Billy's powerful body responded. Nita lost her own control. She leaned down to gently nip Mary's lips, then rammed her tongue down the woman's throat.
Billy groaned. Mary's body stiffened and arched as a blazing orgasm tore through her. Nita's hands traveled rapidly over Mary's body, feeling of her tits, her belly, and down to where Billy's prick punched into her hot body. Mary's orgasm had barely subsided before Nita was pushing at them, moving them into a new position.
"Lie back, Mary. Billy, get behind me and fuck me. Shove your hard cock all the way up my throat from the bottom!"
Nita got on all fours in front of Mary, her head over the woman's crotch. Billy quickly mounted the young girl. She held her breath as his sleek, muscled body hovered over her back. His fingers guided his shaft carefully down to the mouth of her cunt.
Nita groaned softly when Billy's prick eased into her wet, hot cunt. Her head dipped down. Her mouth closed over Mary's soppy cunt. Mary held the girl's head tenderly with both hands and lifted her cunt to position it better for Nita to eat. Nita's mouth settled over Mary's twat as she nestled closer, her hands pushing Mary's thighs farther apart.
Mary gasped as the young brunette flicked her tongue out and the first piercing bliss quickly became a series of blazing, wet stabs of joy. Mary was still on a high plateau of erotic sensation from her previous orgasms, so it wasn't going to take much to get her off again.
Mary wrapped her legs around Nita's head, shivering and moaning as the delicious thrills raced through her eager cunt. Nita was quickly becoming an artist at sucking pussy.
All the while, Nita jerked and shuddered as Billy's throbbing dick thrust deeply into her burning hole. She swung her buttocks to and fro in a frantic rhythm, excited as much by Mary's sweet flesh as by Billy's pulsating hardness, squirming her damp flesh against his thick pubic hair while his hands slid up her stomach to cup her swinging tits.
Nita reached up to fondle Mary's satiny tits, loving their swollen nipples with her fingertips. Filling her nostrils with Mary's licentious scent, Nita plunged into the succulent meat, quickly finding the woman's clit. The older woman squirmed and moaned beneath the fierce kisses, chanting Nita's name like a prayer, twining her fingers in Nita's hair as the hot, stinging thrills rippled through her soppy slit. In addition to her searing lips and tongue, Nita stroked and rubbed every inch of Mary's silken flesh she could reach, from her swollen tits down to her bouncing buttocks. Nita immersed herself in the blonde's luscious box, seeking the strange, delicious fulfillment she craved at that moment.
The moment she sensed Billy's impending climax, Nita vibrated her tongue furiously in Mary's luscious snatch. The blonde issued a soft scream of ecstasy, quivering her heated body wildly. Nita felt the spasm of joy in Mary's sudden convulsive movement. At the same moment, Billy's thunderous explosion tore into the soft walls of Nita's cunt.
Nita arched her body and clamped onto his shaft with all her might, sucking furiously on Mary's cunt to vent her passion as her own orgasm threatened to rip her apart.
When Billy had spent his load, he fell to the side and stretched out flat on his back. Nita sagged forward, her cheek resting in Mary's thick pubic hair.
"That was good!" Nita grunted.
"That was fantastic!" Mary said.
"Billy, did you like Mary's pussy? Did you like fucking her?"
Billy patted Nita on the top of her head gently. "She's great, baby. Thank you for inviting me."
"You'd better wait until the night's over before you thank me," Nita replied in a teasing voice. "You might not be so happy later on. There are two pussies and only one cock here, remember."
"I have a tongue," Billy replied confidently. "I can always suck on a pussy."
"And you do it very well, too," Mary said, smiling as she recalled how well he had sucked her pussy earlier.
"Speaking of sucking," Nita said, "Mary, I want you to teach me how to suck a cock. There have been several times lately when I wanted to suck Billy's but I don't know how."
"It's my cock," Billy said, hurt that he wasn't being consulted. "Why don't you ask me to teach you?"
"Because I want Mary to show me how she does it. If you aren't satisfied with that, you can add your two cents worth later. Will you show me, Mary?"
"I'd be happy to, darling. I can't believe you've gotten this far along in life and never had a cock in your mouth."
"Well, I haven't. But having one in your mouth and knowing how to really suck one are not the same thing."
"You can say that again!" Billy chimed in. "Some girls don't know beans about sucking a cock."
"And that's why I want to be taught by an expert," Nita replied.
"There it is, dear," Mary said, pointing to Billy's prick. "Let's see how good your natural instincts are."
Nita got on her knees by the prostrate Billy. She lifted his prick in one hand and began kissing it, brushing her lips over it lightly. As she warmed to her task, and as her arousal began asserting itself more fully, she took the head of the soft dick into her mouth. Feeling the bulging tip of his prick against the roof of her mouth set off a chain reaction of lustful endeavor. In seconds, she was devouring him with a zeal which even Billy found surprising."
She could take all of his prong into her mouth while it was still soft, so she sucked up the full length. Mary watched carefully until the prick began getting hard.
"That's very good," Mary said, nodding her approval. "That's the way to suck it up to an erection. How about it, Billy? Do you think she knows enough about sucking a cock? Should I give her some pointers?"
"For a beginner, she's not half bad," Billy said, his breathing getting shallow and rapid. "I'm sure you could help her a little, though. She does seem a little timid in her approach."
Mary gently pulled Nita's face up from Billy's loins. She gave the young woman a short, but amazingly thorough, course in the sensitive parts of the male organ, pointing out all the places where she could use her tongue most effectively in stirring a man with the greatest efficiency. Nita, who had supposed that the tool was equally sensitive in all areas, listened carefully and digested all the information with interest.
"And another thing," Mary added, "you don't have to worry about hurting a cock. Not unless you bite him, of course, and even then you could do some good if you don't go wild. Gentle nips are fun. Here, try holding the head of his cock between the roof of your mouth and the top of your tongue. Yes, take it, that's right, there, now press as hard as you can with your tongue-try to flatten the head out like a pancake. That's it! He'll tell you if you hurt him."
"Ahhhhh, damn!" Billy hissed. "There's no hurt!" He trembled ecstatically. "Damn, she's good! She's already so good!"
"There, you see?" Mary said, patting the back of Nita's head tenderly. "You're getting the hang of it. Cocksucking really isn't hard, is it?" She put one hand on one of Nita's cheeks. "Now, keep that grip on him with your mouth and rotate your head around a little. Back and forth. That's the way. See how much friction you can generate on his cock? Oh, yes! My, you're a good student! Are you going to suck him off? Are you going to let him come in your mouth?"
Nita lifted her mouth from Billy's stiff prick. "Yes! I'm going to get his load! I want to taste it! Want to swallow it!"
"Well, dear, there it is! Yummy for the tummy!" Mary wrapped her fist around Billy's cock shaft and shook the instrument gently, chuckling at Nita's eagerness.
Nita held his prick steady with one hand and lowered her mouth again, once more taking the head between her lips beginning to suck it. She drew it slowly into the wet, glorious sexiness of her face. She tightened her lips behind the head and began working her head up and down, her hand moving steadily up and down the length of his shaft.
