Nick arrived at his girlfriend's house looking forward to a great time. Irene was as hot as they come, in amazing shape, and they had the whole day to work those three things out.
Their mouths met one another's as soon as Nick came in, feeling up his hot 20-year-old girlfriend. Both had the hot summer day off from school and work and planned to make the most of it. Irene grabbed his cock through his pants to assure he was ready and they hit the couch in the living room. Irene straddled him, her loose thin shorts allowing her to feel everything he was packing and what she would soon be enjoying. Nick whipped off his own shirt, then hers, her lithe muscular body appearing and being grabbed all over. Irene worked on Nick's pants button and they worked together to slide them off, no foreplay today, they had business to attend to. Irene's shorts came off with his revealing no panties and a ready pussy. She spat into her hand and lathered Nick's swollen head before giving her own slit a rub to ensure they were ready.
She sat down on top of him and worked her way down onto his hard dick. Mouths still entwined, Nick lowered his hands to Irene's hips, guiding her and helping her slam her firm shapely ass down onto his needy cock. She was tight and warm and wet and riding him for all he was worth, satiating his own need for pleasure, as well as his need to give it. Nick slapped Irene's perfect muscular ass with one hand and grabbed her neck with the other as he asserted his dominance over her and gave her exactly what she wanted: to be taken control of.
Just then, Nick saw movement behind Irene, someone had walked from the hallway to the kitchen. He was worried about her parents being there, but they probably would have stopped them by now, so he continued his good work, as Irene would not notice anything except him slowing down at this point. Looking behind her he then saw her 19-year-old sister Anna appear in only a purple bikini and headphones, and only then noticed the two lovers on the couch. It would appear Anna was headed for the pool but stopped in the kitchen for a snack. Anna did not move for a moment, as the heated lovemaking ensued.
