I Invite a Friend to Stay at My House and My Stepson Join Us for a Threesome

I INVITED MY FRIEND HANNAH TO MY HOUSE. SHE WANTED TO TALK TO ME BECAUSE HER HUSBAND HAD BEEN UNFAITHFUL. SHE DECIDED TO STAY THE NIGHT. MY STEPSON WAS ALSO IN THE HOUSE, AND HE CAME INTO MY ROOM TO TELL ME HIS AIR CONDITIONER WAS BROKEN AND IT WAS TOO HOT. I HAD NO CHOICE BUT TO LET HIM SHARE THE BED WITH US. HE CONVINCED ME TO HAVE SEX SINCE WE WERE BOTH VERY HORNY. WE TRIED NOT TO MAKE ANY NOISE, BUT HANNAH HEARD US AND DECIDED TO JOIN US.
