Amanda

Your sister climbs up onto the bed in front of you, pulls her panties off, and spreads her legs. "Eat me out sis."

You hesitate at first, but she grabs your head and forces you down onto her. You've only eaten a girl out once before, but you think you remember enough to do a decent job. You start licking slowing around her lips, then start penetrating her, licking in rhythm with Lilly who's still fucking your ass.

This continues for several minutes before you feel something wet on your dick. You turn your head slightly and see that Alex is standing in the corner still filming, but Katrina is no where to be seen.

Amanda laughs, "Your little crush Katrina is finally sucking you off little sis... I bet you never imagine it happening like this though!" Your face immediately turns red and you almost start to cry. Even though she's giving you head right now, you know that it's part of this sick joke and you'll get to be with her after this. Tears start streaming down your face and your sister picks on you more, "Is the sissy girl gonna cry now? How adorable!"

Eventually the pleasure overpowers the devastation and you start moaning into your sister's pussy. You can feel yourself getting closer to cumming with every second, and eventually it's too much to hold back and you blow your load into Katrina's mouth. She pulls your head away from your sister and starts making out with you, pushing your warm spunk into your mouth. "Be a good girl and swallow that for me baby." You do as she says then return to eating out your sister.

Eventually the girls get tired of fucking you and stop. You pull your panties back up and wipe your sister's juices from your mouth. Your sister smacks your ass again before saying, "Go get cleaned up and go to bed sissy. We'll make you feel pretty again tomorrow. You can keep the clothes by the way, you're gonna need as much sissy-wear as you can get!"

Without saying a word you start walking to your room. As you leave you hear Lilly say, "Marcia's such a good little bitch, I almost want to make her my own personal slut!" and Alex replies, "But then we wouldn't get to share her with our friends!" The girls share a giggle and you walk back, wondering what they meant by friends.
