Of course I follow. It's *my* room!

Once I'd gathered my posture and managed to stand up both sisters were already in the room.
The break was most welcome to allow my hard on to ease up a bit, something desperately needed to endure the expected upcoming ordeal.

As I closed the door behind me I couldn't see Tara, but the sight of Sara was more than sufficient. She stood by the desk at the other end of the room, facing it, with her head turned towards me. This was the first time I could get a really good look at her.
As she stood there I began eating her with my eyes, from bottom to top. On her feet she wore black high heel sandals that not only were sexy by themselves, but also exposed the reinforcements of her full fledged stockings. These in turn were expertly fitted without a wrinkle, and each had a barely visible seam running up the back of her shapely legs, ending at the stocking tops. That part also very sexy. Her stockings were held up by suspender straps, as required for this type of stockings. She used a black tube top as skirt, at the moment hoisted up a bit with the lower end half way down her buttocks and the top around her waist. Between the buttocks her orange panties were screaming for attention, the part above where they split into two strings that is. Above her makeshift skirt she wore a thin white blouse through which the outlines of an orange bra was clearly visible. Half turned as she was I had the profile of her nearest titty in clear view. I could swear I saw her nipple poking out. Her eyes met mine.

• ”What took you so long?” she asked. ”Seems like you enjoyed the view, ...” she added, taking a quick look at my prick, now completely 'recovered' from its short pause, ”... which is a good thing. I want you to fuck me from behind, right now!”
  With that she turned her back at me and bent forward over the desk, resting her lower arms and elbows on it. ”Come here and stick your stiff meat inside my acing pussy! Fuck me hard!”
  In her new position I could clearly see the target for my cock. To aid and urge me further she reached back with her hands and spread her lips for me, opening up wide.
  There was no way I could stay away from this pussy, even if I'd wanted to. Now I took three steps to get up behind her, and then used my hand to guide my cock to the entrance of Sara's wet cunt. I let it rest there as I used both hands to grab her hips before pulling myself all the way inside her in one go.

• ”OOoohhh!!” Sara moaned, ”That's the way to do it!”
  I began pumping her in long hard strokes. She just stood there, rocking back and forth with every thrust, enjoying the sensation. It seemed like her only physical effort was to tighten the muscles surrounding her sweet pussy, and she did that like a real sex-athlete.

  On the wall above the desk was a mirror. In it I could see Sara's pretty face and a bit of cleavage.
  I leaned forward and reached under her chest, grabbing a breast in each hand. They felt firm and I could clearly feel the erect nipples through her blouse and bra.
  Holding on to her tits I pulled her upwards 'til she stood with her arms straight. Then I fondled her boobs for a short while, enjoying the mirror view, before pulling the front of her blouse apart.
  What a sight! She didn't wear a regular bra, but one matching her panties. It was orange, and instead of full cups it had spandex ribbons, an inch and a half wide, forming like a tube around the base of each breast, shaping and holding it in place while leaving most of it exposed. No wonder I could feel her nipples...
  I renewed my efforts rubbing these lovely tits while continuing the inside massage of her tight cunt.
  That caused Sara to go wild.

• ”Yes! Yes! Yes!” She yelled. ”Keep it going, you hot stud!”

  Now I noticed Tara again. She laid on the bed watching the show, obviously getting aroused by it. Her knees were spread wide and I could see her wonderful pussy, or rather; I would have, hadn't she been rubbing it with her hands. I kept watching Tara while fucking her twin sister. As I was looking I noticed Tara had removed her pantyhose. That became evident as she slowly pulled them, or at least a similar pair, out of her cunt where she obviously had inserted it while I was busy admiring Sara. Tara pulled the hoisery over her clit and up towards her belly, all the while staring hungrily into my eyes through the mirror.
  It was only my earlier orgasm that helped me hold back during all this.

  Once Tara's pantyhose was all out, she stood up and walked up behind me. Suddenly she pulled her pantyhose over my head. It was all wet with her juice, and it was very arousing inhaling all those pheromones through my mouth and nose.
  Before I noticed what was going on Tara removed it again. She now stood on the desk in front of me, straddling her sister.

• ”Eat me!” Tara ordered. Her pulsating pussy only a few inches from my face emphasised the words.
• ”Yes miss”, I said, and dived right in at it. Licking and sucking this delicious womanhood was a real feast.
• ”Don't spoil him, sis”, Sara said, ”I want to come before he does!”
• ”All right”, Tara replied, ”as long I as get my part.”
• ”You know you'll get it, as always.”
  Tara pulled away from me, backing off a bit before jumping off the table.
• ”Please help me get off.” Sara requested.

• ”Will do!” Tara said, and dived in under the desk.
  She sat down on the floor between Sara's legs, facing me, and began licking Sara's clit while I fucked the cunt next to it.
  This sent Sara into a gear I thought didn't exist. She was squirming, moaning and doing all sorts of noises. With a bit of luck she'd cum within the next few seconds, before I'd have to let loose my own orgasm.

  Sara did get her orgasm, and boy , what an orgasm! It was a real earth shaker.
  But I didn't want to get off just yet. Thanks to my previous cumming I was able to hold back and plan my next move.
