Aiden found his eyes widening in pain as she grabbed his balls. He made sure to note obviously his dick did have a very strong effect on her but, next time he'd have to play it differently. Either by having when she needed it or presenting it in a way in which it wouldn't be so easy for her to lash out at him. He'd wait for the pain to subside before he rose and started making his way back up the stairs. If she was there waiting for him he might get a nasty surprise but he wasn't concerned, she needed what he had, and with enough time she'd go to any length to get it. She'd learn to play nice, or see how far from the limits of dignity it was she could fall.
