A eeck would emit from Mari, as the hand smacked her again hard on the ass.  While the imbued phallus began to fill her with the warm semen.   Breasts and perky nipples rubbed incessantly so against her backside.   Mari would reach back with her hands.   For a moment her hand searched, then her fingers would find each nipple.  She begin to tweak and pinch those said nipples gently.  This through would take away any leverage against her being pounded and held against the billiard table.
