Molly was awakened by a touch on her shoulder. She groaned. She had a hangover and it took her a minute to remember why she did. She felt her shoulder being poked again and turned her head. She had to pull the hair out of her eyes to see and blinked. A round, black face, under a round, black afro, was right in front of her. Brown eyes were staring into hers.
“Could you please tell me why I’m naked, hung over, and in bed with a naked white woman?” Delores’ voice was soft, as if she was afraid someone else could overhear her.
Molly sat up like her abs were spring steel. She looked down and saw both of her bare breasts, and then the pain hit her and she fell back down and covered her eyes, pressing the heels against them in a vain effort to make the pain go away. She groaned piteously.
“Me, too,” said Delores, still soft. “I still need to know what happened. Did we...?”
The pain slowly abated and Molly turned her head again.
“I don’t know anything right now. No. That’s not right. I know you. You’re Delores. We drank wine last night.”
“Is that all we did last night?”
“What do you mean?”
“We’re blasted, naked, and in bed together!” She had spoken too loud and closed her eyes as the noise flayed her mind.
“I remember I like you, but I don’t think I like you that much,” moaned Molly. “Where are the children?”
“If you have a robe I can borrow I’ll get up and go look for them.”
Molly rolled onto her side and slowly sat up.
“I have two robes. We’ll go together. We seem to like doing things together.”
Molly stood up. Her hair was a rat’s nest but she was still tall, slim, heavy up top, and beautiful.
“I see why my son wants to bang you,” said Delores, who also sat up and stood, shakily.
“You’re still drunk,” said Molly.
She went to a walk-in closet that, on the other side of town, might have been called a bedroom, based on the size. She emerged with two summer robes. She handed the silk one to Delores, who looked at the Asian motif on it, made up of cranes, wading in water. She slipped it on and sighed.
“If you ever decide to throw away your clothes, I’ll do it for you. Not everything will make it to the Salvation Army, though.”
Molly shrugged into her own robe.
“I have a feeling we’re going to share other things, too,” she said. “I have a jar of sweet gherkins in the fridge.”
“Why are you talking about pickles?”
“Brad drinks it whenever he has a hangover. It seems to work pretty well for him.”
“Pickle juice?”
“I also have aspirin.”
“White people are strange.”
“No we’re not. We’re just a different color of black.”
“I never heard that one. Can we be a different color of white? People might treat me better that way.”
“If anybody gives you any shit, you tell me and I’ll crush them.”
“You’re pretty but you don’t look like an MMA fighter.” Delores tied the belt on her robe, which showed an acre of dark cleavage.
“I have a guy for that,” said Molly. “In fact, he’s one of the people I think we’re supposed to be looking for right now.”
“Ohhhh, no. Don’t you get my boy mixed up in no fisticuffs. He’s a lover not a fighter.”
“I was thinking that he’ll outsmart them and make them look ridiculous.”
“Where is this aspirin you claim to have?”
“Bathroom,” said Molly, pointing to a doorway.
Delores went in, pulled up the robe, sat, and peed. She wiped, stood, flushed the stool, and then looked for a medicine cabinet. She finally found one that was set into the wall. The door was a picture of a Victorian picnic and you had to push one edge of the door inward to unlatch the magnet that held it shut. When she opened it there were only three things in it. She reached for the bottle of Bayer Aspirin, which occupied its own shelf. There was also a container of Nyquil and a small box of Q- tips. She closed the door and looked around. There was a glass wall, behind which was what looked like a shower. There was a long counter in which twin sinks sat. Everything gleamed. She popped two aspirins and used her hands to catch water and drink. She dried her hands on a towel that felt like it was too soft.
“You could house three homeless people in that bathroom,” she said, when she came out. Molly was still running a brush through her hair.
“When my divorce is final you can move in with me and decide which homeless people get to live in my bathroom.”
“You’ll still live here?”
“No. I’ll probably sell it and live in a normal house.”
“What makes you think you’ll get the house?”
“Sweetheart, I’m going to get everything. I’ll have the goods on him before I file. He makes enough that he can just start over with his little girlfriend and they can live in a cottage like honeymooners.”
“Remind me never to get on your bad side,” said Delores.
“You want to try the pickle juice? My mouth is dry as a bone.”
