Your student Natalie needs an A this semester so she invites herself over to "flirt" with you, but you both know what & why she's really here. She starts unzipping your pants & is surprised you're not super hard already in anticipation... oh you ARE hard, ok, got it. Her face shows the disapointment but she tries to hide it. She's going to ride you so she climbs on top and ummm it's in right? Ok, she starts going up & down but she goes up and it falls out. Oops... ok let's just get it back in... and she thinks it's in but not totally sure.... Oh boy.... this is much harder than she thought... she's just never seen one this... small... ugh... lol it fell out again. She puts it in one last time & tries riding and you start cumming but it FALLS OUT just as you're cumming and RUINS your orgasm! uhhh yeah... she's definitely earned that A now
