Exactly as Lucia described

"Alright, Lucia, that's enough." You said as you grabbed your wife's hair and pulled her away from her sister's slick asshole. "It's time for Rosa to decide how she wants to be fucked." You gave Rosa a cheeky grin as she turned around to face the two of you. "We must be good hosts after all!"

"Yes, Master!" Lucia said as she resumed riding you upright and began playing with her clit.

Rosa took a second to think about it and to drink in the sight of Lucia riding your reverse cowgirl and pleasuring herself while you pulled her back by the hair. "I think I'll go with our little slut here's recommendation. Give it to me hard and fast!" As she said the last part, she took one of Lucia's nipples in each of her hands and pinched hard.

"Ahhh!" Lucia screamed in pleasure. "Please pinch me harder, Ma'am! I can take it!" Rosa pinched her nipples as hard as she could, and Lucia starting rubbing her clit even faster. "Ahhh! Thank you Ma'am! Please don't stop, I'm so close! I'm so close!" You pulled her hair hard and smacked her ass as hard as you could from your position. "I'm so cl-aaahhhhh!!!!"

With that, Lucia's eyes rolled back as her orgasm released wave after wave of pleasure throughout her body. You released her hair, and she fell forward almost directly into her sister's DD tits. Rosa caught Lucia and held her to her bosom while you maneuvered out from under Lucia and stood up, joining Rosa. Lucia rolled to the side while she tried to catch her breath.

"Well," said Rosa, "she had her fun, so I guess its time for us to have ours! Let me just clean you up a bit first."

Rosa sank to her knees and began licking her sister's juices off of your dick, moaning approvingly at the taste. After she was satisfied, she stood up, and looked you in the eyes. "Don't forget," she said, "I like it even rougher than she does!"

With that, she climbed onto the bed and got on all fours, swaying her ass teasingly at you. Not needing any further invitation, you quickly joined her on the bed. Lucia reached up to lining up the head of your cock with her sister's entrance. Once everything was aligned, you pushed your manhood into Rosa's dripping wet pussy.

Rosa moaned "Mmm, Lucia wasn't exaggerating, you feel so fucking good!" Lucia re-positioned herself so that her head was now in the same direction as her sister's. "I told you it was amazing!" She said.
