<br/>Marianne looked at Betty, who was still sucking giant cock.  "I wonder what Mom would say," she wondered aloud as the giant laid down.  That huge phallus stuck up into the air.  She looked at it, a little scared.  "That thing is huge.  But then I'm sure I'm not the first girl to tell you that.  Just be gentle with me, please?  I'm not like my sister, okay?"  With that, Marianne straddled the giant's hugeness.  Her bare breasts jiggled as she positioned the cockhead between her thighs.  "Remember I'm trying to please you."  She reached out and patted the giant's hairy stomach.  Then, she lowered herself.  "Sheesh that head is big...uh...gagaga..."  The head began to part her pussy-lips.
