Zany squeezed Andrew's head tightly as if trying to resist the pleasure she felt. Even her moans were muffled as if she didn't want to let Andrew know that she enjoyed it.
Andrew on his part was amused to see how she tried not to break her composure and wanting to see how long she would last, he sucked and massaged her tits with greater force.
Zany's breathing was beginning to hitch and little by little she was losing the battle, so Andrew, wanting to give her the final blow, gently bit one of her nipples.
An electric current ran through Zany's body that, unable to bear it, she let out a loud and erotic moan. Andrew smiled when he heard her, but then he realized that Zany's entire body was shaking.
Surprised, Andrew withdrew from Zany's breasts and carefully observed the girl who fell limply on top of him. Andrew, even in his surprise, immediately threw his hand to Zany's crotch.
