Spa Story Pt. 06

In the early hours I awoke to the light filtering through the curtains, Steve was still fast asleep. I carefully slipped out of the bed and went to the shared bathroom. After peeing I needed a drink, so set off to the kitchen, as I passed Hekla's room, I heard Icelandic voices inside, the door was open, so thinking I would ask if they wanted anything from the kitchen, I took a quick look inside. I could see Hekla sitting cross legged on the bed, I could not see Freja without going closer to the door, but they were obviously deep in conversation. I was about to knock on the door when Hekla slid her hand under her t-shirt and began to caress her breast. My sex twitched at this sight, what were the sisters up to? I decided to watch and see what happened next.

It was clear from the tone of her voice that Freja was instructing her big sister. Hekla pulled her shirt up over her head exposing her beautiful small breasts then resumed massaging them with one hand. She now uncrossed her legs and spread them, leaning back slightly on the headboard, slipped her other hand inside her white cotton panties, and began to touch herself. I needed to see more but feared they would see me and stop. I carefully moved closer to the opening, but the door still obscured my view, so I moved closer. Almost in the room now, I finally could see Freja. She was reclining in a chair facing her sister, she too was only wearing white panties, and was mirroring her sister's actions, caressing her flat chest with one hand whilst delving into her panties with the other. From this angle I could see her finger moving within her panties, pressing against the fabric as she pleasured herself. Luckily for me, their attention was on each other as they could easily have seen me.

My fingers slipped between my legs, and I started to rub myself through the thin fabric of my underwear. Freja had stopped talking and both sisters were beginning to moan quietly, as they watched each other intently. I lifted my own t-shirt and slipped my fingers down inside my pants, I quickly found my slick nub, my touch sent shockwaves through my abdomen. Freja needing easier access, lifted herself slightly and slid her panties down her thighs and over her knees, letting them drop to the floor before letting her knees fall to the side, thus exposing her beautiful pussy to my view. She ran her fingers over her scant pubes then between her hairless lips. Hekla and I watching her intently, rubbed fiercely at our own pussies. Briefly pausing my self-pleasure, I pushed my own pants over my hips and let them drop to the floor, before resuming masturbation. Freja, through moans managed to instruct her sister to remove her own panties, at Freja's command, Hekla raised her arse off the bed and pulled down her panties, before seductively spreading her legs wide for her sister.

Both girls now completely naked, slowly massaged their swollen clits' their eyes locked intently upon each other's actions. It was a contest of wills, they knew what they were doing was wrong, but they had not stepped over the final line after which they knew they would be utterly lost. The intensity of their passion drove me wild with lust and anticipation of the dam bursting. The movements of Hekla's fingers were becoming erratic, her chest was heaving with the weight of desire she was controlling, she could not last long. I was using both hands now, my fingers delving into my pussy as I rubbed furiously on my nub. I had to lean against the door jamb to stop from collapsing.

Freja's eyes were like ice, locked on her sister, she was controlling her passion with an iron grip. Hekla on the other hand was gasping, her breath was coming in short gasps, she had to succumb to break the final taboo, all the events of the previous day had loosened her moral boundaries, this was just one more step, but still, they both withheld, neither willing to commit that sin. I moaned with desire, "just do it! "They must have heard me, but if they did, neither of them acknowledged my presence. If they did not fuck soon, I would have to go in and force them. Freja held her icy gaze, Hekla had gained some more control. Perhaps deliberately to break her younger sibling's will, she sucked a finger, then twisting her hips slightly pressed the lubricated digit against her pink arsehole, pushing it inside herself. With this act I lost control, the warm sensation in my stomach became a fierce fire and I shuddered as a wave of orgasmic pleasure spread through my body. Hekla's extra years and sexual experience had outflanked her little sister. Freja despite her rigid control and dominant sexual personality broke first. Hekla the coy seductive temptress had won, it would be Freja who broke the taboo.

Almost leaping from her seat Freja walked over to the bed, dropped between her sister's legs, and applied her mouth to Hekla's smooth-shaven mound. Freja attacked her sister's sex with all her repressed passion. Her mouth sucking, her tongue darting and probing. She slid her fingers under her sister and began probing her pussy and anus, one, then two and three fingers pressed into her tight hole. All the control had gone, Freja pleasured her sister with abandon. It was Hekla who was now in control, despite the pleasure she was receiving she was able to lift Freja's head and motioned for her to roll on her back. Freja complied allowing Hekla to carefully align herself above her in a sixty-nine position. They at once began licking each other in unison, their forbidden congress was complete. Freja rimmed Hekla's puckered anus, then licked from her sister's dripping pussy to her swollen bud. Hekla in turn sucked and licked Freja's clit. Their fingers probed and rubbed each other's pussies' and anus's as they orally fucked.

My own orgasm subsided, as theirs approached, both girls' actions became increasingly frantic until Hekla suddenly lost the ability to support herself and collapsed onto her sister, her thighs sprawling on either side of her sister's head, her mouth coming away from Freja's pussy as she felt the bliss of release. With that I slipped out of the door and headed back to our room, leaving the sisters alone to complete their lovemaking. Steve was still asleep as I climbed in beside him.
