In The Bank Manager's Cupboard - Part Twenty.
                        CHAPTER EIGHT.

Karin didn't return for hours, it must have been around
midnight when David heard voices, then giggling and
laughing coming up the stairs. Finding it complicated
to kneel, he again bent over and peeked through the
keyhole. He was inflamed with jealousy and desire as he
saw Karin, with a man. They were necking, and stroking
their hands over each other's bodies. She was now
beside her bed, groping him. Her passion astounded
David, as he watched her squirming her body against the
man. She was panting, hot with lust.

What David could not know was that Karin's arousal was
partially, if not mostly stimulated by the thought of
making David watch. The other man was just another
object to be used in her games. With some difficulty in
the restricting outfit David knelt, squashing his
genitals against the floor, further adding to his
discomfort and indignity in order to get his eye
against the keyhole.

Karin tore at the man's belt, and dropped his trousers
and underpants as she fell back upon the bed, pulling
him with her. She wriggled to help the man pull off her
panties and moaned with pleasure as she pulled him on
top of her. She helped him enter her, and he instantly
started bucking and pumping. Certain that David would
be watching, Karin looked towards the door and groaned
in ecstasy. She was moving vigorously up against the
man, meeting his thrusts, as she rushed headlong
towards her climax. Her first orgasm came in seconds
and she pushed the man down the bed towards her vulva.
His face was soon in position and as his tongue pushed
deep into her, Karin's hand moved in a blur against her
clitoris.

David felt humiliated by his own position as he watched
Karin's face, he had never seen a woman's face express
so much ecstasy and pleasure. After her second climax
she pulled the man back up her body, and as the man
pumped towards his own climax Karin's face contorted
with her cries of pleasure as orgasm followed orgasm.
The man slumped onto Karin as he pumped his own seed
deep within her.

Karin and the man collapsed together on the bed for
quite a while, apparently recovering from their
passion. Eventually David saw Karin kneel up and crawl
down the bed, she turned her back to David so that his
view was between her parted legs. There she sucked the
man back to erection. David watched Karin's own hand go
between her parted thighs as she knelt so blatantly
exposed to him. Karin toyed with herself as she licked
and sucked the man's genitals. This was perhaps the
greatest of all humiliations for David. To see the
woman he revered give herself to another in that way,
the woman who denied him so much. He heard them both
moan as the man obviously came in her mouth.

How could she, after all she said about men, behave in
such an abandoned manner with another? It didn't make
sense to him! She must like it both ways? Then why not
with him?

It must have been long past one in the morning before
they had both left the room. Karin was again
respectable, her panties replaced and now wearing a
negligee. David returned to sit on his bed in abject
misery. Some ten minutes later her voice announced over
the speaker to David, "That was a real man in action,
wanker." Karin must be alone downstairs, he concluded,
as he heard her laughter before she released the
microphone button. She must have known he would be
watching, and she had obviously enjoyed that knowledge.
