A Night of Discovery

... While she did that, her hand came up and began to caress his left nipple. He jerked and moaned aloud. "My God, I thought only girls had sensitive nipples. Wow, was I wrong." Susan's lips slid down Jim's body and her tongue began to explore his belly button while she continued to roll his nipple between her forefinger and thumb. She was only inches from the head of his dick. His hips began to pump and his penis moved up towards her lips and then away. Susan felt uncertain about what was happening, but she wanted to give Jim the same pleasure that he had just given her. When his penis was close to her mouth, she stuck out her tongue and licked the head. She followed him down, and as his hips pumped upward again, she took the head in her mouth. Jim moaned and held himself still for her. She tasted the saltiness of his pre-cum and was surprised to find that she liked the taste. She brought her hand down and began to stroke his shaft as she licked and sucked on the head. Jim was moving his hands over her shoulders, along her neck and through her hair. He held her hair in his hands and began to moan. Susan brought her other hand down and cupped his balls, squeezing gently. As she did, she took more of his shaft into her mouth.

Jim was hyperventilating and uncontrollably pumping his hips to match his stepsister's movements on his erection. Then, as his arousal began to peak, he pushed his finger into her. As it entered her, she began, suddenly, to orgasm. Jim froze, sucking in his breath. Then, she felt him convulse and begin pumping hot, wet sperm into her throat. Susan was so inflamed that she welcomed the flood of cum into her mouth. She gulped it down and felt distressed and disappointed as the stream diminished in intensity and volume. She consumed him, trying to find more, savoring every drop of his ejaculate. She moaned and caressed his balls. She sucked harder and slid her mouth up and down on him. But, the flow slowed and then stopped, and he began to soften in her mouth. Reluctantly, she let him drop away and moved up to rest her head on his heaving chest. They both rested quietly for a few moments, and then, Susan began to kiss her way from her stepbrother's chest to his neck, and then to his ear. She whispered to him, "I have a joint."
