The next week was a busy one in the household. The kids were home from their sleepover and seemed to be everywhere at once. Nikki had four days off from her job at the hospital. And everywhere I went, my mother-in-law was there. Every time I looked at her, I got hard remembering what we had done a few days ago. And I got plenty of chances to look.
I was mowing the lawn one afternoon. Karen decided that she needed to weed the garden wearing some tight denim shorts and a bikini top which barely held her large breasts in check. Every time I got near to my mother-in-law, she would make sure to bend over and point her butt at me. It was probably the worst mowing job I'd done since I was ten.
Then, I decided to make dinner one night. Stir fry, my specialty. Karen took it upon herself to taste test the meal. As I fed her a piece of vegetable from the skillet, she pressed close to me -- ostensibly so that nothing would fall on the floor. What happened was that by getting so close, she had her breasts pressed against my arm and side.
Of course, I got my own, sometimes. One morning, Karen was doing the dishes. The kitchen was momentarily empty, so I reached around my mother-in-law to wash my hands in the soapy water. I pressed my groin against her soft bottom. Karen was in a light summer dress that day, so I could really feel her butt. My cock grew hard and pressed between her cheeks, but Karen just ground her butt harder against me. Until we heard Nikki open the bedroom door, anyway (she'd been changing). I hurried to the bathroom to jack off, hoping my wife wouldn't notice my condition.
Saturday evening, Nikki left for work at the hospital and the kids were soon put to bed. Karen was nowhere to be seen, so I sat down on the sofa to watch some television alone.
A few minutes later my mother-in-law walked in wearing the shortest pink nightgown I'd ever seen on her. When she walked in front of me, I could see the bottom of the black panties she was wearing. And from the way they were bouncing, her large breasts were hanging free. Karen sat heavily on the lazyboy.
"Is this what we're watching," she asked, looking at the sitcom playing on the screen.
"Unless you want to change the channel," I told her and tossed the remote onto her lap. Karen picked it up and flipped to the adult pay-per-view channels. A couple minutes later, we were watching a long-haired blond bent over a chair and having her shaved pussy eaten from behind by a short-haired brunette with big tits.
"Ever done anything like that," I asked.
"You wish," Karen laughed.
"What I really wish is that you were over here on the couch with me," I told her. Karen made a big production of sighing and slowly making her way (with a bit more hip swish than usual, I noticed) to the couch, where she sat beside me to watch the girls on the television.
"I really put that on for you," she told me. "I figured you'd like it."
"Not like I really need it," I said with a quick glance at my crotch. Karen's eyes followed mine and locked onto where my erection was making a tent in my shorts. My mother-in-law undid my shorts, reached inside to pull out my dick, and slowly stroked it while we watched the television. I tried to return the favor, but I couldn't get my hand to her pussy without interfering with her stroking of my manhood, so I had to settle for playing with her tits and nipples through her nightgown. I even elicited a slight moan when I lightly twisted her nipple.
"This is getting to be too much," I told Karen after a several minutes. I'd been hard ever since Nikki had started getting ready for work figuring -- hoping -- that this would come to pass tonight, and the stimulation from her hand was getting to me. "If you keep it up, I'm going to cum."
"Will it stop you from fucking me later," my mother-in-law asked.
"It might slow things up a little bit," I told her without trying to sound too surprised by her choice of verbs. "But no, it won't stop me."
"Good answer," she said scooting her butt to the side before leaning down and engulfing my cock with her hot mouth. I only got to watch my manhood sliding between her lips for a couple minutes before I groaned loudly and unleashed a torrent of cum into her mouth. Karen swallowed it all and kept sucking until she couldn't keep me hard any more.
"You want to continue this out here," I asked, "or go to a room?"
"Might be better if we went to my room," she said. "Never know when a little one will get up to use the bathroom." So we turned off the television and held hands as we walked back the Karen's room.
Once inside her room, with the door shut and locked, I caught Karen up in an embrace and kissed her hard. She returned the kiss and added her tongue to the mix. I grabbed her soft round ass with both hands and pulled her groin hard against me, kneading her cheeks as we kissed.
