[MF] My (32) fiancé’s hot sister (29) I got to see her naked and it wasn’t the last time. (Part 4)

So the final part, I don’t know what will happen after this, I will have to wait until we see each other again.

So this was only in September this year, it’s my birthday so Beth had decided to come to a little house party we was having, just a few friends and family.

My birthday landed on a Tuesday this year so we decided to have it a few days before, Beth came Friday night with the party being Saturday, Friday was chill, talking about the party, things we needed to go get (alcohol, food) we talked about plans for the day, and Jess told Beth she needed to go get her hair and make up done in the afternoon and asked if she wanted to try book Beth in at the same time, Beth declined and said it was ok, she would stay behind and help me set the house up, she doesn’t wear much make up and her hair looked great, I think Jess asked to be polite, we mention getting drinks ready sorting some snacks, the usual party prep! Jess was happy as she didn’t want to start doing all this with nice fresh hair and makeup.

We spend the night chatting and having a few drinks, nothing crazy because we didn’t want to be hungover for the Saturday, general chat, until the conversation became about sex, Beth telling us it had been a while for her. Jess seeming to boast a little about our sex, a bit of context, me and Jess have a very healthy sex life, quite often and both are very adventurous, I’ve even shared Jess with my best friend, tried a lot of things in the bedroom so we are both confident it talking about it.

Jess decided to share quite a few things about our sex, about how she was surprised when we first had sex, and more so the more we had sex, she basically told her because I was quite a shy person, abit of a gentleman, she didn’t expect how adventurous and dominant I can be, or she was surprised about my size, now I know I’m not the biggest, about 7” maybe 7 and half in a strong day, average girth but I think her previous partners where on the small side, but also I have a slight upwards bend, which from my previous and current partner seems to be liked and complimented a lot.

Anyway this was such a turn on, not only the sex talk and ego boosting compliments, but knowing Beth has had her lips and hands around my cock and even a little tease in her pussy, it made the conversation seem much more thrilling.

It was time for bed, beth said she was going to take a shower (the main bathroom back in action) me and Jess where quite horny by this point so quickly went to bed, hearing the shower turn on and door shut, we started passionately kissing and touching each other, we both got naked and I soon got between her legs and made my way to her beautiful pussy, always a guarantee to make her cum, it wasn’t long until she was cuming, her moans covered by her hand, jess Was trying to keep the noise down, I soon finished her off and couldn’t wait to put my rock hard cock inside her, I jump up beside her and put her in the spooning position, a bit of a favourite of ours, I slide my cock inside, she moans, I’m so horny by this point, As I’m getting more and more into it I forget about Jess just next door, my moans getting loader, Jess even more so, it didn’t seem long before we hear a bit of squeal and the shower turn off.

We come to a stop wondering what had happened, then the bathroom door opens, we quickly pull the covers over us, still inside her, Beth knocks on the door, we both freeze in a panic, “yes” Jess shouts, Beth replies “sorry do you mind if I use your shower the light bulb has blown, “erm yea sure” jess replies, we just lay there, my hard dick still inside her, Beth walking through in just a towel “aww look at you two having a spoon” said Beth, me and Jess smile, trying are best not to laugh. Beth walks through and closes the door, this time remembering to lock it.

The thought of Beth in the shower, really got me going, I started to drive my dick back into jess, she whispers “wait, Beth is in there” as she tries to pull away, I was way to horny to stop, I grab her by the hips and pull her hard onto my cock, a loud moan from Jess “stop it” she says, I couldn’t, I slowly start to rock her against my cock, she gives in, we just keep fucking, not long later we hear the shower turn off, and the door open, again we freeze and act like we are just cuddling, the door opens and Beth pops her head around the corner, “where are the towels”, we forgot to put some out as we wasn’t expecting guests to use it, we tell her where they are and she walks back in not closing the door, I can’t help but my eyes go straight to the mirror that faces the door, I see Beth’s beautiful ass walking away to find the towels, I nearly blow my load there and then, I slowly start sliding my cock in and out of Jess’s wet pussy, she slaps my arm to try to stop me, I can’t stop, I look at the mirror again and see Beth stood facing the mirror through the door, her wet glistening body, perfect perky tits, I keep fucking Jess while my eyes are fixated on Beth, she looks looks straight at me, I just keep sliding in and out of Jess, Beth stood there naked watching, we are still covered but she knows what we are doing, it sent me over the edge, I couldn’t hold it back any more my cock throbs my hips thrust forward, I stare at Beth through the mirror and I cum inside Jess, I try to hold back my moans as I drain myself inside her, another look towards Beth and she just smiles, pulls a towel over herself and walks toward the door, she walks through the room and says “thank you” and shuts the door behind her.

Jess slaps my arm again, “she could of seen us” “sorry I was to horny to wait” i reply, we both laugh and decide to go clean up, I tell Jess I’ll use the main bathroom and change the light bulb while I’m there, Jess agrees and heads into the en-suit.

Now this is where I realised what had really happened, i go grab a new bulb and I walk to the bathroom, I head toward the switch and see it’s in the off position, I like to make sure it’s on so when I screw in the new bulb so I’m not sat in the dark, I switch it on and to my surprise the light turns on, I stand there in confusion but soon I started to think about what had just happened.

I didn’t know if I was right but I think Beth just lied, I think she needed an excuse to use our shower, I think it was all part of her plan, now I knew she didn’t know we having sex, but maybe she wanted to let me see her naked again, maybe she thought she could catch us, or maybe got abit more than she bargained for and used it to her advantage.

I quickly head to the bin to throw a perfectly good new bulb away, I head to our bedroom and Jess asks if it was all sorted, I couldn’t tell her it was working, so I just played along and told her I got it switched out!

For the next half an hour it’s all I thought about, i was sure she just created that whole scenario.

This is already quite long and have to get back to work, so I’ll update on the rest of the weekend soon.

Was I right? Did she do it on purpose?
