A strange tingle wakes him

He awoke with a tingling in his head kind of like his Spidey Sense, but softer with an almost pleasant edge to it. His Spider Sense never felt quite like this before. It was pulling him in a direction: to the left and slightly down.

Quickly, he donned his Spiderman outfit. He had to figure out what was going on. He opened his window and crawled out on the wall of the building, gripping the bricks with his preternaturally sticky hands and feet. The pull felt like it was coming from just a floor or two down and around to the other side of the building. He started crawling in that direction.

Peter was now directly above where this sense was pulling him. A window two floors lower seemed to be the target. He approached the window carefully, not wanting to give away his presence. He peered in.

Inside was a bedroom lit by a dozen candles. He moved around to get a good view through the partially open curtains. A low moan came through the open window, and, at first, Peter thought it was someone in pain. However, something moved on the bed, and he could now see two bodies entwined head-to-tail in a sixty-nine position. The next louder moan sounded like sexual arousal. As he peered inside, he could see two pairs of breasts and realized that it was two women having sex. His cock hardened inside his Spiderman suit.

The two heads moved rhythmically, and the moans turned to growls and heavy panting. Peter removed one of his gloves, tucking it securely into the waistband of his tights, and eased the bare hand down his pants. He stroked himself as he watched.
