Grandad was a tall, muscular man in his 60s with piercing blue eyes and a thick beard.He was well-built and had an impressive pair of biceps that rippled under his shirt as he stood over the young teenager girl lying on the bed.Teenager was a beauty, with long blonde hair that cascaded down her back in waves of silky strands.She had big round tits, perky nipples that jutted out of her low cut top, and a flat stomach that was accentuated by the tight black lace thong she wore.Grandad couldn't resist the temptation to touch her and ran his hand along her shoulder before pulling her up into a standing position and turning her around so she was facing him.He took in her entire body, admiring every inch of her that was exposed.He couldn't wait to get between her legs and see how tight her pussy would feel as he thrust his cock deep inside her.As he pulled her down onto the bed again, he grabbed her wrists and bound her hands above her head, holding them firmly so that she couldn't move or escape his advances.Then he knelt down between her legs, pulling her thong down to reveal her wet pussy.He couldn't wait to feel the heat of her pussy against his hard shaft as he buried himself deep inside her.He watched as her breasts bounced with each thrust, their firm nipples puckering as she moaned with pleasure.He didn't care how long they fucked, as long as he could keep sliding in and out of her pussy.As he began to cum, he pushed himself deeper into her, feeling her muscles tighten around his cock as she came.He watched as a stream of juicy cum shot out of her pussy, landing on his face and neck.He pulled his cock out and watched as a large glob of sticky cum exploded onto the bed, landing squarely on teenagers clit.He laughed as he watched her squirm and writhe, trying to catch the last few drops before they slipped away.Thanks for letting me take control, grandad said to her.But I think it's time we switch positions.With a grin on his face, grandad walked over to the bed and straddled teenagers back, pushing her against the mattress as he lifted her hips off the bed.He couldn't wait to see the expression on her face as he plunged his cock into her from behind.Teenager let out a loud gasp as she felt grandads thick rod enter her from behind, filling her up from the back to the front.She arched her back and pushed her ass against him as he plowed her harder and faster.As he started to cum, he reached under her and gripped her thighs tightly, pulling her close to his body as he erupted deep within her.She let out a scream of pleasure as he pumped his cock several times, releasing wave after wave of hot cum deep within her.Finally, with a pop, grandad released his grip on teenagers thighs, allowing her to slide off his back and roll onto her side, panting heavily.She couldn't help but feel satisfied as she watched his thick cock shrink before disappearing beneath the covers.Teenager smiled as she watched him go, already eagerly anticipating their next meeting.
