Go relieve yourself

The only thing you could think of was Lin; the softness of her lips, her warm breath on your ear and of course the heavy meaty impact of her massive cock against your chest. Your cock was as hard as a rock, your hand instinctively went down to your briefs looking for relief. Your own cock never felt so ridiculously small as in that moment. You knew girls were always larger than boys, and not by a small margin, but Lin was a whole new level of superiority. Just thinking of that size contrast made you go over the edge. You cleaned up quickly and decided to go raid the fridge for a late snack.

On the way there you run into all four girls. Your eyes went straight to Lin, you never noticed before but she was a couple of inches taller than even your sister. Your eyes went over those delicate lips and then down to the massive bulge in her pants. Even though you just jacked off you could feel a stirring in your pants.

"Oohhh Lin, I think Dougy here likes you. He can barely see the rest of us." Crystal was saying, noticing how you were staring at Lin.

Tearing your eyes away from Lin you could see the other girls smiling at you.

"Hey Lin, go stand next to the little nerd I want a photo of the two of you together." Crystal continued.

"N.. No problem. I'd be delighted." You spoke stuttering to the amusement of the girls.

As she approached you, her full height became clear. She was over a head taller than you, you were shoulder level to her. She stood right behind pressing the tips of her perky B-cups into the back of your shoulders, and more importantly about a foot of ridiculously thick cock was pressed between your ass cheeks, thighs and back. She crossed her long arms around you and brought her face close to yours for the photo.

"I hope I didn't distract you too much from your homework before, I plan to get back to you about a very large problem." Lin whispered into my ear pressing her erection harder against my back. Crystal took the photo and then the girls started laughing hard, pointing at the small tent in your pants.

"Come on girls let's go before he pops." One of the other said, and they all started walking away laughing. Lin licked my ear again, and left after the other with a smile on her face.

It took you a very long moment to remember where you were originally even going. Your mind was preoccupied with the feeling of Lin's erection pressing into your back, you could feel her size against your ass cheeks and she seemed even bigger than before. Your hands were now shaking even harder in a mix of lust and fear. Did she say she was going to visit you again?

Should you try to run, lock your room or just relax. Maybe she as just making fun of you, it wouldn’t be the first time your sister’s friends were making fun of you. So after a brief deliberation and a short meal you decide to…
