Jaskier see's Yennefer and Geralt in an intimate setting and gets the wrong idea. Will Geralt stop him before he makes a huge mistake?

Jaskier's POV:

I strum my lute and sing a slow romantic song to the crowd gathered in the bar and steal the occasional glimpse of my gorgeous Witcher. My fingers stumble over a cord and I hurry to hide my slip. No matter what I so desperately wish, Geralt is not my Witcher and never will be. He drinks with Yennefer and Ciri sits between them, her eyes roaming over a book of spells and enchantments. She told me Yennefer is helping her to control and master her magic. Geralt senses my gaze burning a hole in him and he turns his yellow eyes onto me. I blush and quickly turn my attention to a handsome young knight who stopped in for a tankard of ale. I sing the ballad and he smiles at me, revealing rows of nicely shaped, white teeth. He is fair looking with sandy blonde hair and bright green eyes. If I close my eyes I could imagine the man beside me with shinning white hair and glowing yellow eyes. He also seems to be quite strapping, at least what I can see under his armor. I smile back, despite my heart yearning for another. He reaches out and places his hand on my knee. I'm strumming out the last key to my song when a thud sounds from the table in front of us. I look over to see Yennefer whispering harshly to Geralt, as he fumes. His yellow eyes are narrowed and a snarl curls his lips, his hand clenched into a fist. She grips his elbow and pulls him back down from his half crouch. The knight beside me trails his hand up my thigh and I look down at him. He isn't bad on the eyes and he looks healthy. Perhaps I have found the man to give my first time to. Geralt throws his chair back and stalks out of the bar, Yennefer close on his heels. I look at Ciri and she smiles apologetically at me.

"Let me buy you an ale beautiful." The knight's voice purrs in my ear and I let him pull me away. Maybe ale will help me get over my nerves and sadness of my first time not being with the man I love.

Geralt's POV:

I shove open the doors and stalk into the stables, Yennefer follows close behind. Rage fills my mind and I send a fist through the wood of an empty stall. My knuckles pop and the skin splits, blood seeping over my fingers. Yennefer stands silent by the doors, her arms crossed over her chest as she watches my fit of anger. Roach snorts in the stall by her and she reaches out to brush her hand over his snout.

"Are you done?" Mild amusement coats her words and I grunt. She pulls me over to the benches and sits down. She tugs on my arm and I plop down beside her. She holds my hand and runs her sparking fingers over the broken skin. I watch as it slowly knits back together and the bones heal. I grunt my thanks and her violet eyes scrutinize me. I avoid her gaze and she sighs before donning her gloves.

"You can't just beat up anyone that shows an interest in him Geralt." I grunt and she rolls her eyes. She smacks my arm and I turn to glare at her.

"I'm serious Geralt! If you won't claim Jaskier than someone else will. He deserves happiness." I narrow my eyes at her and she smiles briefly.

"I didn't know you two were so close." Yennefer ignores the sarcasm in my voice and shrugs.

"I've realized that I haven't always treated Jaskier as I should and I'm trying to make amends for that." I study her and despite her attitude she actually seems sincere. I grunt, softer this time and she pats my hand.

"I know we had a fling once upon a time and I've moved past it. I want you to have happiness as well." Her voice is softer now, her expression less harsh and more hopeful. I manage a small smile and pat her knee. Despite everything that has happened between us, I am happy to have her as a friend.

"Thank you Yen." Yennefer settles against my shoulder and I lean my head to hers. She tells me how Ciri's schooling has strengthened her control over her magic and I grunt here and there to let her know I'm listening. Yennefer has taken over a sort of mothering role for Ciri and I am pleased that they have each other.

"Do you think he would truly welcome my advances?" I interrupt the comfortable silence and Yennefer sighs.

"I do. The boy is quite taken with you." I snort and Yennefer bumps my shoulder with hers.

"You are a catch Geralt of Rivia. Any person would be lucky to have you." Yennefer's words hit me deep inside but still doubt gnaws at my heart. How can I expect a beautiful, sweet man like Jaskier to love an unruly beast slayer like me? Yennefer settles on my shoulder again and I close my eyes as I think about Jaskier.

Jaskier's POV:

I step outside for a breath of fresh air and to secretly look for Geralt. He stormed out of the bar earlier with Yennefer and we haven't seen them since. The dark seed in my heart whispers to me that they are probably having sex but I shake my head to dispel such horrid thoughts. I hold the carrots I bought from the bar keeper to give to Roach and make my way to the stable. I notice the doors are slightly askew, as if a storm came through them. I move to push them aside when the trail end of a conversation floats through. They speak to low for me to make out the words but I recognize Yennefer and Geralt's voices. I peek through the slit and cover my mouth, as my heart cracks just a bit more. I'm not sure how much more it can take before it just finally shatters all together. Yennefer sits beside Geralt, her head resting on his shoulder and their hands clasped together. I watch as he lays his head on hers and closes his eyes. I grip the carrots in my hands and quietly back away from the stables. I push back into the bar and shove them into my bag. Ciri watches me with a worried expression but before she can ask, the knight from before slides in beside me.

"How about you play a private song, just for me?" His eyes gleam with lust and he trails his hand up my thigh, briefly grazing my cock through my pants. I gulp down my ale and before I can think better of it, I nod. The knight grins and grips my jaw with his other hand. He tilts my face up and crushes his mouth to mine. I close my eyes and think of Geralt. The knight forces his tongue in my mouth and I rip my lips from his. He grins at me and grabs my hand, pulling me to my feet. A delicate hand grips my tunic and I look down at Ciri.

"Perhaps you should wait for Geralt to come back. He won't be happy to find you disappeared." Her eyes are wide as if urging me to realize something. The ale burns in my stomach and my mind becomes fuzzy. I feel lighter and more carefree than I was earlier. I smile at her and untangle her fingers from my tunic.

"I'm sure he is busy with Yennefer. He won't even notice." The words are sour in my mouth so I turn to the knight and let him kiss me again, this time allowing his tongue to invade my mouth. Ciri grunts and rubs her eyes as if frustrated and I let the knight pull me towards the stairs. I look back at the doors and my feet stumble on the stairs. The knight grins at me and palms my ass. I can feel his cock through his pants and the alcohol inside me makes me flush with arousal. Perhaps this will be easier than I thought. He steers me towards his room and the stairwell spins. I grab onto the knight to steady myself and he shoves me face first against the wall, thrusting his cock against my ass.

"Can't wait to take it up the ass, can you?" He rasps in my ear and I close my eyes. He pulls me into his room and closes the door behind us. No going back now.
