I'll give you half the bed, and you give me blowjobs and sex: a deal with my step-aunt

An aunt came to visit an ordinary American family... well, not a biological aunt, but a step-aunt, since our hero lived with his stepmother and this was her sister. There were no free bedrooms left in the house, so she was assigned to the boy's room. At first, he wasn't happy about it, but then he realized how to benefit from it. Agreeing to let his step-aunt share his bed, the guy easily persuaded her to relax and have forbidden sex with him.
