She takes it slow

You look over at Olivia in horror as she rapidly plows Vivian's husband. There's absolutely no way you could survive that with the size of the object currently inside of you.

"Don't worry, I'm only joking." Vivien says as she lightens her grip slightly. "The night's just begun, we don't want you breaking just yet." You're comforted by her words, but only for a moment as she soon begins slowly moving forward, her massive member burying itself deeper inside of you.

"Ooh!" You gasp unintentionally as you feel your insides being stretched to their limits in order to accommodate the new guest. The pain is not unbearable but certainly there, though there's something about the unique feeling of fullness as you continue getting stuffed by the monster phallus, that you focus on more.

"Feels good, doesn't it?" Vivien says as she pauses for a moment only to begin sliding back. You feel your legs shaking a bit as your insides shift again. "I bet you're starting to see why most woman prefer men with big, thick cocks. You feel it through your whole body." You grit your teeth as she continues pulling back. Your head slightly tilts over to see Olivia wildly slamming in and out of Dan as he loudly grunts and moans. "That's fun too though." Vivien says as your body adjusts again as she starts to work herself back in. Your legs and arms start to tremble as she begins to lightly pickup her pace, each inch moving through you sends waves throughout your body. Trying to take your mind off the feeling, you look back over at Oliva and Dan, just in time to watch cum spew out of Dan's cock as Olivia shoves the entirety of her fake phallus into him, holding it's position as the top half of his body collapses onto the floor. You feel another aching in your trapped crotch, unsure if it's from the scene you just witnessed or the continued **** on your ass.

It's not long before Olivia is standing in front of you, cock still attached.

"I think he's going to need a minute." Olivia says. You look back over at Dan to see him now completely collapsed on the floor.

"Don't worry, he bounces back quick." Vivien says giving you another long, slow thrust. "But feel free to join in." You're startled by her words, wondering how exactly Olivia could "Join in" at this moment. Clearly, Olivia has an idea as a smile appears on her face.

"How about it?" Olivia says pointing the tip of the strap on directly at you. "Wanna know what Dan's ass tastes like?"
