Hours.

The big dick plunges in and out of Ms. K's hungry honey-hole for what seems like hours. With every one of the black MILF's screaming orgasms, you feel tired, like your limbs are made of lead. By the tenth orgasm, you black out...

No one ever sees you again, as far as most can tell. You just simply never come home that night, and nobody in the Society mentions you, in public. Heather and Connor doesn't seem to mind, though. Your wife tells your "son" the truth about Uncle Simon, and admits to having an affair with him and Penelope, among others. Connor understands, and goes off to college happily. Neither of the two seem capable of concentrating on remembering you existed in the first place...

Unofficially, Heather basically becomes a second wife to Simon, although she doesn't move in with them or speak it out loud in public. If you peeked in the bedroom window of their house some blissful morning, you'd find the Chinese stud getting double titfucked - his twelve inches of penis lovingly massaged in between two huge sets of mammaries, his beautiful Korean wife and Heather cooing with lust as they give that record-breaking manhood pleasure with their deep cleavages.
Penelope's fine with that, since Heather has made a name for herself as the best pussy licker in the area, and a smoking hot pornstar. After her hung husband is finished coating both their titties with his spunk, she joyfully licks it all off the other woman before moving onto cunniligus.
Ms. K helps out Heather with her living expenses, as well.

The police dutifully file the missing persons report, but make absolutely no progress on tracking you down.
