Willow loosened up a bit and Tara was able to slowly push her cock in all the way.

Tara moaned, slowly pulling herself back out. "Oh Goddess! It feels so tight around my..." She hesitated.

Willow stepped in, hoarsely shouting "Cock. Call it your 'cock.'" She grunted as Tara quickly pushed back in, and began pumping back and forth. "Your cock... in... my... ugh... ass!"

Every time Tara slammed her cock fully into Willow, the redheaded witch was pushed forward on Xander, her nipples tickling his chest and her cunt sliding up on his cock. When she pulled back, Willow fell back on Xander, his cock buried fully in her wet cunt. Tara's thighs slapped against Willow's ass, and her knees rubbed back and forth against the inside of Xander's thighs. Tara grunted loudly with every thrust, but with the constant see-saw pounding of both Willow's orifices, all she could manage was a steady guttural moaning and short quick breaths.

"Willow," Tara said, "I think I'm going to...going to cum."

Xander was grateful to hear this because he wasn't going to last much longer himself in this position, though some small part of him wondered where the semen was coming from.

"Willow, what should I do?"
