Try for the hat trick.

"Well, buttholes are usually stretchy, right?" They nod. "So I guess those slippery cocks can all find a home in here. Come slide that clear goop on me."

"Oooh, that sounds good," Cindi says as she bumps Tammi over. They don't just stop at your hole, but quad trails of precum snake over each butt cheek as each girl picks a side. They each grasp a cheek and knead it roughly.

"Isn't that a nice ass Cindi?" Tammi asks her twin.

"Totally fuckable, I can't wait to feel my cocks inside of him next to your cocks, sis," Cindi replies. They poke you all over with their cocks for a long time. You thought they would get right to it, but it feels good and it is good to be appreciated and desired. "Well I think we could poke and prod his butt all day until it drips with our clear slime, but I'd enjoy it much more if we got some penetration. So Tammi you have bottom. Let's make ourselves a cock sandwich!"

Tammi guides you over to the couch and lays on her back and holds her cocks straight up for you. You climb on and stradle her cocks and play with her titties a bit before she slaps your ass with her cocks to remind you of what she wants. Cindi has climbed behind you already and lays over you and pushes you downward so that you are sandwiched between two nice sets of soft tits. Her heavy and huge ballsac rests against the bottom of your ass on top of her sister's. Then you feel cockheads sliding around trying to find your hole. It doesn't take long since you are bent over and spread wide.

The first cock to enter you slides in easily, you hardly feel it. The second stretches you a bit, but goes in smooth with all of the lube helping it along. "Who's cocks are those?" You can't tell from this angle and don't want to move your hands from the sides of Tammi's breasts which feel great squeezed out from between the two of you.

"That's all me, honey," Tammi says before giving you a deep kiss. "You are wonderful for giving yourself to us like this. I can't see guys doing that."

"I use lots of toys," you affirm.

"That's good," Cindi replies. "I'm sure you are going to reach new limits though," she tells you as she pushes at you with her first cock. It slides in suddenly with how slippery it and you are. It almost hurts, but just becomes an uncomfortable stretching. You don't know if you can take the last one.
