I (m 23) live with my fiancé (f 23)in our apartment. It is fairly sized, with everything on the same level. My fiancé and I had our best couple friends over for the weekend (same ages as us). The girls decided to go out into town while I stayed at the apartment with my mate. Little did I know that the girls had planned to head straight for the local sex shop to get some supplies. While they were out, my mate needed to drive home to get overnight things so that they could stay over. I guessed that my fiancé had convinced them to stay over for drinks and games. While he was out, the girls both returned and were all giddy and giggling from their shop. I realised something was up, so I asked them what they had been up to. I was simply met with a dismissive but playful reply, while my fiancé game me a knowing look. At this point, I knew that she had something in store for me later on and the thoughts had me riled up. My fiancé is rather kinky, so there could have been all sorts of things in that shopping bag. They went into the bedroom and shut the door, sniggering as they went. More and more racy thoughts invaded my mind. Did they get some new underwear? New toys? Either way, I shifted my semi around my jeans to get more comfortable, but that only made things worse.
