By the time I got back, the two of them were already rubbing all over each other. Amy had reached over and placed a hand on Dawn's naked breast and was squeezing her nipple. Dawn looked as if she were in heaven. Dawn slid her hand up from Amy's crotch and grabbed one of Amy's large breasts and began to gently massage and squeeze it in her hand. They slowly turned to face each other on the sofa as they looked into each other's eyes. Dawn moved her other hand up to Amy's other breast and began to slowly explore through the fabric of the bikini top. I could see Dawn's breath beginning to change. She looked at me out of the corner of her eye, I just winked at her and she looked back into Amy's eyes. Amy slowly moved her other hand up and was now holding each of Dawn's naked breasts ever so gently.
This continued for several minutes then Dawn reached over and untied the two laces on Amy's top. Amy removed one hand from Dawn's breast and reached up and pulled the top off.
"Thanks," Amy said softly.
Dawn was looking down at Amy's breasts then moved her hands so she could roll Amy's huge erect nipples between her fingers. Amy tilted her head back and moaned softly, when she did Dawn leaned forward and kissed Amy's throat softly. I could see that Dawn was not going to be shy about this. Amy tilted her head back down and at the same time moved one hand behind Dawn's neck. In one motion she pulled Dawn's head quickly toward hers and then placed a big kiss on Dawn's lips. I heard one of them moan and Dawn began to reciprocate and they were quickly kissing hard and exploring each other's mouth with their tongues.
I didn't know if I was going to be able to sit there and not have my cock explode. They kissed passionately for several minutes and then Amy slowly pushed back on Dawn. As she fell away from her and back onto the sofa, Amy leaned forward and slowly moved her head down and began to suck one of Dawn's nipples.
Dawn's head went back and she reached up with both hands and pulled Amy's head into her breasts. Amy was sucking hard on Dawn's nipple, she then began to tongue it in small circles. Amy began to lightly bite down on Dawn's nipple and pull at it. I knew this would drive Dawn wild, she always got hotter when I did it.
Dawn's hands began to pull at Amy's red hair as she became more aggressive in biting on her nipple. Amy quickly switched to her other nipple and bit down. Dawn threw her head back again and appeared to be in ecstasy. The sight of another woman sucking my wife's nipples was really driving me crazy. I grabbed the remote and punched up the cameras in the study and looked at the TV screen to make sure they were getting all of this.
I had to refrain from grabbing my hard as steel cock and stroking it, I knew if I touched it at this point I would explode in a huge orgasm.
Dawn's head was leaning all the way back, her mouth open, breathing very hard. I wondered if she was going to have an orgasm just from Amy sucking and biting on her nipples. Amy raised her head and moved up and kissed Dawn passionately on the lips again, then she began kissing Dawn on the neck and slowly moved down to between her breasts. She slowly gave each nipple a lick and a kiss and then began kissing and slowly working her way down toward Dawn's stomach. Inch by inch Amy slowly moved lower and lower kissing as she went. Dawn was now looking up watching her while still grabbing handfuls of red hair.
