Derrick pulled the car into the motel's parking lot. They had arrived at Corpus Christi at 4:30 P.M. It took them eight and half hours to get here from Dallas. Derrick looked over at his girlfriend sitting in the front seat aside of him. If all goes according to plan, this vacation will mark a new step in their relationship. He looked at his mother sitting in the backseat. Kathryn winked at him and blew him a kiss. Yes, he thought, it should be one helluva week.

Kathryn said to the two people in the front seat, "You stay in the car and I'll check into the motel. I need to stretch my legs after the long drive." Soon Kathryn came out, got in the car and told Derrick where their room was located. Within ten minutes, they had all their bags in the room. The room was not much to look at; it had two double beds, a small table placed in front of the balcony, which looked out on the Gulf.

"I know there isn't a whole lot of privacy, especially for two young people so in love as you two," said Janet to her son and girlfriend. "We'll work something out, I'll get scarce, when you want to get, err, intimate. Hey, who knows, I might get lucky too."

Derrick and Tiffany laughed at Kathryn's comment. "Mother, I know you won't get in our way," said Derrick. We should all have a good time here; there is plenty to do at the Gulf. I'm sure we can work something out." Tiffany nodded in agreement.

"What do you say we walk around the motel and see what is located close by," suggested Kathryn? "I haven't stayed in this part of the town before. We can walk on the beach and later find a place to eat."

"That sounds good," replied Derrick. "I need to get some exercise after that long trip cooped up in a car."

The three of them walked along the beach. The beach was empty; most people had gone back to change and get ready for supper. Derrick and Tiffany walked together, arm around each other's waist and bodies pressed tight together. Kathryn walked on one side of them. She felt left out, until Tiffany, holding out her free arm, said, "Come here Kathryn. I am so happy you have included me in your vacation. Thanks for that and everything else you've done for me." Kathryn slipped her arm around Tiffany's waist and linked the three of them together; Tiffany gave Kathryn a kiss on the cheek and pulled Kathryn tight against her body. That's they way they walked down the beech, three people joined together, enjoying each other's company.

Derrick saw two girls in sexy bathing suits and said, "Boy, look at those girls, they hardly leave anything to the imagination." Tiffany and Kathryn laughed at Derrick's remark "What's so funny," he asked.

"Oh, nothing," replied Tiffany. "But if you think those suits are revealing, wait until tomorrow. You ain't seen nothing yet."

Kathryn added, "Don't ask us about it, you'll just have to wait until tomorrow."

She and Tiffany broke away from Derrick and ran up the beach together, still arm in arm. Before Derrick reach them, Kathryn said to Tiffany, "When Derrick sees you in that suit, he'll jump you right there. I'll have to leave the room quick or get embarrassed." Again, they laughed at the comment.

After a long walk on the beach, they decided to go back to the room to shower and change for supper. As they arrived at the room, they realized they had a problem, privacy. "Should I go out on the balcony until you two have showered and dressed," asked Kathryn? Then, we can change places?"

Derrick spoke up, "That's going to be an on going problem, privacy." He turned to Tiffany and whispered something in her ear; she nodded her head in agreement with what he said. "Mother, when it was just you and me, we didn't worry about privacy; the only thing different is the presence of Tiffany. We cannot keep running out on the balcony every time we change. You and I do not mind and neither does Tiffany, so act like one big happy family for the week and do not worry about anyone getting embarrassed. If that's OK with you mother?"

"I'm fine with it. You know I am not a prude, never have been. Kathryn continued, "I will give you privacy when you want it. Now let's get ready for supper, who wants to shower first?'

"I'll go last, it will only take me about fifteen minutes to get ready," said Derrick. "Why don't you go first mother, Tiffany and I can use a little time alone." Therefore, Kathryn went to shower first, which left Tiffany and Derrick together. As soon as the bathroom door closed, Derrick and Tiffany embraced and kissed each other passionately. Derrick grabbed her tits and played with them.

"Derrick, you keep that up you'll make me get wet, save it for later," said Tiffany.

"OK Tiffany, how about a quick blow job?"

"Your mother could come out of the bathroom at any minute and catch us," replied a shocked Tiffany." We can't take the risk, wait until later."

"Tiffany, please, just a quick one," begged Derrick. "I'm so horny, it won't take long. Mother never takes a shower shorter than fifteen minutes; we still have almost ten minutes. Please!"

"OK, it's your mother. I do not know how I am talked into these things. Hurry up, get your shorts off, if you want that blow job."

