Not in wet underwear

"Not until you've dried off." There mother tells them, looking at them sternly. "I'm going to go and get you a towel, while I do you can take off that wet underwear."

"What?" Mike asks in shock, looking from his sister to his mother and back again. "We can't just get naked in the garden!"

"You should have thought about that before making such a mess." Their mother shot back before heading back into the house.

Mike turns to his sister for help and is shocked to see her bra is already in the floor, her breasts on full display. "Rose?"

"I just want to get this humiliation over." She replies, sliding off her maroon underwear and leaving her stood completely naked in the middle of the back garden in front of her brother. "You should do the same." She added, quickly covering herself with her hands.

Taking a deep breath Mike slips his fingers into the waistband of his boxers, sliding them down and feeling his face flush as a semi hard cock springs into view. Kicking off the boxers he quickly grabs his cock in both hands, trying not to think of his completely naked sister stood in front of him.

Their mother seems to have taken forever to get back to them, before finally returning to the garden, both teens shocked when they see her. All she has bought with her is a single hand towel.

"What are we supposed to do with that??" Rose asks.
