Han bjuder in mig på en drink utan att veta vad jag har på under

He sees me in the distance and comes over to buy you a drink at the bar, not knowing that underneath and inside me I had my vibrating toy in sound detector mode, it vibrated with the music and I tried to contain myself but I couldn't take it anymore and I asked him to let me suck his dick in the middle of the conversation and we ended up fucking delicious on the bar chairs
