This happened about a year ago. This one time I had a fwb come hang out while my homies were there. We all drank and gamed for a while. We were all having fun but after a while my fwb went and sat on the couch. I didn’t want to leave her alone so handed the controller over and told my friend that I was going to take a break for a bit. I went and sat down and kissed her. She immediately reached over to feel my bulge. I stopped her hand and signaled that my friends were still here. She put her finger over her lips for me to shush and grabbed a blanket and put it on our laps. She then undid my pants and pulled my cock out and started stroking it. I was admittedly nervous. I’ve done things with people around before but more at big parties with random people. This was a small group of friends and me and her. I talked over to my friends, joking about the game and for them to do some longer matches so that they stayed distracted. She kept stroking me making me hard and I kisses her again. Then with little warning she quickly popped onto my lap. She had a skirt on and slid her panties to the side. I was taking back but she had worked me up and she was already on my lap so I said fuck it and guided my cock into her pussy. She let out a small gasp trying to stay quiet. Luckily I had raised the game volume with the remote through my phone. I glanced over towards my friends to make sure they were still distracted then gropped my fwb tits as she rode me. She was a bit on the thick side and had enormous tits. I loved grabbing them and bit them through her shirt. I didn’t want to risk pulling them out. She rode me for about 10 minutes before I saw the match my friends playing coming to an end. I signaled to her and she got off and covered up and sat back next to me with her head on my shoulder as i buttoned up my pants.
Afterwords my friends left not too long after and I quickly locked the door behind them and turned to see her already undressing. I showed my graduate by getting on my knees and eating her pussy before leading to a night of pounding her silly.
