So my girlfriend at the time (about a year ago) had to move in with her mother who was sick, she moved in to take care of her and her adult daughter moved in with her as well because she had just broken up with her boyfriend whom she was basically living with. My girlfriend was super cute, dyed her hair dark red and cut short had a lip and tounge piercing big beautiful tits and a tight body (she worked out alot) she was always self conscious about the scar on her tummy from having a c-section from her daughter but I said it just made her hotter. I would always go over to her place bacause she couldn't leave her mom by herself, so I usually stayed over for 2 or 3 days (she lived about an hour hour away and it was just easier for me to stay over for a few nights) Her mom didn't care because she liked me so it all worked out.
So the weird thing was that they didn't have a TV in their living room, so if we wanted to watch a movie or a show we had to do in her bedroom which I didn't mind because it was a bit more..intimate.
So one night we decided to watch all of the Lord of the Rings movies, so we got in her bed, cuddled up and started the first movie. About half way in, her daughter came in her room (she had her own seperate bedroom) and asked if she could watch with us because she was bored. My girlfriend said fine, but there wasn't really anywhere for her to sit so she got a blanket and a pillow and just laid out on the floor beside the bed (the bed was against the wall sideways and the TV was on the left hand side) So me and and girlfriend were spooning while watching the movie, I had my arm around her waist, she was the little spoon of course.
So we got to the second movie in the trilogy and we started to get a little frisky. I started to kiss her neck and nibble her ear and she started to grind her butt against my dick which started to get me hard. She looked down at her daughter on the floor and she had fallen asleep, so we took the opportunity to go further, trying to be as quiet as possible. I slid off my boxers and she started to rub my cock from behind her as I slid my hand down her panties (she was just wearing panties and a shirt) and began to rub her (now very) wet pussy. I slid a finger inside her and she let out a low quiet moan as I started to finger her. By this time my cock was hard as a rock and dripping precum. She keeps looking down to make sure her daughter didn't wake up (which it didn't seem like it) so we kept going. Finally she grabs my cock and places it against her warm wet hole and I start to slowly push inside her. She was still on her side and I was behind her so she felt extra tight because her legs were closed. We both let out a moan/sigh as I pushed my full length inside her, she felt so damn good.
So I start slowly fucking her with long deep stokes because we didn't want to make alot of noise, when we usually fuck it's fast and hard, but obviously we couldn't do that this time. But this time it felt amazing, just going slow and deep, it was much more sensual, especially when we're trying to not make much noise. At some point we roll over so I'm on top of her missionary and fucking her slow and deep and looking into eyes and kissing her deeply. After a few minutes of that she starts to have and orgasm, but tries really hard not to make any noise, unfortunately a few involuntary grunts did come out, but not too bad... Or so I thought.
Since I was now on top of her, I looked over at her daughter to make sure she wasn't awake but..... She was...and looking right at me. I froze and started to panic, but she wasn't saying anything, just watching. We had a blanket over us so she couldn't really see anything but obviously she knew what we were doing lol. I decided not to say anything to my girlfriend because she would just want to stop and I need to nut badly. I picked up the pace and fucked her a little harder and faster, she was breathing heavily but still trying to keep quiet. After a couple of minutes I felt that familiar pressure in my balls and pushed deep inside her and shot a massive load inside her making a loud grunting noise. I looked over at her daughter again and she had her eyes closed, but obviously she heard me nutting in her mom lol.
Went I shot my last rope in her, I took off my shirt so she could have something to catch the cum since she didn't want it all on her bed. Good thing too because when I pulled out a huge glob of cum just poured out of her and onto my shirt (I was sort of proud lol) I rolled over and she got out of bed to go to the bathroom to deal wirh the aftermath of my huge load dripping out of her. I looked down at her daughter who, once again, was looking at me with an actual smile on her face.. I had no idea what to make of that. Afterwards, she never brought it up, neither did I, and my girlfriend never knew that her daughter watched her mom get a creampie. It was definitely an interesting night.
