You hear your sister calling you from the bathroom so you go and see what she wants. She’s in a towel and acting oddly and then she admits to using your lotion, confused at first than she shows you, your upset but also amused so you toy with her she has NO CLUE what she just did, but when she gets upset and flings some in your direction you know exactly what is about to go down. You and your sister are going to fuck. The pheromones alone in that small about you had left is more then enough and neither one of you is going to be able to resist the overwhelming pleasure and desire that is about to drown you both… and before you finish thinking about leaving the room your fingers are already sliding into your sisters wet pussy. Still trying to resist but failing completely your sister sits on the bed and notices as shes rubbing her nipples they’re cumming? You laugh, your lactating you heard that can happen if the girl is ovulating at the time but just tell her she’s lactating, and it is turning you on insanely. So you give in, take out your cock and let nature run its course… You fuck your sister and it’s the most she’s ever cum in her life, and she’s got a filthy mouth, huge milky tits and she’s a squirter.
