While this certainly centers around girls who romp with their sisters' boyfriends, there is also an element of comedy that can’t be ignored. Take Maya Woulfe (non-sex role), who gleefully tells her sis, Charly Summer, that she and her boyfriend, David Lee, are engaged and she wants her to be the maid of honor. Cue the comedic music and Lee’s exaggerated expressions as, unbeknownst to Woulfe, he watches an unabashed and exhibitionistic Summer through the clear tabletop as she spreads her legs wide to tease and entice Lee. And, naturally, once Woulfe departs to spread the joyous news, Lee and Summer knock off a piece.

Kiara Cole (non-sex) poses for selfies with boyfriend Jay Romero until her younger sister Kate Bloom asks him to take some pics of her. He agrees, and suddenly Bloom strips before the couple, Cole storms off, and he remains to tale more pics—and do Bloom.

Delilah Day, the bad sister who is known to go streaking and flash and tease her sexy body on a moment’s notice, or “accidentally” spill water on a flimsy T-shirt, or bend over to pick up the keys sans panties, does an excellent job doing all of the above, and more, to entice, then pleasure, lucky Alex Mack. Aften Opal flashes then does Donny Sins in an outdoor Jacuzzi and includes some near balls-deep oral on the surprised, and impressed, stud.

It is often more of a fun rather than dirty (at least in the beginning, anyway!) come-on bordering on lecherous innocence that teases and pleases the hell out of the guys.
