"You usually find that the first incestuous session between a mother and her teenage son is spontaneous. Although one or (usually) both have fantasised about such a relationship and perhaps innuendos have been made, that first act will take them like an express train and they won't know what's happening. In peter's case, he was simply walking around the empty house with an erection when his mother suddenly entered through the back door. Seeing his erection and aware of the fact that he couldn't exit the kitchen without passing close to her, she said, "Nice cock. I might have to help you with that". The kitchen table was beside Peter and Sue, being quite energetic, lifted her son and sat him on the edge. As she did so, his erect cock travelled up the line of her thighs and pressed in the material of her dress, just where it shouldn't have, causing Sue to moisten quickly. It was only a blowjob that afternoon, but having discussed it with him the following day, something similar happened in her bedroom, ending in Sue taking her son's virginity and confirming their incestuous relationship."
