Erotica Sex Story: Chapter 8: Unsafe Orgy - Samantha returns from a mysterious trip with newly enhanced boobs. Aaron is impressed, but things really get interesting when Mandy stuffs her daughter's bra and loves the way she looks and the reaction she gets. If Aaron can't keep his hands off Samantha's chest or keep from jacking off in front of everyone because of her new boobs, what's going to happen when Mandy decides to go even larger than her daughter, much larger?

“Help me up James; my legs are like rubber.” Samantha was already standing and licking one of her own sensitive nipples. James was distracted by that, so Aaron went to Mandy’s side and offered her his arm. As he helped her to her feet, she noticed Aaron wasn’t wearing any pants and had an extremely hard erection throbbing in her face. “Looks like you enjoyed the show Samantha and I put on. I didn’t even notice you whip that thing out! Damn, help hold me up Aaron.”

Aaron put his arm around the horny mother to support her, and his free hand went for one of her big tits. Two squeezes, and he was lowering his head to suck one of Mandy’s rock hard nipples into his mouth as he started humping her leg. Mandy giggled, and started panting as her overly sensitive nipples made her want to join in with What Aaron was doing. She put one hand behind Aaron’s head to encourage his suckling, not that he needed any encouragement to lavish attention on her huge tits. She was also rocking her hip against his hard cock.

James was not amused, “That’s way out of line you two. Both of us feeling Mandy up posing for pictures is one thing, but you can’t suck on my wife’s tits or hump her leg like a dog.” James spun Mandy away from Aaron, and still on shaky legs she leaned on her husband for support.

Grabbing James’ cock, which was just as hard as Aaron’s, she told him, “Easy, things may have gotten a bit out of hand with the titty show Samantha and I had. You couldn’t keep your pants on any more than Aaron could. If you had been paying attention to your wife instead of watching my daughter lick her nipples, you could have been the one humping my leg and putting a giant tit in your face. You still can you know.” Mandy gently stroked her husband’s cock the entire time she was talking, and James couldn’t stay mad. Instead of sucking on her tits like Aaron had though, he kissed his wife on the mouth, and his hard cock was poking her belly. “Oh hell, I’m not going to be able to keep my pants on either,” Mandy muttered between kisses.

While Mandy was wriggling out of the remainder of her clothing, Aaron went to Samantha with his mouth hanging open. He whispered to the teen, who was still licking her own nipples, “Having your mother’s giant jugs in my mouth has left me with the uncontrollable urge to suckle on a big pair of titties. Do you think I can take over?”

Smiling, Samantha presented her ample rack to Aaron, who eagerly went from tit to tit with his mouth. Licking and kissing the teen’s hard nipples made her unbelievably horny. Samantha’s tits might not have been as sensitive as her mothers, but she didn’t have the benefit of two orgasms to cool her down.

Not that the two climaxes Mandy experienced seemed to have slowed her down any. Aaron was too absorbed in what he was doing to Samantha’s jugs to notice, but Samantha heard her mother say, “Go get a condom James, my pussy is on fire even after cumming twice from having my super sensitive nipples played with. Aaron would have probably made me cum a third time if you hadn’t stopped him. Fucking hurry! I need you inside me like two minutes ago.”

Samantha got even more excited when she heard her step father reply. “My cock is insanely sensitive too. I promise I won’t cum in you, but just let me thrust into you a few times. That’s it. Get back in the floor and I’ll get on top of you like Samantha was.”

Mandy did what James told her too and used her hand to guide his cock to the entrance of her pussy. “I don’t think that’s a good idea honey. You had better go get that condom.” She didn’t release her grip on her husband’s cock and was actually sliding it up and down her needy slit.

“You have to let go if you want me to go get that condom.”

“But I don’t want to let go,” Mandy whined playfully. Samantha was now in the process of getting completely naked like her mother.

“I guess I’m coming in then,” James teased back as he thrust at his wife.

“Coming in is one thing, but cumming in me is another,” Mandy giggled.

James didn’t stop though, and was easily able to start guiding his cock into her body.

“James, this isn’t safe! You know I’m not on any sort of birth control. It feels so good though. Like, exactly what I fucking needed good.”

“Shhh, shhh, I promise I won’t cum in you. Just a little bit of harmless thrusting and then I’ll pull out and go get that rubber before we finish.”

“Yeah, you promise? Well, if you promise, I guess it’s OK.” Mandy said while rocking her hips eagerly against her husband’s intruding member.

Samantha scooted back to sat on the edge of the desk in the room, now completely naked. Aaron followed her sucking on her nipples all the while. “Aaron, I’ve never seen your cock so hard, not even when I was deep throating it!” Samantha whispered to him.

“How can I not be insanely hard when you and your mom are topless and I’ve gotten to play with both of your enormous sets of tits?”

“Well, I’m insanely horny too, more so than any of the times you fucked me.” As she said this she took his cock in her hand and stroked him drawing it closer to her pussy.

“You need me to go upstairs and get some condoms? It looks like your Mom and James need one also.”

“I don’t want to wait; go ahead and start fucking me!” Samantha demanded. “Pappy can be the one to bring an extra condom down for us.”

Aaron protested, “Samantha, we can’t; it’s not safe.” He was using a hand to keep Samantha from guiding his cock inside her.

“Come on Aaron; fill your hands with my tits and stop resisting me. You know we both need this. But be quiet though; Mom will hear us if we carry on too much.”

He couldn’t resist the teen’s offer; he put his hands on Samantha’s huge knockers and started squeezing them. Between that and the girl stroking his cock, he grew harder than he thought possible. He exhaled, and allowed Samantha to guide his cock inside her warm, wet pussy. It was the first time feeling the sensation of fucking her without a condom on, and if he hadn’t been under the girl’s spell before, he was now! Samantha for her part held her breath to prevent herself from making the satisfied noise she usually made when feeling Aaron’s cock spreading her pussy lips.

However, their attempt at silence didn’t last beyond the first thrust Aaron made into Samantha’s unprotected pussy. He immediately started grunting with each thrust and Samantha panted in pleasure. The sounds made Aaron fuck even faster.

“Please tell me you got a condom before you put your dick in my girl,” Mandy demanded. When she didn’t get an answer, she turned her attention to James, “Honey, you’ve got to pull out! Samantha and Aaron are fucking and I don’t think they’re using a condom either. I’ve got to stop them before Aaron cums like a fire hose inside my daughter!”

Threatened with parental interruption, Samantha wrapped her legs around Aaron to make sure he couldn’t pull his cock from her pussy.”

“Samantha, quit that or I’ll ground you until your 18!” The girl slowly unwrapped her legs, and then Mandy tried to get James attention again. “James, are you listening to me? We all have to stop fucking before these after photos turn into a disaster!”
