Valentines Day is coming up and you've always wanted a filthy threesome with your wife Roxy and sister Brea. But there's a problem they absolutely despise each other and don't get on at all. You come up with a plan to get them to go along with it, you managed to get your hands on a love potion and will make anyone become infatuated with you if you spray them with it. You invite your sister Brea round and ask her opinion about the perfume (which contains the love potion) you bought as a gift for Valentines for your wife, you spray the air and as she inhales it her manner changes and she becomes mindfucked. Your own sister in now under your control and willing to do anything to please her brother. You tell her to strip out of her clothes and to start sucking your cock, she's become completely submissive. Smiling and eager to satisfy her brothers big cock. In the middle of the blowjob, your wife Roxy walks in to catch your sister sucking you off. Your wife is disgusted at this display, she can't believe you've been cheating on her with your own sister! She knew you two were close but this is something else, your wife questions why she just sits there smiling. To shut your wife up you spray her quickly with the love potion and her behaviour towards you completely changes. Now both your wife and sister begin sharing your cock, worshipping it and sucking it. They both are your submissive sluts and want to fuck your cock. Your sister rides you reverse cowgirl, grinding on your cock while your wife watches and plays with herself waiting for her turn. She gets so horny knowing your fucking your own sister in front of her. Your wife hops on your cock next cowgirl to ride you to orgasm. Suddendly the love potion wears off and they return to normal. They can't remember anything that just happened, both are naked and start arguing with each other. You claim it was their idea all along and they are both extremely embarassed & continue to blame each other.