“Hangovers are caused by dehydration,” said Delores. “I don’t see how pickle juice could rehydrate us.”
“We’ll chase it down with a glass of water,” said Molly. “I have to try something, if only to convince myself that things should be getting better.”
“What the hell. I like pickles. Lead the way.”
“I found our clothes, by the way,” said Molly. She pointed to a vanity table, which had two neatly folded piles of clothing on it.
“That doesn’t look like what I would expect it to if we took our own clothes off,” said Delores.
“I agree. There are so many questions. Pickle juice, water, then children and answers.”
They reached the kitchen, which was situated next to the dining room and great rooms, which were in the center of the house. The bedrooms other than the master bedroom were on the other side of that center. A hallway with three bedrooms in it was below an identical hallway up a flight of stairs. A sliding glass door led from the kitchen to the pool area. Molly got the jar of pickles out of the fridge and poured an ounce of juice into each of two glasses. She extracted a Gerkin, bit half of it off and offered the other half to Delores, who accepted it and popped it into her mouth. The women looked at the glasses, each other, and then tossed off the juice as if it was a jigger of bourbon. They filled the glasses with water and drank that. Molly put her glass on the counter and said, “Follow me.”
They walked by the patio doors and Delores stopped.
“Wait,” she said. She pulled at one door and it slid effortlessly to the side. She walked out and stood over something lying on the pool deck. Molly followed.
“There are parts of bikinis all over the place,” Delores said.
“Which means everybody in the whole house got naked last night.” Molly frowned. “How much do you want to bet that we find all of them in the same place?”
“I don’t have money to bet. What will we do if they are all in the same place?”
“I do not know. I have never been faced with a situation like this. You and your children have made my life interesting.”
“What is that Chinese curse about living in interesting times?”
“I don’t think you’re a curse. I just think you’re interesting. You have brightened up my otherwise boring life.”
“Thank you. I have never met a white woman like you. You break the mold.”
“I think the mold needed to be broken. That’s why all this is happening to me.”
“Where might the children be?”
“The other bedrooms are this way,” said Molly, going back in the house.
Molly went to Robin’s bedroom first and they hit paydirt there. All three girls were semi-draped over Marcus, who had a magnificent example of “morning wood”. Everybody seemed to be asleep. Delores stepped forward and began to bend and look at things. When Molly joined her there were clear indications of what had transpired. The sexual lips of both of the black girls were crusted white with dried semen. There didn’t appear to be the same thing on Robin’s lips.
Delores stepped back and her hand went to cover her eyes. She turned and left the room. Molly followed, for lack of anything better to do.
“I am so sorry,” moaned Delores.
“Why?”
“My children should not have engaged in that ... activity.”
“I thought they do it at home on a regular basis.”
“What?” Delores stepped back, looking alarmed.
“Last night. You told me that there is no modesty in your house and that Marcus teases the girls and you with his erections. Marcus told me he is the man of the family in all ways. It doesn’t take a rocket scientist to understand what that means.”
“I wasn’t supposed to tell you that and they weren’t supposed to do it in front of your daughter.”
Molly waved a hand.
“I remember saying I wasn’t going to judge and I feel the same way today. I mean look at him. Any woman would crave playing with it. Does he have a grandmother? Because if he does, his Nana might even want to play with it.”
“I just do not understand you,” said Delores, softly. “Anyone else would call us all perverts and call the police.”
“I don’t think you’re perverts. They obviously don’t think they’re perverts. If something happened between you and me last night, that might be perverted, but I think I’d remember that and I don’t. All I remember is falling in the pool when I went to talk to the girls about being topless.” She blinked. “They were doing it right in front of us!” she moaned.
“We were getting sloshed and they were playing doctor,” said Delores. She turned. “I need to get home. I need to find out if my daughters are going to become mommies.”
“I don’t understand,” said Molly.
“Our family menstrual calendar will tell me if they were fertile last night. They’re not supposed to do that if they’re close to being fertile.”
“We can get them Plan B if it’s a problem,” said Molly.
“I don’t have a hundred dollars to prevent my daughters from having incest babies,” said Derlores. “I have talked with them on more than one occasion about personal responsibility and that means they know what the consequences of such behavior can be.”
“Well, since it happened at my house, and since my daughter probably egged them on, I’ll take care of any expenses involved in giving Tasha and Keesha their options back.”
