She's impressed...

"First of all... I must say I'm quite impressed with that performance of yours.... How did it feel to fuck your own mother...?" The voice says with a giggle on the other end.

"You... you watched us...?" You stammer in shock.

"Well duh! I kinda have magical powers if you haven't figured it out..." She scoffs before adding with a giggle, "If I can turn you into a woman its not much a stretch that I can watch you fucking that gorgeous and apparently very sensual mother of yours..."

"Stop it..." You studder.

"Mmmm stop what John? Stop talking about how you slid that cock deep inside your own mother's tight pussy as her perfect body rode your cock?" Giggling on the end she adds, "Because that was really hot... Mmmmm but not as hot as when you came inside her..."

"Fuck..." You moan softly, your cock twitching.

"Settle down now John... See while it was fun to watch you did take a bit too much time..."

"Oh fuck!" You shout as you hold the phone on front of you and see it has already been an hour and 10 minutes.

Your heart races as the woman laughs on the other end, your hand shaking as you put the phone to your ear and plead, "Please... I didn't mean for it to take so long... I..."

"Oh stop.... You sound so pathetic when you beg like that." The voice says on the other before adding, "Besides you were about to waste more even time jerking off weren't you...? What should I do with you...?"

"No... I... Please don't..." You whine before she cuts you off.

"Relax... I think your performance with your mother was worth giving you some extra time." She says in a soft, reassuring tone.

"Thank God..." You mutter before she adds,

"But... I think that means you owe me another equally as fun show. I expect to be just as entertained watching you and Gwen. Don't disappoint me or the deal is off..."

"I won't! I promise." You reply eagerly, saved once again from her wrath.

"You should get going John... I said one more hour and it's already been 15 minutes over the last one I gave you..." She says wickedly.

"Oh come on that's not fair!" You complain.

"You really are unattractive complaining like that John... Why don't you focus on fucking Gwen instead of whining..." Giggling she teases, "I know you've been thinking about teaching her a lesson long before I started toying your life..."

"How long have you been watching me?!" You ask in shock.

"Well time to go! Good luck! I'll be watching..." She adds with a laugh before hanging up.

You wonder how long she has been watching you before taking action... But for now you know you have less than 45 minutes to fuck your sister lest you face her wrath...
