Hiccup sucks Astrid's cock.

Hiccup pulls her blanket over her body.

"Astrid, what's going on?" Hiccup asked.

Astrid did not answer. She suddenly found the latches that held her skirt together and undid them, letting the skirt fall to the floor, revealing the torn open front revealing her erect cock. Suddenly, Astrid grabbed Hiccup's head and shoved her cock into Hiccup's mouth.

Hiccup grabbed Astrid's thighs, trying to get the cock out of her mouth but failed, Astrid being much stronger than the boy-turned-dickgirl. Hiccup nearly choked as Astrid **** her cock into her mouth faster and deeper, hiccup feeling the head hit the back of her throat. Astrid, now under the lust-based madness, found no shame in her actions as she made various moaning sounds and shouting obscenities like "fuck" and "oh yeah" and "take it, take it, TAKE IT!"

It did not take her very long before she buried herself as far into Hiccup's throat as she could as cum rushed from the shaft deep into Hiccup's throat. As her orgasm ceased, she unsheathed her half-erect cock and fell back, regaining her breath. Hiccup leaned over the side of her bed, coughing violently, the oral **** rough on her throat.

"What...what happened?" Asked Astrid, regaining her senses.

"It *cough* it happened again," said Hiccup, her throat horse and syrupy from the semen coating her throat.

"Oh gods," said Astrid, as she laid back on her back and placed her hands over her blushing face.

"Okay," as Hiccup started, briefly coughing some more before continuing. "This is becoming a problem."

"What are we supposed to do?"

"I don't know. We'll need to figure out when these... um... 'spells', I guess, start to manifest. If we can't stop what is going on, maybe we can find a schedule. I don't know about you but I don't want to end up like this with other people around."
