Getting the cow out of there had to come first. 'I can't concentrate like this, i have to stop this now!'
You focused, trying to find the connection between the two of you.
It took you a while, and you lost it twice because you were surprised by a sudden thrust, but you finally managed to catch a hold of it.
"Now i just have to-nngh!" You were about to transport the cow to you, when you were interrupted again, breaking the spell.
'Dammit, i keep getting interrupted!' You gritted your teeth. 'I'll just have to make the spell keep going after i start it. I can do this!'
The loss of concentration made you lose the connection again, forcing you to search for it again.
Having to deal with the feeling of getting fucked senseless for even longer due to that made you irritated and impatient.
'There! Now i just have to start the spell and pull her over!'
You focused, trying to ignore the sensations, while strengthening the connection and locking on to her.
It didn't take you long and you immediately started casting the spell, afraid the connection would be interrupted again.
But just when you were about to finish the spell you were interrupted by a thrust hard enough to make you collapse onto your desk again.
'Dammit! Now i'll have to start ag- huh?' You were about to start over again, when you felt the light draw on your mana,
signalling that you had successfully cast a spell. 'What? I was definitively interrupted...'
You froze. 'Did i accidentally complete the spell? But i was distracted, i have no idea what it could do! I have to stop-'
Unfortunately, that was when you remembered that you had set the spell up in a way that would prevent it from being interrupted.
'Can i really only wait and see what it will do?' You clenched your fists in frustration.
There was nothing you could do, at least not in the few moments you still had before the spell fully activated.
You could only hope that the spell hadn't gone too far off course.
