Susan Chalmers walked down the hallway to her bedroom, her parents were in bed already, they had to get up early. She paused at their door and heard the soft snores of her Dad. She peeked in, to say goodnight to her Mom if she was awake, but her Mom was asleep too. Her Mom was asleep on her side, facing the door. Her parents liked to sleep naked, and tonight was no different. The sheet had been pushed down to her waist, and Susan could see her Mom's breasts, still a firm and full 38D at age 40.
Susan and her sister Lisa had both inherited Mom's tit gene, her sister was a firm 38B, and Susan was a firm 36D. Thanks, Mom, she thought. The thought that her parents still loved each other, and still had a great sex life (she had heard them several times), gave Susan a warm glow. So many of her friends lived in single-parent, divorced households, and she had seen the difficulties they had endured. She closed the door gently and went to her room. Susan entered her room, and stripped off her clothes, she was so tired. After brushing her teeth and removing her makeup she crawled into bed.
She wished her sister Lisa was here, and not away at college, so she could have a late night gab session, and tell her all about what was going on in each other's lives. Thinking of her sister gave her a major tug of pleasure in her pussy, Lisa had taught her how to masturbate, and it had been one of the best things she had ever been taught. The remembrance of the pleasure washed over her, and she cast her mind back to that night a year ago....
Susan and Lisa had been alone for the weekend, Lisa was 19 and Susan was 18, and their parents had trusted them to look after the house since they were both responsible teens. Susan's best friend Maddie Krause lived next door, and Susan had been next door, swimming in their pool. Having her best friend and a swimming pool right next door was such a wonderful thing. They swam and splashed each other, laughing and enjoying the warm summer night.
At 11 PM, Maddie's Mom called Maddie to come inside. Maddie and Susan had said goodnight, and Susan had entered her house. She went downstairs, stripped off her bathing suit, and hung it over the drying rack. She went upstairs, with her towel wrapped around her waist, and she stopped at her sister's door. It sounded like Lisa was in pain, she was groaning.
Susan opened the door and was about to call out, "Lisa, what's wrong?" when the words died before she could utter them. By the light of a single candle on the nightstand, Lisa was lying on her back, her legs spread, and her hands playing with herself. She had 3 fingers of one hand pumping in and out of her pussy, they were making wet sucking noises. Her other hand was playing with her clit, her face was contorted, and her breath coming in sharp little gasps.
Susan stood rooted to the spot, her pussy heating up furiously. She could feel her pussy becoming drenched as she stared, fascinated, at her sister. Her tits became rock-hard cogs, tingling like mad. She knew about masturbation, she had done enough fingering of herself in the dark to relieve the hormone-driven tensions, but watching another girl, and her sister no less, in such a joyous exploration of her sexual needs, made her pussy started to heat up quickly. She couldn't move, couldn't turn her eyes away from the amazing sight.
Lisa was humping at her fingers, and furiously stroking her clit, she suddenly gasped out, "Oh yes, fuck me, fuck me HARD! Oh my God, I'M CUMMING!!" her voice rising to a shriek as her whole body convulsed in ecstasy as her orgasm tore through her, her body shuddering and twitching as the orgasm seized her and shook her in ecstasy. She drifted back down slowly, her body relaxing. She suddenly sensed Susan's presence and looked over at her.
She whipped the bedsheet over her, and snapped, "Don't you knock?"
Susan stammered, "I heard you groaning, and I thought you were, mmmm, in pain..."
Lisa was about to yell at Susan, but she saw the way her body was flushed, and her rock-hard nipples.
"Susie, did you like what you saw?" Lisa said gently.
Susan was dumbstruck, all she could do was nod, and Lisa said, "Have you ever masturbated with another girl, like Maddie?"
"No," Susan stammered, "I was too nervous to try and ask, having someone call me a pervert, and having it spread all over the place."
Lisa whispered, "Susie, would you like to enjoy a mutual masturbation session, with me?"
"Oh, please, yes!" Susan gasped, "I feel like I'm burning up!"
"Susie, drop the towel, come over here, and lie down next to me," Lisa's voice cooed softly at her.
Susan dropped the towel and noticed her sister's eyes glittering as she swept her eyes over her nudity. Susan also looked over Lisa's naked form, her sister was a knockout. Her pussy was clean-shaven, smooth, and bare, and Susan was fascinated by the sight. Susan's pussy had a wispy covering of hair as blonde as the hair on her head, and seeing her sister having shaved all of hers off, excited Susan, seeing her sister's feminine beauty so fully exposed. She lay down next to her sister. Susan's body was trembling slightly as Lisa kissed her lips gently.
"Just relax Susie," Lisa crooned in her ear, "I'll make you feel so good, baby."
Susan gave herself over to the pleasure of Lisa stroking her body, her fingers dancing over Susan, making the feelings churn harder, it felt like her pussy was steaming with heat. She trailed her fingers through Susan's wispy pubic hair, and they trailed lower, her fingers stroking over the outside of Susan's pussy, gently tracing the folds of her pussy lips, and Susan moaned at the flame of pleasure that leaped up, as Lisa's fingers slid slowly, teasingly over her.
"Does that feel good, baby?" Lisa whispered.
"Lissie, Oh my goodness, YES!" Susan gasped.
Lisa grinned, and her fingers slipped inside Susan's pussy, her fingers getting slippery from all the cream that Susan had been churning up. Susan groaned with pleasure as she felt her sister's fingers slip inside her.
