Bro and Sis Prank Wars

Description: Bro vs sis prank wars since my step bro moved in, we've had a bit of an ongoing 'prank war', and i've been meaning to get him back for a few days now. on the phone to my friend i explain that today's prank will top them all i have put extra strength viagra in his energydrink, so he'll be walking around hard all day !! little do i know that he also had a similar idea.. and before i realise i'm furiously masturbating, trying to cum but with no luck. i suddenly see he has been stood in the doorway watching me finger and fuck myself with toys... perhaps a real cock would make me cum? after all.. it will be rock hard for a while ;) super taboo dirty talkinvolvement of my 'mum' walking in to berate us but we just carry on! taboo creampie over 20 mins of filth :p
