When a hard cock pushes against a pussy or an ass hole which is covered by underwear or thin clothes such as yoga pants or a silky dress, sometimes a large enough cock will ever so slowly begin to win over the fabric. The cock pushes the fabric into the orifice, pulling the cloth with it as it enters. The cloth will wrap around the cock like a makeshift condom, and struggle to push it out again. As the cloth moves both participants of sex can feel it, the male can feel it straining against his penis and the woman can feel the cloth drag and rub against her clit in a pleasurable way. In these situations often the cock and the clothes play an erotic back and forth, where the dick will slip in just a little bit only to be repelled by the stretchy fabric. Moments later the dick will slip in again, a tiny little bit deeper this time, only to be pulled out again. This repeats over and over, causing the penetration to be slow and teasing as the penis buries itself deeper and deeper and deeper into the defended orifice over many cycles. This teases and edges both participants of the sex immensely.
