it didnt resemble so much sexual congress as the energetic toying of a very big animal with one of its young : hed been tossed this way and that , pounced upon , rolled across folds of soft slippery flesh , squeezed and playfully bitten , slapped and slobbered over , and only once or twice had he felt his penis , as unresponsive to the rough play as a boneless finger , enter the moist softness of moraxas mouth and genitals .
