How far is too far? Cheating with my wife’s sister [MF]

I kneeled, my dick positioned in front of her slightly open pussy lips, ready to explode. She furiously rubbed her clit with one hand, the other holding her up on her hands and knees, bent over in front of me.

This happened about two years ago now. My wife and I had been married about four years, and were 26 years old. We were both doing well in our careers, and had a large house, and no children yet. My wife, Victoria, has a big family and a sister who’d been having trouble in her own marriage. Julie had been with her husband for two or three years, was 32 years old, and recently found out that he was cheating on her with a coworker and had cheated previously with a stranger. Their marriage had pretty much fallen apart, but Julie was about five months pregnant with their first child.

During their divorce, we all agreed it’d be best if Julie came to live with me and Victoria. We had two open rooms, and plenty of space for the three of us. She moved in, and things went well.

One evening, probably three weeks into her living with us, we were all getting ready for bed. Victoria was upstairs, and I was grabbing water and shutting off the lights. Julie was still in the living room watching TV, so I stopped to say goodnight. We got to talking for a little while about the show she was watching (Planet Earth or something similar), and I sat down for a few minutes on the couch with her. She had on her usual tank top and pajama shorts, made of a soft blue cotton material. I noticed her slight bump under her shirt, and how her tits had grown with her pregnancy.

To give you an idea of how we look, Julie is about 5’5” and 120 pounds normally. She has blonde hair, she’s thin but with slight curves – not a big ass but it’s round, and her tits are usually B cups. Now, they were probably solid C or small D cups. She kind of looks like [Alison Brie](https://m.imgur.com/r/AlisonBrie/pwVrTab) but with slightly blonde hair. I’m 5’11”, about 170 pounds and an average and slightly athletic build. Brown short hair, fair skin, nothing special.

We talked for a few more minutes and then I went up to bed, and she stayed downstairs to watch TV a bit longer. Julie’s room was upstairs as well, but she worked in the afternoons so she’d regularly stay up later.

Three days or so later, we were going through the same routine. I was upstairs with Victoria, who’d fallen asleep. I fell asleep not long after, with the TV on. I woke up an hour or so later and went downstairs to get water (this is pretty regular for me, I often have trouble sleeping), and noticed Julie watching TV again. I sat down with her again, and we talked for a bit about her husband, the pregnancy, and work and life in general. She was in a tank top again, her legs covered by a throw blanket. She was laying on her side, facing the TV, legs toward me, while I sat upright.

We kept talking and got to the subject of the pregnancy, and she mentioned she’d felt the baby kick and move around. “Do you want to feel it?!” she asked sort of excitedly. I said sure, and she shifted onto her back, and pulled the blanket down and her shirt up slightly, revealing her small bump and her belly button. At this point I noticed that she wasn’t wearing her usual shorts or pajama pants – instead she just had a pair of green lace panties on that I could see the edge of under the blanket. She grabbed my hand, her warm fingers wrapping around mine, and placed it just below her belly button. I could feel the warmth of her skin, from both her stomach and her hand pressed against mine.

She paused for several seconds, and moved our hands in quick motions, trying to follow the movement so I could feel it. “Do you feel it?” she asked, and I responded “No, sorry.” She pushed my hand further down with hers, and I could feel my palm resting half on her underwear, half on her skin. She was breathing heavier, and looked at me, staring like she was concentrating. I gently pulled my hand away, not wanting to make her uncomfortable, and I could feel myself getting aroused and felt a little guilty about it.

Julie leaned back towards me, grabbing my hand, and said “here,” and pushed her panties downward with her other hand, and placed mine firmly on her bare skin, just above her covered pussy. As she placed it and moved her other hand, I could feel her panties push up against my hand that had displaced them. Her skin had a very thin layer of hair, like she had shaved within the last week, but it wasn’t prickly. I could feel the warmth of her body radiating into my palm and fingers. I was laying on my side now, my right hand on her body, the left arm propping me up next to her. Her shirt was still up over her belly, and I could make out the underside of her tits near my face as well.

At this point, I’d gotten noticeably harder, my cock pressing against my sweatpants and pushing gently against her right leg. Her breathing deepened, and I could sense her arousal, which became even more obvious when she pushed my hand lower, my pinky finger now inside her panties and resting against the outside of her pussy lips.

I had to pull myself away and say goodnight, walking away and trying to hide my clear-as-day cock standing at full mast. Julie sighed gently and we both went to sleep. The next day came and there was a bit of tension between us, but nothing that Victoria noticed, as far as I was aware. That evening, I purposely waited until she fell asleep again before going back downstairs to sit with Julie again.

This got longer than I thought it would, so I’m finishing up part 2 and will post it if people are into it!
