A TABOO SHENANIGAN

In the third installment of A Taboo Series, you and STEPsister find out you are not pregnant *phew* but she has decided maybe the two of you should cool it and stop the shenanigans after having a close call. But a few days later when the pregnancy scare is farther in the rear view mirror and STEPsister is horny from abstaining for so long, she starts covertly touching herself under her skirt beside you in the back seat of the car while STEPMommy is driving you home from the movies, and then makes up an excuse to stay in the car with you as a mildly suspicious STEPMommy parks the car in the garage and makes her way into the house (in the absence of a green screen, please use your imagination to envision the car being driven down the road until STEPsister takes her seatbelt off). Emboldened by all the consequence-free creampies, STEPsister has changed her mind and needs to get fucked again. She slobbers on your cock in the back seat of the car, then begs you to hurry up and fuck her before STEPMommy comes back around. You fuck STEPsister in missionary and doggy in the back seat of the car, her moaning the whole time about how much she missed your cock and how good it feels inside her. Unbeknownst to you both, STEPMommy has come back out to the garage to check on you and freezes in her tracks at what she sees happening inside the car. Multiple emotions seem to pass across her face until we see her begin to slowly rub herself over her yoga pants. At some point, she notices there is no condom between your cock and your STEPsister's bare pussy - this gives her slight pause, but STEPMommy continues her voyeurism from the corner. Unaware of STEPMommy's presence in the garage, STEPsister begs you to cum inside her, and you fill her to overflowing. Post-orgasm, you notice STEPMommy in the garage doorway. You and STEPsister are caught. STEPMommy is speechless with her hand down the front of her pants. Cliffhanger.
