Giantess Stepmommy Game Night

Stepmommy has prepared a board game night for you and your friends, and even bought a new "energy substance" that she heard about . When she leaves for the shower, you and your friends take it and shrink to miniscule size, adventuring the board games.
She is upset when she thinks you left and answers the door for one of your late friends, who decides to keep her company for the evening.
They play the board games, all the while stepson is stuck in her panties and watching the casualties. Your friends do everything they can to get her attention, but it's no use since they are so tiny.
Some of your friends get stuck in the chips and gummies, getting swallowed and digested.
Some get knocked off the table by dice and stuck to her feet before getting stepped on.
A few get caught up in tumbling dominos and meet their fate ..
And at last she yells check mate! during a game of chess, squishing another pal of yours. She begins flirting with your friend that is playing with her, and they end up getting intimate... She falls back, sitting on the chess board repeatedly and squishing your remaining friends as she kisses him. Passionately, they begin fucking while you explore her nipples, finding your way to her mouth. You thought she would notice you but she sucks his cock with you on her tongue, then you get stuck to his massive dick and penetrate her ...caught up in all of it while she moans " we can't let my stepson find out!" After finishing you get tucked away in her cum filled panties...
