While I was going to college in Montana, Kathy delivered our second daughter. She had had a difficult pregnancy, so her mother and youngest sister, Sue, who was then estranged from her husband, arrived a week or so before Kathy went to the hospital and stayed with us until Kathy was back on her feet.
Maud, Kathy's mother, had to return to Shelby (a distance of about 200 miles) to perform some errand -- and was gone two nights while Kathy was in the hospital. Sue remained behind to cook for me and help get the house ready for Kathy's return.
Sue, at 19, was a very attractive girl with a beautiful hourglass figure. After mom left for Shelby, Sue decided the house was too warm for all those pesky clothes, and the next thing I knew, she was parading around the house clad only in her bra and a tiny pair of cutoff shorts, her long, slender legs seemingly going up to her shoulders.
After supper, we played cards for a short time in the kitchen, but I had to study, so I moved into the living room and opened my agronomy book. I've never had a keen interest in soil management, and consequently, I had difficulty concentrating, especially after Sue returned to the living room and sprawled full length on the couch.
Somewhat to my chagrin, she was studying a copy of "Playboy" I had hidden in our bedroom. Her legs were carelessly spread, one extending full length on the couch toward me, while her other foot rested on the floor.
At first, I had noticed only the magazine she held in her hands that concealed her face, but then, since she couldn't see me, I stopped to openly admire her bra covered breasts. While I was studying her figure, she absently reached down to adjust her shorts. Her shorts had baggy legs, and the adjustment resulted in opening one leg so her dark delta was clearly in view.
Although I felt my cock twitch in response, I was sure her flashing was accidental. A few minutes later, she sat up and hooked her thumbs under her brassiere cups. "This thing is getting uncomfortable. Would you mind if I took it off?"
"I'd like you to take it off," I said without thinking. I tried to recover. "I mean I don't want you to be uncomfortable."
"But it looks like it's making you uncomfortable," she said, looking pointedly at my crotch which was now concealed under my textbook. I couldn't think of anything clever to say, so I just grinned and watched her reach behind and unhook her bra. Then she hunched her shoulders forward, letting the straps fall off her shoulders. Watching me, she held the bra cups in place for a moment or two, then lifted them away, letting her breasts bounce free. She dropped her bra in her lap and massaged her breasts, especially rubbing the reddened places where the bra had chafed under her breasts and on her ribs.
I don't know if I have ever seen anything as erotic as the way she rubbed her breasts. I was openly staring like a teen age boy, of course, wondering where this was going to lead us.
She seemed unperturbed by my attention. "Ah," she sighed. "That feels a lot better."
Her breasts were firm, but almost as large as Kathy's so they quivered as if they were molded from jelly whenever she moved. Her nipples were clearly engorged, and I wondered if she was going to play with them next.
Meanwhile, my cock was trying to lift the heavy textbook, and I longed to begin stroking it.
"It must be tough," she said in an offhand manner, "for a man -- especially a virile young man like you to have to go without when your wife is near the end of her pregnancy."
Jesus Christ! There was no mistaking the open invitation. "Would you like me to help rub some of those red spots?" I asked while inwardly wondering where I had found the necessary courage to proposition her.
"That would be nice," she said. "I can't reach where the clasp was rubbing my back." She rolled over on her stomach. Relieved that she couldn't see my erection, I moved to the couch and sat gingerly on the edge against her hip.
The bra strap had left marks on her back. I gently began massaging those reddened places. It seems I'm always surprised by how soft and warm female skin is. Sue was no exception.
The gentle rubbing soon expanded both in area and intensity, and I was massaging the muscles in her shoulders and neck, down her back to the edge of her cut-offs and back up her sides. My fingers briefly found the soft sides of her flattened breasts and moved on to her shoulders again. Again I worked down to her waist.
"Wait a minute," she said as she lifted her hips and unbuttoned the waist band of her shorts. "Don't pull them down too far," she said, "but this feels so good, I want you to rub my lower back, too."
I slid my hands under her waistband and continued manipulating her muscles.
"Further down," she said in a muffled voice. Soon I had both hands strongly working her ass cheeks; first one side, then the other. Then I touched the backs of her thighs only a couple of inches below her pussy.
Suddenly, she stiffened. The muscles I had spent nearly an hour relaxing were knotted in spasms. Her whole body vibrated and shuddered. Abruptly she rolled over, and pulled me down, holding me in a tight embrace while she kissed my mouth. "God, that was good!" she said. "It's been so long since I had a good cum!"
Then she added, "Don't you think you're a little overdressed, too?" Now it was her turn to stare while I quickly undressed. My cock has never been longer or harder than it was at that moment. Sue reached out and gently wrapped her hand around it.
"It's so soft and hard and hot. It's been months since I've held a cock and never one as beautiful as yours." Then she added, "While I play with it, I want you to play with my titties."
