More of a question

Marsha lays down beside Kira, places her leg over her and begins to kiss Kira softly and passionately. Marsha rolled on top of Kira, their sexy bodies pressed against each other, rubbing and feeling every inch of the other possible. Marsha then moved to kiss and suck on Kira's ear and when there she whispered, "I want you to be my Andrew's personal fuck toy. If he gets off I want you to be the one he is fucking."

This startled Kira, that and the fact that Andrew and returned his now re-hardened cock to her pussy, getting it nice and wet. Marsha then smiled and said, "I know you have feelings for him, I know you want to be his, and I will let you be his so long as he is here. And if you do a good enough job pleasing him," Kira's mouth expanded in an O as Andrew did something she forgot she teased him about, Andrew was positioning his cock at her ass and was gently pushing into her tight and now wet rose bud. "Then you might join us out of here, so you can feel that cock in your pussy and ass all that you want."

As he finished sheathing his cock in her ass he allowed her to adjust to his size, and once she was he began sliding in and out of her ass, Kira finally got her wits together enough so that she could answer Marsha, or at least she was in so much pleasure that she was just responding to it "Oh God yes, yes, I will fuck this cock all day if I could."

Marsha smiled and then turned and startled Kira's chest, but not so much that Kira could reach Marsha's clit and pussy, so it was more of a tease for her, while Marsha leaned down and started sucking on Kira's clit, which also gave her a front row seat to Andrew fucking Kira's ass, which caused Marsha to get extremely wet, but she knew that it was best if she didn't let Kira play, this was her initiation. After a minute or so Marsha stuck two fingers into Kira's pussy and started to finger her.

"OH OH OH FUUUUUUUUUCKKKK," Kira moaned as Marsha found her g-spot and stimulated it along with sucking on Kira's clit while Andrew fucked her ass. All of this caused Kira to cum as hard as ever, and she did her best to grind against everything inside her, which caused her to orgasm harder and harder.

After she came down from her orgasm she lay back and just enjoyed the feelings of electricity going through her body. After a minute both Andrew and Marsha were laying beside her, one on each side, each playing with a different part of Kira.

"Wow, that was fun," Kira said laughing, which caused both her lovers to laugh and smile. "But I will do my best to be Andrew's fuck toy, but I can't guarantee it, as I do have a job here and there are tons of others for him to fuck. But I promise I will always share his bed at night, if that helps any."

Kira looked between the two of them as they all smiled. "That is fine with me Kira, but for the rest of the night, lets rest. We have an early riser here with us." Marsha said smiling as she noticed Andrew dozing.

"But Marsha you said that the pill we gave Andrew really worked? The only meds that we gave him were an antibiotic and anti-fungal. He is part of the control, what we are measuring against to see how well the meds are working." Kira told her as she cuddled up to Marsha's sexy body, running her own hand down Marsha's side, sending cold chills along her body, and to her pussy that still hasn't gotten off since she rode Kira's face.

"Oh I was told it was an experiment for some ****, so I just thought," Marsha was cut off by Kira's lips on hers.

"Don't worry, he is fine, very fine." Kira smiled. "But I just want to thank you for allowing me to share him with you," with that Kira slid down Marsha's body and placed her mouth between Marsha's legs as she gave her a nice long lick.
