Over the few weeks I continued giving Bobby his "lessons". He was getting stronger physically and more skilled as a lover. When we fucked he'd wait patiently for me to tell him when to cum. He could go an hour if necessary, although I didn't usually make him wait that long. His oral skills were excellent as well. I would miss these lessons once he was at Stanford.
It was Friday night and the phone rang. It was my sister Eileen from Chicago. "Eileen, how are you!", I said. It was great to hear from her as she had been away for the last few weeks.
"I need a favor.", Eileen responded. "Nancy has screwed up her housing request at college and has no place to stay. Would you be able to let her stay with you until we straighten it out."
Nancy was Eileen's stepdaughter. I hadn't seen her in a year, but she was a petite red head and quite pretty.
"Of course.", I replied, "I've got plenty of room here. When is she coming?"
"Tomorrow if you can handle it.", said Eileen. "You're a dear."
Despite the potential to complicate things with Bobby, I felt compelled to help out. Nancy was starting at The University of Houston, so it would be convenient for her to be here, as we were in walking distance of the school.
Bobby was getting ready to go to a ball game with the guys, so I needed to catch him before he left.
"Bobby, you remember Nancy, my sister Eileen's stepdaughter, don't you."
"Sure. She was real pretty, but a little strange.", he replied.
"Well, she's going to be staying with us for a little while until she can get her own place at the University. We'll need to be discreet about our relationship. O.K.", I said, "I wouldn't want my sister to know what we are doing."
"No problem.", he said, breezing out the door.
I picked Nancy up at the airport the next afternoon. I didn't remember her breasts being as large as they apparently were, but she looked otherwise as I last saw her. She was going to be a premed student.
We made small talk on the way home.
"So Nancy, did you have to leave a boyfriend back in Chicago?", I asked.
"No.", she replied, "I'm gay. I left a few girlfriends, though."
I tried not to appear too surprised. Eileen had given me no indication that Nancy was gay.
"In case you are wondering, mom doesn't know." she added, "I'm telling you because you'd figure it out anyway."
"Are you sure you are gay, Nancy? Have you had any experience with men?"
"I made it with a couple of guys, but they would cum so quick that I didn't enjoy it. Girls take their time.", she said.
We arrived at home in short order. I showed her to her room and left her to unpack. Bobby was out with friends. She hadn't been shy about telling me her sexual persuasion. I had sensed something different about her over the last few years, but couldn't put my finger on it. She seemed to look at me with a special look, one I couldn't quite understand.
"Is it OK to use the pool?", Nancy said, having finished unpacking.
"Sure.", I replied, "I think I'll join you. Houston is so hot."
We soon found ourselves standing next to one another in the pool.
My bikini tops were a little on the small side since I was still nursing, and this one didn't leave much to the imagination. Nancy's was on the small side as well, giving me a good view of her incredible petite body.
"So, Brenda, have you ever been with a woman?", Nancy teased.
"Not since I was in high school. Girls are nice but there is no substitute for a man.", I replied.
"Are you still nursing?", Nancy asked.
"Yes.", I'm a believer in breast feeding.", I replied.
"I thought so. You always had great tits, but now they are huge.", Nancy said, eyeing them intently.
Nancy suddenly reached out and boldly fondled my left breast. I was frozen in place, not expecting her action.
"Awesome.", she said, "You've got the most awesome tits."
I was speechless. She then reached around and undid my bikini top spilling my breasts out into the bright sunlight. In a flash her mouth was on my nipple.
I let her suck it for a minute, experiencing a mixture of surprise and arousal. I let her continue.
"Let's go inside.", Nancy said, "I want more of this."
We went into my bedroom and stripped off our suits.
Nancy was on top of me right away, sucking first one breast and then the other.
"I give great head.", she said.
Her face was soon buried in my pussy, and I was getting wetter by the minute. In ten minute she had me cumming, her face covered with my juices. She then sat on my face and I began to return her favors.
As the minutes passes we continued to exchange pleasures.
"We need to stop!", I panted, "Bobby will be home soon."
We dried off and sat at the kitchen table. I made a pot of coffee.
"I'm going to like it here, Brenda.", Nancy said. "I screwed up my housing request on purpose."
"Oh.", I responded.
"Yes. I've wanted you since I had my first period."
"I still think you should get more experience with men before deciding your sexual orientation. "You're only 18.", I replied.
"I'm not attracted to older men, and the young ones don't know what they are doing or don't care.", she said, "Where do I find a guy my age that really knows how to fuck."
Bobby came in wiping the sweat from his brow.
"God it's hot out there", he said.
"Bobby, you remember Nancy, don't you?" I asked.
"Sure. I understand you are going to stay awhile.", he replied, reaching out and shaking Nancy's hand. "I hope you like it here."
"I'm sure I will.", she responded, seductively. "I'm sure I will."
Bobby went to his room to shower before dinner.
"I don't remember him looking that good.", Nancy whispered to me.
"Well he's only going to be here for another month before going to Stamford, so don't drag your feet...", I encouraged.
"Does he have a girlfriend?", Nancy inquired.
"No. "He's fair game.", I responded. "You could do a lot worse."
"I'm going to take a shower, too, and get rid of the chlorine.", Nancy said.
She went to her bedroom. I went to Bobby's room immediately. He was just getting out of the shower. I took a bath towel and began to dry him off as he ogled my tits that were almost falling out of my bikini top.
"I need a favor, Bobby.", I implored.
"Sure." He said, his cock getting hard as I brushed up against him with my tits.
"Nancy thinks she's gay because she's never been with a guy that knows how to please her. She's so pretty they all cum right away and she never gets off. I'd like you to fuck her and not cum until she does. I'm sure she'll realize she's been wrong about sex with guys.", I said.
I knelt down and popped off my top, taking his now hard cock between my tits. Milk was oozing out as I fucked him with my tits.
"This is a quickie, so cum right away.", I instructed. In a couple of minutes he popped, spaying white goo all over my tits. "So, will you do me this favor, Bobby?'
"Yes.", he stammered. "How do you know she'll want to do it with me?"
"Trust me. She wants you.", I replied. "We'll have some wine with dinner, then the three of us will go skinny dipping in the pool. Just make sure she cums before you. OK?"
