Jenna lowered her head and spat in her hands then wrapped her fingers delicately around my cock and frigged me. The feeling was indescribable, so exciting that I soon started to moan and, as I expected, I did not last long. It seemed that in no time at all I felt my orgasm well up and my dick erupted in long, milky ropes as I came so hard I could not remember having ever felt such intensity before. My moans increased and became grunts during my orgasm and I am certain I did not last more than a minute. My sister had tried to contain my cum with her hands but some of my stuff ended up on her neck and shoulders.
Jenna kept her hands wrapped around my cock for a moment as she glanced at me, smiling weakly.
“That didn’t go too badly, did it? I hope you feel better.”
I smiled back at her. I felt I should apologize to her but I did not exactly manage to say the words.
“My balls were hurting, what you did was perfect, exactly what I needed.”
I was about to pull away and get dressed but Jenna surprised me. Keeping her cum-soaked hands on my cock, she began masturbating me again.
“I know you’re not done, Brad.”
My shaft had barely wilted after I came as Jenna had not let go of it. Now, with her left hand wrapped around its base, she caressed the end of my dick a few times with her right fingertips. I could feel my rod growing quickly and it was not long before it had reached its full rigidity. Jenna released me at this point, got up and made me sit on the side of the bed. She pushed my shoulders until I fell backward on her mattress. Giddy with lust, I grabbed one of her pillows and placed it beneath my head for a better look at what my sister would do. She knelt between my legs and reaching for my cock with her left hand, she wrapped it around the middle and moved her hand down slowly to keep my foreskin fully down. As she held the base of my shaft securely with her left hand, Jenna looked at me and, smiling shyly, she began getting me off again. I suppose her hands were still slick with my semen as the friction was highly pleasing and I abandoned myself to the heady sensation with my head moving side to side and my eyes closing despite my desire to watch as Jenna did me, spitting in her hands as she worked me. I lasted longer this time but not very much so because the feel of Jenna’s fingers stroking the head of my cock was almost too much to endure. The right thumb and first finger of her right hand had formed a tight circle around the ridge beneath the head and I could not help moaning as she moved her hand up and down with short but fairly rapid movements. My sister was moving her hand barely a half inch or so back and forth along my cock but, as the pleasure was concentrated so directly on the head and the ridge underneath, my neck arched backward on the pillow and my breath hissed sharply between my lips with the intensity of the feeling. I could feel my thighs shaking as my pelvis pushed toward the source of the sensation and I knew the feeling could not continue, the pleasure was too acute and, indeed, after a couple of minutes, my feet were pushing my pelvis upward as I came off again. My jizz shot out in more long, milky strings and Jenna just let it fly, continuing her ministrations gently until I had nothing left.
