Emma's sister!

Not in a million years would you have guessed it... Emma's own sister. Holy cow!

You quickly close the video and throw Emma's phone back on the bed. You don't want Emma to know you know that it was her sister she shared with you.

You know you turned Emma into a slut, but even this surprises you. You didn't program her to be into **** - you just mentioned a girl and that's where she went.

You think back to the evening - you know you heard Emma and the other woman... her sister... kissing. You think you even heard them playing with and suckling on each's breasts. Did they finger each other as well? Did Emma insert a finger into her own sister's pussy? Jesus, you're so hard.

You've always thought Emma's sister is hot. You've ogled over her cleavage and stared at her ass many, many times. She's got much bigger boobs than Emma (as you expected the mystery woman to have), and fortunately she's not shy about showing them off. She also loves wearing yoga pants too, so whenever you are around her you're daydreaming about fucking her up her tight ass. You've thought about fucking Emma and her sister in a hot incestuous threesome dozens of times... and holy shit you actually did it... you just didn't know it at the time.

Were they making eye contact when they shared you. When Emma sucked your dick was she watching her sister's pussy lips slide back and forth on your tongue? When Emma kissed you after her sister came on your face did she think as you did that her sister's pussy tastes amazing? When Emma's sister came - both times - was she excited to have her own sister watching her. Was it extra exciting to be fucking her sister's boyfriend?

It takes four torturous hours to distract Emma enough for you to sneak onto her phone and forward you the video. Then you run off into the bathroom for some alone time.

You watch Emma's sister's illustrious breasts sway as she bounces up and down your cock. You stroke yourself and wonder if Emma has already touched herself watching this video too. Did Emma and her sister play doctor when they were kids - did they experiment together? Is that where this began, you wonder.

You cum the fifth or so time you watch Emma's sister burst into an orgasm. You can't see your sperm pump into her pussy in the video, but you know that's what's happening and it really turns you on to know that being inseminated by you is what really triggers Emma's sister's orgasm.

You wash your cum off your hands and begin to think about how you can push things further with Emma's sister.