With one quick motion, Derrick was naked from the waist down, sporting a hard on. Tiffany knelt in front of him and began sucking him off. She took as much of his hard cock in her mouth as she could. She did that for a couple of minutes, and then she held just the head of his cock in her mouth, while she jacked him off. In two minutes he came. He shot most of his hot come in her mouth and she was able to swallow it. Only the last shot hit her on the cheek. Just then, they heard the bathroom door open. Derrick pulled up his shorts and Tiffany stood up as Kathryn came out of the bathroom wrapped in a towel.

"Your turn, she said to Tiffany. Tiffany walked toward the bathroom. Kathryn stopped her, took a finger touched it to Tiffany's cheek and wiped off the drop of come. "You missed this," she said to Tiffany. Kathryn held out her finger, with the drop of come on it, to Tiffany. "Here, you don't want to waist it and stuck her finger into Tiffany's mouth. Tiffany turned bright red. Kathryn said to her, "Honey, if the situations were reversed, I would have done the same. If only I had known, I would have taken more time."

"Kathryn, you're the best," said Angie and she hugged Kathryn. Derrick is right; you are a very special mother." She hugged her again and whispered in her ear, "and a damn good pussy licker." Tiffany went into the bathroom and shut the door.

Derrick looked at his mother and said, "How about a quickie" and he dropped his shorts. He still had a hard on.

"Derrick, you're a mess," said Kathryn. "Tiffany just sucked you off and now you want to fuck me? Control that thing. What happens if we are caught? That would put a damper on the vacation, wouldn't it?

"Mother, I'm so horny being around the sexiest two ladies that I know. Tiffany won't be out for ten minutes, it won't take me that long."

"You better not make a mess. Here sit on that chair; I don't want to get sweated." With that, Kathryn opened her towel, spread her legs and sat down of her son's hard cock. She had to admit it felt good as she bounced up and down on Derrick's cock.

Soon, Derrick yelled, "I'm coming." Kathryn got off him and caught his hot load in a corner of the towel. Derrick pulled his shorts up and Kathryn wrapped the towel around her again. Soon, the bathroom door opened and out came Tiffany wrapped in a towel. "It's your turn," she said to Derrick.

When the bathroom door shut, Tiffany came over to Kathryn. "She put her arms around her neck and pulled Kathryn close to her in a warm embrace. She kissed Kathryn on the lips and her hand found the opening to Kathryn towel. Soon, Tiffany's hand was busy caressing Kathryn's tit. "I wanted to do that to you all day," said Tiffany. "Ever since last night, I've been thinking about what we did and what you said. You were right, when Derrick and I went to bed last night, we made love. It was good, like always, but different from what you did to me. I am not sure what I want. We had better get dressed, before Derrick gets out. He is so horny; he would probably jump both of us. You saw, he had to get relief while you were in the bathroom. I was almost afraid to leave you with him, when I showered."

Kathryn thought, If only you knew. "Tiffany, I'll try and give you two as much time alone as you want. I must say though, I would not mind some time alone with you. I've just started to show you the things one woman can do to another."

The two women had shed their towels and were just getting dressed, when the bathroom door opened. Kathryn and Tiffany had their backs to the door, so when Derrick emerged from the bathroom, all he saw was two women from behind. "Shit," said Derrick, "if I would have been a few seconds earlier, I would have seen you two nude."

"Derrick, you're such a shit," said Kathryn. "If you want to see me nude, here you go." Saying that she turned around, and she gave her son a view of her naked body. He had seen it many times before, but this was the first time, there was another person in the room.

"Here Derrick, get your jollies," said Tiffany. She also turned around. "Well, there you go, now you won't have to peek at us."

"Derrick, looked at his mother and then at Tiffany. "I'm looking at two of the sexiest women in the world..."

Tiffany looked at Derrick, then at Kathryn and said, "Hey, big boy, why do you still have the towel wrapped around you, afraid to be seen by your mother."

"No," said a startled Derrick. Tiffany was starting to get bold. This may be easier than he thought. "Here, you go ladies," and Derrick removed his towel. After seeing both of his lovers nude, he had a hard on, of course.

Kathryn was the first to speak. Looking at her son, she said, "Well I can see he really is my big boy." They all laughed at that comment. "Seriously, I'm glad this happened, this way we won't be worried about being embarrassed, staying in the same room. We will not have to worry about it any more. Let's get dressed, I'm starved."

