Your hand fully covers over his whole girth, and as fun as it is watching his face and hearing his noises, from behind you don't get the view you were really hoping for. With his warmth in one hand you reach into the satchel removing out a shrinking potion. You silently set it down on your side, but you doubt even dropping it would gain his attention as Ivan practically tearing up looking at the ceiling with your motions. You pop off the top and let go of the fairy's member, he starts recollecting himself and you push him off your lap making sure he's separated from you to avoid spilling over as you pour a chunk of the mix onto the fairy boy. He keeps shaking his head to the sides as he notices the shrinking take place. Your legs spread to the sides as he dwindles down below between your open legs. When he finally stops shrinking only halfway up in height of your thighs, you smirk down at his wildly shaking head that keeps looking left and right just down your legs.
When he finally turns around to look up at you, you have to lean forward to reveal your face. Your giant face to the scared little fairy, making you feel like you yourself are a human and caught a little fairy intruder yourself. You pull your hand up in the air, aiming your palm at him and wiggle your fingers while holding them in a grabbing claw position. Ivan panics and goes to his feet as he's about to jump and fly away. His reactions aren't fast enough as he only makes it slightly above your spread out legs by the time you grab him.
"Excuse you, I thought you and I were having fun. You're not just going to get off and bail from me are you?" Holding him in your grip, his face shaking side to side. You just want to squeeze that panicked little head, holding him still with only two fingers unable to escape from your full control. Instead you open your grip and he falls backward, now sitting in your palm. "C'mon Ivan if I was going to do something really violent to you, I wouldn't make such a show of it. We're having fun." He calms down a bit, and you smile innocently at him. Thinking that if you were going to do something more rough you absolutely would put on a show, and the thought of maybe doing it later still persists in your mind.
Though with the innocent still fearful faces he's making, you'd rather play with him right now. He just keeps staring at your fingers laying out around him. You bend them so they tower over his sitting body, making him shiver and you giggle. You quickly shake your wrist rocking him in your palm, almost dropping him. When you hold back still upright, he places his hand in your palm to hold himself in balance, and you bend your thumb inward placing it right on his crotch. His hardness from earlier still persisting, but now you watch him sprawl onto his back, head resting on the bottoms of your fingers as you circle your thumb around his crotch, pushing in on his stomach and thighs as well as you keep up his circles of pleasure. He keeps squirming and groaning then moaning as you make each connection. You start laughing while you keep doing it, his lack of control as you just keep doing the same pattern and hear the same pattern of noises from his mouth. You have to stop as you laugh in front of him. He looks almost ashamed at it, which with his tiny size you find cute, but you're ready for something a little more.
