Rachel smiled at Mark, and left the room.
Mark continued playing with his nipples, wondering what Rachel was up to. A few moments later, she came back and pushed Mark onto the bed.
"Lay back and relax" she said, taking off first her shirt and pants. She stood back up, letting her firm tits bounce free. Mark was practically drooling, his male mind confused as his fingers traced his nipples.
She took off her jeans, sliding them down her sexy legs. She practically ripped off her panties...exposing her huge, 10 inch cock!
Mark reveled in the sight, the sexy form in front of him; Rachel's face was so hot, her tits looking so nice, her shapely, tight, athletic body leading down to the monster between her legs.
Mark's male mind was initially repulsed, but at the same time his female body had a sudden yearning for the cock. "Jesus, Rachel....is it big enough?"
"I don't know, let's find out...come here!" She said as she pulled his head toward her crotch.
"Rachel, no. I don't want to...I just don't....uhh...ohhh" He began to protest, but suddenly couldn't as her hand slid down to his clit, rubbing it, slowly sliding back toward Mark's new hole and gently sliding inside. She quickly stopped.
"Ung don't stop" Mark moaned.
"Help me out first." Rachel smirked. She new he had him.
Mark gave in, his sex driving his decisions. Rachel laid down, her hand slowly pumping her currently flaccid organ. Mark leaned down and ran his tongue around the tip, feeling it twitch with anticipation. Rachel leaned her head back, "Mmmmm" was all she could get out. She moved her hands to her tits, gently encircling her hard nipples.
Mark took her entire cock in his mouth as it hardened to its full 10 inches. He cupped her balls as he sucked. He engulfed her cock and slid his tongue around its length. Rachel moaned with delight "Yessss Mark keep that up! Ohh you are a natural cocksucker!"
Mark slid a finger between Rachel's legs and was surprised at what he found. Rachel still had her pussy! He slid a finger in, then two, pumping her and rubbing her clit as he sucked her off.
"OH MY GOD OHHHHHH MY GOD!!!! MARK OHHHHHHHHH!!" Rachel screamed. She was so busy with growing her cock for sweet Mark that she completely forgot about her pussy.
Rachel couldn't take any more between her nipples, pussy and dick, and her cock erupted into Mark's mouth as her pussy creamed his fingers hard. Mark swallowed it all but Rachel just wouldn't get soft.
"Rachel I need you now.." Mark begged.
"Lay down, sexy." Rachel insisted.
Mark laid down on the bed and spread his legs wide. His male mind screamed that this was wrong but his body needed it. Rachel moved between his legs and pressed her monster square on his pussy lips. Mark moved his hips, trying to slide her inside him. She moved back and slid her dick along his lips, teasing his clit.
"Ung Rachel stop and put it in me!" Mark moaned.
She put her lips to his nipples and gently sucked, causing Mark to moan louder. His hand grabbed the other nipple while his other hand slid down to play with his clit. He rubbed it then moved his hand to her cock, rubbing it. Rachel couldn't take anymore and slid between his lips, feeling first the head then shaft slide into him.
Rachel was in awe. "Oh my...Mark you're so tight! Mmm that's fantastic!"
Mark could not believe the feeling of her cock in him. He felt so full and tight, like he was complete. Rachel started to thrust, ramming into Mark's tight, wet pussy, her balls slapping his lips, her tits swaying and jiggling with each thrust.
"Ungg...ngg...ohhhh Rachhh!" was all Mark could say between thrusts, he was lost in the sensations. His hands were glued to his tits, twisting and pulling his nipples.
Mark put her hands on Rachel's back, holding her loosely as she thrusted. She lowered her body to his, kissing him full on, moaning into his mouth. Her nipples rubbed his, causing them both to moan in delight. Mark felt a warmth in his pussy, suddenly spreading through his body as he came for the first time as a woman.
"OHHHHHHHH" he screamed.
Rachel pumped faster and faster, harder and harder, getting closer to cumming. The feeling of Mark's pussy contracting on her dick was better than she could have imagined, but she pressed on.
Mark's orgasm kept going, and suddenly Rachel paused and gave a big, hard thrust, and groaned. Mark felt warmth in his pussy and had a final orgasm. As Rachel came, she slowed, both of them breathing heavily. She laid down on top of him, kissing him deeply, their bodies pressed together in embrace, her dick still buried inside him and their large firm tits pressed together.
"Wow...that was...amazing" said Rachel. Mark was speechless. Rachel pulled out and left to clean up, her tits and still semi-hard cock bouncing as she left.
While she was gone, Mark found the energy to move again and looked over at the box of chocolates. He went and picked one up.