The person at the desk in the motel told them of a good seafood restaurant. It was so close to the motel, they could even walk there. They only had to wait about thirty minutes for a table, not bad for spring break in Corpus Christi. The food was good and everybody enjoyed his or her meal. It was only nine when they got out of the restaurant, so they decided to take in some of the nightlife.

They had seen a few good looking bars on the way to the restaurant. "Let's take the one farthest away from the motel and work our way back," said Kathryn. "That way, the last bar we go to will be the one closest to our motel and we won't have to stagger too far to get to our room."

Tiffany and Derrick both laughed at Kathryn's remark.

After three or four hours and five or six bars later, they decided to call it a night. Tiffany was the worst one of the three; she could stand up and walk, just not too straight. So the three of them walked arm in arm, the two blocks to their hotel. Tiffany was in the middle of Kathryn and Derrick, that way they could steady her. As they walked, Kathryn allowed her hand that was around Tiffany's waist to slide downward so it was grabbing her butt, Derrick followed suit. Soon they were both grabbing and massaging Tiffany's ass. It was beginning to have an affect on her.

"Oh I love the both of you," Tiffany said, and hugged both of them tighter. She turned her head toward Derrick, wanting a kiss. Derrick responded by kissing her hard on the lips and driving his tongue quickly into her mouth. The kiss only lasted for a few seconds but it got Tiffany turned on. She tilted her head toward Kathryn, slid her hand up Kathryn' back until it touched the back of her head and pulled Kathryn' head toward hers. When their lips met, Tiffany took the initiative and drove her tongue deep into Kathryn' mouth. "God, I'm turned on," said a hot and horn Tiffany. "Are we almost at the motel?"

Mother and son looked at each other and both thought this was going to be easier than they had imagined. "Here our hotel," answered Derrick. The three of them quickly made their way up to their room and went inside.

Tiffany was the first to speak, "I know this sounds kinky and weird and maybe it's the booze, but I want both of you. My pussy is on fire, just from the walk home and having your arms around me. If you don't want to do it I'll understand, but I really want to feel both of you, together, making love to me." Tiffany lay down in the middle of the bed and waited.

Kathryn and Derrick smiled at each other and took their positions on either side of Tiffany. Kathryn began to kiss Tiffany a hard, firm, open-mouthed kiss, while her son watched. When she was finished, Derrick kissed Tiffany while his mother watched. Then they both kissed her at the same time. Three sets of lips were touching each other, three tongues intertwined. After a few minutes, Tiffany pulled back and watched Derrick and his mother kiss.

"Wow," exclaimed Tiffany. "That's erotic, mother and son kissing like that, and I'm turned on even more. I want more," and pulled both their heads toward her...

Kathryn and Derrick turned their attention toward Tiffany. If this threesome was going to happen and continue to happen, they had to make sure Tiffany had some of the best sex she ever experienced. Derrick moved his lips down Tiffany's neck, while Kathryn returned to Tiffany's lips. While his mother was kissing his girlfriend, Derrick nibbled on Tiffany's earlobe, knowing exactly what to do to get her hot and bothered.

Kathryn could feel how much Tiffany was being turned on by her son's attention, she began to unbutton Tiffany's blouse. She undid her bra, releasing those beautiful breasts she had enjoyed so much just yesterday. Her son saw what she had done and helped her remove Tiffany's blouse and bra. Tiffany was now naked to the waist.

Together they both moved their attention downward toward Tiffany's tits. They both kissed all around the breast that was in front of the. Tiffany's breath was getting deeper and more rapid. When they finally got to Tiffany's nipples, they rock hard. As they both sucked and nibbled on her nipples, Tiffany began to moan and her hips were moving upward, thrusting her ass off the bed. Kathryn moved her free hand down between the young girl's legs and rubbed her pussy through her shorts. Even with fabric separating her fingers from Tiffany's pussy, Kathryn could feel how wet it was. That did it; Tiffany had her first orgasm of the evening. Tiffany's hips bucked up against Kathryn's fingers, a low moan or groan escaped from her throat, her head flew back against the pillow and she grabbed the back of Derrick's and Kathryn's heads and mashed them against her boobs.

The whole episode tended to make everyone more alert and ready to have more fun.

"That was unbelievable," said Tiffany. "I didn't think I could come that hard and still have my pants on. That was so wild, having the three of us sharing a kiss and then seeing the two of you kiss like that." She said to Derrick and Kathryn. I want to see and experience more. I want to feel Derrick in me, while you and I make out," Tiffany said to Kathryn. "I hope that doesn't freak you out?"
