Bill’s hand delicately wrapped around Thumper’s shaft. He ain’t stroke it, he just held it light as a egg, and Thumper slowly rubbed his dick back and forth to hump his hand.
Bill gulped and closed his eyes, then he stepped away from Thumper. “No. You’re not… you don’t have a complete erection, so…”
Bill was all about erections — he said a man shouldn’t be guided by lust, and jacking off too much was being guided by lust; “too much”, he said, meant getting yourself hard deliberately. Jacking off was only okay if you got hard accidentally and needed to do it to “relieve an erection”.
