Idea

A couple, hetero, homo, whatever, gets frisky and buys a pack of “gimmick” condoms that have pictures tiled on them. The first one they use is branded with images of a water drop, and their session goes perfectly smoothe. The next one has a ‘+’ symbol on it, and the receiving partner swears that the other feels larger than normal, though upon inspection, there’s clearly nothing out of the ordinary. Next, one that appears to be covered in images of tentacles. The two become overly stimulated by a mysterious writhing/crawling feeling, write it off as just being too pent up. The last condom in the pack is branded with the image of a bicycle pump. With each thrust a light ‘hiss’ fills the air, the receiving partner blowing up little by little. They grow tight, up to the edge of exploding, when the ‘giving’ partner cums hard, breaking the condom. Up to you as to what happens as a result.
