That was the moment. The push over the threshold. All my senses felt numb and yet so sensitive at the same time. My cock was fizzing and on fire as Rosie's hands manipulated it but my legs felt leaden and detached. My eyes and ears felt exhilarated by the sights and sounds of Steve 'working' Rosie's tits and pussy but my head felt woozy and befuddled. My body scorched hot, roasting hot yet parts of me were shivering.
I decided we needed to lose some clothes as Steve was performing admirably but was somewhat hampered by the onesie. Whilst it was unzipped right down to Rosie's crotch, I could tell he wanted further access.
Rosie was more or less leaning back against my chest, lost in the ecstasy of the moment and whilst still supporting her weight I scooped the onesie off her shoulders and down her back. As a threesome we all swayed and stumbled as she stepped out of the legs of the onesie. I don't think Steve's mouth left her breasts once during this moment.
A brief hiatus in the proceedings occurred when Rosie let go of my cock so i could remove my t-shirt and jeans, kicking them idly in the corner. Rosie had wrestled Steve's mouth from her breasts and guided him into the sitting position on the sofa. The tent in his jeans displayed loud and proud for Rosie's indulgence.
Kneeling on the floor and stark naked between Steve's thighs, she began to hastily undo his jeans. Clawing at the belt buckle and yanking at the buttons until she had revealed his hard cock. In one swift movement she grasped his hard shaft in her left hand and plunged two thirds of it into her mouth. Steve's hips bucked as the sudden envelopment of his cock sent shockwaves of pleasure throughout his body. Rosie kept Steve in her mouth and with her free hand wrenched his jeans down his thighs and then off his feet. Now with both hands positioned on his bare thighs she started to bob her head. This was no clumsy, naive suck blowjob. This was a sensual, passionate use of her mouth and tongue to stimulate Steve's engorged, twitching cock. Her mouth was partially open and her lips never closed fully against his cock and she lavished her tongue against the sensitive underside of his cockhead and guided him slowly in and out. Her saliva and undoubtedly Steve's pre-cum glided down the shimmering shaft of his cock to pool and flow around his groin. It truly was a sight to behold.
My attention was drawn to Rosie's womanly arse poised in the air a few feet in front of me. I cupped my palm and placed it against her wetness and rubbed up and down. With the gentlest of pressure my middle finger was welcomed into her soaking slit and beyond. Removing my hand i massaged her wetness onto my cock and positioned myself to enter her. With a slow deliberate thrust forward I entered her and adjusted my knees around her legs to gain a better stance to fuck her. Rosie's pussy sucked luxuriously at my cock as I slowly drew in and out of her. I want to keep my motions as gentle as I possibly could because Rosie was using her mouth so sensuously that I felt a hard firm fucking action would ruin the moment. Thus I proceeded to slide gracefully as far into her as I could, give a slight firm press forward against her arse to punctuate the moment and then withdraw out again. I repeated this motion a great number of times and caressed her arse and back with light strokes of my hands. I could feel Rosie's wetness spreading down her thighs and transferring to my legs also.
Steve started to make urgent noises, indicating that he probably wasn't going to last much longer. Rosie had other ideas, ceased the oral stimulus and with a delicate arse wriggle extricated my cock from her pussy too. With a mischievous glint in her eyes she shimmied herself into a sitting position next to Steve and directed his next move by spreading her legs and saying simply "My turn!"
