Reinforcements

Kelly really seems to be struggling to keep riding her boyfriend. If they have been going at it since you had left earlier, you can't blame her. You wonder why Tom can't finish despite such a hot girlfriend with a tight pussy. You're starting to lose interest when Tia suddenly pushes the door open wider to enter the room and she goes it. You sneak it quickly before she closes the door behind her silently. Then, she slips her robe off her shoulders and swiftly removes her lingerie, getting naked. Her breasts are huge and defy gravity and she looks amazing.

Tia then tip toes to the bed, taps Kelly on the shoulder and quickly puts a hand over the petite Asian's mouth to prevent her from uttering anything in surprise. Tia motions for Kelly to stay quiet before she releases her hand.

"Don't stop..." Tom says from under Kelly and she moves her hips awkwardly, now very self aware with Tia in the room. Tia cups her hands over Kelly's ear and whispers something to her and Kelly nods after a while. You wonder Tia said. The next thing you know, Tia climbs gingerly onto the bed, steps over Tom and lowers her crotch onto his face.

"Wha?!?" you hear Tom's muffled utterance as Tia sits on his face and he must have opened his eyes by now.

Tia laughs and raises herself up enough to let Tom breathe and speak. "It's okay Tom, Kelly says she's fine with it and it sounded like she could use some reinforcements.

"Um... what about Mark?" Tom says, staring up at his roommate's girlfriend's pussy.

"Mark's sound asleep. He always dead as a log after sex. Don't worry, he used a condom. You won't taste him in my pussy," Tia says, starting to lower herself back down, but Tom stops her with 1 hand on her left inner thigh.

"Kelly, you sure about this?" he asks.

"Yeah, I'm totally cool with it. I know you've always wanted to have a threesome, right? Plus I've seen you eyeing Tia every time she comes over. I can't blame you, she's hot!" Kelly says, sitting on Tom's cock and getting to rest.

"Aw! Thank you! You're so sexy too!" Tia says, looking over her shoulder. With Kelly's permission, Tom lets go of his hand and Tia sits on his face again. This time, he's a knowing participant and he starts to lick her pussy. "Oh yeah..." Tia moans, "Lick my pussy... You're good at this, Tom... Honestly, I've always thought you were cute and sometimes I fantasize about you when I'm with Mark, thinking of you 2 in here.... Sometimes I close my eyes and pretend Kelly and I swapping places..." she goes on and Kelly blushes deeply.

"Speaking of swapping places..." Kelly says, she climbs off Tom's cock and motions for Tia to take her place. However, in the process of dismounting Tom, the condom on him unfurls and slips off onto the bed. "Shit! That was our last one!" Kelly says in dismay. You try not to laugh out loud since she had let you fuck her bareback earlier. You guess her boyfriend doesn't have the luxury. "Do you have some back in Mark's room?" Kelly asks Tia.

"Yeah..." Tia says, eyeing Tom's cock. She lifts herself away from his face, turns around, and moves towards his waist. "... I don't want to go back and get 1 though... feels weird to do that... do you mind, Tom?" Tia says, already starting to lower herself onto his cock. She pauses when the tip presses against her pussy lips.

"No... I'll pull out," Tom says eagerly, not wanting to miss out on fucking Tia without a condom.

"Kelly? You okay with this?" Tia says Kelly for confirmation.

Kelly gulps and nods and the moment she does, Tia sinks onto her boyfriend's cock in the reverse cowgirl position.

"Fuck! This feels nice!" Tia moans loudly, reaching back to place her hands on Tom's chest for support while he holds her hips and she starts riding him. Kelly gets closer to them and she reaches over to massage Tia's clit while she fucks Tom, even helping to put his cock back into her pussy whenever it slips out.

Soon, Tia really gets into it and she's vocal about her pleasure as she rides Tom harder and faster, arguably doing a better job than Kelly was doing when you and Tia first came into the room. It doesn't take much longer before Tom is grunting and exhaling loudly too and building up to his climax.

"I'm about to.... Tia, I'm so close!" Tom moans, pushing up on Tia on her hips to try to get her off him.

"Oh yeah! Me too! Your cock feels so good!" Tia moans, throwing her head back and gyrating her hips as wildly as she can in the heat of the moment. Tom is bigger and stronger and he could probably push her off if he really wanted to, but instead they stay joined together. Kelly stops playing with Tia's clit but remains sitting next to them and watching closely as Tia moans "Yes, yes, yes!" and trembles as she sits on Tom's cock and cums first. About a second later, Tom groans "UGHHH!" and is definitely cumming too. About the same time, Tom and Tia let out a sigh of contentment as they experience their orgasms together and you can't tell from her expression what Kelly is thinking.

After a while, Tia raises herself off Tom's cock and it's covered with her juices and his cum. To your surprise, Kelly bends over and proceeds to suck on it until Tia goes to join her and they take turns until Tom's cock is just covered in their saliva.
