At last Tim lets me drop to my knees. He needs time to catch his own breath and rest the muscles of his arm, which have been pumping like machine pistons.
He lets me moan on my knees for half a minute, then he reaches down and grabs me by the hair. He hauls me to my feet and lands a sharp judo chop to my belly.
"UUMMMPPPPHHH." I flop to knees, gasping as my deflated lungs suck air and ache burns in my belly.
Tim reaches down and pulls me to my feet by the arms. "Say 'I have a soft belly,' " Tim hisses. I hesitate. Out of the corner of my eyes I see the girls watching. Tim drops his right hand to waist-level, snaps it into a fist and drives it into my stomach.
"H-OOOOOOOO!!" I wail as I fall to the sand and roll onto my side, clutching my stomach with both arms. Tim looks down at me, grabs me by the hair and pulls me back up.
"Say it!" he demanded.
"I ... got ... a ... uuuuhhh! ... a ... soft belly!" I gasp. He winds up and plants a punch in the meat of my stomach. The soft belly absorbs Tim's fist, and he lets me drop to the sand and writhe.
Tim stands over me, breath coming hard, eyes aglint. He kicks me in the belly. With a sharp "UUH!" I take the boot to my gut and tighten up in my curl.
