Ingrid had trimmed my pubic hair, preparing my body to pose nude for her sketching class. Now she would be 'relieving' me so that I wouldn't get an erection in front of her students.
I arrived in her studio about an hour before the scheduled class. I found her sitting on her desk. Judging by her bare legs and feet, I figured she was naked under her shawl.
I undressed, walked over towards her. The shawl parted, and her clit was already peeking out of her shaved vulva, so I knew that she had already been touching herself. This thought excited me, I felt myself begin to stir. I told her that I would like to masturbate with her this time, without us touching each other, just for old times' sake. She laughed quietly, a touch of shyness, then confessed that she, too, wanted to masturbate right away.
With my hand I grasped my semi-erect shaft and slowly retracted my foreskin. My cock stiffened as I unsheathed my dark purple cockhead. My first stroke felt so overwhelming I thought I would cum in just a few strokes.
She looked up into my eyes. Told me she found it exciting to watch. She moved her knees further apart, began to slip her fingers between her lips. Alternating between rubbing her clit and shoving her fingers up inside herself. 'Oh, Robbie, cum for me!' she said, as I pumped away.
I was extremely aroused, my erection was very stiff and the head was throbbing, unusually swollen. I told her how aroused I was, and her reply was 'I find it all so very, very exciting to watch you pumping away, oh, so frantic this time, so desperate to cum!' I told her I couldn't afford to get a hardon in class.
Her breathing was just quick loud gasps. Now she was frantically rubbing just her clit. I cried out, 'Oh, I'm about to spend! I'm cumming! Oh!' Suddenly I moved closer to her, grasping her open thighs, my legs touching the inside of her open thighs, and my untouched cock bobbed about as it squirted cum. With her free hand she grabbed me, stroked hard. 'Oh!', she exclaimed. 'Feeling you hard and throbbing makes me want to come as well!'. In seconds her own hand on her clit brought her pleasure.
Her breathing did not return to normal before a minute or two had passed. Then she handed me a roll of paper towels and I began to mop my cum off her thighs and desk.
'I don't think you're going to be rising in class!' she said, with her usual impish grin.
