Swelling
Tabit caught hold of him and helped him get up. Her touch brought a zap of electricity down his body. He was so hard that his balls were tight. But now he feared another situation. What if he came again if she touched him again on his erection? He sure couldn't get in the same situation twice in a row. "I can walk," he lightly protested.
"No," she admonished him. "You have a lump in the back of your head. Come, hold me."
Fafnir had been to so many battles that a mere lump was nothing, but the fact that she was holding him and caring for him, floored him. It was impossible to put distance between them but what should he do with his strained erection? He decided that he wasn't going to allow her to touch him over there.
