While sitting on the couch watching tv, my sister comes home after a late night out. She is on the phone crying, something about her boyfriend and his friend not fucking her? I try to ask what its about, but she runs to her room. I follow where she fills me in. As I go to leave her room, I get an idea. I've had this experience and I can give her some help going through positions and such. She reluctantly agrees and soon she is sucking her dildo on the mirror like a champ. I start fingering her wet pussy and asshole, before she turns to give me a blow job while riding the dildo. After a bit of that, I spin her around to fuck her while she sucks the dildo. Then I drag her to the bed and fuck her throat while she fucks herself with the dildo. We finish with her getting face fucked while kneeling and I give her a massive throat pie. I think my little sister is ready for her first threesome!
