"Let's go to your bedroom Jen, we can't leave you like this," Claire said. She took Jen's hand and the two girls hurried to the bed, knowing what would happen without sharing a word. As soon as they got there, they feverishly removed each other's remaining clothes and began kissing, Jen's erection swelling between them.
Claire laid on her back and spread her legs slightly, her wet pussy glistening. Jen crawled up to her on the bed, directing her sensitive cock and pressing its head against the wet entrance. Claire's pussy took her in almost hungrily, loosened by the excitation. An electric rush ran through Jen's donkey cock and she felt the head swell more and more inside Claire, who started moaning. The sensation was unlike and of them had experienced before.
Jen began thrusting back and forth, panting loudly as the rising feeling she had experienced before was slowly coming back. Her donkey balls were churning and pulling tightly against her body, as she looked at Claire's blissful expression. Claire's breasts were rolling on her chest in rythm with Jen's thrusting.
Claire's insides suddendly clenched as she hit climax first, tightening around Jen's cock and sending her friend over the edge. A gush of cum spilled into her inside and overflew a bit, surprising Jen who unvoluntarily withdrew and started shooting another rope of cum on Claire's belly and the bed.
"Oh no! I'm sorry!" Jen whimpered between two moans of pleasure, while Claire was still trying to catch her breath.
"It's fine! I'm just... I..."
Claire's voiced trailed off. A spasm ran through her body and settled in her clit. She did not know it, but Jen had activated the second part of the curse by having sex with her.
"Something's happening Jen, I..." Claire started, before getting hit by another strong spasm and squirming on the bed.
Jen looked down, Claire's cum-leaking pussing slowly closing. The lips were swelling visibly, getting round and covered in soft hairs. Her glistening clit hood thickened in irregular growth spurts, then started lengthening as well. As Claire sat on the bed and looked down, her gaze met with a plump sheath-like appendage and round orbs very reminiscent of a donkey's.
Jen's immediately remembered back of Kyle's words, but then her train of thoughts trailed off. It was a part of the curse that neither of them would attempt to remove the curse, and when Jen tried to focus on the subject, her brain would just switch to something else. Claire seemed equally confused for a second and opened her mouth to say something, only to close it again.
"I'm sorry Claire, I didn't mean for things to turn out like that. I'm not sure what to do now..." Jen said, rubbing her head a little.
"What do you mean?" Claire said, tilting her head. "I don't understand what it is you want to do... Some things just can't be helped. We just need to keep this a secret from everybody else."
Jen's eyes were a little wet with emotion. She didn't know what to say. Claire leaned forward and hugged her friend tight, the fluids smearing around on their bellies and breasts. Claire shivered imperceptibly as Jen's half-flacid cock rubbed against her shaft, eliciting new sensations in her groin. She pushed Jen's back, a little startled.
"I... I think I should leave for now. I can't skip school like that. But I'll be back after school if you want... I'll bring you the homeworks and will keep you up to date with everything you missed." Claire said, blushing, as she was putting back her clothes and trying to wipe the cum from her body.
Jen's heart was pounding in her chest. "Are we... are we okay?"
Claire stopped for a moment, looking at Jen intensely. "Of course we are. You are very special to me... I just... I can't stay right now. I'll be back, I promise."
Jen nodded as Claire ran off with the strange warmth radiating from her bulge.
